10 year old domain with recent tune-up of on-page optimization. Quality content has been added. 2 months into the project and it's climbing the rankings like a rockstar. From almost being invisible to hundreds of visitors per day.
We've been Doing steady backlinking: article marketing, blog posts, and social media (close to 10,000 fan page tie-in) and bookmarking (social ADR bot and Social Monkee) It's been ranking high for 50 keywords. We added WSO Matt Laclear's article service (750 backlinks) to try to get to page 1 for more keywords. Suddenly the site has disappeared from Bing/Yahoo and dropped in Google. Traffic cut by 70% overnight.
Is this a slap from too many backlinks too quickly or just the bouncing around? I've never had a site bounce like this.
Any and all opinions and responses are greatly appreciated.
