My Site hcqe.com went from 1st position to 2nd page (17#), few days back for Earn Money Course keyword when nothing was changed. Not even backlinks. Of course, I did not promote my website for few months. But this was the case in previous month when I lost my position. Can anybody tell me why is it so? I do not have answer for this question. I checked competitors also. But nothing was changed to their websites or bls.
It could be for many reasons, but my first instinct is that you were hit with an anchor text over-optimization penalty.
