Each image is located on the web page should receive its own special attribute called the alternative text. This attribute is the tag "alt". The text, which is the data tags will be displayed to users in the event that the image was not downloaded, or if the image display was forcibly locked in the browser for some reason.
In conducting indexation modules search engine tag value "alt" is remembered, but in the process of ranking the results of processing a user request this value is ignored.
To date, we know exactly what the search engine Google, the text concluded in tag "alt", used only if the image serves as a reference to any other page. All other tags such as a search engine ignore. As for other search engines are no reliable information, but we can assume that the algorithms used in them are not very different from those used in Google.
In general, when you create a Web page would be good to use keywords within the tags "alt", although it is not critical.
