How To Use Alt Tag
In This Topic I Am Going to explain how to use <alt> tags in your images.
First of all, What is an Alt Tag?(see post: What is <alt> tag?)
So the code of the alt tab is
<img src="image/picture1.jpg" alt="picture description" />
So Basically Alt Tag is used for describing an image.
So if Google Bots crawls your page, the images will also be crawled by Google Bots using Alt Tag.
