After I migrate from blogger to wordpress, according to Google analytics my bounce rate reduced from 70% to 40% (average), these days its less than 20%. According to the Akismet spam report there are 80-120 daily spam comments. When I was on blogger, there's no this type of spam issue. I use Disqus, but all the spam bots use WordPress comment system, so simply I can delete all of them at once. Are there any relationship with my site page preview, bounce rate and spam bots? Thanks!
