Should I use a UK agency or an international one for AI search?
A UK-based agency offers practical advantages: understanding of UK search behaviour and market nuances, same time zone for meetings and communication, GBP pricing with no currency risk, and familiarity with UK directories and citation sources. International agencies may offer deeper technical expertise or longer track records. For most UK SMBs, a UK-based specialist is the practical choice. Enterprise companies with larger budgets may benefit from international specialists alongside a UK partner.
