I've seen some weird things happening today. I have a website, and I am trying to rank for a keyword related to this website, very competitive keyword. I ranked on the third page the last few days, been on second page for a like a day the other day. Anyways, I went to Google now and I typed the keyword and in it came up third on the first page. I was using Firefox. That looked weird so I went and checked it on Safari. I am 30th on Google when using Safari. Seocentro.com says I'm ranked 30th as well. So why is Firefox saying differently?
