I’ve already written several blog posts about Alexa and how notoriously bad its statistics are. Not really surprising that they are bad if you know how the data for those statistics is gathered. For the bulk of their data Alexa relies on people installing the Alexa Toolbar (or a toolbar that passes information to Alexa). It’s this toolbar that monitors to which websites you go and how you end up on them.
This has as a result that demographic, used browsers, and even the country visitors are from influence the data that Alexa gathers about a website. This can introduce serious artefacts and biases into the collected data and basically makes the statistics generated from it worthless. At best it can give you an idea about how well a website is doing, but that doesn’t mean that what you’re seeing matches reality.

Those that work in IT often know what those issues are and know what the consequences are for the data that’s gathered via those methods.

This has as a result that demographic, used browsers, and even the country visitors are from influence the statistics that Alexa gathers about a website. This can introduce serious artefacts and biases into the collected data and basically makes Alexa data worthless.

The blog post that I wrote about Alexa were all sparked by Anthony Watts using Alexa data to claim he’s doing better than his competition. His website is certainly big and it could very well be the case that he is outperforming his competitors. But Alexa is not the tool that you can use for determining if you are doing better than your competitor.
