Meta tags provide useful information to some of the search engine spiders that will come visit your site after you submit it. You code meta tags into your HTML document, however they are not seen by someone viewing your page. They go between the head tags as show here. You can put meta tags on all of your pages if you want, but they should ALWAYS be included on the main opening page of your site. You should also include meta tags on any important entry pages you may have or a page that begins a main section.
The purpose of keyword meta tags is to highlight certain words contained in the text on the page. You choose the words that you want the seach engine robot to pay the most attention to. The purpose of the description meta tag is to briefly describe the contents of the page.
Here is what the HTML code looks like for meta tags:
<title>Your Descriptive Title Goes Here</title>
<META NAME="author" CONTENT="Your Name">
<META NAME="keywords" CONTENT="list of keywords goes here, separated by commas">
<META NAME="description" CONTENT="brief description of your page goes here">
A Meta Tag Example
Example of Meta Tags and a Title for a general page on the Beatles:
(If you have a more specific page, such as one on Sgt. Pepper, you should add keywords about that particular topic.)
<title>The Beatles: A Liverpool Odyssey</title>
<META NAME="author" CONTENT="John Doe">
<META NAME="keywords" CONTENT="beatles, paul mccartney, john lennon, ringo starr, richard starkey, george harrison, british invasion, sixties, 60's, rock music, rock and roll, liverpool, england, fab four, beatle">
<META NAME="description" CONTENT="An information page for sixties rock icons the Beatles from Liverpool, England.">
Do not repeat any variation of the same keyword in your meta tags more than three times. "german, germans, germany" repeats "german" three times. Do not go over this three limit or your site may be excluded from certain search engines. Always pick your variations wisely: "search, searches, searching" NOT "search, search, search".
