We used to get good traffic from both google.co.uk and google.com as some mobile devices are set to use google.com by default and its still showing the correct listings for all other sites which rank in the uk search in google.com so its more curiosity as to why we were being penalized.
The other point is our not wanting to miss out on foreign visitors who are looking for hotels in Blackpool as it is a tourist hotspot so to speak.
We're clearing cache and checking in incognito browsers to check rankings and to add to the mystery some visitors (depending on isp's) see the sites on page 1.
Thanks for the offer of checking rankings, we have this covered.
