Photographer better known than the President of Austria, based on Google?

An interesting post about a copyright issue on IPKat ends with the text:

Merpel's just puzzled to know why the court insists on referring to Natascha Kampusch as "Natascha K". Apart from the fact that various books and articles have been written about her -- and she has even written her own -- she appears to be better known than the President of Austria (a Google search gives her 898,000 hits to his 728,000). Oh, by the way, his name is Heinz F.

Is "hits on Google" a valid indicator of "how well" someone is known? A search for IPBiz yields 1,630,000 results and for IPKat 243,000 results.
