OK i was thinking about this, on my site most of the pages are dynamically created. On the dynamically created pages, let's say one is for brandx toothpaste, from within that page i dynamically create the pages depending on which of the different types of toothpaste they make. Anyway within those pages there is more or less a generic overview of the main brand itself. So now i'm curious for keyword searching in the overview is it good or bad practice to create h1, h2, h3 with the keywords linked back to the main toothpaste page? sorry if that got a little confusing, hopefully i was able to get across what i'm looking for. Thanks for any help.
