Six weeks ago I started a niche website/blog. Everything went well at first. I only got about 20 hits per day, but it was steady and people were actually staying on the site for a while. From the beginning, I used the SEO plugin by Yoast to optimize the on-page SEO, but nothing else outside the site (no purchased links, etc.). I run 2 AdSense ads on my site, and that's the only advertising. Then, a couple of days ago, something odd happened. My organic search traffic (which had been the main source of traffic) disappeared. Although I certainly hadn't been ranked very well at all, I had been getting a tiny but steady stream of visitors. Not only did the organic search traffic disappear, but when I searched for my site on Google, the results were weird. I could find my site by searching site:domain, but when using very unique keywords I might get one result (missing my favicon, I might add) whereas previously it would return many pages from my site. I read about Google penalties and I kind of panicked. Now I'm afraid that I've been penalized for something. There's only one TOS violation I can even remotely come close to thinking might have triggered something: too much use of a keyword. Unfortunately, my entire site is about one thing. Let's say "pies." So every page uses the word "Pie" a lot and in many variations- apple, cherry, blueberry, etc. It's completely natural and not keyword stuffing. There just aren't any synonyms. The other thing I realized was that my server went down three times (at least) last week. I tried to look at Google Webmaster tools to see if there was crawl error or something and so it dropped my site, but I honestly don't know enough to tell anything from the data. There weren't any messages or alerts on the account, and there's no way to contact Google about it unless you've had a manual action taken. It's really depressing to be working so hard on my site and have even its tiny bit of traffic taken away. Any advice would be welcome. I'm not an idiot, but I knew nothing about SEO until I started reading about it a few weeks ago. I'm doing the best I can with the limited time and resources I have.
