Why do rankings show differentley when checked from different computers

[TexasBebe]

When I check for keyword rankings directly in Google or Bing, I find relatively high ratings. when my client checks at his location, he gets another ranking, much lower. What accounts for the difference?

[stubby]

One or both of you probably has personalized search results on, or localized search results on

Are you and your client in the same location/ city? If not, that could just be the answer as Google gives different results based on location.

Also, are you 'logged in' to Google Account while searching? Personalized (logged in) search results are different from search results that show up when you are not logged in. For e.g. If you searched for a phrase, and clicked on your site, then the next time you search similar phrase, your website will show up higher than it actually is for majority of users (including your client)

Personalized results.

• Location. If you are pegged as being in a different geographical location (San Francisco vs Palo Alto) you will get different results.

• User History: If you're logged into Google, you will get results based on your personal search history, +1's, etc.

When I'm doing my rankings checks, I make sure I'm logged out and my location is set to the most generic for my use case (in my case 'United States', but yours may be a state or nearby metro region).

Google uses your unique IP address to give you the most relevant results based on your past search activity through Google’s personalized search.  Your location can also play a role in this.

Use the SEOMoz rank tracking tool (http://ranktracker.seomoz.org/) for objective - non personalized or influenced - ranking results.

It can be one of many reasons, however if you want to be sure... The SEOmoz RankTracker will suffice correct placements.
