Using Large Language Models to Improve Keyword Difficulty Predictions: A Practical SEO Scoring Workflow

Keyword difficulty scores look precise, but they are often rough estimates built from a narrow set of signals. A tool may count referring domains, inspect domain authority, or assess the top-ranking pages, then compress all of that into one number. Useful, yes. Complete, rarely.

Large language models can improve this process by adding contextual judgement to the score. They can review search intent, content depth, SERP patterns, topical relevance, brand strength, internal linking, and keyword cannibalisation risk in one connected workflow. When combined with conventional SEO data, this creates a more realistic opportunity score for each keyword.

That distinction matters. A keyword with a difficulty score of 35 might be highly competitive for your site, while a keyword scored at 55 could be attainable if it aligns closely with your existing topical authority. The practical question is not simply, “How difficult is this keyword?” It is, “How difficult is this keyword for this website, with this content plan, at this stage?”

This guide explains how to build that scoring system, how LLMs can support it, and how SEO Letters, the AI blog writer for structured SEO publishing can help you move from keyword research to finished content without the usual copy-and-paste workflow.

Why conventional keyword difficulty scores are incomplete

Traditional keyword difficulty tools typically use a combination of:

• The number and quality of referring domains pointing to ranking pages
• Domain-level authority or rating
• Page-level authority
• SERP features
• Estimated search volume
• The age and strength of competing domains
• Historical ranking behaviour
• Content relevance

These signals are valuable, but they tend to describe the ranking environment rather than your own ability to compete within it. The result is a generic score.

A generic score can hide several important variables:

• Your website may already have strong topical authority around the subject.
• Your competitors may rank with weak, outdated or poorly structured content.
• The SERP may be dominated by forums, thin category pages or irrelevant results.
• Search intent may be mixed, creating an opportunity for a better-focused article.
• Your site may already have several pages targeting similar terms.
• A keyword may appear achievable but require a link-building campaign that does not fit your budget.
• The search volume may look attractive while the commercial value remains low.

This whole thing becomes more complicated when keyword cannibalisation is involved. If three pages on your site target similar phrases, the difficulty of ranking a new page is not only determined by the external SERP. Your own information architecture may be weakening the signal.

The difference between external difficulty and strategic difficulty

It is useful to separate keyword difficulty into two categories:

Difficulty type	What it measures	Typical signals
External difficulty	How difficult the current SERP appears	Referring domains, authority, content quality, SERP intent
Strategic difficulty	How difficult the keyword is for your specific website	Topical authority, internal links, existing pages, brand fit, content resources
Operational difficulty	How difficult it is to produce and maintain the content	Research time, expert review, refresh frequency, media requirements
Commercial difficulty	How difficult it is to generate business value	Buyer intent, conversion potential, competition from commercial landing pages

A useful LLM-assisted workflow combines these categories into one prioritisation model. It does not blindly replace a keyword tool. It interprets the available evidence and helps you make a better decision.

What large language models add to keyword difficulty scoring

LLMs are particularly useful when the input includes structured SEO data and clear evaluation criteria. They can identify relationships between factors that are difficult to capture in a single numerical metric.

For example, an LLM can compare:

• The exact wording of a query with the content type dominating the SERP
• The needs implied by the query with the structure of ranking pages
• The current page on your site with other pages targeting related terms
• The authority required by competing results with your current authority profile
• The keyword’s commercial intent with the products or services you actually offer

This is not magic. The model needs reliable inputs, controlled prompts and human review. If you provide only a keyword and ask whether it is difficult, the answer will usually be generic.

The five useful LLM analysis layers

An effective workflow asks the model to analyse five connected layers:

1. Query meaning: What does the searcher actually want?
2. SERP composition: What types of pages rank, and what common patterns do they share?
3. Content gap: What is missing, weak or outdated in the current results?
4. Site fit: How well does the keyword match your authority, products and existing content?
5. Cannibalisation risk: Could a new page compete with a page you already have?

The output should be a decision rather than a vague description. You want the model to recommend one of the following:

• Publish now
• Publish after creating supporting content
• Consolidate with an existing page
• Target a narrower variation
• Build a landing page instead of an article
• Monitor the term but defer publication
• Reject the keyword

A practical scoring model for keyword difficulty

You can create a composite score that combines tool data, LLM analysis and your own business judgement. A simple model might look like this:

Adjusted Keyword Difficulty =
External SERP Difficulty
+ Intent Competition
+ Authority Gap
+ Content Depth Requirement
+ Cannibalisation Risk
- Topical Authority Advantage
- Content Gap Opportunity
- Internal Linking Advantage

The final score can be normalised to a 0 to 100 scale. It is not intended to imitate a proprietary platform. Its purpose is to create a consistent decision framework for your team.

