Still didn't understand how it happened. Let me explain the sequence .. * I went for a vacation for a week and didn't posted anything to my blog * When returned Google Traffic was reached to 0. No traffic came from Google for days * Did some tweaking here and there but nothing helped. * Finally I removed all my sitemap links and left it as it for 3-4 days http://www.thetechhub.com/atom.xml?redirect=false&start-index=1&max-results=100 http://www.thetechhub.com/atom.xml?redirect=false&start-index=101&max-results=100 http://www.thetechhub.com/atom.xml?redirect=false&start-index=201&max-results=100 * nothing helped .. so again I added the above and It was like a miracle. My traffic increased around 35-40%. This month I earned around 20$ which was all I got in past 3 months. you may even check alexa details http://www.alexa.com/data/details/main/thetechhub.com Can somebody explain why it happened?
There might be some other reason, as the reason you have mentioned above doesn't have significant validity..
Maybe the tewaking that you did on your site or when Google updates after Google-dance, because the sitemap has nothing to do with this i guess.
