Determine your site traffic with the most popular free ranking sites: Alexa, Compete and Quantcast. Instead of using Comscore many opt for the freely available site traffic rankings sites, here is how they work.
There are 3 publicly available traffic sites: Alexa, Quantcast and Compete. Most in our industry not consider them statistically valid, and we do not rely on them for a variety of reasons including:
- Alexa extrapolates rankings from their data. The data is collected based on those individuals that decide to download their tool in their browser (Firefox just recently added) and Alexa then determines rankings based on their behavior. Anyone can download their utility and they may not control the sample. You may see wild fluctuations month to month due to their methods. Visit Alexa Here.
- Alexa is very similar to Alexa and individuals must install the Compete bar. Visit Compete Here.
- Quantcast has some basic data, however you must implement their code on your site so they can collect information about your site and visitors. This may be the most accurate of the three, so the data may be the most relevant. Visit Quantcast Here.
Each one of these sites is worth looking at as third party verifiers of your site activity.