Recommended scoring dimensions

Dimension	Weight	What to evaluate
External SERP difficulty	25%	Authority, links and strength of ranking pages
Search intent competition	15%	How clearly established the dominant intent is
Content quality requirement	15%	Depth, originality, evidence and format needed
Site authority gap	15%	Difference between your site and ranking competitors
Topical authority advantage	10%	Existing relevant content and expertise
Content gap opportunity	10%	Weaknesses or omissions in current results
Cannibalisation risk	10%	Overlap with existing pages and ranking terms

You can adjust the weights by site type. A new affiliate site may need to increase the authority gap weighting. A recognised publisher with strong links may give greater weight to content gaps and intent quality.

Example scoring rubric

Score	Interpretation	Recommended action
0 to 20	Low difficulty and strong site fit	Publish or add to the next campaign
21 to 40	Achievable with good structure	Publish with internal links and clear intent targeting
41 to 60	Moderate competition	Build supporting content and assess conversion value
61 to 80	High competition	Target a narrower angle or wait for more authority
81 to 100	Very difficult or poor fit	Reject, consolidate or revisit later

This is a planning tool, not a ranking guarantee. Search results change, competitors publish new pages and Google can reinterpret intent over time.

Step 1: Collect the right keyword and SERP data

LLM analysis becomes much more reliable when you provide a structured evidence pack. At minimum, collect:

• Primary keyword
• Keyword variations and related questions
• Search volume
• Existing keyword difficulty score
• Current ranking URLs
• Ranking page titles
• Referring domain counts
• Domain authority or comparable authority metric
• Content format
• Search intent classification
• Your own relevant URLs
• Existing rankings for related terms
• Conversion value or business priority

A spreadsheet is enough for a small project. Larger teams may connect an SEO platform, a crawler and a content system through an API.

The input should describe the SERP rather than only listing a difficulty number. For example:

Keyword: best email marketing software for charities
Volume: 1,000 monthly searches
Tool difficulty: 48
Ranking formats: listicle, software comparison, charity-specific guide
Top results: 3 commercial comparison pages, 4 editorial guides, 2 vendor pages
Common weaknesses: limited charity-specific pricing information, shallow compliance guidance
Our site: marketing software provider with 22 relevant articles and 6 referring domains to the category page
Existing related pages: best email marketing software, email marketing for nonprofits, charity email campaigns

That gives the model enough context to identify strategic opportunity and cannibalisation risk.

Step 2: Classify search intent before judging difficulty

Intent is one of the most important missing components in many keyword difficulty scores. A keyword can look moderately competitive while being difficult because every ranking page satisfies the same very specific intent.

Classify the query into a primary intent category:

• Informational
• Commercial investigation
• Transactional
• Navigational
• Local
• Freshness-driven or news-related
• Mixed intent

Then identify the required page type:

• How-to guide
• Definition page
• Comparison article
• Product landing page
• Category page
• Review
• Case study
• Template or tool
• Local service page
• News or trend article

An LLM can help compare the query with the visible SERP. Use a prompt such as:

Analyse the following keyword and ranking-page data.

Keyword: [insert keyword]
Ranking titles: [insert titles]
Ranking URLs and page types: [insert data]

Return:
1. Primary search intent
2. Secondary intent
3. Dominant content format
4. Whether intent is stable or mixed
5. The minimum content elements a page would need to compete
6. Whether a new article, landing page or consolidation is most appropriate
7. A competition score from 0 to 10, with evidence

The key point is that the model should explain its score. An unexplained rating has limited value during a content planning meeting.

Why intent affects keyword difficulty

Suppose the keyword is “keyword cannibalisation”. The SERP may include:

• Definition pages
• Technical SEO guides
• Audits and troubleshooting articles
• Product pages from SEO platforms
• Case studies
• Video results

A page that only defines the term may rank for informational searches but fail to address diagnosis and remediation. The difficulty is not caused solely by authority. It is caused by the need to satisfy several connected needs in one coherent resource.

Step 3: Use LLMs to inspect SERP content quality

A difficulty score may treat ten ranking pages as strong competitors even when many are mediocre. LLMs can help you inspect those pages at scale, provided you use extracted page content or carefully prepared summaries.

