Check how competitive any keyword is and estimate how hard it will be to reach page one of Google search results.

Keyword difficulty ranges.

What each score range means and whether you can realistically rank for it.

0-10

Very easy

Brand new sites with a well-optimized page and no backlinks needed.

11-20

Easy

New sites that have published consistently for 3+ months.

21-40

Medium

Established sites (DR 20-40) with focused topical content.

41-60

Hard

Authoritative sites (DR 40-60) with solid internal linking.

61-80

Very hard

High-DR sites with dedicated link-building campaigns.

81-100

Extreme

Wikipedia, Amazon, and top-20 global domains only.

What is keyword difficulty?

Keyword difficulty (KD) is the single most useful filter in modern keyword research. It compresses everything you would otherwise check manually - how many backlinks top pages have, how authoritative the ranking domains are, how much content depth the SERP expects - into a single 0-100 score. Lower scores mean weaker competitors and faster ranking potential; higher scores mean more work, more links, and more time before you see position gains.

KD is derived from the top 10 search results for a keyword, not the keyword itself. That is why the same keyword can have very different scores across countries: different SERPs mean different competitors. Always check KD in the location where you actually want to rank, not the default US SERP. This tool supports 13 major locations so you can model your target market accurately.

Filter by difficulty first

Before writing a single word, sort your keyword list by KD and focus on the lowest-hanging fruit with decent volume. A KD 15 keyword with 500 searches is almost always a better bet than a KD 50 keyword with 5,000.

Match KD to your domain rating

A new site should aim 20+ points below its domain rating. Pick KD 0-20 if your DR is still low; move up the difficulty ladder as you publish and earn links.

Do not chase KD 0 blindly

Many KD 0 keywords have no search volume or poor intent. Cross-reference KD with monthly searches and commercial intent before targeting.

Track KD over time

A KD that drops is a signal - a competitor lost backlinks, a top result fell, or SERP volatility opened a window. Rerun your target list monthly to catch these moments.

Frequently asked questions.

What is keyword difficulty?

Keyword difficulty is a 0-100 score estimating how hard it is to rank in Google's top 10 for a given keyword. It is calculated from the strength of the pages already ranking - their backlinks, domain authority, and topical depth. A low score means weaker competitors you can realistically outrank with a well-written page. A high score means entrenched sites you would need substantial link authority to beat.

How is the difficulty score calculated?

The score uses the same signals Ahrefs and Semrush use: the average referring domains of the top 10 results, the distribution of domain ratings, and how competitive the SERP features are. A score of 30 means an average new site can realistically compete; 70 means only authoritative domains have a shot.

What difficulty range should I target?

New sites (domain rating under 20) should target KD 0-20 keywords to build initial rankings. Established sites (DR 20-50) can compete for KD 20-40. Only authoritative domains (DR 50+) should routinely go after KD 40+ without extensive link building. The fastest ROI usually comes from keywords in the 10-30 range with decent search volume.

Why do I get 'No data' for some keywords?

We return no difficulty for keywords with too little search data - typically brand-new terms, very long-tail queries, or misspellings. If you get no data, the keyword likely has under 10 searches per month, which is usually too low to be worth optimizing for in the first place.

How often does the difficulty score update?

Difficulty scores refresh monthly based on fresh SERP snapshots. Your score reflects the competitive landscape from the last refresh. Because the top 10 for most keywords is relatively stable month-to-month, small changes in difficulty (±3 points) are normal and do not warrant action. Jumps of 10+ points usually mean a competitor has moved in or out of the top 10.

Is this tool free?

Yes. You get 5 free lookups per day (up to 20 keywords per lookup). Identical keyword sets are cached for 24 hours and do not consume your quota.
