I was mildly amused today when I checked the stats of a new (yesterday) blog post, from Google's blogger, to see where the traffic was coming from and discovered it was BING!
I've never encountered such rapid indexing and traffic from Bing before nor have I seen any of my blog posts hit #5 for suggested search term so quickly.
The same blog post came in at #14 on Google for the same suggested search term which obviously isn't driving anywhere close to the traffic I'm getting from Bing.
Here's the interesting part is that Yahoo! which is now using Bing showed the same blog post at #40 for the same search term so Yahoo is definitely not just a clone of Bing's index. If you narrow the search terms in Yahoo! to include the specific part number mentioned in the blog post then it jumps to #3 but the more generic term doesn't rank anywhere close to Bing's.
Just an interesting observation.
