Image Alt Role in seo

Because search engines can’t read images, you need to use alt tags to help describe your image.

If you have an image of the Golden Gate Bridge during a foggy day, your alt tag should read something like this:

Alt=”Golden Gate Bridge covered by fog”

Here is what the full image code should look like:

<img src="" alt=”Golden Gate Bridge covered by fog” />

The key to creating good alt tags consists of three points:

Image needs a proper description, without keyword stuffing.
It should be keyword rich.
It needs to be short and to the point.
