It's really amazing and not good for us. I think, Google periodically crawl our site and checks links placed on other sites, If they found spamming or links placed on banned sites they might be caught such sites and placed them to in not helpful directory as many SEO's are doing same things and ranking will be so easy if you Google don't do such things.
The same thing hapened to my site http://www.cirurgia-plastica.com . It suddenly dropped srps from 4th position to 81st posituion for the search cirurgia plastica...
Yeah, same thing happed to my website. From 3000/per day ...i went to 500 ... Anybody manage to restore his website ? Maybe some few tips ? Thanks in advance.
i lost almost 90% traffic on 12 march and it comes back again on 28 march - it means i have no biz for 16 days i hope yours will be back normal soon. this change happens to almost everyone and i have this as third time of one year already. very heart breaking!
