[jeetendraets]

Hi,
What is alt tag in the on page SEO?

The alt tag is used to define an "alternate text" for an image. The value of the alt attribute is an author-defined text: <img src="abc.gif" alt="Free Tips">

Alt Tag is the HTML tag that tells search engine about the images. Because search engines cannot read text in the images, so with the help of alt tag, search engines come to know about images.
