The whole concept of keywords is this:

Focus your quality content on keywords that your target market is searching for.
Make sure that your meta tags reflect the keywords focused on in your content. Meta tags are not as important as they used to be, but they do still count.

For one thing, it is your description and title tags that appear in the actual search results. If you don't have those, you don't get indexed at all.

If you really want targeted content, change your html extensions into php extensions and run targeted RSS feeds on your pages. Search engines read php includes, not java script.

Have an awesome day!
