What is a meta tag? It is a hidden tag that is found in the head of an HTML document. It supplies additional information about the document.
Don't be misled! Meta tags are not "magic beans" that will sprout your site to the top of the search pages. They are like everything else...just a tool. The meta tags will improve your position and standing in the search engines. But only the ones that actually use them. If meta tags are used in conjunction with other SEO strategies, they will help you further your site standings.
Another thing to remember: most search engines look at the body of text on your pages, as well as the page title. They take this information as higher relevance than any Meta tags. So, be sure to always have a relevant title on your pages, and relevant content in the body of the page. This will improve your rankings more than just meta tags alone.
Meta Tags will always be found in name/value pair. It can be any valid string, which you should enclose in quotes. Here are some examples of meta tags, the first two are the primary ones used for search engine optimization and the third is to tell search engines not to spirder a page.
<meta name="description" content="Decription of page is wrote here" />
<meta name="keywords" content="Keywords are place here and each keyword or kewword phase should be seperated by a comma" />
<meta name="robots" content="noindex">
