Code, to-Text Ratio

The code, to-text ratio represents the percentage of actual readable text on a webpage compared to the underlying HTML code required to display it. Historically, SEOs believed a high code, to-text ratio was a direct ranking factor. Today, it is understood that the ratio itself is irrelevant to the algorithm; Google only cares about the quality of the text and the speed of the code. However, an extremely low ratio usually indicates bloated, inefficient HTML or excessive JavaScript, which directly damages Core Web Vitals and crawl efficiency. Clean, semantic code is a prerequisite for dominating search results.

Code, to-Text Ratio Simplified

Code, to-text ratio is the mathematical difference between the words people read on your page and the hidden computer code used to build it. While the exact ratio doesn’t matter, having way too much messy code will slow down your site and hurt your SEO.
