Keywords appearing in the first 10% of content carry more weight for SEO.
The Keyword Density Analyser breaks any piece of writing down into its most frequent words and phrases, then shows exactly how often each one appears and what percentage of the total text it represents — so you can optimise content for search engines without overdoing it.
Keyword density is the share of your total word count that a given term takes up, expressed as a percentage. Search engines once leaned heavily on this signal, and while modern ranking is far more sophisticated, density is still a useful proxy for how focused a page is on its topic. This tool tokenises your text, filters out common stop words like "the" and "and" so the noise disappears, and then ranks the keywords that actually matter. It goes beyond single words: it surfaces the most repeated two-word bigrams and three-word trigrams, because real search queries are usually phrases rather than isolated terms. It also scores keyword prominence — terms that appear early in your content carry more weight — and flags SEO signals such as thin content or any keyword that has crept above a safe density.

Keyword density is the percentage of your total word count that a particular word or phrase makes up. If a 1,000-word article uses the term "running shoes" ten times, its density is 1%. It is a rough measure of how strongly a page focuses on a given topic.
Most SEO practitioners recommend 0.5–2.5%. Below that, the term may not look relevant; above 3–4%, you risk being flagged for keyword stuffing.
There is no single magic number, and modern search engines do not use a fixed threshold. As a practical guide, keep your main keyword around 1–2% and let it read naturally. Writing for clarity and intent matters far more than hitting an exact percentage.
Yes. Repeating a keyword unnaturally — known as keyword stuffing — can trigger search-engine penalties and makes copy awkward to read. When density climbs above about 3–4%, treat it as a warning sign and rewrite to use synonyms and natural variations instead.
Usually phrases. Real searches are mostly multi-word queries, so the bigrams and trigrams this tool surfaces often match search intent better than single words. Use single-word density to gauge topical focus, and use phrases to target the longer queries people actually type.
Yes — common function words like "the", "and", "of" are filtered out so the table shows the keywords that actually matter for SEO.
