The engines
The move is the same on each engine and the sources are not. Ask the buyer's question yourself. Write down the Reddit URLs that show up. Those threads are the ones worth a useful comment. A comment on a thread the model never reads does not change the answer.
Perplexity shows the links. ChatGPT sometimes hides them. Google AI Overviews mix Reddit with docs and listicles. You still start from the question, not from a blog post about GEO. The ChatGPT page is the worked example. The longer citation guide on the main site is the one to send a teammate.
Start from the question, then the thread
Ask the buyer's question in ChatGPT, Perplexity, and Google's AI overview. Write down any Reddit URL that appears. Those threads are the ones worth a careful comment. A new post on your own site that repeats your headline does not enter that set by wishing. The ChatGPT page is the worked version. The longer citation guide on the main site is the one to send a teammate who wants the failure cases.
