I was reading Joost’s blog over the weekend and he was talking about Wiep’s post about Google SEO Mythbusting and I could not help but think about what my PhD supervisor used to give people grief about….statistically sound sampling.

Well this isn’t me being provocative, I don’t know Wiep but Joost does and having met him and read his blog that’s enough for me.

On 1, 2, 3 and 4, how long were they left, how many sites were these tried on, one single site does not maketh a fact . So each theory does not have enough data to be conclusive, or maybe it does, but those figures were not included.
With respect to the Adsense and indexing, many moons ago, it was the first thing that we did on large scale sites to get Mediabot looking. Then the speculation that it would be silly for MediaBot NOT to index the main index came about. I always thought this was a very good possibility which was why I never cloaked pages with Adsense and I could not be bothered with full IP cloaking. And of course:

AdSense mediapartners bot adding to the Google search index

Anyway, just my thoughs.
