Text to HTML ratio checker

What the text-to-HTML ratio measures

The text-to-HTML ratio compares the volume of visible text on a page to the amount of HTML markup required to present it. A page with a high ratio contains mostly readable content relative to code. A low ratio suggests that a large portion of the HTML is structural, script-heavy, or filled with non-content elements.

Why the ratio is a useful signal

Search engines aim to understand the main content of a page. When the amount of text is very small compared to the surrounding markup, it can be harder to determine what the page is about. A low ratio may indicate thin content, excessive reliance on templates, or heavy use of scripts and inline styling. This does not automatically mean the page is penalized, but it is a signal worth reviewing alongside other content quality checks.

How to improve a low ratio

• Add substantive content. Expand thin pages with useful, original text that serves the user's intent.
• Reduce inline markup. Move styles and scripts to external files where practical.
• Simplify templates. Remove unnecessary wrapper elements and structural bloat.
• Focus on main content. Ensure that the primary text is present in the HTML rather than injected by client-side scripts.

Limitations

The ratio is calculated from the HTML and visible text of a single page. It is a rough heuristic, not a ranking factor with a fixed threshold. Different page types naturally produce different ratios; a media-heavy gallery or a complex web application may have a low ratio without being low-quality. Use the result as one input among many when evaluating content and template efficiency.
