Seeing a keyword difficulty score of 70 can make a promising topic look impossible. Meanwhile, a keyword marked “easy” can turn into months of publishing work without ever reaching page one.
The problem is not necessarily the SEO tool. It is how we interpret the number.
Most keyword difficulty metrics compress a complicated search landscape into a single score. Depending on the platform, that calculation may emphasize backlinks, domain strength, SERP competition, topical relevance, or several factors combined.
Ahrefs, for example, bases its KD metric primarily on referring domains pointing to top-ranking pages, while Semrush also offers a domain-specific Personal Keyword Difficulty metric that considers relevance and competitive context.
Learning how to evaluate keyword difficulty beyond traditional SEO metrics means looking at the actual ranking environment.
Search intent, content quality, site relevance, SERP weakness, freshness, authority, and business value all matter. Once those factors are considered together, some intimidating keywords become realistic opportunities – and some supposedly easy ones become much less attractive.
Understand What Your Keyword Difficulty Score Actually Measures
The first mistake is assuming every SEO platform means the same thing when it displays a difficulty score.
They do not.
Ahrefs currently calculates Keyword Difficulty largely from the number of referring domains pointing to pages ranking in the top 10. It explicitly notes that its score does not account for on-page factors.
That makes the metric useful for estimating backlink competition, but not necessarily total ranking difficulty.
Semrush takes another approach with Personal Keyword Difficulty.
Rather than evaluating only general competition, PKD estimates how difficult ranking may be for a specific domain by considering thematic relevance, the competitive landscape, and characteristics of both your domain and ranking competitors.
The lesson is simple: understand the formula before trusting the score.
A KD of 45 is not a universal statement that a keyword is “medium difficulty.” It is an estimate produced by a specific methodology.
Use difficulty scores as filters, not final decisions.
Study the Actual SERP Before Rejecting a Keyword
The search results themselves are often more useful than the number beside the keyword.
Open the first page and study every major organic result.
Ask whether the ranking pages actually answer the query well.
A keyword might have high difficulty because several ranking URLs have powerful backlink profiles. But those pages could still be outdated, poorly targeted, shallow, or written for the wrong audience.
That creates what Ahrefs describes as potential “cracks” in a SERP – weaknesses that a general KD score may fail to reflect.
Its current keyword difficulty guidance specifically recommends examining factors such as content freshness rather than relying entirely on aggregate backlink metrics.
For example, imagine the top results for:
“best CRM for architecture firms”
are mostly generic CRM roundups.
A specialized article comparing workflows, project pipelines, client communication, integrations, and pricing specifically for architecture firms may have a meaningful competitive advantage.
The backlink numbers did not change.
Your ability to satisfy the query better did.
Evaluate Search Intent Alignment
A strong domain can still struggle when its content format does not match what users expect.
Suppose you want to target:
“best budget espresso machine.”
If the SERP contains almost entirely product comparisons, publishing a 3,000-word history of espresso machines will probably not work well.
The article may be excellent.
It is simply answering a different question.
Intent alignment is one of the most important hidden components of ranking difficulty.
Look at whether Google favors:
Comparison pages, tutorials, category pages, product pages, videos, forums, definitions, or first-hand reviews.
Then examine how consistent the results are.
If nine of ten pages use the same format, intent is probably relatively clear.
If results contain reviews, tutorials, product pages, Reddit discussions, and videos, the query may have mixed intent. That can sometimes create more room for a differentiated page.
Google’s own guidance emphasizes substantial, useful content created primarily for people and asks whether the page provides original information, analysis, or a complete treatment of the topic.
Difficulty therefore depends partly on how well you can satisfy the real search need.
Compare Your Topical Strength With Ranking Competitors
Traditional difficulty scores often describe the SERP generally.
But SEO competition is not equally difficult for every website.
A finance publisher with hundreds of articles about credit cards may have a very different chance of ranking for “travel credit card rewards” than a general lifestyle blog publishing its first finance article.
This is why relative difficulty matters more than absolute difficulty.
Compare your site with the ranking domains.
Do you already rank for related topics?
Do you have supporting articles that can internally link to the new page?
Does your audience already associate your site with the subject?
Can you demonstrate relevant experience or expertise?
Google’s people-first content guidance encourages publishers to have an intended audience, maintain clear site focus, and demonstrate depth of knowledge or first-hand expertise where appropriate.
A keyword with a high general KD may still be achievable when your site has exceptional topical alignment.
Meanwhile, an “easy” keyword in a completely unrelated niche may be harder than expected.
Look Beyond Domain Authority and Count Page-Level Weaknesses
Seeing famous brands in a SERP can be intimidating.
But do not evaluate competition only by domain reputation.
Look at the ranking page.
A major website can rank with a mediocre article simply because it has authority. That does not mean its position is untouchable.
Review page-level weaknesses such as poor structure, outdated information, weak examples, missing comparisons, limited original analysis, confusing UX, or shallow explanations.
Also check whether the page itself has many referring domains.
A giant site might have thousands of backlinks at the domain level while the ranking URL has very few direct links.
That situation can sometimes be more approachable than the brand name initially suggests.