Ask the model to evaluate:

• Topic coverage
• Accuracy and evidence
• Original experience
• Use of examples
• Clear process steps
• Definitions and terminology
• Internal linking
• Visual assets
• Product or service neutrality
• Date freshness
• Author expertise
• Structured data opportunities
• Readability and page structure

Use a scoring matrix rather than a single quality label:

Quality factor	Score from 0 to 5	Evidence to capture
Intent match		Does the page answer the actual query?
Topic completeness		Are important subtopics missing?
Practical usefulness		Does it include steps, examples or templates?
Original insight		Is there first-hand experience or unique analysis?
Trust signals		Are authorship, sources and credentials clear?
Freshness		Is the information current and maintained?
Content structure		Can users find answers quickly?

A low average score across the SERP may indicate a content gap, even if the competing domains have strong authority. That does not make the keyword easy. It suggests that a genuinely better page may have a route into the results.

This is where a publishing system becomes important. SEO Letters can turn the approved keyword and content brief into a structured article with headings, internal links, schema and images, while keeping the workflow connected to keyword research and publication.

Step 4: Measure your topical authority advantage

Topical authority is not a single universally agreed metric, but it can be assessed through observable indicators. Your site may have a meaningful advantage when it has:

• Several relevant pages covering the core topic
• Strong internal links between related pages
• Consistent expert-led information
• Links from relevant websites
• Existing rankings across the topic cluster
• A product or service closely connected to the subject
• Historical traffic and engagement for similar content

An LLM can compare your existing content inventory with the keyword’s topic. Give it the titles, URLs, target terms and organic performance of relevant pages.

Ask it to return:

• Topic clusters already covered
• Missing subtopics
• Pages that should support the new article
• Pages that might compete with the new article
• Suggested internal anchor text
• Recommended hub and spoke relationships
• An authority advantage score from 0 to 10

A useful topical authority calculation might be:

Topical Authority Advantage =
Relevant Ranking Coverage
+ Internal Link Strength
+ Expert Relevance
+ Existing Backlink Relevance
+ Product or Service Alignment

Keep the scoring consistent. If one analyst gives a site a 9 and another gives it a 4, the framework is not yet operational.

Step 5: Detect keyword cannibalisation before publishing

Keyword cannibalisation occurs when multiple pages on the same site appear to target the same search need, causing search engines to divide ranking signals or choose a page you did not intend to prioritise.

It is often misunderstood. Two pages can rank for similar keywords without causing a problem. The real warning signs include:

• Two pages have the same primary intent
• Both pages receive impressions for the same query set
• Rankings alternate between the pages
• Neither page has a clear topical role
• Internal links point to both pages using similar anchor text
• One page is weaker but is selected by Google
• The pages overlap heavily in their main sections
• Traffic declines after publishing a near-duplicate page

Before assigning a keyword to a new article, compare it with your existing URLs.

Cannibalisation audit table

Existing URL	Main topic	Search intent	Ranking terms	Overlap risk	Suggested action
/keyword-research-guide/	Keyword research process	Informational	Keyword research, SEO keywords	Medium	Keep as broad guide
/keyword-difficulty/	Difficulty scoring	Informational	Keyword difficulty, SEO difficulty	High	Rework or consolidate
/keyword-difficulty-tools/	Tool comparison	Commercial	Keyword difficulty tool	Medium	Keep as comparison page
/keyword-cannibalisation/	Diagnosis and fixes	Informational	Keyword cannibalisation	Low	Publish as separate guide

An LLM can compare these pages for topical overlap, but it should not make consolidation decisions without data. Check organic clicks, impressions, backlinks, conversions and historical ranking changes before redirecting a page.

A cannibalisation risk formula

You can score risk using four factors:

Cannibalisation Risk =
Intent Overlap x 0.35
+ Query Overlap x 0.25
+ Content Similarity x 0.25
+ Internal Link Ambiguity x 0.15

Score each component from 0 to 100.

Risk score	Meaning	Action
0 to 20	Minimal overlap	Proceed with normal planning
21 to 40	Some similarity	Define the page’s unique role
41 to 60	Material overlap	Consider restructuring or narrowing
61 to 80	Serious cannibalisation risk	Consolidate or assign separate intents
81 to 100	Duplicate strategic target	Do not publish without resolving overlap

This is one area where LLMs are useful as an early warning system. They can spot semantic similarity across hundreds of page titles and briefs far faster than a manual review. They cannot reliably determine business importance or backlink equity on their own.

