The definitive comparison of Generative Engine Optimisation platforms. Feature-by-feature analysis across GEO audit scoring, AI citation tracking, schema generation, MCP integration, content tooling, and pricing. Updated March 2026.
The GEO tools market is fragmented. Some platforms focus on content creation (Frase.io, Scalenut), others on structured data (WordLift, InLinks), and others on analytics (MarketMuse, Clearscope). No single platform covers every dimension of AI discoverability — but some come much closer than others.
This comparison evaluates 8 platforms across 22 features that matter for GEO performance. Data comes from Innotek GEO audits, published product documentation, and competitor research conducted in February 2026. We include ourselves in this comparison because transparency builds trust — and our GEO audit data speaks for itself.
