Understanding the Score

What is Keyword Difficulty
in SEO?

Keyword difficulty is a metric that estimates how hard it would be to rank in the top 10 search results for a specific keyword. The keyword difficulty meaning is simple: a score from 0 to 100 that reflects competition level.

The score takes into account the authority of currently ranking pages, the number and quality of backlinks they have, and the overall competitiveness of the search results.

A keyword with a difficulty of 20 is something a new website could rank for within weeks. A keyword at 80+ typically requires a well-established domain with years of authority.

The Keyword Difficulty Scale: What is a Good Keyword Difficulty?

Understanding the keyword difficulty scale helps you set realistic expectations. What counts as a good keyword difficulty depends on your website's age, authority, and backlink profile.

Here is the scale we use, based on real ranking data:

0-14
Very Easy. New sites can rank with good content alone. These are your quick wins.
15-29
Easy. Achievable with quality content and basic on-page SEO. Ideal for new blogs building initial traffic.
30-49
Medium. Requires solid content and some backlinks. Sites with 6+ months of age and existing traffic can compete here.
50-69
Hard. Competitive territory. You need high-quality content, a strong backlink profile, and established domain authority.
70-100
Very Hard. Dominated by major brands and authoritative domains. Only attempt with a well-established site and a long-term strategy.

How is Keyword Difficulty Calculated?

Keyword difficulty is calculated by analyzing the top-ranking pages for a given search term. The primary factors include the number and quality of backlinks pointing to those pages, the domain authority of ranking sites, and the overall keyword competition score.

Backlink strength is the biggest factor. If the top 10 results all have hundreds of referring domains, it signals that you will need significant link-building effort to compete.

Our opportunity score goes a step further by combining difficulty with search volume. A keyword with 10,000 monthly searches and difficulty 25 has a much higher opportunity score than one with 100 searches and difficulty 15. This helps you find the best balance between effort and reward.

How to Find Low Competition Keywords

Finding low competition keywords is the fastest way to grow organic traffic, especially for newer websites. A low competition keyword typically has a difficulty score under 30 with decent search volume (100+ monthly searches).

Three approaches that work:

Start with long-tail keywords. Instead of targeting "email marketing," try "email marketing for dentists" or "email marketing automation for small business." Longer phrases have less competition and more specific intent.
Check the related keywords section. After analyzing your primary keyword, look at the related suggestions. Often you will find variations with significantly lower difficulty that still drive meaningful traffic.
Look for question-based keywords. Queries starting with "how to," "what is," and "why does" frequently have lower competition because they target informational intent rather than commercial.

Low Competition Keyword Checklist

Difficulty score under 30
Monthly search volume above 100
CPC indicates commercial value
Search trend is stable or rising
Related keywords offer cluster opportunities
Content type matches your strengths
Search intent is clear and actionable
You can create better content than current results

Common Mistakes When Choosing Keywords

Only looking at search volume. High volume means nothing if you cannot rank. A keyword with 50,000 monthly searches and a difficulty of 90 will bring you zero traffic if you are on page 5. A keyword with 500 searches and difficulty 15 can bring consistent, targeted visitors.

Ignoring search intent. A keyword like "best CRM software" has transactional intent. "What is CRM" is informational. Make sure your content type matches what searchers expect to find.

Targeting only easy keywords. While low-difficulty keywords are great for quick wins, building long-term authority requires gradually moving up to more competitive terms as your site grows.

Not considering keyword clusters. Instead of targeting individual keywords in isolation, group related terms together. One comprehensive article can rank for dozens of related keywords simultaneously.

Why Use a Free Keyword Difficulty Checker Tool?

Professional keyword difficulty tools like Ahrefs and SEMrush charge $129-$449/month for SEO keyword difficulty data. This free keyword difficulty checker tool gives you the same core metrics: difficulty score, search volume, CPC, trends, and related keywords, without a subscription.

Whether you are a small business owner planning your first blog posts, a content marketer building an editorial calendar, or an SEO agency evaluating opportunities for clients, this keyword difficulty checker tool gives you the data you need to make informed decisions. Check up to 10 keywords per hour, completely free.

