Before selecting an agency, consider the following factors:
Ask how the agency approaches visibility across Google AI Overviews, ChatGPT, Gemini, Claude and Perplexity. Look for a clear strategy rather than promises of guaranteed AI recommendations.
Technical foundations remain important. Review the agency’s capabilities in crawling, indexing, website architecture, structured data, internal linking and site performance.
Effective AI search strategies require useful, trustworthy content that answers real customer questions. Ask how the agency approaches topical authority, entity optimisation, digital PR and credible brand mentions.
Look for reporting that distinguishes traditional organic rankings from AI visibility, citations, brand mentions, qualified traffic and conversions.
The right agency should understand your business model, target audience and competitive environment. Compare proposals based on scope, expertise, deliverables and expected outcomes rather than price alone.
