To establish AI search authority and capture high-intent enterprise development leads across Generative AI platforms, we executed an advanced AI SEO and Generative Engine Optimization (GEO) framework for Appello Software Australia, a prominent custom software and digital product studio based in Sydney. By deploying semantic entity architecture, structured schema markup, and conversational answer-engine content blocks, we optimized the domain for LLM indexing across primary AI engines. As tracked in our AI search visibility performance reports, the campaign achieved an AI Visibility Score of 14 with 3 Direct AI Mentions and 28 Cited Pages across Google AI Overviews (19 cited pages, 2 mentions) and ChatGPT (6 cited pages, 1 mention). Additionally, these structural optimizations boosted traditional search performance, expanding total organic traffic to 267 visits (+73% growth) and ranking 393 organic keywords backed by 196 referring domains.
