Here’s a presentation from the QCon conference about the architecture used by Quantcast to process 100s of TB of data daily using Hadoop.
In an article from Hitwise today, Hitwise used their data to determine that Craigslist had made it to the top of the weekly search results list beating 3 year champ, MySpace.
However, Techcrunch has a very different view based on a look at Google Trends. They rank Craigslist third with Facebook having a huge lead over MySpace. With different sites using different tracking methods, it’s no wonder we’re seeing such varied results. Keep your eyes open.
In addition to any on-site web analytics tracking that you might do using Google Analytics, Coremetrics, Omniture, or other solutions, there are a number of vendors who use other methods to provide information about who is visiting your website.
