I running many site and now i have new idea to grow up with my brand very fast. I just want to know that if my domain got sandbox, what google will do with my domain ? 1. no listing on serps ? 2. dropped pr ? ... etc ... or what more ?
I suggest reading this first to see whether or not you're actually in the sandbox --> Am I in the Sandbox? How to Check The sandbox affects particular keyphrases, not entire sites ... therefore a drop in serps is the main effect (because PageRank doesn't matter)
There is no such "thing" like the sandbox!!!! Yes it did exist years ago, but when the noobs today are talking about the sandbox - forget it!!! But yes there are filters, (not talking about penalization thats a different issue and sometimes it's hard to averiguate if you "just" triggered a filter or caused a penalization), they often seem to cause similair effects like the former sandbox which leads to a lot of confusion. It's much easier/faster to get a filter removed than it was to get out of the sandbox in past days. The biggest problem is to know which of your changes/efforts/seo triggered the filter (sometimes more than one at a time). If you are able to spot the reason there is no problem to correct it and "reinstate" your rankings. Anyway some of this filters are by default restricted for the time applied, like the "to fast linkbuilding filters" which vanish usually after (at most) three months.
