It is true that the major search engines including Google, Yahoo and MSN have a tendency to ignore the Keywords meta tag; many of the other smaller search engines still make use of them. Keywords are also useful in helping you keep track of the particular words and phrases that you have designated for each page.
Use the following meta tag generator to help organise your meta data. Try and generate a different set of related and relevant tags for each and every page to optimise the chances of a high listing.
