What is META ?

Meta elements provide information about the web page, which can be used by search engines to help categorize the page correctly.

They have been the focus of a field of marketing research known as search engine optimization (SEO), where different methods are used to provide a user's website with a higher ranking on search engines. Prior to the rise of content-analysis by search engines in the mid-1990s (most notably Google), search engines were reliant on metadata to correctly classify a Web page and webmasters quickly learned the commercial significance of having the right meta element. The search engine community is now divided as to the value of meta tags. Some claim they have no value, others that they are central, while many simply conclude there is no clear answer but, since they do no harm, they use them just in case. Google states they do support the meta tags "content", "robots", "google", "google-site-verification", "content-type", "refresh" and "google-bot".

Major search engine robots look at many factors when determining how to rank a page of which meta tags will only form a portion. Furthermore, most search engines change their ranking rules frequently. Google have stated they update their ranking rules every 48 hours. Under such circumstances, a definitive understanding of the role of meta tags in SEO is unlikely.
