Piwik has launched as an open source alternative to Google Analytics under a GPL license which tracks popular pages, referring keywords, languages and is open for developers to build their own plugins specifically for their web analytics needs. [Live Demo]
Since Piwik is open source, SEO’s can adjust it to fit their company needs. For example, publishing sites may feel that referrals from Digg, Google News and Reddit are more important than the basic search engines and set up their reporting to flag these referral trends first. Bloggers and affiliates may want to view the amount or quality of outgoing links and reference them with referrals and specific keywords, the possibilities are limitless.
