It could just be that some of the people who visited your site, have not had their DNS flush.
just wait it out a few more days and see what happens.
It has nothing to do with google s e, it has to do with you moving hosts / changing dns.
Sandino Reviewed by Sandino on . changing dns/host vs. google search engine ? I have recently moved my site to another host with dns changes, now after only a few days i have noticed a dramatic change of my google-search traffic in which it is almost %30 less, is there any negative side of changing dsn/host with google search engine ?
