Different ranking on different softwares ? HELP!!!

Hi there

I am SEOing on my client's site.

On Market Samurai it shows 116 position.

ON it shows 170 :s

What is my real ranking ?

Crear all internet explorer cache and try again.

Rankings vary depending on a lot of factors, including the Google datacenters that delivers the results or the location of the user in the world. You could use a tool that checks multiple datacenters, like http://www.seologs.com/dc-rank-check.html. If that does not work I would stick with one rank checker, and check the rankings manually in a clean web browser with a proxy configured that originates in the country that you are targeting.
