AdSense

This describes two modifications I have done to my sites Fivestar module. The first thing is to avoid indexing of words describing the rate levels "Star labels", like "Poor", "OK", "Good" and so on. While you are there you can always add relation attribute to avoid unnecessary follow of the rate link.

The second thing to do is to add comment tag to avoid AdSense analysing "Star labels" as content.

When using AdSense and dynamic generated content, like password and sentence generator you don't want google Adesense to index the generated content. Then you can ad a comment tag in your code to give AdSense a hint on what you want and not want to consider as your valid content. This is only used to find relevant ads, not for google search engine, as far as I know.
