Free SEO Tool

Free Keyword Difficulty Checker

Get a difficulty score out of 100, plus the pages you would actually have to outrank and the SERP features taking clicks before anyone reaches them. No sign-up.

How to check keyword difficulty

Three steps, and the third is the one other tools skip:

1. Enter a keyword

Any search term you are considering targeting. No account, no credits, and no domain needed.

2. Pick a country

Difficulty is not the same everywhere. A keyword can be crowded in the US and wide open elsewhere.

3. See the score and the reason

A difficulty score out of 100, and underneath it the pages currently ranking and the features taking clicks before they get there.

What is keyword difficulty?

Keyword difficulty, often shortened to KD, is a 0 to 100 estimate of how hard it would be to reach page one for a term. It is calculated from the strength of the pages already ranking, principally their backlink profiles.

Two things are worth understanding about it. It is relative to your site, so a score of 40 is routine for an established domain and out of reach for a new one. And it is an estimate from one index: every tool computes KD differently, so scores are comparable within a tool and not across them.

This is also why a number on its own is not much help. A score of 45 could mean ten authority sites you will never displace, or ten thin forum threads you could beat this month. Those need different decisions, which is why this page shows you the results themselves.

How to read a keyword difficulty score

Five bands, all of which mean something different depending on the site asking:

0 to 14

Very easy

Little established competition. A genuinely useful page can rank without strong links.

15 to 29

Easy

Reachable for most sites with focused content. The band worth hunting when starting out.

30 to 49

Moderate

Competitive but open. Expect to need better content than what ranks, plus some links.

50 to 69

Hard

Established sites hold these spots. Realistic with real authority behind the page.

70 to 100

Very hard

Dominated by strong domains. Target long-tail variants instead unless you already compete there.

Difficulty is not the same as competition

These four numbers appear side by side in most keyword tools and are routinely confused. Two are SEO metrics and two come from the ad auction:

Metric	What it measures	Where it comes from	Use it for
Keyword difficulty	How hard it is to rank organically	Strength of the pages currently in the top 10	Deciding what content to write
Ads competition	How many advertisers bid on the term	Google Ads auction data	Judging commercial intent, not SEO effort
Search volume	How many people search it monthly	Google Ads estimates	Sizing the opportunity
CPC	What advertisers pay per click	Google Ads auction data	Gauging how valuable the traffic is

A keyword can carry high ads competition and low SEO difficulty, or the reverse. This page reports both so the difference is visible. For volume, CPC and a twelve month trend across several keywords at once, use our keyword search volume checker.

Why the score alone is not enough

Every difficulty tool gives you a number. Almost none show you what produced it, and that omission hides two things that change the decision:

1Who actually ranks. Ten government and encyclopedia pages at KD 45 is a harder target than three small blogs at KD 55. The number cannot tell those apart.
2What sits above the results. An AI Overview, a featured snippet and four paid slots push position one a long way down. A keyword can be easy to rank for and still send very little traffic.

So this checker lists the competing pages and flags the features taking clicks. For the full results page including People Also Ask questions, use our SERP checker, and to turn a hard keyword into reachable ones, the long tail keyword generator is the next step.

How to find low difficulty keywords

Six habits that surface winnable keywords faster than filtering on a score:

Add qualifiers. A long-tail variant of a hard keyword is usually a fraction of the difficulty and converts better.
Check the SERP, not just the score. Ten forum posts at KD 45 is a softer target than three authority sites at KD 35.
Look for outdated results. A top 10 full of pages from several years ago is an opening regardless of the number.
Prefer question keywords. They tend to be lower difficulty and map neatly onto a section of an article.
Discount keywords where an AI Overview and four ads sit above position one, whatever the difficulty says.
Judge difficulty against your own site. A score of 40 means different things for a new domain and an established one.

Where this fits in keyword research

Difficulty is one input among several, and checking it first saves writing pages that were never going to rank:

1. Size the demand

Check search volume and CPC to see whether the keyword is worth anything before asking how hard it is.