Where Does This Data Come From?

This tool uses DataForSEO as its data source, the same API that powers many professional SEO platforms. Every check queries live data, not cached or estimated values.

Here is exactly what happens when you enter a keyword:

Keyword Overview API. Returns real search volume, keyword difficulty score (0-100), cost per click, and 12-month historical trend data. The difficulty score is based on the authority and backlink profiles of pages currently in the top 10.
Keyword Suggestions API. Returns up to 10 related keywords with their own volume and difficulty scores. These are semantically related terms that real users search for, not AI-generated guesses.
Opportunity Score. Calculated by our own formula: 40% weighted search volume + 60% inverse difficulty. This is proprietary to Ubenie and designed to surface keywords with the best effort-to-reward ratio.

Scores may differ slightly from Ahrefs, SEMrush, or Moz because each tool uses its own methodology and data sources. The underlying SERP data is the same. What varies is how each tool weights backlinks, domain authority, and content signals in their scoring formula.

FAQ

Common questions.

01

What is keyword difficulty?

[+]

A 0-100 score estimating how hard it is to rank in the top 10 results for a keyword. It is calculated from the authority and backlink profiles of pages currently ranking. Higher numbers mean more competition.

02

How is keyword difficulty calculated?

[+]

Keyword difficulty is calculated by analyzing the top-ranking pages for a search term. The primary factors are the number and quality of backlinks pointing to those pages and the domain authority of ranking sites. Each tool uses its own formula, which is why scores differ between Ahrefs, SEMrush, and Moz. The underlying SERP data is the same. What varies is how each tool weights backlinks, domain authority, and content signals.

03

Is lower keyword difficulty always better?

[+]

Lower difficulty means easier to rank, but it is not always better. A keyword with difficulty 5 and 10 searches per month is easy but worthless. The best targets combine low difficulty with meaningful search volume. That is what the opportunity score measures: it weights volume at 40% and inverse difficulty at 60% to surface keywords with the best effort-to-reward ratio.

04

What difficulty should I target?

[+]

New websites should target keywords under 30. Sites with some authority can go up to 50. Only established sites with strong backlink profiles should attempt keywords above 70. Start with easy wins and move up as your domain authority grows.

05

How to find low competition keywords for free?

[+]

Enter a broad keyword into this tool and look at the related keywords table. Long-tail variations often have a fraction of the difficulty. Question-based keywords (how to, what is) also tend to have lower competition. Another approach: check what ranks on page 1 for your keyword. If you see forums, small blogs, or low-authority sites, competition is low.

06

Can I use ChatGPT for keyword research?

[+]

ChatGPT can brainstorm topic ideas and suggest keyword variations, but it has no access to real search data. It cannot tell you actual search volume, keyword difficulty, or what your competitors rank for. Use ChatGPT for ideation, then validate every keyword with a tool that uses live SERP data before committing to content creation.

07

Why do difficulty scores differ between SEO tools?

[+]

Each tool uses its own methodology. Ahrefs weights referring domains heavily. SEMrush factors in domain authority and content relevance. Moz uses its own Page Authority metric. The raw SERP data is similar, but the scoring formulas differ. A keyword at 30 in Ahrefs might be 45 in SEMrush. What matters is consistency within one tool, not comparing numbers across tools.

08

Where does this tool get its data?

[+]

This tool uses DataForSEO, the same API that powers many professional SEO platforms. Every check queries live data for difficulty scores, search volume, CPC, 12-month trends, and related keywords. The opportunity score is our own formula combining volume and inverse difficulty.

09

How accurate is this tool?

[+]

It uses real-time data from industry-leading SEO databases. No tool can predict rankings with 100% certainty since Google uses 200+ ranking factors, but difficulty scores provide reliable guidance for content strategy. The data is as accurate as what professional tools like Ahrefs or SEMrush provide.

10

Is this really free?

[+]

Yes. You can check up to 10 keywords per hour with no account required. No email gate, no feature restrictions. The data you get for free is the same quality a paid tool provides.
