Alt Tag

Every image on a web page has an Alt Tag. This tag often appears when the image is unable to load, or when moused over by the web site viewer.

Alt tags are significant for Search Engine optimization, since they help to define the Relevance of the page for a specific term. For best search engine ranking, the alt tag should contain the exact phrase that appears in the other tags on the page, including the title tag, Headline Tag, and Body Tag.