Step 6: Adjust the score for content and link requirements

Two keywords with the same external difficulty may demand very different resources.

For example:

• “What is keyword cannibalisation?” may need a clear explanation, examples and simple fixes.
• “Best enterprise SEO platform” may need product comparisons, pricing context, original testing, expert commentary and strong commercial authority.
• “How to fix keyword cannibalisation in Shopify” may require platform-specific instructions and screenshots.

Rate the expected resource requirement across these areas:

Resource area	Low requirement	High requirement
Original research	General explanation	Survey, testing or proprietary data
Subject expertise	Basic SEO knowledge	Specialist or regulated expertise
Content depth	1,000 to 1,500 words	Comprehensive multi-section guide
Visual assets	Basic graphics	Screenshots, diagrams or video
Link acquisition	Existing authority may suffice	Outreach or digital PR likely needed
Maintenance	Annual review	Monthly or quarterly refresh
Conversion strategy	Simple CTA	Product comparison and lead funnel

An LLM can estimate the likely content brief, but you should validate the recommendation against your team’s production capacity. A keyword with excellent potential may still be a poor choice if it cannot be maintained.

Step 7: Create an LLM prompt that produces useful scoring

Poor prompts create soft commentary. Good prompts create a repeatable assessment.

Use a fixed prompt structure with defined inputs, scoring ranges and output fields:

You are assessing keyword opportunity for an SEO content team.

Evaluate this keyword for our website using only the evidence provided.

Keyword: [keyword]
Search volume: [volume]
Current tool difficulty: [score]
CPC or commercial value: [data]
Ranking-page data: [URLs, titles, authority, links, formats]
Our relevant pages: [URLs, titles, rankings, traffic]
Our topical authority evidence: [cluster summary]
Business relevance: [description]
Known content gaps: [summary]

Score each factor from 0 to 100:
1. External SERP competition
2. Intent competition
3. Content quality requirement
4. Authority gap
5. Topical authority advantage
6. Content gap opportunity
7. Cannibalisation risk
8. Commercial value
9. Expected production effort

Calculate:
- Adjusted keyword difficulty
- Opportunity score
- Cannibalisation risk
- Recommended action

Return:
- A scoring table
- Evidence for every score
- The main uncertainty
- The ideal page type
- Required supporting content
- Internal links to add
- A six-month review KPI

Set clear rules for the final recommendation. For example:

Recommend PUBLISH when opportunity is at least 65, adjusted difficulty is below 55 and cannibalisation risk is below 40.

Recommend SUPPORT FIRST when opportunity is at least 60 but topical authority is below 50.

Recommend CONSOLIDATE when cannibalisation risk is above 60.

Recommend REJECT when business relevance is below 40 or production effort is above 85.

These thresholds are not universal. They are starting points. Your team should recalibrate them using actual ranking outcomes.

Step 8: Build an opportunity score, not only a difficulty score

Difficulty alone does not tell you whether a keyword is worth pursuing. Add commercial value, strategic relevance and expected traffic contribution.

A practical opportunity formula could be:

Opportunity Score =
(Commercial Value x 0.25)
+ (Content Gap x 0.20)
+ (Topical Authority x 0.15)
+ (Traffic Potential x 0.15)
+ (Conversion Fit x 0.15)
+ (Freshness or Trend Potential x 0.10)
- Cannibalisation Penalty

The penalty should be substantial when existing pages already compete for the same intent. Otherwise, your system may reward keywords that create internal competition.

Example: comparing three keywords

Assume a software company is planning content around SEO publishing.

Keyword	Adjusted difficulty	Opportunity	Cannibalisation risk	Decision
keyword difficulty score	42	71	18	Publish
keyword difficulty calculator	58	68	32	Publish with supporting content
best keyword research software	76	64	66	Consolidate or defer

The third keyword may have strong commercial value, but the high authority gap and existing overlapping product page reduce its immediate priority. A lower-volume keyword could produce better results sooner.

That is the point of the workflow. You are ranking opportunities, not chasing impressive-looking search volumes.

An example workflow for a content team

Imagine a marketing consultancy with 40 SEO articles, a modest backlink profile and strong expertise in technical audits. It wants to target “keyword cannibalisation audit”.

