I have a site with the keyword in its domain and I was on page 3 on google, #1 on yahoo and #1 on bing. It has made a decent profit in June but by the end of the month my Earnings per click dropped 50%, I was removed from google for that keyword from page 3 (Not banned I still rank for some other keywords), I was removed from Bing and still rank well in Yahoo. July is coming and I want to be able to make same profit.. What should I do and is somebody experiencing anything similar. Thanks for you help.
First thing you should do is enlighten us as to what your domain is, which page was ranking, and for which keyword(s). Is your site brand new (as in a month or two old)? If so then use the Advanced Search feature here to locate other posts about the Google "honeymoon" period. Here is a post I made on the topic previously, but it's been explained probably literally thousands of times on the forum.
I would also ask in what country. Those search engines are in over 70 countries. Some ranking can be higher in one country and it cannot be found in another.
