How this tool works
Parses pasted HTML in your browser and checks visible markup signals.
The output is designed to make the next manual check clearer rather than turn SEO into a single score.

Review the output
Enter your inputs, then update the result.
Your input is processed in this browser unless the tool says it uses an external API.
What the result does not prove
It does not crawl the live URL, render external scripts or score content quality, backlinks, relevance or rankings.
Search visibility depends on crawlability, relevance, content quality, competition, links and many other signals. No browser tool can guarantee rankings.
Good SEO practice
Does this tool guarantee higher rankings?
No. It identifies a narrow technical or content-planning issue. Use the result with real page context and Search Console data.
Does the tool send my text to a server?
Most tools run entirely in your browser. The Website Speed Test is the exception: it sends the public URL you enter to Google PageSpeed Insights.
Should I repeat keywords more often?
No. Write naturally, answer the searcher's task, use descriptive headings and internal links, and avoid forced repetition.
