The Link title is an optionally defined attribute to give additional, advisory information about a linked web site. It helps clarify or further describe the purpose of a link that a recipient should know before clicking it.
Some email clients and web browsers display the link title as a tooltip when the recipient hovers over the link with a cursor. In a similar context audio reader agents can also read the link title information out loud.
In a HTML editor you can use the link title attribute as follows:
<a href="https://yourwebsite.com" title="My landing page">
