Unnecessary To Add Title On All Links?

I know some SEO, but I have to ask: Is it unnecessary to add title on a link if there is no optimisation for that word or page (for example a link to a 'contact page', wich I don't

Solution 1:

Whether or not a link has a title applied is nearly irrelevant to SEO or little yellow hover messages (commonly known as tooltips). It's about semantics and meaningful content. Basically:

<ahref="/contact"title="free good software here find great stuff stupid idiotic keyword overload">Click here to contact us</a>

is a really terrible thing to do. title is meant to summarize the content of the link, but you don't need it if the content of the element accurately summarizes it on its own, as yours does. Putting identical content in both is also redundant.

A general rule of thumb: put title on a link when you need to describe it more. For example:

... or <ahref="/contact"title="Contact us">get more information about the product</a>.

Accessible and clean. Don't add a title attribute if you only want it for SEO.

A couple of years ago, Googlers confirmed they did not use TITLE attribute in the algorithm because it was used too seldom. This has changes since then but I still failed to spot any evidence that link TITLE attribute somehow influenced the rankings (you can run a simple test: include any non-existent word – that doesn’t exist in Google index – as a link title, wait for the link to be indexed, and in some time check if either the linking or linked page got ranked for that word). (...)

Conclusions on TITLE attribute usage:

• use it for your users, not search engines (this approach always pays back);
• don’t duplicate it with link text (this hurts usability: for example some blind users will hear the same text twice);
• don’t put too much weight on the title attributes as not all screenreaders may render it (make sure either surrounding text or anchor text explains the link at least the first time you use it).

Solution 3:

I don't think Google cares much about the title. I believe it just uses the text inside the anchor to identify the link. The title is just so the user can get additional information when they hover over it. If you don't want Google to follow or index it, use rel="nofollow".

So no, if the title provides no additional information, don't use it.
