I know they like h tags. Is it possible to have too many? If I had a page with several h2 tags do you think it might throw up a flag? Maybe draw a penalty of some sort.
Testing your Headline also in-conjunction with your title can have some pretty impressive effects also. I am constantly changing my H1 tags and title tags to see what ratio of keywords to other text makes what impact. Often then not it results in a few places, but a few places is better then not gaining. Brad
