Keyword Difficulty, Explained in 5 Minutes
Keyword difficulty is a 0–100 estimate of how hard it is to reach page one. What the score means, why tools disagree and how to use it well.
Key takeaways
- Keyword difficulty (KD) estimates how hard it is to reach Google's first page for a search, usually on a 0–100 scale.
- It's a third-party estimate, not a Google metric. Each tool calculates it differently, so compare scores within one tool only.
- Use it to sort, not to decide: intent and how close you already rank matter more.
- Newer sites should start in the lowest third of the scale and move up as they earn trust.
Keyword difficulty (KD) is an estimate of how hard it would be to get a page onto Google's first page for a given search. Most SEO tools show it as a number from 0 (easy) to 100 (very hard). It's useful for sorting a list of searches, but it's an estimate made by the tool, not a number from Google.
How keyword difficulty is calculated
Each tool has its own formula, but the idea is the same: look at the pages already ranking on page one, measure how strong they are, and turn that into a score. Strength usually means things like how many other sites link to those pages, and how established their sites are.
That's why a search full of big brands and well-linked guides scores high, and a specific local search where page one is thin scores low.
Why tools disagree
Because each tool uses its own data and formula, the same search can score 18 in one tool and 30 in another. Neither is wrong; they're different rulers. Two practical consequences:
- Compare scores within one tool only. A 20 in one tool isn't a 20 in another.
- Don't treat the boundaries as exact. There's no real difference between a 24 and a 26.
How to use the score
| Score (on a 0–100 scale) | What it usually means | Good for |
|---|---|---|
| 0–20 | Thin competition on page one | New and small sites, supporting articles |
| 21–40 | Some strong pages, room to compete | Sites with a few clusters live |
| 41–70 | Established competitors | Sites with real authority on the topic |
| 71–100 | Dominated by big brands | Long-term targets, not starting points |
These bands are rough guides, not rules. The point is to start where you can win, rank there, and let those wins earn the links and trust that make harder searches reachable.
What difficulty doesn't tell you
- Intent. A difficulty 5 search is worthless if the people typing it don't want what you sell. Check intent first, as we cover in how to find keywords you can actually win.
- Where you already stand. If you already rank #12 for a "hard" search, it may be easier for you than a "low" one you've never appeared for. Search Console shows this.
- How good your page will be. Difficulty measures the competition, not your answer. A page that answers the question more directly can beat stronger pages, which is also why mass-produced AI pages rarely do.
Difficulty, volume and intent together
Difficulty is one of three numbers worth looking at, and it's never the deciding one on its own. Here's how the same four searches compare once you look at all three for a small coffee catering business:
| Search | Volume | Difficulty | Intent | Verdict |
|---|---|---|---|---|
| coffee catering for events | 880 | 9 | Hire a caterer | Win it first: easy and close to the offer |
| wedding coffee bar | 1,300 | 19 | Plan a wedding | Next: a bit harder, still buyers |
| how to brew pour over | 9,900 | 56 | Learn at home | Skip: hard, and nobody's hiring |
| specialty coffee beans online | 3,100 | 41 | Buy beans | Skip unless you sell beans online |
The numbers are illustrative. The pattern isn't: the best first targets combine low difficulty with intent that matches what you sell, even when the volume is modest.
Read page one yourself in two minutes
Before trusting any score, look at the actual results. Search the keyword in a private window and ask:
- Who's ranking? Big national brands and marketplaces, or small sites like yours?
- What kind of pages? If page one is all product pages and you're planning an article, the intent doesn't match.
- How good are they? Outdated dates, thin answers or forum threads on page one are openings.
- Is there an AI answer or a big answer box on top? If the full answer is already shown, fewer people click through. (Being the source that answer cites is a different game: see how to show up in AI answers.)
- Would your page be the best one here? If you can't say yes, pick another search.
When a "hard" keyword is worth it
Sometimes a difficult search is still the right target:
- It's exactly what you sell, and every click is a likely customer.
- You already rank on page two for it, so you're closer than the score suggests.
- It's the pillar of a cluster whose easier supporting articles are already ranking and linking to it.
In those cases, treat it as a long-term goal: publish the easier articles first, link them to the pillar, and give the cluster a few months to build up.
Difficulty inside a topic cluster
Inside a topic cluster, difficulty helps you split the work. The broadest search you can realistically win becomes the pillar. The easier, more specific searches become supporting articles, and they tend to rank first, which helps the pillar through the internal links between them.

FAQ
What is a good keyword difficulty score?
+
For a new or small site, anything in the lowest third of your tool's scale is a good place to start. Established sites with strong links can aim higher.
Does Google use keyword difficulty?
+
No. Keyword difficulty is calculated by SEO tools to estimate competition. Google doesn't publish a difficulty score.
Why do two tools give different difficulty for the same keyword?
+
They use different data and formulas. Some weigh the links pointing to the pages on page one, others mix in other signals. Treat each tool's scale as its own.
