Text-to-HTML Ratio Checker
Calculate how much of a page is visible text versus markup — a low ratio can be a thin-content signal.
Frequently Asked Questions
Is the Text-to-HTML Ratio Checker really free?
Yes — unlimited use, no signup, no credit card. We built these tools to help you audit sites without paying for a data subscription.
Does this tool store or share the URLs I check?
No. Each check runs live and we don't save your input. We keep a short-lived rate-limit counter (by IP) purely to prevent abuse; it is not linked to your results.
How accurate are the results?
This tool reads live, public data directly from the page or domain you enter — it does not rely on a paid third-party database, so it reflects exactly what is publicly visible right now.
Text-to-HTML ratio compares the amount of visible, readable text on a page to the total size of its underlying HTML code. It was a more commonly cited SEO metric years ago; today it's a much weaker signal on its own, but an extremely low ratio can still indicate genuinely thin content, excessive markup bloat, or a page that's mostly navigation and boilerplate with little unique substance.
How to Use This Tool
Enter a page URL and click Calculate Ratio. The tool strips scripts, styles, and HTML tags to isolate visible text, then compares that byte size to the full HTML size.
What This Tool Checks
Total HTML document size, the size of the visible text after stripping markup, the resulting percentage ratio, and an approximate word count of the visible text.
Understanding Your Results
There's no universally "correct" ratio — a data-heavy dashboard page will naturally score low without being a problem, while a thin affiliate page with mostly ads and little content will also score low, but for a genuinely concerning reason. Use this as one input among several, not a standalone verdict.
How to Fix Common Problems
If a content page scores surprisingly low, check whether it actually has enough substantive text, or whether excessive inline CSS/JS, ad scripts, or bloated theme markup is diluting the ratio. Moving inline styles to external stylesheets and trimming unnecessary wrapper divs both help.
SEO Best Practices
Focus on writing genuinely useful, sufficiently detailed content for the search intent behind the page — the ratio will usually take care of itself. Use this tool as a sanity check on pages you already suspect might be thin, not as a metric to chase for its own sake.
Example
A 500-word blog post wrapped in a heavy page builder's markup might show a lower ratio than the same content in lean, semantic HTML — that's a markup efficiency issue, not necessarily a content quality issue.
Common Mistakes to Avoid
Don't artificially inflate text just to move this number — padding a page with irrelevant text to change a ratio is exactly the kind of thin, low-value content pattern search engines are designed to discount.
