Affiliate Marketing Secrets

This is driving me absolutely nuts for the last week I’ve been fight over a keyword in google and no matter what I do, I can’t seem to get an accurate rank indication using google. Whenever I check Google.com, it keeps showing me in the No.1 spot but I keep moving up and down in the top 5.
Anyway, when I then check any other rank checker (online and offline ones) I get a totally different ranking, usually about No.11 for my main keyword.
I’ve logged out of my Google accounts, cleared all of my browser search history, cache and cookies etc. I even downloaded Internet explorer I checked with that. But each time I get these high rankings. So either I’m doing something wrong or EVERY single rank checker is??? I think it’s me but I can’t work out what it is and it’s doing my head in.. I wish Google would just leave the bloody search alone and stop personalising it!
Please help me, this is urgent because it’s an affiliate product launch and EVERY second counts. Every min I’m not No.1 I’m losing money.

Ok , I ‘ ve got a Imate running Windows Mobile, and I ‘ m getting less and less font of this phone . For voice , text , and basic address book, etc . functions it works fine . But when it comes to Internet, it downright sucks. I ‘ m unable to update to Windows Mobile, which means I ‘ m stuck with the most outdated Internet Explorer mobile browser ever . It ‘ s horrible , slow , and terribly unreliable . So I do a Google search for mobile browsers. The Firefox one only works on some Nokia phone, the SkyFire browser captures all my info on my servers – um, no thanks – I already have enough privacy issues dealing with my Facebook account. So the only viable option is the Opera 10 Mobile browser or the Opera 5 Mini. The Opera 5 Mini doesn ‘ t seem to recognize my keypad correctly – instead of the letters I expected to appear when I begin typing , a bunch of weird characters show up – which basically renders Opera 5 Mini unusable . Opera 10 Mobile on the other hand, is awesome. Here ‘ s my problem – I can only run it successfully right after installing it . As soon as I try to launch it at a later date , I get a dreaded “Opera Failed to Reserve Heap . . . Closing ” error , following which the application shuts down . If I uninstall Opera , restart my phone and re -install it , it will work again; but again – only for a short while . This is driving me crazy !! , How the heck do I get this browser to work ? I Googled the “failed to reserve heap ” error and found virtually nothing on the topic . Strange. Don ‘t people use this browser? Seems to me to be a potential market niche for Opera , especially considering it ‘ s lack of penetration in the desktop browser market .
