What are the Keywords?
Keywords should correspond to the search terms people use to find your site. Your keywords can be a lot longer than your description. You can use about 150 words (1000 characters maximum) separated by commas. Place the most important keywords first and the least important at the end. It's good to include multiple variations of words like "create" and "creation" as well as multi-word phrases; however, some search engines will penalize you if you repeat keywords.

Since some search engines ignore the keywords tag, remember to scatter your keywords within the main text of your pages as well. This will help search engines find you based on the terms that are most likely to be used by people searching for your site.
