ChatGPT, Perplexity & Google AI Mode: Where Should You Actually Show Up?

“AI search” isn’t one thing. ChatGPT, Perplexity, and Google’s AI Mode each decide what to show a user in genuinely different ways. That means “optimizing for AI search” as a single effort doesn’t quite make sense. Here’s what’s actually different about each one, and where a business with limited time should focus first.

They’re not the same system wearing different logos

Google AI Mode is the most directly connected to everything you’ve already built. It’s a conversational search experience inside Google itself, which means it draws on the same underlying signals as traditional Google search and AI Overviews: your Google Business Profile, your website content, your local SEO fundamentals. If you’ve worked through the earlier posts in this cluster, you’re already building toward this one without a separate effort.

Perplexity works differently on purpose. According to Perplexity’s own explanation of how it works, every query triggers a real-time web search, and every answer includes numbered citations linking back to its sources. There’s no “training data cutoff” excuse here. Perplexity is reading the live web every time someone asks it something, and it’s the most transparent of the three about exactly which sources it used.

ChatGPT sits in between. It answers many questions from its training data alone, without searching the web at all, and only pulls in live results when it detects the question needs current information. That makes it the hardest of the three to influence directly. Your best lever is having consistent, credible mentions of your business across the web that could plausibly have made it into training data or a live search result.

Where to actually spend your time

Given limited hours, here’s a reasonable priority order for most service businesses:

Start with what feeds Google AI Mode, because it’s the same work as everything already covered in this cluster. A complete Google Business Profile, consistent NAP information, and clear website content with proper schema markup all feed this directly. There’s no separate to-do list here.

Give Perplexity a look next, but don’t overinvest. Since it always cites sources and always searches live, it’s the easiest of the three to actually test and see results from. And unlike ChatGPT, a single well-structured page can plausibly get cited within a reasonably short window, since there’s no training-data lag involved.

Treat ChatGPT as a long game, not a quick win. Because it leans so heavily on training data and broad web reputation, there’s no fast technical fix. The same fundamentals that help everywhere else (accurate information, real reviews, consistent mentions) are still the right investment. Just don’t expect to move this one quickly.

A two-minute check across all three

We covered this idea for a single platform in How AI Search Is Changing How Customers Find Local Service Businesses, and this is the expanded version. Open ChatGPT, Perplexity, and Google (with AI Mode) in three tabs. Ask each the same question your ideal customer would ask, something like “who’s a good [your service] in [your city].” Note whether your business shows up, and on Perplexity specifically, check whether your own website is among the cited sources.

Don’t expect identical results across all three. That’s normal, not a sign something’s broken. It’s the whole point of this post.

The fundamentals still carry most of the weight

None of this replaces the groundwork covered in What Is GEO (Generative Engine Optimization) and Why It Matters and How to Optimize Your Website Content for AI Overviews. Clear, structured, accurate content is what every one of these platforms is ultimately looking for. The differences above are about where that same groundwork pays off fastest, not a reason to build something different for each one.
