The release of the 2026 top Generative Engine Optimization (GEO) agency shortlist highlights a critical shift in digital marketing: moving beyond simple SEO clicks toward direct pipeline attribution from AI search. Both B2B SaaS companies and local businesses are now investing heavily in strategies that earn explicit brand citations within platforms like ChatGPT, Perplexity, and Google AI Overviews.

B2B search intelligence agency Howl Louder Marketing has launched a specialized Generative Engine Optimization (GEO) service designed to help companies secure direct citations across ChatGPT, Gemini, and Perplexity. By combining GEO with traditional SEO and outbound lead generation, the firm aims to capture enterprise buyers who now use AI tools for vendor research.
