ALT Attribute

The ALT attribute is used to define an alternative description for images on a website. This alternative description will be displayed in the browser if the actual image can't be displayed.


<img="" height="40" width="100" alt="This is the ASEOPS logo." />

This is the ASEOPS logo.

Search engines don't see website like humans do and don't recognize what's on a picture. That's why they look for this attribute, to see what the picture's about.

The ALT attribute can be used to influence a website's relevance for certain terms. That's why ideally the alternative description should always include the keywords you want to optimize the website for.
