Measure keyword frequency and avoid stuffing with exact density percentages. See which terms dominate your content and optimize naturally — no signup required.
Paste content and enter a primary keyword to see density analysis.
Writing for a keyword makes you repeat it. You start deliberately, then it creeps in — subheadings, image alt text, the conclusion — and by the time you finish, the page reads like it was written for a machine. Which is exactly the impression you were trying to avoid.
This checker gives you the number. Paste your content, enter your keyword, and see precisely how often it appears and what percentage of the text it represents.
Page content — paste the whole thing, with a live word count as you go.
Primary keyword, and optionally secondary keywords as a comma-separated list.
There is also a toggle to strip common words from the frequency table, which is what makes that table useful. Without it, your top results are "the," "and," and "to." With it, you see the terms that actually characterise your content.
There is no magic number, and anyone quoting one precisely is inventing it.
The useful framing is a range rather than a target. Roughly 1–2% usually reads naturally for a primary keyword. Push past 3–4% and it starts to sound repetitive to a reader — which is the real problem, because the reader notices before any algorithm does.
Too low matters too. If a 2,000-word article mentions its topic twice, the page is unclear about what it covers.
The reliable test: read it aloud. If you notice the keyword, it is too dense. The number simply confirms what your ear already told you.
Most people come for the density percentage and get more value from the frequency list.
It shows which words genuinely dominate your content — and that is often not the keyword you intended. An article meant to be about "email automation" that mentions "software" thirty times and "email automation" four times is about software, whatever the title says.
That mismatch between intended topic and actual language is a common reason pages underperform, and it is invisible until you count.
Modern search understands related terms, so a page covering a topic properly uses the vocabulary that surrounds it — not the same phrase repeated.
Enter your secondary keywords and check whether they appear at all. A page about email marketing that never mentions open rates, subject lines, or deliverability is thin regardless of how often it says "email marketing."
Adding the missing related terms is almost always more valuable than adjusting the density of the main one.
An SEO auditor inherits a client's service page that ranks poorly despite obvious effort. Reading it, something feels off but the specific problem is hard to name.
She pastes it in. Primary keyword density is above 5% — the phrase appears in every subheading, the opening sentence of most paragraphs, and twice in the conclusion.
She rewrites, replacing most instances with natural pronouns and related terms, and adds three secondary keywords the page never mentioned. Density drops to a comfortable level and the page reads like a person wrote it for another person.
Content writers checking a draft before publishing. SEO auditors diagnosing pages that read as spammy. Bloggers who write to a keyword and want a sanity check. Anyone who has re-read their own article and winced. Pair it with the Keyword Generator for related terms and the Content Gap Checker for topics you have missed. Our web development team builds on-page SEO into sites from the start.
You already suspect you overused it. Paste the article above, see the actual number, and fix it before it goes live rather than after someone tells you it reads badly.
