In my experience it takes a few months to get ranked on the first page from a standing start. Do you charge a set up fee? and have the monthly payment from month 1? Or do you work for free first, then charge once rankings are achieved?
Also, if there are any UK offliners offering this service, I would be curious as to what you can achieve, as (again) from experience, I've found that its a little more difficult getting large monthly retainers as compared with the US market (but maybe thats down to my mindset and nothing to do with external factors?!)
Anyway guys, would love to hear your thougts.
