I was carrying out KW research this morning and I realized that Google listed only 4 results per page for “microsoft bpos”. For some reason I can not replicate this again, however, I still have the window open and below is a screenshot of it.

Google listing four results per page

Here is the URL http://www.google.com/webhp?hl=en#sclient=psy&hl=en&site=webhp&q=microsoft+bpos&aq=f&aqi=g4g-o1&aql=&oq=&gs_rfai=&pbx=1&fp=6f32b8af52b7e0b8

I have not altered anything in the search request, this is certainly interesting but I am not making any assumptions. How is this going to affect SEO?
