Short answer
An SEO readability checker highlights copy that is difficult to scan or understand. This tool measures sentence and paragraph length, reading time, long sentences, complex words, and structural variety, then turns the findings into a rewrite queue.
- Best fit: blog posts, service pages, landing pages, and tool guidance
- Outperformance angle: sentence-level findings and a copyable rewrite brief, not a context-free grade

Readability rewrite report
Readability checks that point to exact edits
A single grade does not explain what to rewrite. This checker identifies long sentences and dense paragraphs, shows the underlying counts, and creates a short editing queue you can use before publishing.
Built for web scanning, not simplified writing
Good web copy can still be expert and specific. The goal is to make the main answer, supporting evidence, examples, and next action easier to follow without removing useful detail.
Use after coverage and before the full audit
Check keyword coverage first, improve readability second, then rerun the On-Page SEO Checker. This order keeps clear writing connected to the query and avoids editing toward a generic score.

Frequently Asked Questions
What does the SEO readability checker measure?▾
It measures word count, sentence count, average sentence length, paragraph length, reading time, long sentences, long words, question usage, and list-like structure.
Does readability directly determine Google rankings?▾
No. Readability is not a guaranteed ranking factor or score target. Clear copy can still help users understand the page, complete the task, and find the answer they searched for.
What is a good average sentence length?▾
Many web pages are easier to scan when average sentences stay around 12 to 20 words. Technical topics may need longer sentences, so use the flagged rows as editing prompts rather than rigid rules.
Can I use this for landing pages?▾
Yes. It is useful for service pages, tool pages, product pages, and landing pages where the first answer, benefits, and next action should be easy to scan.
Is the pasted content uploaded?▾
No. The readability calculations run in your browser and the pasted text is not sent to FreelTools.
