Where the score comes from
Keyword difficulty looks at the pages currently on the first page for a keyword and estimates how strong they are — mostly how many other sites link to them, and how established the domains are. The stronger the current top 10, the higher the score.
How to read the number
- Under 30 — easy. Winnable for a small or new site, if the page itself is genuinely good.
- 30–50 — moderate. Doable with a strong page and some patience.
- 50–70 — hard. Expect months of work, and you'll likely need other sites linking to you.
- Over 70 — very hard. The first page is dominated by big brands. A new site targeting these is usually wasting its effort.
Why specific keywords win
Longer, more specific keywords almost always carry a lower difficulty. "Invoicing" might score in the 80s while "invoicing software for freelancers" sits in the 20s. The specific keyword has less search volume, but the people searching it know exactly what they want — a smaller number of visitors who are far more likely to become customers beats a ranking you'll never get.
Caveats worth knowing
Every tool calculates its own difficulty score, so the same keyword can be a 25 in one tool and a 45 in another. Treat the number as relative: use it to compare keywords against each other, not as an absolute promise. And difficulty says nothing about whether the keyword is worth ranking for — a score of 5 doesn't help if nobody searching it wants what you sell. Check the intent first.