Initial data

• Tool difficulty: 46
• Search volume: 500 monthly searches
• Search intent: Informational with service investigation
• Ranking pages: General SEO guides, audit checklists and agency service pages
• Existing site content: One broad cannibalisation guide and several technical audit articles
• Business relevance: High
• Internal linking strength: Moderate
• Content gap: Few pages explain how to combine Search Console data with crawl data

The LLM assessment might identify the following:

Factor	Score	Reasoning
External SERP competition	48	Some established SEO sites rank, but several pages are general
Intent competition	55	The SERP mixes guides, templates and services
Content quality requirement	62	A practical audit process is expected
Authority gap	44	The site is weaker than the biggest competitors
Topical authority advantage	69	Existing technical audit content supports relevance
Content gap opportunity	78	Few results provide a repeatable audit workflow
Cannibalisation risk	52	Existing broad guide overlaps with the new term
Commercial value	73	The topic aligns with consulting services
Production effort	58	Requires screenshots, examples and data interpretation

The recommended action would be publish after restructuring the existing broad guide. The new page should focus on the audit process, while the older page should remain a definition and troubleshooting resource.

That separation makes the information architecture clearer:

• /keyword-cannibalisation/: meaning, symptoms and general fixes
• /keyword-cannibalisation-audit/: crawl, Search Console and ranking analysis
• /keyword-cannibalisation-tools/: software and workflow comparison
• /seo-consulting/: commercial service page

How SEO Letters supports this keyword scoring workflow

Keyword analysis is only useful when it leads to consistent publishing. The gap between a content brief and a live page is where many SEO teams lose time.

SEO Letters is an AI blog writer built for that full publishing operation. It can support the workflow by helping you:

• Research keywords and review difficulty ratings
• Build topical authority clusters
• Identify site gaps against competitors
• Generate structured articles with headings and semantic coverage
• Add internal links based on your content architecture
• Create schema and image recommendations
• Produce product-aware affiliate and ecommerce articles
• Publish directly to WordPress, Shopify or webhooks
• Generate content in 21 languages
• Schedule autonomous campaigns
• Refresh existing articles instead of producing only new pages
• Track published content performance through a dashboard

The autonomous scheduler is particularly relevant to keyword difficulty planning. You can define a topic, cadence and publishing destination, then create a campaign that researches, writes and publishes on a regular basis. The strategy remains yours. The repetitive execution is handled inside the system.

Route different workflow stages to different models

SEO Letters also allows you to bring your own AI keys and route stages to Gemini, OpenAI or Claude. That can be useful when your workflow has different model requirements:

• Use one model for broad topic expansion
• Use another for content structure and drafting
• Use a third for editing or multilingual generation
• Apply your own brand voice and content constraints
• Keep the evaluation prompt separate from the writing prompt

This separation matters. The model that scores a keyword should not automatically decide that the keyword deserves a new article. Treat scoring, strategy, drafting and quality assurance as separate stages.

Human review remains essential

LLMs can produce confident assessments from incomplete data. That is the main risk.

A model may:

• Assume a page has strong authority without seeing backlink evidence
• Misread a mixed-intent SERP
• Treat similar wording as true cannibalisation
• Recommend consolidation without understanding conversion paths
• Invent content gaps that are not supported by the pages
• Overestimate the value of search volume
• Ignore brand or regulatory constraints
• Confuse correlation with ranking causation

Use a human approval checkpoint before changing URLs or launching a campaign.

Human quality assurance checklist

• Confirm the top-ranking URLs manually.
• Check whether the SERP has changed since the data was collected.
• Review Search Console query overlap between existing pages.
• Inspect backlinks before redirecting or consolidating content.
• Confirm the proposed page type matches the actual SERP.
• Validate the commercial intent with sales or product teams.
• Check claims, statistics and technical instructions.
• Review the proposed internal links for relevance.
• Approve the final keyword, URL and primary intent in your content brief.

The model should make the process faster and more consistent. It should not remove accountability.

Measuring whether your predictions are improving

A scoring system is only useful if you compare predictions with outcomes. Create a review cycle at 30, 60, 90 and 180 days after publication.

Track:

• Impressions for the primary keyword
• Average position
• Number of ranking queries
• Click-through rate
• Organic sessions
• Assisted conversions
• Direct conversions
• Engagement by landing page
• Internal link clicks
• Ranking volatility
• Cannibalisation changes
• Backlinks acquired
• Content refresh requirements

Prediction accuracy dashboard

KPI	What it tells you
Predicted difficulty versus actual ranking progress	Whether your difficulty model is calibrated
Predicted opportunity versus organic conversions	Whether strategic value is being assessed properly
Cannibalisation risk versus query overlap after publishing	Whether your overlap model is working
Content gap score versus ranking improvement	Whether SERP weaknesses are meaningful
Production effort versus traffic return	Whether resources are being allocated efficiently
Topical authority score versus time to rank	Whether cluster maturity is measured realistically

If your model consistently scores keywords too optimistically, increase the authority gap or content requirement weighting. If it underrates terms where your site already has strong topical coverage, increase the topical authority advantage.

