Google Search Results inconsistent from different computers

[devonkrusich]

Recently after some optimization activities - I do not see much movement in search rankings - my client is seeing the results on page 1 position 3 and I see page 2 for the same keyword.  How does Google change ranking based on past searches and how can I get an accurate picture of what the actual rank is?

Google will deliver personalized results including, but not limited to: browsing history, geographic location, etc.

For instance, if you've been to your own website and search for a specific term tied to your site, your site may rank higher on your computer because Google's been altered that you've been to the site before and might want to see it again.  This was a fun lesson for me when I was thrilled when one of our key terms hit #1 on my computer only to have the powers that be pull it up on their computer and it was at #6.  I use SEOMoz Rank Tracker and love it.

You can also use a tool like SEOMoz to get a decent measure.

Another option is to use private browsing and set your location as "USA" within the google preferences on the SERP page.
