What is AI Engine Optimization (AEO)?

AI Engine Optimization (AEO) is the practice of structuring content, entity signals, and technical infrastructure so that AI engines cite your brand in generated answers. It extends traditional SEO to cover ChatGPT, Perplexity, Gemini, and Google AI Overviews.

Procurement & Sourcing

Procurement is a duopoly at discovery. SAP Ariba and Coupa each show up in 97% of buyer queries about source-to-pay and supplier management, visible across ChatGPT, Claude, Gemini, and Perplexity. NetSuite and Jaggaer follow close behind at 91% and 89% respectively, with Ivalua rounding out the top five at 80%. Head-to-head comparison data is too thin to declare winners — only Coupa appears in enough evaluation prompts to score, and it sits at the category median. This is a consolidated category with a clear top tier of enterprise platforms; no meaningful challenger or riser yet cracks the consensus shortlist.
