Hello, I had a site which receives 26k monthly searches (according to Google Keyword tool [exact]). It was the usual wordpress site, with 15 pages of content. I made some shitty links with a custom coded bot and AMR. My custom coded bot spammed my links on shitty photo gallery. These photo-galleries were always full of Viagra spam links. Using AMR, I posted the shittiest and most dupe article I could find for my site. My site was around 15th position before this, after this went down to 500+. Waited for two weeks, no improvement in the site..... What I did to neutralize it: Bought newdomain.com 301 redirect all pages from domain.com to newdomain.com As the site had only 15 pages of content, I decided to rewrite it a little. I made each article 20% unique compared to previous version. Created pages/videos on FB, Youtube, Twitter. Manually bookmarked with high quality description on top bookmarking sites. I did not do any other form of linkbuilding apart from what has been mentioned. What we can deduce from this experience? Google only passes on link juice when you 301 redirect your domains. It does not pass the penalties. Besides if it did pass penalties, I would have redirected my domain to my competitors domain. lol newdomain.com now ranks at 7th position for the same keyword.
