Question

so far i was doing it like this:

<a href="http://domain.com" title="Keyword"><img src="image.png" alt="Keyword" /></a>

Now, i discovered that images can have title attribute too:

<a href="http://domain.com" title="Keyword"><img src="image.png" alt="Keyword" title="Keyword"/></a>

Is there any other optimization i could pull off to boost image links value?

Answer 1

Think of the alt attribute as an alternative text replacement for the image. Imagine for a moment that you had to describe the image to someone who could not see it. That is the sort of information you should be conveying in the alt attribute.

Similar to the alt attribute, title is used for the same purpose. It helps to convey extra information about an element. You can apply the title attribute to most elements but you must give all your images an alt attribute.

In my opinion, having both an alt and a title on an image is redundant, especially if they are conveying the same information.
