Use ALT Tag To Optimize Images
ALT tags are placed inside your HTML code as a text description for a graphic or image that appears on a web page. When spider crawls are performed, these ALT tags will allow the spiders to ‘see’ the image as indexable content.
Text will pop-up when the mouse hovers over the graphic or image on the page.
The following 2 examples are both images.
The first image does not use an ALT tag, the second does. Hover above each of them to see the difference:
As you can see in the second image, text pops up describing the image. Keep in mind that not everyone utilizes ALT or title tags, so not every image on every web site will display this text. It’s a personal preference.
FireFox does not display ALT tag text upon hover. If you are a FireFox user and are still able to view the text upon hover, it is because I also added a title tag. The ALT tag is sufficient for search engines to read, as a stand alone, nevertheless.