Do not alter the model after every individual result. Review a meaningful sample, perhaps 20 to 50 published pages, then adjust based on patterns.

Common mistakes in LLM-assisted keyword difficulty scoring

Treating the model’s number as objective

The output is an estimate based on the data and rules you provide. It is not a hidden Google metric.

Use ranges and confidence notes. For example:

• Adjusted difficulty: 54
• Confidence: medium
• Main uncertainty: backlink quality of the top three pages
• Recommended validation: manual authority review and competitor link analysis

Ignoring page-level intent

A site may have strong authority but still fail to rank because the content format is wrong. A service page will not always compete effectively with a detailed tutorial, and a general guide may not satisfy a transactional query.

Always score page type and intent separately.

Publishing without checking existing URLs

This is the fastest route to keyword cannibalisation. Before adding a keyword to a campaign, inspect the site’s current ranking pages and query overlap.

A new article should have a distinct job.

Using search volume as the priority signal

High-volume keywords often attract the most mature competitors. Lower-volume terms can be more valuable when they align with a specific problem, product or conversion stage.

Include business relevance and conversion fit in the scoring model.

Creating a perfect score with unreliable inputs

If your keyword volume is outdated, ranking-page data is incomplete or internal URLs are missing, the final score may appear rigorous while being structurally weak.

Good analysis cannot compensate for poor evidence.

A repeatable weekly workflow

If you are managing a content programme, use this process every week:

1. Collect candidate keywords: Add terms from Search Console, competitor research, sales questions and keyword tools.
2. Group semantic variants: Combine close variants and distinguish separate intents.
3. Map existing URLs: Identify current pages, ranking terms and possible overlap.
4. Capture SERP evidence: Record ranking formats, titles, authority signals and content weaknesses.
5. Run the LLM assessment: Use the fixed scoring prompt and preserve the output.
6. Review the scores: Check assumptions, uncertainty and evidence quality.
7. Choose the action: Publish, support first, consolidate, narrow, refresh or reject.
8. Build the cluster: Assign pillar pages, supporting articles and internal link relationships.
9. Create the brief: Define intent, audience, structure, evidence and conversion path.
10. Publish and measure: Use SEO Letters or your existing publishing workflow, then review results against the prediction.

This process avoids the familiar problem of producing articles because a keyword tool shows volume. It ties the decision to the site’s current position and the work required to create a useful page.

Key takeaways for SEO teams

• Keyword difficulty is contextual. The same term can be easy for one site and unrealistic for another.
• LLMs improve interpretation, not raw truth. They are strongest when analysing structured evidence.
• Search intent must be scored separately. Authority alone does not resolve format mismatch.
• Cannibalisation belongs inside keyword planning. It should be assessed before publication, not after rankings decline.
• Content gaps can offset moderate authority weaknesses. A genuinely better page may find an opening in a weak SERP.
• Opportunity is more useful than difficulty alone. Add commercial value, topical authority, production effort and conversion fit.
• Predictions need calibration. Compare scores with rankings, traffic and conversions over time.
• Publishing capacity affects strategy. A keyword is not a good opportunity if your team cannot produce and maintain the required content.
• Automation should support judgement. SEO Letters helps execute the research, planning, writing, optimisation and publishing stages, while your team controls the strategy.

Final recommendation: connect scoring with publishing execution

Large language models can make keyword difficulty prediction more useful by introducing context, semantic analysis and site-specific reasoning. The strongest workflow combines conventional SEO metrics with SERP review, topical authority measurement, content-gap analysis and a clear keyword cannibalisation check.

Start with a manageable dataset. Score 20 to 30 candidate keywords, record the reasoning, publish the highest-opportunity pages and review performance after three to six months. Then refine your weights.

If you want to move from scoring to execution, use SEO Letters to build and publish your SEO content campaigns. It connects keyword research, topical clusters, site-gap analysis, structured AI writing, internal linking, multilingual content, content refreshes and scheduled publishing in one operational workflow. If you need a specific route for support or a tailored discussion, use the rightbar to make contact.
