Optimizing images is becoming more and more important in SEO (Search Engine Optimization) for Joomla websites and the ALT attribute is a critical step that is often overlooked. This can be a lost opportunity for better rankings.

In Google’s webmaster guidelines, they advise the use of alternative text for the images on your web site:

Use the alt attribute to provide descriptive text. In addition, we recommend using a human-readable caption and descriptive text around the image.

Why do they recommend we do this? The answer is simple: search engines have the same problem as blind users. They can't see the images.

The Image Settings

The Image Setting lets you assign a keyword or phrase to all images on your site or just to those that are missing an alt attribute.

This is a fast and convenient way to make sure all of your images have alt tags, and are compliant and optimized for search engines.
