How We Tripled a Client's AI Citations in 90 Days, Perplexity Included BuiltBrilliant

The most common question about GEO is does it actually work, and the best answer is numbers we can stand over. In our AI search visibility case study, a B2B SaaS client went from being never-mentioned to a default citation in its category within 90 days: 3.2x AI citation share across 40 target queries, AI Overviews presence from 4 to 18 of those 40, and 4x referral traffic from AI assistants.

What was wrong before

The client ranked well in classic search and was nearly invisible in AI answers. When prospects asked ChatGPT for the best tools in the category, the model cited three competitors and never them. The diagnosis was specific: no llms.txt, minimal structured data, core claims buried in paragraphs, and no way to measure whether AI answers were improving.

What actually moved the numbers

Technical foundation. llms.txt, full JSON-LD entity markup, and pages AI crawlers could fetch cleanly, the checklist in our llms.txt guide.
Citation engineering. Core pages restructured around direct, quotable answers: a clear definition, a named statistic, and the why within the first 100 words.
Data-rich programmatic pages. Comparison and alternatives pages that gave models specific, citable facts, the technique in our programmatic SEO guide.
Distribution. A stronger presence on the review sites and comparison hubs models actually read.
Monitoring. A scheduled agent queried ChatGPT, Perplexity, and Gemini weekly to track citation share, with a Slack alert the moment a competitor displaced the client in an answer.

The monitoring is the moat

The results came in 90 days, but the durable advantage is the loop: the monitoring agent runs continuously, and displacement alerts let us respond in days instead of quarters. That is the difference between a campaign and a position, the argument at the heart of our AI share of voice guide.

The transferable lesson

The client was software, but the mechanics transfer to any category: be the clearest answer, structure it for machines, earn third-party presence, and measure weekly. The full playbook is our getting cited guide.
