Most of the people say now Google not use Sand box. But i think recently i face sand box effect (not only that). Until August 26th my blog keywords ranking and daily visitors contentiously grow. After 26th august my daily visitors drop 300% (approximately). I already posted this issue in this forum. So I'm again not asking why my keywords positions drop. I have 1 month old new domain previously i used blogger sub-domain (7 months). However i found that my blog has one hidden link (one gadget) and 3 hidden text. Still Google indexing my blog but take too much time than previously. So is this Google's sand box effect? Google Analytics screen shot.
The real question to ask is how competitive the keywords you was ranking for are? New sites tend to get a boost in the beginning when first put up and if the words that you was getting traffic from are competitive then it makes since your new site dropped in ranking.
if your ranking dropped then first check your webmaster account, may be your site is effected with Google panda, Check your website content first then try to discover other possible reason of down ranking
My all the keywords ranking drop. I check Webmaster tool; Search queries it display my impressions and clicks drop 100% (august 31 to September 4th), but August 27th to September 4th impressions drop 91%
This boost keyword is "HP touch Pad $99". But now Google take lots of time (more than 24 hours) for index my blog than previous. And also i check putting my blog title in Ranking position checking services they display my keyword (Blog title) no in first 700.
