Welcome to the Q&A Forum

Hi guys, 4 weeks ago we launched a site www.adsl-test.it. We just make some article marketing and developed a lots of functionalities to test and share the result of the speed tests runned throug the site. We have been for weeks in 9th google serp page then suddendly for a day (the 29 of february) in the second page next day the website home is disappeared even to brand search like adsl-test. The actual situalion is: it looks like we are not banned (site:www.adsl-test.it is still listed) GWT doesn't show any suggestion and everything looks good for it we are quite high on bing.it and yahoo.it (4th place in the first page) for adsl test search Anybody could help us to understand? Another think that I thought is that we create a single ID for each test that we are running and these test are indexed by google Ex: <cite>www.adsl-test.it/speedtest/w08ZMPKl3R or</cite> <cite>www.adsl-test.it/speedtest/P87t7Z7cd9</cite> Actually the content of these  urls are quite different (because the speed measured is different) but, being a badge the other contents in the page are pretty the same. Could be a possible reason? I mean google just think we are creating duplicate content also if they are not effectively duplicated content but just the result of a speed test?
