What Is Keyword Difficulty in SEO? (And How to Judge It Yourself)
What difficulty scores mean, their limits, and a simple way to assess competition by hand.
Keyword difficulty is an estimate of how hard it would be to rank on the first page for a search. Most SEO tools show it as a score from 0 to 100. It is useful as a rough filter โ but every tool calculates it differently, and none of them know your site as well as you do.
What difficulty scores usually measure
Most tools base difficulty mainly on the backlinks of the pages currently ranking โ how many links and how strong. Some add content, domain strength or search features. That means scores mostly tell you how many links the competition has, not how good their content is.
Why scores disagree
- Different link databases and formulas.
- Different data on which pages rank (rankings change by country and device).
- Different update frequencies.
A keyword can be "easy" in one tool and "hard" in another. Use one tool consistently to compare keywords against each other.
Judge difficulty yourself
Search the keyword in the country you target and look at the top ten:
- Who ranks? Big brands and government sites everywhere means hard. Forums, small blogs and thin pages mean there is an opening.
- How well do they answer? Outdated, incomplete or off-topic results are beatable.
- Does intent match your page type? If results are all product pages and you have a guide, it is harder.
- Search features: many ads, maps or AI answers above results reduce clicks.
What is a good difficulty for a new site?
For new or small sites, focus on keywords where top results include weaker sites and where you can write a clearly better answer โ often specific long-tail searches. Read how to find low-competition keywords and how to rank a new website.
Balance difficulty with value
An easy keyword nobody searches for is worthless; a hard keyword with huge value may be worth a long-term effort. Score keywords on three things: difficulty, search demand and business value. Find and compare ideas with the keyword research tool.
A worked example
A new Australian accounting software start-up targeted "accounting software" (very hard) and saw no progress. It switched to specific searches such as "how to do bookkeeping for a small cafรฉ", where the top results were general articles and forum threads. It wrote detailed, practical guides with templates, and within months several reached the first page, bringing trial sign-ups while it worked toward harder terms.
A simple scoring method
Rate each keyword from 1 to 3 on demand, business value and your chance of ranking after checking the results. Add the scores and start with the highest totals โ not simply the lowest difficulty. Revisit the scores every few months as your site grows stronger.
