Though meta keywords tags are not a major factor search engines consider when ranking sites, they should not be left off the page. Both the meta keywords tag and the meta description tag contribute to your search engine ranking. A meta keywords tag is supposed to be a brief and concise list of the most important points in your page.

Meta keywords tags should adhere to the following guidelines:

(1) keep your list of keywords or keyword phrases down to 10 - 15 unique words or phrases;
(2) separate the words or phrases using a comma (you do not need to leave a space between words separated by commas);
(3) do not repeat words or phrases;
(4) put your most important word or phrases at the beginning of your list.

A good idea is to copy and paste a strong, pertinent portion of your Directory Description into the 'Meta Description Field' Field.

This can then be copied and pasted into the 'Meta Keywords' Field and then all irrelevant words can be removed and the remaining words separated with a comma.
