Success metrics vary by objectives but commonly include brand awareness improvements, customer acquisition cost reductions, increased customer lifetime value, and market share growth.

Establish clear KPIs upfront and ensure your agency provides regular performance reporting.

Leading UK agencies are rapidly adapting to AI-driven search and discovery. This includes optimising brand content for AI platforms like ChatGPT and Perplexity, developing voice search strategies, and creating content that performs well in AI-generated responses. Agencies should demonstrate understanding of both traditional SEO and AI optimisation techniques. Ask potential partners about their AI-readiness and approach to emerging technologies.
