Hi Cristian, It depends on what countries you are looking for. For larger web sites in the United States and the United Kingdom, the most reliable I'm familiar with is data from Nielsen-Netratings or comScore (www.nielsen-netratings.com and www.comscore.com, respectively). They are commercial media measurement companies, and I'm not sure how easy it would be get the data you're looking for, but they might have it on their web sites or they may be able to provide some for academic research (not sure what their policies are on this front). In addition to traffic they would also have information describing the profiles of people who visit the web sites. Nielsen-Netratings has much data on many European and Asian countries as well, but different countries may have other sources capable of providing far better information. For example, Gemius has extensive information about many Eastern European countries (www.gemius.com - by way of disclaimer: I am the founder & majority shareholder of Gemius in my day job ;-)), while AGOF has data about Germany and Audiweb has data about Italy (www.audiweb.it - whose data is actually provided by Nielsen-Netratings). Many other countries have other organizations which collect & publish this kind of data. Many of these organizations have very detailed data, but will only publish (relatively) limited information on their web sites. Each organization may be willing to provide more information for academic research, but I'm sure each company has its own policies in that area. Which countries are you interested in? I may be able to provide a more specific list if you narrow it down (unfortunately, I cannot think of a single "global" source that would be able to provide data that is equally-reliable across all parts of the world). All the best, Chris Modzelewski Emerging Analysis Corporation / Gemius S.A. Cristian Vaccari wrote:
Hi, I am looking for a good on line source for web traffic data on individual sites (including, but not only, weblogs). As far as I know, there is www.alexa.com, which provides rankings and users estimates based on its toolbar's users. Does anyone know of a more reliable source? Thanks,
