Google AI Overviews and ChatGPT both answer questions like "best optometrist near me," but they pull from different sources and reach patients at different moments. Google AI Overviews lean on your Google Business Profile, reviews, and local search signals tied to a map location. ChatGPT leans on your website content, third-party mentions, and how clearly your practice is described across the web. For an optometry practice, both matter, but they influence different stages of a patient's decision to book an exam.
Where ChatGPT gets its information about your practice
ChatGPT does not have a live map of your city or a direct feed from your Google Business Profile. When someone asks it for an eye doctor recommendation, it draws on patterns learned from web content, including your practice's website, mentions in local directories, articles that name your practice, and how consistently your services and location are described across the internet. If your website clearly states what you treat, where you're located, and what makes your practice distinct, that language is more likely to surface in a ChatGPT answer.
This means the biggest lever for showing up in ChatGPT responses is not a listing you update once and forget. It's the actual substance on your website and the mentions of your practice elsewhere online. A page that says "comprehensive eye exams, contact lens fittings, and treatment for dry eye and macular degeneration" gives ChatGPT specific language to draw from. A homepage that only says "welcome to our practice" gives it nothing to work with. ChatGPT also tends to favor practices that appear in multiple credible places, such as local health directories, patient education sites, or news mentions, rather than relying on a single source.
Where Google AI Overviews pull local results from
Google AI Overviews are built on top of Google's existing local search infrastructure, which means your Google Business Profile, star ratings, review content, and proximity to the searcher carry direct weight. When someone searches "optometrist open Saturday near me," the AI Overview is generated from the same signals that power the regular map pack: business hours, categories, review recency, and how completely your profile is filled out.
For an optometry practice, this makes Google AI Overviews far more tied to bookable, location-specific intent. Someone asking this kind of question is often close to booking, and the AI Overview surfaces practices that are open, nearby, and well-reviewed. Keeping your Google Business Profile accurate, current, and rich with detail (services offered, insurance accepted, appointment types) has a more immediate effect on whether you appear in these answers than website content alone. Reviews mentioning specific services, like pediatric exams or LASIK consultations, also give Google's system more to match against specific searches.
Which engine matters more for booked exams and why
Google AI Overviews carry more weight for booked exams because they answer searches with clear local, transactional intent, such as "eye doctor near me that takes my insurance" or "optometrist open today." These are the moments when a patient has already decided to book and is choosing among nearby options. ChatGPT is more often used earlier, when someone is researching symptoms, comparing types of care, or asking general questions before they've narrowed down a location.
That distinction matters for how you prioritize your time. If a patient asks ChatGPT "what's the difference between an optometrist and an ophthalmologist," the answer they get shapes whether they think they need your services at all, but it rarely names a specific practice near them. If a patient asks Google "optometrist near me with same-day appointments," the AI Overview response is doing the work of a referral, and your practice either shows up or it doesn't. Because the second scenario sits closer to the actual booking decision, Google AI Overviews tend to have a more direct and measurable effect on new patient exams. ChatGPT still plays a role in whether your practice is described accurately and favorably when it does come up, particularly for research-stage questions about conditions, treatments, or what to expect at a first visit.
How to cover both without duplicating effort
Covering both ChatGPT and Google AI Overviews does not require two separate strategies. It requires making sure the same accurate, specific information about your practice exists in the places each engine actually reads from: your website for ChatGPT, and your Google Business Profile plus reviews for Google AI Overviews. The overlap is larger than it looks, because both engines reward clarity and specificity over vague, generic descriptions.
Start with your website. Every page should name the actual services you provide (comprehensive eye exams, contact lens fittings, treatment for specific conditions, pediatric care, emergency visits) rather than general phrases like "full-service eye care." This kind of specific language is what both ChatGPT and, increasingly, Google's AI systems use to match a practice to a specific question. Next, keep your Google Business Profile complete: accurate hours, updated service categories, insurance information, and photos that reflect your actual office. Encourage reviews that mention specifics, since a review saying "Dr. Lee caught my daughter's early nearsightedness during a routine exam" gives both engines more to work with than a generic five-star rating.
Finally, make sure your practice is described the same way everywhere it appears, including directories, your social profiles, and any local press or health-system pages that mention you. Inconsistent names, addresses, or service descriptions across the web make it harder for ChatGPT to build a confident picture of your practice, and can dilute the local signals Google AI Overviews rely on. Consistency across these sources does more to cover both engines than treating them as separate projects.
A one-week check you can run yourself
Pick five questions a patient might realistically ask, mixing research questions ("what does an eye exam check for") with local ones ("optometrist near me open weekends"). Run each through ChatGPT and through a Google search that triggers an AI Overview. Write down whether your practice is named, whether the details mentioned about you are accurate, and whether a competitor is named instead. If your practice is missing from the local questions, check your Google Business Profile for outdated hours, missing services, or thin reviews first. If it's missing from the research questions, check whether your website actually states your services in plain language rather than vague marketing copy. This gives you a concrete list of what to fix, in order, without guessing.
