Keyword Density Checker

Enter a URL — and optionally a focus keyword — and we extract the visible copy, strip navigation and scripts, and report what the page is actually about.

What “good” density looks like

There is no target number, and any tool that gives you one is selling certainty it does not have. As a sanity range, a focus keyword appearing in roughly 0.5%–2.5% of words reads naturally in most copy. Below that, the page may not clearly signal its subject. Above about 3.5%, it usually reads badly — and badly written copy underperforms regardless of what any formula says.

Placement beats frequency

Where the term appears matters far more than how often. Aim for the title tag, the H1, the first hundred words, at least one subheading, the URL slug where sensible, and image alt text where it is genuinely descriptive. Hitting those once each is worth more than twenty repetitions in body copy.

Use the phrase lists for entity coverage

The two and three-word lists show which concepts the page actually covers. Compare them against the pages currently ranking for your term: if the top results all discuss subtopics that never appear in your list, that is your content gap — and it is usually a bigger problem than density.

Signs of over-optimisation

• The same exact-match phrase repeated in several consecutive headings.
• Awkward grammar caused by forcing a keyword into a sentence.
• City or product name variants stacked in a list at the bottom of the page.
• Density above 4% on a page under 500 words.

None of these earn a manual penalty on their own, but they all reduce quality — and quality is what the algorithm is trying to approximate.

Write for the query, then check

The productive order is: understand the intent, write the best answer, then run this tool to confirm the page reads as being about the subject and is not stuffed. Using it the other way round — writing to hit a density figure — produces pages that rank worse and convert worse.
