My traffic had a nice spike on www.allmutt.com on Friday. I traced it back to Bing, they usually send less than 50 visitors, on Friday Bing sent 400 visitors which rivaled Google for the day. I did set up Bing Webmaster last month so I wonder if that triggered something. The traffic came from a lot of different cities and for a lot of different keywords. I hope setting up Bing Webmaster has Bing testing my pages for bounce back and other metrics. I'd be interested to hear if others have seen Bing spikes.
Yes if you set up the Bing webmaster tool , it surely helps you to get some additional traffic from Bing. Even I noticed that after doing that. But the volume is very less compared to Google. Actually it is not comparable at all!
