How this SEO checker works
This tool runs a quick on-page SEO audit of your draft against widely-used best practices. It checks how often your target keyword appears (keyword density), whether it shows up early in the content, how long the piece is compared to typical well-ranking content, and reuses our readability and passive-voice analysis to flag writing-quality issues that can hurt engagement.
If you add secondary keywords, the checker also tells you which related terms are already covered and which ones are missing, which is useful for making sure your content covers a topic comprehensively rather than repeating the same phrase.
What the score means
| Score | Meaning |
|---|---|
| 80-100 | Strong: your content hits most on-page SEO fundamentals. |
| 60-79 | Good: solid foundation, but a few checks need attention. |
| 40-59 | Needs work: several important checks are failing. |
| 0-39 | Weak: this draft likely needs significant revision before publishing. |
Tips for improving your score
Use your target keyword naturally within the first 100 words, and again a handful of times throughout, aiming for roughly 0.5-2.5% density rather than repeating it mechanically. Write toward 1,000+ words for informational content so you have room to cover the topic thoroughly. Keep sentences varied in length, minimize passive voice, and weave in secondary/related terms so the page reads as comprehensive rather than narrowly keyword-focused.
