Keyword Density Checker Online Free (Text or URL)
Table of contents
Keyword density is how often a word or phrase appears in a text, as a percentage of total words. It is worth being straight about what that number is worth today: as a ranking factor it is largely obsolete. Search engines in the 1990s counted keywords, people gamed it by repeating them, and engines responded by building far better ways to understand meaning. Modern systems recognise synonyms, related concepts and intent, so an article about "car insurance" ranks perfectly well while also using "vehicle cover" and "policy". There is no target percentage to hit, and no tool can give you one honestly. What density analysis is still genuinely useful for is diagnosis. It shows what a page is actually about, which is often not what you assumed. It catches accidental repetition that makes writing tedious. It reveals when a competitor's page covers terms yours never mentions. Use it as a mirror on your own text, not as a target to optimise towards. This tool analyses pasted text or fetches a live URL, and counts both single words and multi-word phrases.
Key benefits
- Shows what a page is actually about, which frequently differs from the intention.
- Counts multi-word phrases, matching real search behaviour rather than isolated terms.
- Works on a live URL, so you can analyse a competitor page as easily as your own draft.
- Catches unintentional repetition that makes prose tiring to read.
- No account needed, and pasted text is analysed without being stored.
How to use it, step by step
- Choose text or URL. Paste your draft directly, or enter a live page address to analyse what is published.
- Run the analysis. Word and phrase frequencies are counted, with common filler words handled separately so they do not dominate the list.
- Read the top terms. Ask whether they describe what the page is really about. If the main topic is not near the top, that is the finding.
- Check the phrases, not just the words. Two and three-word phrases match how people actually search far better than single words do.
Common use cases
- Checking a draft before publishing to confirm it reads naturally rather than repetitively.
- Seeing which terms a competing page emphasises that yours never mentions.
- Auditing an old page that has stopped ranking, to see whether its focus drifted.
- Reviewing content written by someone else against the brief it was written for.
- Spotting keyword stuffing in inherited content before it becomes a liability.
Pro tips
- Do not write to a percentage. If you are adding a keyword to move a number, you are making the page worse.
- Look at what is missing rather than what is frequent. Absent related terms are more informative than the top of the list.
- Focus on two and three-word phrases, which reflect real queries far better than single words.
- Check the terms in your headings separately - those carry more weight than an equivalent mention in body text.
- Compare against a page that already ranks well for your topic, and treat the gaps as questions rather than a checklist.
Common mistakes to avoid
- Chasing an "ideal" density figure such as 2%. No such target exists; sources quoting one are repeating 2005-era advice.
- Adding keyword repetitions to hit a number, which reads badly to humans and is exactly what stuffing detection looks for.
- Ignoring synonyms and related terms, which modern search engines weigh heavily.
- Analysing an entire page including navigation and footer, then wondering why site-wide terms dominate.
- Treating a single-word list as the whole picture when almost all real queries are phrases.
Frequently asked questions
How do I check keyword density?
Paste your text or enter a URL above and run the analysis. You get frequency and density for both single words and multi-word phrases, so you can see what the page emphasises.
Is there an ideal keyword density I should aim for?
No. There is no target percentage that improves rankings, and any figure quoted as ideal is outdated advice. Write naturally for a reader and use density to check the result, not to steer it.
Does keyword density still matter for SEO in 2026?
Not as a ranking factor. Search engines understand topics, synonyms and intent rather than counting repetitions. Density remains useful as a diagnostic - it tells you what your page is actually about - but optimising towards a number has no upside and real downside.
What is keyword stuffing and how do I avoid it?
Repeating a term unnaturally to influence rankings. The reliable test is simply reading the text aloud: if a phrase appears where a normal writer would use a pronoun or a synonym, it is stuffed.
Can I analyse a live URL or only pasted text?
Both. Text mode analyses a draft before publishing; URL mode fetches a published page, which is also how you inspect a competitor.
Does it check multi-word phrases?
Yes, and those matter more than single words. Almost all real searches are phrases, so two and three-word counts are the more useful part of the report.
