I decided to rewrite some 300 files that I will use in a project, as they were originally written directly in google docs, and when saved as HTML, and seo ).
So what I would like to know is whether there really is a difference in the use of HTML text editing tags (italics, italics or any other) for SEO, and what the practical result is.
Will a page rank better in the results because it stops using <b> and starts using <strong> for example?
Google does not say anything about this, but that will not contribute anything to SEO. The most important things to consider is the page structure (use tags correctly, H1 for headings, sections, etc ...), meta tags and URLs .
It's the same as using classes/ids with descriptive names in HTML/CSS , for example, if I had a pet store and you're using classes and ids as in the example below, this will only do make the code look better and easier and clearer for you to read. But it will not help with SEO:
#menu.gato.cao { ... }
#menu.avestruz.animais.etc { ... }
Google prefers sites that load fast, have good structure, and have descriptive URLs. These are the things to focus on.
