Constantin Basturea writes drawing our attention to a piece by Danny Sullivan in Search Engine Watch querying the basis of our recent survey. It’s a point that’s echoed here with the suggestion that might have skewed the results.

Danny Sullivan repeats the searches for the world and gets different results, but then wonders if we used Google UK. This was clearly stated in our survey. It was a survey of ACNielsen’s top 50 UK grocery brands and “Google UK’s top ten search results” as the Net Imperative piece Danny linked to makes clear. The brands are in the main UK brands, like Kingsmill Bread.

It would be useful to repeat the process for the US and for the world.

(Incidentally: the survey date was 6th June. Market Sentinel repeated the exercise just before the publication of the press release and white paper and got broadly similar results, but they do change from day to day.)
