Here is a little back bit of my backstory for context: A year ago, I started a niche website. Nothing crazy, but I put a lot of works and effort into this website. Now it has about a hundred pages of long and good quality content. My traffic was going up constantly for during that year. The google medic update was quite nice to my site. However, about 2 weeks I got hit. 50- 60% loss in traffic. I was ranking well for the main keyword of my niche (top 5), and now I see some 1 page spammy website in first page whereas my 5000 words ultimate guide is on page 3. To be honest this is sickening. Seriously I don't know what to do. Should I just wait or I should do something about it ?
