The DESCRIPTION Tag
Where will the user see it?
The usual places for the description to appear would be in the page summary on a search engine. It is a tag that may or may not be used by a search engine. It is wise to use it, as some search engines will display your keywords if you do not have a description.
Size varies from one web source to another. Like every other aspect of a search engine they like their information short and sweet. We recommend no more than 25 words.
Search Engines are constantly changing the rules. Why? Because spammers find ways to get their pages at the top of the search engine list. Then users go to a different search engine. For the search engine, it pays to change the rules. Plan on reviewing your meta tags on a regular basis.
A little research and a plan makes life so easy. Please let us know if we can help you in this process.
