A lot of generic GEO advice treats AI visibility like there's one playbook that works for everyone. Get on Wikipedia. Get on Reddit. Get cited by G2. In reality, which sources actually matter depends entirely on your industry, and sometimes even on the language you're monitoring in. That's exactly why looking at your own project's data matters more than following a generic checklist.
Same Category of Question, Completely Different Sources
Take a look at what AI models cite when answering questions in two different categories.
For a social listening tool, the top cited sources are things like Octolens, Sprout Social, SurveyMonkey, and a Reddit thread from r/AskMarketing.
For a furniture and home decor brand, the picture looks nothing like that. The top sources are Polish interior design and lifestyle sites like AD Polska, czterykaty.pl, trustmate.io, and sfmeble.pl.
Same structure, same kind of table, completely different set of domains. That's not a coincidence, it's because each industry has its own ecosystem of trusted content, and AI models cite what's actually authoritative and relevant within that specific space.
It's Not Just the Industry, It's the Language Too
The language you use in your prompts changes what gets cited too. Monitor your brand with English-language prompts, and you'll mostly see English-language sources rising to the top.
Switch to prompts in Polish, and the citation landscape shifts toward Polish-language sources instead.
This is a detail that's easy to overlook, but it has real consequences. If you're optimizing for visibility in a specific market, the sources worth targeting aren't the global ones everyone talks about. They're the ones actually showing up in your language, for your prompts.
Why This Matters for Your GEO Strategy
You've probably heard that Wikipedia is one of the most important sources for ChatGPT. That's true for a lot of categories, but not all of them. In some industries, Wikipedia barely shows up at all, while a handful of niche blogs or community forums do all the heavy lifting instead.
This is exactly why there's no one-size-fits-all approach to improving your AI visibility. The only way to know where to focus your content and outreach efforts is to look at what's actually being cited for your prompts, in your industry, in your language. That's what your project's source data is for, it turns "get more citations" from a vague goal into a concrete, ranked list of the exact domains and pages worth targeting first.
