Backstory: I have a niche website that was ranking #1 for about 10 keywords, in the top 10 for about 35 keywords, in the top 100 for about 150 more. The site is a few months old, so I finally decided to build a few links to it. This site has several other older domains redirected to it, so it's got a pretty decent authority rank of 64, these sites were all in my niche, but I've consolidated them into this one site. So, I figured I could make a reasonable amount of links pretty safely. I used a wide variety of anchor texts, including 'click here' and branded anchor text links, etc...to 50 different inner pages and hit each one with about 50-60 links. And...immediate dropping of rankings. Like, within 2 hours. This was on Thursday, and now it's Sunday. Everything has tanked. Some of the keywords I was #1 for are now ranging from #9 to out of the top 100. Keywords I was about #20 for are in the 50s to out of the top 100. This is across the board. Not one thing has gone up. I realize the positive effects of a link should take some time, so I wasn't expecting a huge bump right away, but I really wasn't expecting this massive drop. It doesn't matter if I sent any links to the page or not or if I used the keyword as anchor text or not. Every keyword has dropped. Is this normal? I've never had this happen before, so this is probably a huge noob question. Thanks for any advice you can give.
