How to read the numbers
Density is a ratio, so it moves when the text gets longer as well as when the keyword gets rarer. A 400-word service page with six mentions reads very differently from a 3,000-word guide with six. Check the count and the density together.
- Zero mentions: the page never says what it is about. Fix the introduction and one heading first.
- Under 0.5%: usually fine in a long guide that covers the topic through related terms. Worth a check that the title and first paragraph carry the keyword.
- 0.5% to 2.5%: where most ranking pages land.
- Above 4%: read the sentences aloud. The number is a symptom; repetitive phrasing is the problem.
The phrase tables matter more
Single-word counts confirm the topic. Repeated two and three word phrases show your habits: an opener you reuse every section, a qualifier you lean on, or the one variation of the keyword you accidentally wrote twenty times. Those are the fastest edits to make and the ones a reader notices.
What density does not tell you
Whether you covered the subject. A page can hit a perfect ratio and still miss the entities every ranking page mentions. For that comparison, the SEO content editor scores a draft against the pages that currently rank and lists what they include that you left out.
Frequently asked questions
What is a good keyword density?
A common range for pages that rank is 0.5% to 2.5% for the main keyword, which is roughly one mention every 40 to 200 words. Treat that as a sanity check, since there is no target ratio. Google has said for years that it does not reward a specific ratio, so the useful reading is whether a keyword appears often enough to be obviously the topic and rarely enough to read naturally.
Is keyword density still a ranking factor?
Not on its own. Search engines match pages on meaning and on the entities a page covers, so a page can rank without hitting any particular density. Density is still worth checking for the opposite reason: a very high number usually means repetitive writing, and a zero means the page never states its own subject.
Why does this tool count in my browser?
Because counting is arithmetic and language models are unreliable at it. Nothing you paste here is sent anywhere; the page tokenizes the text and counts it locally, so the numbers are exact and the text stays on your machine.
What do the two and three word phrases show?
The phrases you repeat without planning to. They are often more revealing than single words, because they surface filler you have leaned on and the variations of your topic that you used.
Should I remove a keyword if the density is high?
Read the sentences first. High density from a term the topic requires is fine. High density because every paragraph opens with the same phrase is a writing problem, and rewriting those openings fixes both the number and the reader's experience.
