Text in the Keywords field is used in the meta keywords tag of the page. This tag has limited importance in search engines today, because many sites have tried to improve their search engine ranking by intentionally overloading their meta tags with keywords.

Creating good keywords

• Enter keywords starting with the most important.
• Use only keywords found in the content of your page.
• Enter no more than 250 characters, including spaces.
• Since meta keywords are largely ignored by search engines, focus more on the words you use on your product pages. You can check daily estimated search traffic for your keywords using the Keyword Tool at SEO Book. (Note: You must register for a free account to use the Keyword Tool.)
