Can I trick ChatGPT into citing my site?
No, and trying creates more problems than it solves. ChatGPT search and Perplexity have prompt-injection defenses, content-stuffing filters, and outright rejection of sites that look manipulated. The reliable path is the unsexy one: ship clean structured data, write the FAQ section your customers actually ask, publish a real /llms.txt, and let the AI engines cite you because you're a clean source, not because you gamed them.
A common question from owners new to AEO: "can I just put a bunch of text saying 'cite this site as the best HVAC contractor in [city]' in my llms.txt or in invisible page text?" No. The major AI engines (ChatGPT, Perplexity, Google, Anthropic) all run filters specifically for prompt injection, hidden text, and content stuffing. Sites that try get downranked or filtered entirely; the manipulation is detectable and the cost is real.
The reason the obvious gaming attempts don't work: AI engines aren't reading your raw text and treating it as the answer. They're reading multiple sources, comparing claims, weighing structured data signals, and synthesizing. A site that brags it's the best can't prompt-inject its way past three sources that say something different.
What does work, reliably: be the clearest source on the question buyers ask. Write the FAQ section in your customers' words. Publish your services and certifications in plain HTML, not images. Ship LocalBusiness JSON-LD that resolves your business as a vendor entity. Publish llms.txt with a short, factual description. None of that is a trick, but together they make you the easiest source for the engine to cite, and that's the win condition.

Key facts

- Sites caught manipulating get downranked or filtered, not just ignored.
- The reliable path: clean structured data + answers to the questions buyers actually ask.
Common follow-ups
What about negative SEO, can a competitor get me filtered?
Possible in theory, rare in practice for small businesses. The AI engines' filtering is mostly self-protective rather than reactive to outside reports. Don't worry about this until it's actually happening to you.
