Text to HTML ratio checker

Free Text-to-HTML Ratio Checker — Analyze Content vs Code

This tool calculates the ratio of visible text to total HTML code on a page. Enter any URL and you'll get the percentage of the page that is actual readable content versus markup — a quick health indicator for both SEO and performance.

The text-to-HTML ratio isn't a direct ranking factor, but a very low ratio is a useful warning sign. When a page is mostly code and very little text, it often means bloated, inefficient markup, heavy inline scripts and styles, or a thin-content page with little for search engines to work with. Lean, content-rich pages tend to load faster and give crawlers more substance to assess for relevance. A healthy ratio commonly falls somewhere around 10–25%, though this varies widely by page type.

Use this tool to spot pages that are unusually code-heavy (a hint to clean up bloated markup or move inline CSS/JS to external files), to identify thin pages that need more substantive content, and to compare a page against competitors. Treat it as a directional signal rather than a target to game — the goal is genuinely useful content delivered with efficient code, not a magic number.
