Lots of people snub Alexa for providing statistics that are easily gamed, or lack relevance for the global market. As an example Jason Calacanis was recently proposing to test different ways Alexa can be gamed..
Om Malik recently reported on Alexa outages as large as 14 hours.
I still like using Alexa as a way to compare websites. But it is just one yardstick, and should only be used comparing websites in the same niche. If one webmaster uses Alexa and another doesn’t within a small niche, the difference in rating can be extremely high.
Alexa isn’t Just Down
I have noticed over the last week that Alexa wasn’t updating their statistics. They were frozen on 22nd November. Not just my own site statistics, but also for sites like CNN and Google.
Today is the first time that statistics have been updated for 6 days, and Alexa are now shoing statistics for… November 23rd.
This isn’t the same as an outage. There seems to be something going on behind the scenes.
They have still been gathering data, but not displaying the processed results.
Lots of tracking services have some level of delay, Google Analytics has a delay. MyBlogLog has a delay, unless you subscribe to their pro version.
Is this something to do with data centre migration or a technical hitch? If that was the case I would expect to see results today for November up until 28th now that things are moving again.
Alexa May Have Made Changes
The way that the data is appearing suggests to me that maybe Alexa have made some changes in the way data is being processed, and that it will take them a while to catch up.
Only time will tell.