This is also why you should never automatically avoid SERPs containing large publishers.
Evaluate what you actually need to beat.
Sometimes the challenge is authority.
Sometimes it is content.
Sometimes it is both.
Keeping those problems seperate helps you estimate the real amount of work required.
Measure Content Quality Gaps
One of the best ways to estimate difficulty is asking a slightly uncomfortable question:
Can I genuinely create something better?
Not longer.
Better.
Google explicitly says its systems aim to prioritize helpful and reliable information, and its content guidance encourages original reporting, research, analysis, and substantial coverage.
Suppose every ranking article repeats the same five generic tips.
You may be able to differentiate through original testing, case studies, expert interviews, unique datasets, visual explanations, first-hand screenshots, or practical examples.
The opportunity becomes weaker when the SERP is already filled with excellent, current, deeply researched resources from highly relevant websites.
That is often harder than a backlink score alone suggests.
A useful manual rating is:
Weak content gap: You cannot clearly improve on existing results.
Moderate content gap: You can improve several sections or add stronger examples.
Strong content gap: Ranking content misses major parts of the user need.
The stronger the content gap, the lower the effective difficulty may be.
Factor in Freshness and Update Pressure
Some keywords require much more maintenance than others.
“History of Roman concrete” may remain relatively stable.
“Best AI writing tools” can change constantly.
That difference should affect how you evaluate difficulty.
A volatile SERP requires not only ranking effort but ongoing editorial performace.
New products appear. Pricing changes. Features disappear. Competitors update their pages repeatedly.
Even if you reach the top five, keeping that position could require regular updates.
Freshness therefore has two dimensions:
Can you outrank the current pages?
and:
Can you keep the page competitive afterward?
When evaluating dynamic topics, inspect publication dates, visible updates, product changes, and how frequently ranking pages appear to refresh.
Ahrefs specifically highlights outdated competing content as one type of SERP weakness that standard difficulty metrics may overlook.
But the reverse is also true: a SERP full of frequently updated expert pages may be more competetive than its KD number implies.
Do Not Ignore Page Experience and Technical Quality
Technical performance will not magically make weak content rank.
But poor page experience can still make competition harder than necessary.
Google states that its ranking systems look to reward content providing a good overall page experience and recommends considering factors such as Core Web Vitals, mobile usability, intrusive interstitials, distracting advertising, and clear access to the main content.
Imagine two pages provide similarly useful answers.
One loads smoothly, works well on mobile, and makes the information easy to access.
The other shifts constantly because of ads and covers most of the screen with pop-ups.
The first creates a stronger overall experience.
This does not mean you should chase perfect technical scores before targeting a keyword. Google itself notes that great Core Web Vitals alone do not guarantee top rankings.
Instead, include technical quality as one part of the competitive picture.
Create a Relative Difficulty Score for Your Own Site
Instead of relying entirely on third-party KD, build a simple internal model.
Rate each potential keyword from 1–5 across factors such as:
Backlink Competition + SERP Quality + Intent Complexity + Topical Gap + Content Effort + Authority Gap
Then add two positive factors:
Existing Relevance + SERP Weakness
For example, a keyword might have strong competing backlinks but poor content quality and excellent topical relevance to your site.
Another keyword could have fewer backlinks but near-perfect competing pages from specialist publishers.
The second opportunity may actually require more effort.
Semrush’s domain-specific PKD concept reflects a similar principle: ranking difficulty should account for the relationship between the keyword, your domain, and competing sites rather than treating difficulty as identical for everyone.
As your site grows, calibrate your model against real outcomes.
Track which keywords you ranked for, how long they took, how many links were required, and what content characteristics helped.
Your own historical data can eventually become more useful than any generic score.
Consider Business Value Before Deciding Whether Difficulty Matters
A difficult keyword is not automatically a bad keyword.
If ranking for it could generate substantial revenue, leads, subscribers, or strategic authority, the investment may be justified.
Likewise, an extremely easy keyword may not deserve resources when it has almost no traffic or business value.
Think in terms of:
Difficulty × Expected Reward
Suppose Keyword A requires three months of effort but could generate $3,000 in monthly revenue.
Keyword B may take only two weeks but produce $40 per month.
The harder keyword could still be the stronger business decision.
Ahrefs itself notes that difficulty should not automatically discourage publishers from pursuing strategically important queries; the metric can instead help estimate the resources required.
SEO difficulty is therefore not just about whether you can rank.
The better question is whether ranking is worth the required investment.
Evaluating keyword difficulty beyond traditional SEO metrics requires looking at the actual competitive environment rather than trusting one number.
Start with the KD score, but then inspect SERP quality, search intent, backlink strength, topical relevance, content gaps, freshness, page experience, and the authority difference between your site and current competitors.
Most importantly, make difficulty relative to your own website.
A keyword that looks impossible for one publisher may be realistic for another with strong topical depth and a clear content advantage.
Before rejecting your next high-KD keyword, manually review the ranking pages and identify what would actually be required to outperform them. Likewise, challenge every “easy” keyword before investing resources.
The best opportunities often appear where traditional metrics say “difficult,” but the SERP itself quietly reveals a weakness you are uniquely positioned to solve.
