Lately I see my sites moving all over the place, sometimes on first page sometimes 4th or 2nd page. It keeps changing constantly through out the day. Aol seems to have the only consistent google results. Whats going on with google?
Personalisation. I run two operating systems (Windows 8 & OSX) and multiple browsers on a Mac, and the results are often different on all of them. Then there's the iPad or iPhone - different again.
In fact recently I've been wondering if different screen sizes return different result sets. Example; if your on a 1000 pixel wide browser you get served the best site for that screen resolution.
I've seen this behaviour for a long time now and just recently I've noticed a trend of people reporting similar activity.
