Hi, Recently my blog is being crawled by a lot of spiders namely googlebot,mediapartners,yahoo,bing,sphere,radian6,Spinn3r,TopBlogsInfo,urlfan and many more. Is this normal ? Is it good or bad? Yesterday alone my site has been crawled by around 5500 spiders.I'm worried if this is okay or not.Your inputs in this regard is highly appreciated. Thanks in advance!
There are some bots that aren't so good though that you can block. I have a list of unfriendly spiders somewhere and will post it if I can find it. I don't personally block them though as I have many sites and just don't want the extra burden.
You could simply block some of the spam bots. You can find a detailed list of spam bots here at http://seocrazy.blogspot.com/2008/04/spammy-robots-list.html
