About the Keyword Density Checker
The Keyword Density Checker analyses any block of content and shows you how often each word and phrase appears, both as a raw count and as a percentage of total words. Use it to make sure your target terms are represented naturally and to spot signs of keyword stuffing.
What it does
Paste your content or a URL and the tool tokenises the text, strips stop words, and lists the most common one, two and three-word phrases. Each phrase is shown with its count and its density percentage, so you can compare against your target keywords.
Why it matters
Modern search engines are far smarter than the old keyword-density thresholds of the 2000s, but coverage still matters. If your page targets a keyword that only appears once, Google may not classify it correctly. If it appears in every second sentence, you risk being flagged as spammy.
How to use it
- Paste your content directly, or enter a URL to fetch it.
- Choose whether to include one, two or three-word phrases.
- Review the top phrases and check that your target keyword is present.
- Rewrite sentences that repeat the same keyword unnaturally.
- Re-check to confirm density sits in a natural range for your topic.
Best-practice tips
- Aim for your primary keyword to appear a few times across the intro, body and conclusion.
- Use synonyms and related phrases (semantic SEO) rather than the same exact match everywhere.
- Include your target keyword in the H1, first paragraph, one H2 and the meta description.
- Do not force keywords into anchor text; use varied, descriptive phrases.
- Write for the reader first, then adjust for keywords, not the other way around.
Frequently asked questions
What is an ideal keyword density?
There is no fixed number, but 0.5 to 2 percent for your primary keyword is a safe range for most content. Focus on natural language and topical coverage, not a magic figure.
Does keyword density still matter in 2026?
Google no longer uses raw density as a ranking factor, but keyword presence and topical coverage do matter. This tool helps you confirm you have covered a topic properly.
Can high keyword density hurt my rankings?
Yes. Repeating a keyword unnaturally can trigger spam signals and reduce readability, which hurts both rankings and user engagement.
