Our forum www.satellites.co.uk/forums is around 15 years old, we have always enjoyed excellent ranking on google until about 2 years ago when our google search traffic dropped by around 50%. at a similar time we moved from a US based host to a UK based host. About a year ago we moved from vbulletin to IPB which again had a major effect on our search traffic which we hoped would recover but after no improvement after a year we decided to switch to xenforo. We have now been using xenforo for around a month and we have seen a slight improvement and the post count is up I still feel with the amount of threads and posts we should be ranking much better with google. When checking google analytics it appears most of our search traffic is coming from the UK, with a little from europe and next to nothing from any further afield. The content on our forum does have a global appeal and I have a feeling that the combination of a UK host and a .co.uk domain is costing us a lot of search traffic, would it be worth switching to a .com domain or is there something else that i'm missing that could be the problem ?
