Wished you had probed him to detail and elaborate on his theory: 'I suspect the main reason is that traffic numbers from server log data are inflated because of cookie deletion...'

What evidence does he have to support his suspicions? Also are other variables being taken into account to compensate for this, such as: IP addresses along with proximity of visits?

Guillaume: ask and ye shall receive. Here's a link to one of the comments to which I was referring:

I'll look forward to receiving your acknowledgment that I have a valid point.

I can also assure you that the Google Ad Planner monthly UV numbers are way lower than either comScore or Nielsen published data. if you e-mail me at gfulgoni@comscore.com I'll be happy to share the data with you.

"Separately, I've noted comments on the blogosphere from several site operators saying that their Google Analytic UVs are twice as high as their Google Trends UV numbers."

I was also told a friend of my sister's brother in law noticed the same.

More seriously, without names and data, this does not stand.
Plus most of the people will not use the correct value in analytics to compare with Trends (you have to search for daily uniques, most will stop at Visits.

In our personnal experience (non US, non english sepaking niche website with around 1 million uniques a month, something Comscore can not adress anyway) we found a 2% différence between Analytics (backed up by french mediametrie) and Trends. Pretty accurate.

Hello, nice post and discussion. Its aomething inevitable. when a new product/service is launched by google it always shatters all its competition. Google's ideology cannot be blamed..if its based towarsd there own company..every company has the right to present its offer and be biased towards its product.
But the fact that it results in drastic loss of business to others.

We can do nothing about it
