Hello , Let's check what happned when google update backlinks ! I can not believe in my eyes . Any one have any tuts to share?
That means you really built a lot of backlinks to your site. Did you used any paid services or did you done all that backlinks yourself?
Hmm i can't see anything wrong with backlinks they had an update but apparently you got affected really really bad from unknown reasons . You are sure that your website isn't deindexed?
getting backlinks from the same location doesnt get backlink to you and also not so much traffic to your site.
