I think I should ask this question here because I don't know what happen to my blogs. My auto blogs only use social poster plugin and twitter tool plugin to get traffic, and they did good in the first two months, then suddenly traffic dropped down to 1/10. I have checked my google analyze account and I couldn't find out what happen because most of my traffic came from direct traffic. I noticed some of my blogs had been filtered by google and google don't index my blogs anymore. But you should know when anything went fine, my auto blogs got traffic in the first 2 weeks without search engine traffic. I mean I think my blogs never depend on search engine traffic, so what cause the traffic suddenly drop down? what is the possible reasons? and how do I deal with?
