There is some chatter and discussion in the Bing and Yahoo WebmasterWorld forums that an update is happening or started happening a few days ago.
Senior members are taking notice and one said:
Looks to me in the areas I traverse Bing has had a recent update. It practically looks like if you are not a known brand you might have taken a licking. In some areas I look at they're overrun with keyword domains which seem to be the exception to the branding. The merging of so many variations of keywords also is slowing the long tail and giving particular advantage to the “big boys”. Also too many weak e-zine type sites saying nothing. Prior to this I thought Bing was improving via a healthy mix.
At first I thought maybe it was just a hiccup but then I saw additional comments from webmasters and then a thread on a change at Yahoo, which uses Bing's index. That post said:
As of roughly midnight yesterday my statistics from yahoo! tell me something has changed with my yahoo rankings, or just in general.
The issue with this Yahoo post is that this same webmaster is claiming their traffic is up in Bing, which doesn't make too much sense to me. Typically, the results you find in Bing are the same as the ones you find in Yahoo.
In any event, I looked at my own traffic on some sites and there does seem to be slight changes in traffic in Yahoo and Bing and those traffic changes seem to correlate between the two in the same date range.
Here is an example for the past few days on one of my sites with Bing and Yahoo traffic overlaid:
Did you notice an update?
