Does H1 size really matter?
Part 1 of article
The question must be asked at least once, does size really matter?
If I insert a H1 that is size 7px at the top of a page, will Google and other major search engines index this H1 as normal or will it devalue the H1 or even possibly penalise a websites rankings. When you think it about from a logical perspective, a H1 should be like a newspaper heading, whereby the title is the largest text on the page. You never see a newspaper heading that is smaller than the body content. If Google has not caught up to this greyhat technique, they shall will eventually.

If we really need to decrease a h1 in size, why should Google and other major search engines index you highly in the SERPs, you obviously cannot display a bigger size heading that is relevant to the content and in which you want the readers to read. Imagine the sunday telegraph without its huge frontpage heading. The whole point is to catch the viewer from the first word and thus helping them to make a decision into buying the paper. I guess I will leave the end conclusion to your own opinions until part 2 of the article is brought out with the results.
Stay tuned for Part 2 when the results will be determined.
