Keyword Density Checker

Worked example

Example 1: a 800-word guide where “robots.txt” appears 12 times (~1.5%)—usually fine if headings and context vary. Example 2: the same phrase at 4%+ with awkward repetition—trim and use synonyms or related entities instead.

When to use this

• Reviewing a draft before publishing SEO content.
• Checking whether a focus phrase appears at all.
• Spotting accidental keyword stuffing.
• Comparing two rewrites of the same article.
• Auditing product copy pasted from the CMS.

Common examples

• 800-word article: primary phrase 8–12 times with varied headings—usually natural.
• Product page stuffing the brand name every sentence—density spikes; rewrite for readability.
• Compare draft vs published body after removing cookie banners and nav text from the paste.
• Multi-word phrase “robots.txt tester” counted as a contiguous match, not separate tokens only.
• Thin 150-word page with 5% density on one term—add substance instead of chasing a percentage.

Common mistakes

• Chasing a magic density percentage.
• Pasting nav/footer boilerplate into the sample.
• Counting only exact match and ignoring entities.
• Stuffing keywords into thin pages.
• Ignoring readability for density gains.

How it works

Counts word frequency in pasted text and reports density (count ÷ total words). Use it to review whether a primary phrase appears naturally—not as a target to hit a magic percentage.

Formula or method

Density % = (keyword occurrences ÷ total words) × 100. Matching is case-insensitive on tokenized words; multi-word phrases count contiguous matches.
