GEO: ChatGPT and Perplexity as channels

Generative engine optimization is crisp pages an LLM can cite. Those same engines also show up as referrers.

Two meanings of GEO

Generative engine optimization: write answers that models can quote — FAQ JSON-LD, llms.txt, short Q&A. Geographic GEO: this product is for South Africa. Both are on purpose.

AI referrers are just channels

If someone arrives from chatgpt.com, chat.openai.com, perplexity.ai, claude.ai, or gemini.google.com, Cashline labels the channel. Same if you tag a link with utm_source=chatgpt. There is no invented “AI traffic score.”

What we publish for models

llms.txt lists the product, the Paystack plans, and the docs URLs. The FAQ page emits FAQPage JSON-LD. We do not publish fake review counts for a model to repeat.
