Meta tag is the coding used in the HTML of Meta data. Tags are instructions in HTML coding and the tags in Meta data are called as Meta tags.
Consider below example
<HEAD>
<TITLE>Yahoo! Mail: The best web-based email!</TITLE>
<META name=”description” content=” Description of the site”>
<META name=”keywords” content=”free mail, yahoo mail, mail ”>
</HEAD>
Each line is called as a tag in the above example and as these tags are used in Meta data, they are called Meta tags.
Explanation of each tag
Head Tag:
Any HTML will start and end with HEAD tag. All the coding is done in between head tag. Hence, a HTML document will have a HEAD tag for sure.
TITLE Tag:
A TITLE tag tells the browser what message it should display on the reverse bar when a user visits the site.
Look at the picture below
Yahoo should have used the following title tag
<TITLE>Yahoo! Mail: The best web-based email! </TITLE>, and that is the reason, internet explorer browser is showing that message in the reverse bar!!!
<META name=”description” content=” Description of a site ”>
Meta description tag allows you to influence the description of the site in the search results of some search engines.
Consider the example of Yahoo mail again. When someone enters the keyword “Yahoo Mail" in Google, it shows the description of yahoo mail in the following format.
Look at the description, "Yahoo! India Mail offers you free email with unlimited mail & photo storage, includes spam & virus protection, chat & free text sms from your inbox."
Though Yahoo! cannot have access the way the major search engine like Google shows the description in their search results, but it can still influence some of the search engines like Teoma.
<META name=”keywords” content=”free mail, yahoo mail, mail”>
Meta keyword tag is not effective anymore as most of the search engines ignore this tag. But for your information, Meta keyword tag tells the crawler of the search engine, what are the main keywords of a site.
