Hi Sean,
Thanks for the response. The keyword we are looking at is "B2B Events Agency" and the domain we are tracking is be.uk.com. We are testing from two different physical locations in the UK; London and Exeter, both using Google.co.uk
I've tried two different search profile on the Moz bar and that didn't reveal much. We've had a canned response from Rank Ranger about personalisation and location etc. but from what we can see it's a deeper problem than that.
Many thanks
