Meta Description and keyword tagWe know html document consist of tags. Some of these HTML tags have no control over display of the page and they only used for search engines or for different robots who index the page. One of Such tag is meta tag. The most popular two Meta tags are Description Meta tag and Keyword meta tag.Description meta tag contains a full sentence to give the best description about the page. Google insist through its webmaster tool about the minimum and maximum length of the description tag. Keyword Meta tag consist of a set of different keywords used within the page. Webmasters use this tag to tell engines to rank this page for these set of keywords. However this tag is no longer considered by modern engines in their ranking but there is nothing wrong in having them. Let us start with some examples. Description meta tag Author name : This is a requirement of the google bot but again this is specific to engine and optional requirement. Content Follow : No need to tell bots to do this, by default they crawl and index the content. We can communicate some important information to engines through these tags. Here are some examples NoIndexSome pages we don't want to appear in search result, we can add this tag in head section.NofollowBy adding a nofollow tag we can tell engines not to follow or trust links posted in this page. In comment posting area of your site or any other place where user generated content is available, you may not like to vote for the links as spammers use such areas to post links.viewport<meta name="viewport" content="width=device-width,minimum-scale=1">Web page is not only displayed in computer screens but also in all mobile devices and tabs . To view large pages designed for computer screens, we can use viewport to scale down the page to small devices.
