The ratio of text to page codeChecks the ratio of the size of the text on a page to its overall size.
All search engines first of all pay attention to the ratio of the amount of content on the page to the amount of code. That is, the ratio of the size of the content (article) to the size of the code of the entire page.
There is no specific ratio, maybe there is, but no one knows it, but only one thing is known, the less code on the page, and the more unique text on the page, the higher the likelihood that your page will be higher in the search engine results.
This service allows you to find out the percentage of text on a page (useful content in the understanding of search engines) to the total size.
