Summary: no, not in the 1-on-1 "mechanical", algorithmic way.
What Is The Title Attribute?
It's not the <title> tag: the title element is the <title> of a web page.
The title attribute can be added to a lot of different HTML tags ("elements").
The purpose of the title is to communicate extra information to the end-user about the HTML tag it was attached to.
Here are a few links with a title attribute attached to it:
- <a href="https://www.example.com title="A domain from the IANA to use for examples">example.com</a>
- <a title="The Hidden Dangers by Jane Doe" href="https://example.org">illustrative examples</a>
My own favorite use for it is to add the title of the post or article I'm linking a word to.
What Does The Title Attribute Do?
When you hold your mouse over an element that has a title attribute set a tooltip will come up showing the text of the title.
Screenreaders may speak out the content of the title attribute depending on various factors. Those factors include: is it an image; a link; a link without anchor text; is the setting enabled; etc. etc.
Does Google Index The Title Attribute?
No.
There is no proof that Google adds information found in title attributes to its final index of the web.
There is no proof that Google uses text inside the title attribute for retrieval.
There is no proof that Google uses text inside the title attribute for ranking.
Why Not?
Maybe the potential for abuse is too high, a little bit like how using meta keywords quickly became useless for web search engines.
Possible Benefit of Title Attribute
Adding a title attribute is really one of those things you do purely for the user.
Doing things for the user is a good way of doing things. The happier the user the better the chance they stay on the site; and that can help convince search engines to rank you (a little bit) better.
