Ranking-factors: H1 to H6 in detail

johannes beus
One of the biggest surprises of the “ranking-factor-evaluation” was that, while the influence of headers of first order seem to be slim to non-existent, headers from H2 to H6 have an influence on the Google-ranking. Back then, I had sadly already done the evaluation of H2 to H6 together – who could have foreseen the results – which made it impossible for me to generate graphs for every headline.

Now, after Stefan Fischerländer has tried to get to the bottom of the weighting problem through an experimental setup, I decided to send my data through the parser again. Again, as I have said for the other evaluations: the graphs are not set in stone, are not claiming to be correct and they will only be meaningful with the correct interpretation :-)

H1

H2

H3

H4

H5

H6

Incidentally, Wikipedia is not using H5 for titles but is using it to format the navigation in all of their templates. This is a nice example for the fact that extremely strong domains, which show up in the SERPs relatively often, can have a strong impact on the results, even though a comprehensive data pool is used, which will therefore make it harder to determine the source and the consequences.

Tonight, I talked about this subject a little with FridayNite and Mediadonis at SeoFM.
