About Keyword Density Checker
A keyword density checker helps when you're editing a landing page and want to confirm the main phrase actually appears, when an article reads as repetitive, or when you're comparing your page with a competitor's. Use Analyze a web page for a live URL, or Paste text for a draft that isn't online yet. Type the phrase the page should rank for in Focus keyword and you get a checklist: how many times it's used, its density against the usual 0.5% to 3%, and whether it appears in the opening text, the title, the meta description, the H1, an H2 or H3 subheading, the page address and a picture's alt text. Every place it's missing comes with a tip. Show where it appears lists the sentences that contain it, with the keyword highlighted, for up to 8 places. Pasted text has no title or headings, so there the checklist covers the count, the density and the opening text.
For a URL, our server fetches the page's visible text, title, description, headings and alt text, and the counting happens in your browser. Pasted text never leaves your device. Words are split with your browser's own word segmenter, so Chinese is counted in words rather than single characters. You get three tables, single words, two-word phrases and three-word phrases, each with a count and a density percentage, and for a page, whether each keyword appears in the title, description and H1. Common words and numbers are ignored by default, and you can set the shortest word length. When one word makes up more than 5% of the text, you get a keyword stuffing warning. Each table exports as CSV, and Download JSON saves the results together with the focus keyword checklist. For the other on-page basics, from title length to headings and alt text, run the SEO Checker.
