The META Keyword Tag was used by the search engines in the 1990s but spammers quickly discovered that repeating a keyword over and over in this tag rocketed them to the top of the SERPs. The search engines had no choice but to ignore it for ranking purposes and this has now been the case for several years.
Although ignored for ranking purposes the tag is almost certainly still used to detect spammy pages so if you do decide to include it don’t be tempted to stuff it with everything you can think of.
The only real use is to remind you of the keywords and keyphrases you have optimized for on that page. The META Keyword Tag should be placed immediately after the META Description Tag.
Using the example page structure from the Description Meta Tag post it should look something like this:
<!doctype HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”>
<meta http-equiv=”Content-Type” content=”text/html; charset=iso-8859-1″>
<meta http-equiv=”Content-Language” content=”en”>
<title>Retail Store Fixtures and Retail Store Display Supplies</title>
<meta name=”Description” content=”All your retail store display requirements at discounted prices with next day delivery. An online catalog of retail store fixtures from G.Brown Company Inc.”>
<meta name=”Keywords” content=”store fixtures, store display, retail display, retail fixtures”>
<link type=”text/css” rel=”stylesheet” src=”/path/file.css”>
