This is about a old blog(on blogger) of mine with random technology and blogging related articles. I have been carefully selecting keywords and write articles / how to's on each keywords with both onsite and offsite SEO. I am able to get rank for all the keyword on first pages and i could see increase in traffic with each keyword but somehow my traffic is always constant somewhat between 300 + 400 UV/day(mostly through google). I am adding tutorials daily but still the traffic is constant. CAN anybody suggest me hey this is happening?? I have heard about google filter, is this some kind of google filter which only sends 300 - 400 visitors. Because i have used this blog (on blogger) for spamming in the past where i have posted about 300 posts in 1 hour and i have this message where my blog is suspended for further posting. Need suggestions and thoughts on this about your experience with this. How can i overcome this??
