SEO Content Analyzer

About SEO Content Analyzer

Good content is more than the right words on a page. It needs enough depth to answer the search, a structure readers can scan, and sentences that do not make people work too hard. The free SEO Content Analyzer grades your draft on all of that before you hit publish.

Paste your article text, add the target keyword, and click Analyze. The tool counts words, sentences and paragraphs, estimates readability with the Flesch Reading Ease formula, measures keyword density, checks whether the keyword shows up in the first 100 words, and rolls everything into a 0-100 score with a pass, check, or fail grade for each item.

What the analyzer checks

  • Length and structure: word count, paragraphs, and heading lines so the article is deep and scannable.
  • Keyword use: occurrences, density in the healthy 0.5-2.5% range, and an early mention in the opening.
  • Readability: Flesch Reading Ease plus average sentence length, so the writing stays easy to follow.
  • Actionable fixes: every weak item comes with a concrete tip, not just a red mark.

Run every draft through the analyzer as a final quality gate. A few small fixes before publishing are far cheaper than rewriting a page that never ranked.
