Free SEO text checker and content analyzer
Great writing and great SEO content are not always the same thing. This SEO text checker bridges the gap: paste your draft and a target keyword, and it scores the text on the signals search engines actually evaluate — keyword density, keyword placement, word count, and readability — then layers AI suggestions on top so you know exactly what to fix.
How to check your text for SEO
- Enter your target keyword — the phrase you want the page to rank for.
- Paste your content into the editor (a full draft works better than a single paragraph).
- Run the analysis to see word count, keyword density, the Flesch readability score, and whether your keyword appears in the first 100 words.
- Apply the AI suggestions to fix thin sections, over-optimization, or hard-to-read sentences.
What the checker measures
- Keyword density — how often your keyword appears relative to total words, so you avoid both under- and over-optimization.
- Readability — a Flesch Reading Ease score that tells you whether your audience can comfortably read the text.
- Word count — a quick thin-content check against the 300-word minimum.
- Keyword placement — whether your primary term shows up early, where it carries the most weight.
