Is the title attribute of a link taken into consideration by the search engines?
Title is a value that we can attach to balise <a>, among others.
Some browsers display the content of this attribute in the form of a tooltip on mouseover.
Various tests have revealed that the optimization of the content of this tag would not allow us to get a good ranking in search engines.
Despite everything, it is possible that search engines sometimes check on this attribute but it is hard to distinguish an overall generic treatment.
Using this attribute in a SEO logic therefore seems rather useless.
Even if it is part of an accessibility approach, the systematic inclusion of link titles is not mandatory.
However, be careful. You should still test it quite often because search engines might change their consideration.
