PLEASE NOTE: THIS IS AN AUTHORITY SITE IN PROGRESS. IT IS BY NO MEANS AN "AUTHORITY" WEBSITE YET. This is my first stab at a proper "authority" website. The website currently has 32 articles on it that are all unique and very well written by me ranging from 350-750 words per article (average 500). That's nearly 16,000 words of content along with one image or more per article. I have been adding them steadily over the last 6 months. I have seen nothing but positive movement mixed with a little bit of dancing until a couple days ago... Two days ago something awful happened and everything took a turn for the worst. Almost every keyword dropped 100+ positions into oblivion. Screenshots (SerpBook & Ezee Rank Tracker): What I've been doing: I've been using SubRepo to harvest high pr web2.0 properties, register them and write my own content to link back to individual posts & homepage. I've also thrown a few social bookmarks at a few of the posts. I purchased an expired aged pr1 domain in my niche that had some high quality backlinks and 301'd to my website 6-12 months ago. My thoughts: I think I should diversify the types of backlinks to my website. I'm thinking of throwing a bunch of quality social bookmarks (~10 per post) at the website. Additional notes: No penalties in WMT. I've probably only built ~5 links over the last 2 weeks. Latest post was May 1. Ranks started dropping around May 2/3. This may have something to do with it? I am certainly not new to SEO but this is my first stab at a proper authority website. I wouldn't have any kind of issue if it was a single post that dropped but everything is dropping! I am very patient when it comes to waltzing with Google but this is something I've never experienced before. I had (and still have) high hopes for this website and have TL;DR: All posts on semi-authority website have dropped 100+ positions. There are only a few that are not in position 100+. I would love to hear people's comments and suggestions. I will post back in this thread if (or hopefully when) my rankings return to normal. I am extremely depressed this happened and am praying to jebus that my rankings return.
