The week of links continues, today Google gives recommendations on internal links. Their architecture is important for SEO. The ergonomics and the ease of navigation on a site often go hand in hand with SEO …

The architecture of the internal links of a site must be thought of from the specifications. This is an essential step if you want your site to be properly indexed by the search engines.

There are several things to keep in mind …

Important pages should be just a few clicks from the home page …
The category pages should for example be accessible from the home page simply via a menu. It is important to have a well-studied menu so that the engine can navigate the site easily. A site having only a simple search engine without categories / headings will be difficult to index by engines. In addition to the links to the categories, we can make links to the most important pages of the site.

Links must be understood from engines…
We prefer to use simple HTML links rather than javascript links.

… And have a consistent description…
It will make more sense for SEO to use a text link like “product name” rather than “click here”.

It is also necessary to verify that Google finds all the pages …
To do this, simply go to Google Webmaster Tools and go to the side of internal links. You will have to check the links that Google cannot find.

Optimizing internal links is one of the first steps to optimize your site for SEO, it is also one of the easiest to implement. Generally current websites and CMS are naturally optimized for this, without having to do anything more. All that remains is to check that the links are in HTML and that the link texts are relevant.
