This report has been prepared by Privacy International following a six-month investigation into the privacy practices of key Internet based companies. The ranking lists the best and the worst performers both in Web 1.0 and Web 2.0 across the full spectrum of search, email, e-commerce and social networking sites.

The analysis employs a methodology comprising around twenty core parameters. We rank the major Internet players but we also discuss examples of best and worst privacy practice among smaller companies.

The report was compiled using data derived from public sources (newspaper articles, blog entries, submissions to government inquiries, privacy policies etc), information provided by present and former company staff, technical analysis and interviews with company representatives.
