Google is always testing everything. In last two years they had hard time producing quality results. There are still trying to correct the mistakes. But how not to make mistakes when everything is new?

Results fluctuate all the time because Google tests your website with a combination of many other websites. Sometimes you are first and sometimes 4th and so on. Google every month with my forum goes from 60000 posts indexed to only 7000. Huge difference, but when I look into those 6000 posts I see mostly popular posts. Well not always.


So Google shows all your pages and sees how they will react to users then it cuts them down to those he is sure about. Constant change then testing. I don't think it is good system I believe in people and that we should control the results we want to see not the damn robots. Search engine powered by people for people.
