The rise of AI-powered search engines has fundamentally transformed how customers discover and evaluate businesses. With $4.5 billion projected global market size for AI-driven SEO tools and services by 2026, Generative Engine Optimization (GEO) has become critical for growth-stage companies. Unlike traditional SEO, GEO focuses on optimizing content for AI search platforms like ChatGPT, Google AI Overviews, Perplexity, and Claude.
For scale-up SaaS, B2B services, and e-commerce businesses, visibility in generative search results directly impacts qualified lead generation and revenue growth. The challenge lies in selecting an agency that understands both the technical complexities of AI optimization and the strategic nuances of B2B growth marketing.
