The practice of crafting input prompts to elicit specific behaviors from large language models. In an AEO context, the prompts you optimize for are the ones your buyers actually ask AI engines.
For AEO purposes, prompt engineering is less about clever instructions and more about prompt discovery: understanding the exact phrasings buyers use when asking AI engines about your category. Tools like VibecodeAEO mine support tickets, sales calls, and search query data to identify the high-intent prompts that drive the most pipeline.
Real-world example
A CRM vendor discovers through prompt research that buyers ask 'what CRM integrates with HubSpot?' far more than 'best CRM software'. They publish a dedicated integration comparison page targeting this exact phrasing. Perplexity begins citing it in 80% of that specific query pattern within 6 weeks.
Frequently asked questions
What prompts should I optimize my content for?+
Optimize for: category queries ('best [your category] software'), comparison queries ('X vs Y'), how-to queries that your product solves, and your specific brand name. The highest-value prompts are the ones your buyers actually use — mine these from your sales call recordings, support tickets, and customer interviews.
How is prompt engineering different from keyword research?+
Keyword research targets Google SERP rankings. Prompt engineering for AEO targets AI answer citations. They overlap — question-intent keywords often match the prompts buyers use in AI engines — but prompts tend to be longer, more conversational, and context-dependent. AEO-focused prompt research prioritizes buyer intent over search volume.
