The Title Tag For Images Is Not Really Needed
The alt tag is the one that is now widely used and crawled by search engines.
What is the difference?
Our Example Image Code
<img src=”myimage.jpg” title=”this is an apple” alt=”red delicious apple”>
What it the image title tag for?
title=”this is an apple” – this is like a ‘tooltip’ that pops up in certain browsers when hovering over the image, especially in cases where a person has the pictures turned off in a browser
What is the image alt tag for?
alt=”red delicious apple” – this is crawled by a search engine to identify the picture (Google also scans pictures to identify them) and it also appears in place of a picture, especially in cases where a person has the pictures turned off in a browser
Long story short, I do not believe the title tag for links and images is needed or worth the effort anymore. I achieve rankings very fast without ever using this tag myself and have never found supporting evidence that it is beneficial for SEO.
So no, we do not need to use the title tag for SEO.
