Wikirank shows you what people are reading on Wikipedia. It’s based on the actual usage data from the Wikipedia servers, which the Wikimedia foundation makes available as a public service. They take that data, process it, and give it back to you in a format that’s easy to use and share. Wikirank reveals emerging trends, and lets you embed relevant charts in blog posts and on social media sites.
From a technical perspective, the charts on Wikirank are based on logs from Wikipedia’s HTTP Squid proxy servers. That means every single page load is recorded, whether initiated by a human with a browser or a Web spider crawling through. Therefore, the numbers for a topic on a particular day can’t be considered absolute impressions the way, say, an ad server might count them.
The data of Wikirank indicates relative increases or decreases, so the shape of the charts is more important than the specific number of views. Comparisons are even more interesting, as relative interest in multiple topics can be ranked.
