If you’ve noticed any changes in the traffic coming to your blogs from Yahoo! it could be a result of their New Version of it’s Search Crawler called ‘Slurp’ – (a crawler is the bot that Search Engines send to your site to index it).
Slurp is said to be faster and more efficient and will have to visit your site less and will use less bandwidth when it does.
Have you noticed any changes?
