Confused about internet stats?

You are not alone.

Data I have just seen has comScore Media Metrix and Nielsen/NetRatings differing by 20% on the number of unique visitors to and by 35% for YouTube!

Then there is all the talk I keep hearing about Alexa “being a little bit off lately”.

I think all you can infer from the precise data published is general trends.
