The HTML Meta Tags help to keep the web pages updated in order to make them easier to locate and also prevents the pages from being framed. They are very useful for web developers and are used to identify creator of the page, keywords and description of the page. The two types of Meta Tags :
(1) HTTP – EQUIV and (2) Meta Tags with a NAME attribute. When a web browser requests for a document from the web server and clicks on a link for the page, the web server receives the browser’s request via HTTP. As soon as the web server has ensured that the requested page is indeed present, it generates an HTTP response. The Meta Tags with a “NAME” attribute are used in those Meta Tags that do not relate to normal HTTP headers.
Web owners desirous of getting the top ranking in search engines need to add “Meta Tags” to their web pages. The results would reveal immediate improvement in the ranking and may even skyrocket the website to a premier position in search engine listing. Nowadays, the most predominant feature of HTML Meta Tag is that it provides website owners the facility to control, to a certain extent, the way web pages would be described by search engines. It is also a way of preventing some pages from being indexed.
Meta Tags are information / details inserted in the headlines of the web pages. Only the Title Tag in the head area of a web page is seen by the browser while the Meta information is used to communicate information that a human visitor may not be interested in. Meta Tags inform a browser the type of “character set” to utilize or whether a website has self rated itself. The two types of Meta Tags are placed between the “opening” and “closing” Head Tags. For search engines the Title Tag plays a crucial role as the text incorporated in the Tag is the most important factor which determines how search engine decides to rank the web page.
The Meta Description Tag provides the web owner the tool to influence the description of the page in the crawler that supports the Tag. The text that is being depicted in the descriptive account goes between the quotation marks after the “content” portion of the tag. The initial segment of any page description comes from the Meta Description Tags. It is believed that it would be worthwhile to use Meta Description Tag for pages as it gives a certain degree of control over various crawlers.
The Meta Keywords Tag provides additional text for crawler based search engines and is useful in reinforcing the terms that the browser may think important. It also boosts the web page ranking and is beneficial as it reveals synonyms or unusual words that do not appear in the web page content. In such cases, mentioning the search term separately in Meta Keyword Tag guarantees that the website ranks better and is identified by the searcher. The Meta Robots Tag is supported by most search engines. There are other Meta Tags which are specifically designed for internal search engines to index.
