I have a weird problem. I have this 1 site that was doing fantastically, that has all of a sudden started to really struggle to maintain its rank. Everyday it seems to drop by 2-3 placings. See this image which should show what I am talking about Note: I run around 30 money sites, and I don't normally struggle with rankings - Most of my sites are on page 1 or 2 for my main keywords and have been that way for months to years. I want to know if anyone has any ideas on what is causing this type of SERP movement? The reason I am concerned is because I have used the same formula with lots of different sites, but this is the only one that is tanking. I'm honestly not sure what is going on. Any thoughts/suggestions would be appreciated - thanks.
