Every website has a certain amount of back-end code and a certain amount of regular text in the front-end. The text to HTML ratio refers to the amount of text on a web page versus the HTML code on the same web page.

A good text to HTML ratio is anywhere from 25 to 70 percent. This percentage refers to the visible text ratio, as opposed to HTML elements, image tags and other non-visible information. You may notice that many high ranking websites in search results have visible text. This has become especially apparent since search engines, such as Google, released the Panda update which placed importance on content-driven sites.

The text to HTML ratio is not a direct ranking factor for search engines but there are many factors related to the ratio that indicate best SEO practices and thus may indirectly result in higher search rankings.

These related factors are:

  • Built for People: Web pages with higher text content to HTML tend to be more readable and understandable for people. It gives the impression that the site is built for people rather than search engines and so seems important in the eyes of the search engines.
  • Better User Experience: Higher text to code ratio indicates better user experience, and better user experience has become a prime search ranking factor according to Google and other search engines.
  • Better Page Load Speed: Less code indicates that any unnecessary HTML elements are not present in the code of a web page.¬† This increases the¬†loading speed of the page which indicates better user experience and again is a significant search engine ranking factor.
  • Better Indexing of Pages: A cleaner code and higher ratio of plain text makes it easier for search engines to crawl and index the site.
