I cannot figure out why my site got hit, hopefully somebody can enlighten me: 1. I created a multi-niche site, with over 25 niches are related to mobile gaming (each page being a different game). 2. Each post had a 400-500 word article hand written by me. 3. I kept the keyword density to around 1%-2%. 4. I built about 50 backlinks to the site. Each link was done by me, with high quality content. I used Article Directories, social bookmarks, web directories, press releases, basically the "high quality" tier 1 platforms. On January 10th, the site took a huge hit in traffic. None of the backlinking I did seemed to have even worked, as Google Analytics told me almost all of my traffic (about 1.5k-2k UVs/day) was coming from long tail keywords that I didn't know (coming under the "not provided" term). One last thing I'd like to mention, is I haven't updated this site since August. Does Google penalize sites for not updating? If they did, I wouldn't think it'd be on the exact same day they happened to roll out another update to their algorithm (January 9-10). I've disavowed all of the links I previously had built to it a couple weeks ago, but it looks like nothing is changing. Do I have any options here?
