Test how popular a website is compared to others
Why is it important?
This is a simple at-a-glance performance measurement of how popular a website is versus others, including whether that popularity is rising or falling.
It is particularly useful where more detailed information is not available (e.g. most organisations don’t have access to their competitors’ analytics).
How is it measured?
The Alexa ranking is used. This is based on the viewing history of several million web users.
Generally Alexa can give rankings for websites in the top 5 million – results are much more accurate the higher the ranking.
There are some biases in the data, but generally it is still very useful as long as it is used appropriately in context (e.g. more as a relative measure, “website A is more popular than website B”).
Alexa can only measure the popularity of entire domains, e.g. www.example.com. Sites with paths, e.g. www.example.com/news cannot be reliably tested. In these cases, Sitebeam awards 75% of the score from the whole domain to the partial site as an approximate. These occasions are clearly labelled on the results.