2. Check the difficulty

Score plus the pages ranking. This is where a keyword either stays on the list or comes off it.

3. Write something better

A winnable keyword is only an opportunity until a page exists that deserves the position.

Frequently asked questions

What is a keyword difficulty?

Keyword difficulty estimates how hard it would be to rank on page one for a term, on a scale of 0 to 100. It is derived from the strength of the pages already ranking, principally their backlink profiles. It is an estimate of competition, not a measure of how valuable the keyword is.

What does KD mean in SEO?

KD is simply the abbreviation for keyword difficulty. You will see it in most SEO tools as a 0 to 100 number next to a keyword. Because each tool calculates it from its own index and formula, KD 40 in one tool is not necessarily KD 40 in another, so compare within a tool rather than across them.

How to check keyword difficulty?

Enter the keyword in the checker above and pick your market. You get the difficulty score along with the pages currently ranking and the SERP features sitting above them. Doing it by hand means searching the term and assessing the top ten yourself, which is the same judgement a score is trying to automate.

What is a good keyword difficulty score?

There is no universal answer, because difficulty is relative to your site. For a new domain, keywords under about 30 are the realistic targets. For an established site with a strong backlink profile, 50 is routine. The more useful question is not whether a score is good but whether it is beatable by you.

How to find low difficulty keywords?

Add qualifiers to broad terms, since long-tail variants are almost always easier and usually convert better. Favour question keywords, look for SERPs where the top results are old or thin, and check the results page rather than trusting the score alone. Our long tail keyword generator is built for exactly this step.

What is a good tool to check the difficulty of a keyword?

The practical tests are whether it makes you sign up, whether it shows the reasoning behind the number, and whether it accounts for SERP features. This one is free with no account and shows the competing pages and the features above them, because a score on its own tells you a keyword is hard without telling you why.

What does keyword difficulty score indicate in Semrush?

The same underlying idea, estimated ranking difficulty on a 0 to 100 scale, calculated from Semrush's own index and formula. Every provider weights the inputs differently, so treat scores from different tools as separate scales rather than interchangeable numbers.

Should I only target low difficulty keywords?

Not exclusively. Low difficulty keywords are where a newer site should start, because they are the ones it can actually win, but a strategy made only of them caps out quickly since they tend to carry less volume and weaker intent. The workable approach is to earn rankings on reachable terms first, and let the authority that builds make the harder ones realistic later.

What are the three types of keywords?

Most commonly they are grouped by intent: informational, where someone wants to learn; navigational, where they want a specific site; and transactional, where they want to buy or act. Difficulty tends to rise with commercial intent, since more sites compete for terms that make money.

What are the four types of keywords?

The four-way split adds commercial investigation to the three above, covering research before a purchase, such as comparisons and best-of searches. Those often carry high difficulty and high CPC together, which is a signal the traffic is valuable rather than a reason to avoid it.

Is keyword difficulty the same as competition?

No, and confusing the two is common. Keyword difficulty estimates organic ranking difficulty from the pages in the top ten. The competition figure shown by keyword tools usually comes from Google Ads and reflects how many advertisers bid on the term. A keyword can have high ads competition and low SEO difficulty, or the reverse.

Is there a free tool that can check my keyword ranking, or keyword density?

Yes to both, and they are different jobs from this page. Our keyword rank checker reports where a domain sits for a term, and our keyword density checker analyses how often a term appears in a piece of content. Neither tells you how hard a keyword is to rank for, which is what this tool is for.

Why does the difficulty score sometimes show no data?

Because there is genuinely no score available, usually for keywords with very little search data behind them. We report that as no score rather than showing zero, since no data and effortless are very different answers and collapsing them would be misleading.

Is this keyword difficulty checker free?

Yes. Several free checks per day, no account, no credits and no trial. The full result is shown every time, including the competing pages, which several well-known difficulty tools put behind a login.
