Testing GEO/SEO with Adobe LLM Optimizer

I’m doing a test here to see what it takes to get LLMs (ChatGPT, Perplexity, Grok, Gemini, etc) to be able to take non-server-side-rendered text off of a page, and actually cite it in their responses.

My testbed: I recently wrote this post on our AEM Meetup in NC, and in that post I have a section “PDF resources from the event” which has an AEM Edge Delivery block that generates a list of related PDF files out of the AEM Cloud Service DAM. In that list, there are a bunch of AEM/EDS Architecture diagrams that should theoretically be GREAT for an LLM to cite. These are PDF files that LLMs tend to love, so long as they can find them. But right now, despite some good traditional SEO, zero of them are coming up.

Specifically, I’m trying to get a prompt (which I won’t put here as I don’t want to dirty the results) to cite this article or these PDFs. I’m measuring this using Adobe LLM Optimizer with a few variations of the prompts that I’m expecting someone to use when finding these documents.

One of the next things we’ll be trying in this experiment is using Adobe LLMO’s Optimize-at-Edge tech to generate pre-hydrated HTML specifically for the LLMs, so that they pick up this text that otherwise would be hidden from them.

Experiment kicked off today (2/24/26) – we’ll see where this goes!
