Welcome to WebmasterWorld Guest from 18.104.22.168
We've been working hard behind the scenes for several months and are excited to announce that our new Alexa Rankings system is available.
Announcement link. [alexa.com]
We might have to find new things to say about the new and improved Alexa. There are no hints about where the new data sources lie, but I'd guess that aggregate data sharing arrangements have been made with large traffic sites such as ISPs and large portals.
If they are now aggregating domain-access data from ISPs and/or backbone providers rather than relying solely on their own Alexa toolbar data, then that means their numbers will be a lot less "meaningless."
The new numbers do look more accurate. In addition, it seems like they flushed the old bogus data. Good moves all around.
I have a site that has been in Alexa's 200,000-300,000 range rank for years. The US traffic has been diminishing, traffic from neighboring countries (talking about Central Europe) growing on that site.
Quantcast shows almost the same rank as pre-change Alexa (in the 200,000-300,000 range).
Now Alexa ranks the site to about 1,000,000 (1 wk. avg.) and 600,000 (3 mos. avg.).
I see the same drop of rank for a competitor in the same traffic range with visitors from the same geo area.
However, leading sites of the country (in the 2,000-3,000 ranking range) did not get the drop.
RogerD: "I hope this is an improvement. On one fairly busy site (quantcast top 5K), I saw massive declines in Alexa rankings that were completely in opposition to my actual traffic logs. I pretty much stopped believing them after that."
Observed almost the exact same thing - the new rankings are still lower than quantcast and my traffic suggest - but closer.
> Will they add more months/years as the results of the new calculation roll in?
I read somewhere that this will happen - they've probably purchased historical data as well.
