I know google frawn upon too many backlinks created in short span of period as well too many links from single domain.. however, here what happend with me.. and now I need advice..
I working on a website from few months and then after all hardwork I finally launched it, hired a content writer etc and started working on it and everything was fine for a week and I even started receiving SE traffic but then suddenly site refused to open even for exact terms.. I investigated and I think I found myself in a FIX ..
What I did wrong that I used one of my established forum and used an 336x280 advt. to drive traffic to new website as I also have option for forum in this new site. If forgot to do rel="nofollow" which I generally do in such cases.
And now instead of increase in traffic its 0 .. the more I investigate, more it looks like sandbox thing.
I also advertised it on couple of other place (where I get again so many links at once) I completely forgot that I had plan to do it gradually..
So, now how do handle this situation, I m planning to remove all ads and also will no more build link for next 2-3 months (but I can't do about many current ones I already recieved)..
I don't think advertising your own site on another site you already own is bad and spam.. I know google knows this.. but now how I get out of it.. it really feels dreams like shattered after months of hard work (I know there are other SE but google always sends me around 80-90% of traffic )
