Alexa provides a fast and convenient snapshot of online audiences that anyone can take a look at. The data analysis tool, now owned by Amazon, tracks the trails of a massive panel of users by recording each and every page they visit. The panel lacks the representation of the higher end online measurement tools, but provides a useful starting point for measuring the relative reach, page traffic or user levels between sites. In this case the daily reach in the UK for five online newspapers is compared.
