Alt tags | SEO Glossary A

Alt tags alternate text associated with a web page graphic that gets displayed when the Internet user hovers the mouse over the graphic. Alt tags should convey what the graphic is for or about and contain good relevant keywords. Alt tags also make web pages more accessible to the disabled. For example, a vision-impaired user may have a web browser that reads aloud the text and alt tags on a page. (For those familiar with HTML, "alt" isn't actually a tag by itself but an attribute to the "img" tag.). Note that the value of Alt tags for SEO have been discounted over time by the search engines to the point that now it is of minimal value.
