Meta elements (Also known as Meta Tags) are HTML or XHTML elements used to provide structured metadata about a Web page. Such elements must be placed as tags in the head section of an HTML or XHTML document. Meta elements can be used to specify page description, keywords and any other metadata not provided through the other head elements and attributes.
Meta elements provide information about a given webpage, most often to help search engines categorize them correctly. They are inserted into the HTML document, but are often not directly visible to a user visiting the site.
Additional information about Meta Tags Attributes
The keywords attribute was popularized by search engines such as Infoseek and AltaVista in 1995, and its popularity quickly grew until it became one of the most commonly used meta elements. By late 1997, however, search engine providers realized that information stored in meta elements, especially the keyword attribute, was often unreliable and misleading, and at worst, used to draw users into spam sites. (Unscrupulous webmasters could easily place false keywords into their meta elements in order to draw people to their site.)
Search engines began dropping support for metadata provided by the meta element in 1998, and by the early 2000s, most search engines had veered completely away from reliance on meta elements. In July 2002 AltaVista, one of the last major search engines to still offer support, finally stopped considering them.
No consensus exists whether or not the keywords attribute has any impact on ranking at any of the major search engines today. It is speculated that it does, if the keywords used in the meta can also be found in the page copy itself. With respect to Google, thirty-seven leaders in search engine optimization concluded in April 2007 that the relevance of having your keywords in the meta-attribute keywords is little to none. However, the same article also suggests that Yahoo still makes use of the keywords meta tag in some of its rankings. Yahoo itself claims support for the keyword meta tag in conjunction with other factors for improving search rankings.
The description attribute
Unlike the keyword attribute, the description attribute is supported by most major search engines, like Yahoo and Live Search, while Google will fall back on this tag when information about the page itself is requested (e.g. using the related: query). The description attribute provides a concise explanation of a Web page's content. This allows the webpage authors to give a more meaningful description for listings than might be displayed if the search engine was unable to automatically create its own description based on the page content. The description is often, but not always, displayed on search engine results pages, so it can impact click-through rates. Industry commentators have suggested that major search engines also consider keywords located in the description attribute when ranking pages. W3C doesn't specify the size of this description meta tag, but almost all search engines recommend it to be shorter than 200 characters of plain text.
The language attribute
The language attribute tells search engines what natural language the website is written in (e.g. English, Urdu or French), as opposed to the coding language (e.g. HTML). It is normally a 2 letter abbreviation for the language name. It is of most use when a website is written in multiple languages and can be included on each page to tell search engines in which language a particular page is written.
The robots attribute
The robots attribute controls whether search engine spiders are allowed to index a page, or not, and whether they should follow links from a page, or not. The noindex value prevents a page from being indexed, and nofollow prevents links from being crawled. Other values are available that can influence how a search engine indexes pages, and how those pages appear on the search results. The robots attribute is supported by several major search engines. There are several additional values for the robots meta attribute that are relevant to search engines, such as NOARCHIVE and NOSNIPPET, which are meant to tell search engines what not to do with a Web pages content. Meta tags are not the best option to prevent search engines from indexing content of your website. A more reliable and efficient method is the use of the Robots.txt file (Robots Exclusion Standard).
NOINDEX tag tells a search engine not to index a specific page. NOFOLLOW tag tells a search engine not to follow the links on a specific page. NOARCHIVE tag tells a search engine not to store a cached copy of your page. NOSNIPPET tag tells Google not to show a snippet (description) under your a search engine listing, it will also not show a cached link in the search results
