I am trying to rank for a competitive keyword. It's about 1500 searches with cpc of about $300. Every day, I feel more and more like this keyword is manually moderated. I dont know why, it's just a gut feeling. None of the sites on page 1 are blackhat, if they are doing SEO, they have done a great job of hiding it because the backlinks look so real. I dont know if I should continue with this project or if I should abandon it. If this keyword is manually reviewed, I am screwed. How can I tell?
