Google is F*^king With me

So here is the issue.

Over the past several months I have been having success with ranking my websites on the search engines.

Its weird, some sites will quickly rank very high on Bing and Yahoo but not even show up in the top 100 on google. Other times they will rank well on google but not in the top 100 of bing and yahoo. I don't know, but I am getting off topic here.

This thread is to express my interest in an interesting quick I have found when searching for my website between computers.

On my main computer one of my new site ranks 14 in google. This is all nice and I will soon be moving up. Today I decided to search this particular term in google on my gaming computer which I keep separate from my work computer. This computer rarely browses the internet. For this specific term I showed up on the 5th or 6th page.

Does google decide that since I already spend time on this site I would like to see it more so than others.

Now here is the kicker.

Another site of mine is ranked 3rd-5th on a specific term on my work computer. I just checked it on my main and it showed up as the first ranking.

On my work computer I use Rank Tracker to save me time. On Gaming computer I just search from google. I guess Rank Tracker just uses my computer to search on google and the other SEs.

Anyway I just thought this was interesting.

Google, if you are reading this as I am sure you are. Please give rank up my sites for they provide the best content and look better than my competition. Thank you for all you have done for me and the internet I am very appreciative. I only want my websites to rank up a little, I am not asking for much, I know you only want to look out for your users and I respect that.

P.S.
In case you have not had enough of my ranting, a cool thing. The other day I was pissed that one of my sites had a bounce rate of 90%. So I did some research, fixed the site up. Only design changes. Now the bounce rate is down to 40% to 50% and the site has jumped up to first position on multiple keywords. This change happened overnight.

Word to the wise fix the bounce rate and Google will love.
