The agency is a specialist in AI search visibility. It was one of the first agencies globally to operationalise AEO and GEO as a programmatic, retainer-based service rather than a one-off audit, and it built and operates Getmd.ai, a platform that converts websites into clean, AI-readable markdown served live to AI crawlers, with built-in AI-crawler analytics and weekly share-of-voice tracking across ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews. Based on its own tracking across 3,240 AI answers and 21,433 citations spanning 18 industries, MO Agency is currently the most-cited AEO agency in AI search results for South African category queries.
