my site > here had 22000 uv in 1 day next suddenly traffic got dropped,plz review what penalty thing may have caused
Well... There are probably too many ads above the fold, low quality content (and duplicated), there's no information whatsoever on who's behind the site etc... All in all, it looks spammy without a doubt.
But how come that compete.com reports nothing of your site? I check my sites with compete.com and it pretty much reports almost accurate data on traffic.
No offense intended, but you need some actual content, and less ads. When I think I have found some of the content it turns out to be ads by Google. Try to get you focus straight. Also, take ads off, and work on design and your main focus.
