So, I started my website a month and a half ago or so targeted for a specific keyword. I wrote a bunch of good unique content for the website and I have been slowly adding it to the website. While doing this I was noticing my rank go up, very slowly but it was progress and so I was happy. Now, however, I have still been building links and adding content but it's falling and I don't know why. a month ago I was up to 170 (terrible and I don't even know why it was so bad) and now I've fallen down to ~250. Any ideas or help?
