Alexa has changed it's ranking algorithm and a new and less Alexa toolbar dependent method is up and running. This would change the Alexa Ranking for some. Now the ranking data come from multiple sources that will enhance the ranking. But they are not telling us what those sources are! Perhaps to deter those who misuse the ranking or may be something that they forgot to announce.
Here are some Q&A from Alexa;
My site's ranking has changed. Was it wrong before?
Your ranking wasn't wrong before, but it was different. Alexa toolbar users' interests and surfing habits could differ from those of the general population in a number of ways, and we described some of those possible differences on our website. While the vast majority of sites' rankings were unaffected by such differences, we've worked hard on our new ranking system to adjust for situations in which they could matter.
The new rankings should better reflect the interests and surfing habits of the broader population of Web users.
Why are the long range graphs gone? I can only get 9 months of historical data.
We are recalculating historic traffic data and will continue to add it over the coming weeks. We apologize for the inconvenience, but should have several years of data back on line shortly.
Will you change the rankings again?
We are constantly working to ensure that we provide the most useful data that we can. We will continue to fine tune our algorithms but don't foresee any additional big changes. If you think something is amiss please let us know.
I liked the old rankings better. Are they still available somewhere?
We liked the old rankings as well. However, we developed the new system in response to the huge number of requests we got from users like you, and now that it's done we like it even better. We hope you will too.
We think that having more than one ranking system at a time would be confusing, so we have removed the old rankings.
Do you want to know what I think about this?
Definitely. We've been collecting suggestions and ideas for months now, and would love to hear more. If you have thoughts on what we've done so far, or ideas on what we should do next, please share them with us.
