Is this the sandbox or google banhammer?

Hi,
i built some time ago a micro niche site and it made me good bucks. I ranked in the Top Ten for my 7 keywords. each with a different page one my site. But today i checked and all my pages werent in the top 100 anymore. But if i google my exact domain name (with http and .com) its still number one. So did i got deindexed or is it just the sandbox and it will come back again from alone. I just recently installed some amazon aff links on it ( which didnt made any money ) , could those be a reason for my rank lose? In the top ten for my main keyword another made for adsense site is still ranking in the top ten. I just dont know what to do at the moment? I removed instantly all the aff links and pinged my site. I also checked my GoogleWebmaster Tools and there was no problem. Any ideas what could have been happened or is it just the normal sandbox?
Thanks for your help!

sandbox. if you can still search your site name.

i guess thats good thanks a lot!

if your name shows up with site:domain.com then u are ok

BanHammer will de-index all pages of sites from Google search results and you will not see any result in site:domain.com so congrats you are still in search engine.

Sandbox or filter can be serious issue, some of my sites got out of it very easily, some are still there after 1 year...

Stop doing extensive backlinking for now... Only quality and theme based backlinks, regular updation, rotate keywords in your anchor text. Keep doing and your site should be back soon... For the time being just stop on those keywords, use related keywords for anchor text.

this usually happens for new websites, especially micro sites. Best thing to do is move on and rinse and repeat.

man for all those people thinking that the sandbox does not exist needs to actually test it out because i did and it does exist, the sad part about it is that i dont think it really matters about how many competing sites a keyword has i think its more of the traffic part targeting a keyword with a good amount of traffic gets you in the sandbox automatically i think..it sounds something like greedy ass google will do they want everyone to buy into adwords man screw that bs id rather wait 4-6 months do perfect link building during that time then buy their shit anyway
