A keyword density checker measures how often a keyword or phrase appears in your content relative to the total word count. It's one of the quickest on-page SEO checks you can run — a guardrail that confirms your target keyword actually shows up, without being repeated so often that it reads unnaturally.
Modern search engines like Google reward content written for people, not for algorithms. Density isn't a ranking dial you turn up — it's a sanity check. After tuning your density, add schema markup and confirm your AI Overview readiness to round out your on-page SEO.
Single-word counts only tell part of the story. This keyword phrase density checker also analyzes 2-word and 3-word phrases, because most real search queries are long-tail phrases. Paste a draft, check that your focus keyword lands in the healthy 0.5%–2.5% range, and scan the phrase tabs for any combinations you're leaning on too hard.
If a keyword is over-used, replace some instances with synonyms or restructure sentences so the meaning stays but the repetition drops. If it's under-used, work it into a heading, the intro, or an image alt text naturally. Pair density checks with a strong meta title and description, and make sure new pages are discoverable with a fresh XML sitemap.
Each tool in our free suite covers a different SEO layer — use them together for a complete on-page workflow.
Everything you need to know about checking keyword density online, healthy ranges, and avoiding keyword stuffing.
