Calculates the ratio of visible text content to total HTML code on the page.
This check measures the percentage of your page's HTML that is actual visible text content versus code, scripts, styles, and markup. A healthy page typically has a content-to-HTML ratio of 25-70%. Very low ratios (below 10%) suggest the page is mostly code with little actual content.
While not a direct ranking factor, the content-to-HTML ratio is a useful diagnostic signal. Pages with very low ratios may have too much bloated code, excessive JavaScript, or simply lack meaningful content for users and search engines to work with.
An extremely low ratio may indicate that your page is bloated with unnecessary code, which can slow down parsing and rendering. Combined with thin content, a low ratio suggests the page may not provide sufficient value to users.
