New Study: AI Recommendations and Google Rankings Are Drifting Apart

Ask most chiropractors what they think when they hear “AI search is replacing Google,” and the reaction is usually one of two things: a creeping worry that everything they’ve invested in their website no longer matters, or a genuine confusion about what any of this has to do with running a local practice.

Here’s the good news: your SEO investment isn’t being made redundant. According to new data, it’s actually the single most important thing you can have in place before you can succeed at what comes next.

The practices showing up in AI answers right now all have one thing in common: strong SEO foundations. That’s not a coincidence.

Two Systems That Used to Be One, And Why They’re Splitting

Not long ago, ranking on Google and being found by patients were essentially the same thing. You optimized your website, climbed the rankings, and patients clicked through. Simple.

That relationship is changing. Research now shows the overlap between websites that rank in Google’s top organic results and websites that get cited by AI engines – tools like ChatGPT, Google’s AI Overviews, and Perplexity – has dropped from around 70% to below 20%. That means four out of five sources that AI recommends are not the same pages sitting at the top of traditional search.

This is what’s being called the SEO-GEO gap.

For chiropractors, this matters because the way patients find healthcare providers is shifting. Around 3 in 4 Americans now use AI tools weekly for research, and health information is one of their top use cases. They’re typing questions like “Who’s the best chiropractor near me for back pain?” into ChatGPT or asking Google’s AI Mode directly – and getting answers, not a list of links to click through.

What this means for your practice: Being findable through traditional search still matters. But being recommended by AI is a different challenge – and a growing one.

Why Strong SEO Is Still the Starting Point

Here’s the reassuring part, and it’s something the industry data makes very clear.

A website with poor technical SEO will fail to be indexed by AI systems in the first place. Site speed, crawlability, structured content, and domain authority – all of these are the entry ticket to being considered by AI engines at all.

Strong SEO is the necessary foundation for any successful GEO strategy.

In other words, if you’ve been investing in a properly built, well-maintained website, you’re not behind. You’re ahead.

The practices that are struggling with AI visibility are the ones that skipped the fundamentals – thin content, slow sites, no local authority signals, and no review volume. The practices that built their digital presence on solid SEO ground are finding that GEO layered on top of it works. The foundation is already there.

What GEO Actually Requires, and Why It’s Not Starting From Scratch

The study results make an important point: what performs in GEO is not a different type of website. It’s a deeper version of what good SEO has always rewarded.

Original research outperforms generic educational content. Specific, answer-first copy outperforms vague, keyword-stuffed pages. Genuine local authority signals – reviews, citations, consistent information – outperform thin directory listings.

If that sounds familiar, it should. These are the same things that well-executed SEO has always prioritized.

The difference is that AI systems are now extremely good at distinguishing between content that actually helps someone and content that was written to game an algorithm. The bar has risen. Generic doesn’t cut it anymore – not for GEO, and increasingly not for SEO either.

For a chiropractic practice, this means a few things matter more than they used to:

• Review volume and recency. AI systems treat your Google reviews as a real-time signal of trust and relevance. A practice with 200 recent, detailed reviews will be recommended far more readily than one with 40 old ones. This isn’t new – reviews have always mattered – but AI has made them even more decisive.
• Specific, localized content. Broad articles about “the benefits of chiropractic” don’t give AI systems enough to work with. Content that speaks to specific conditions, specific patient types, and specific locations is what gets cited.
• Technical site health. Page speed, mobile responsiveness, clean architecture. These are table stakes now – not optional extras.

The Gap Most Practices Are Missing

This isn’t a criticism of the way chiropractors have approached their digital marketing. The SEO-first strategy was the right approach, and still is. The issue is that most practice websites were built and optimized for a search environment that has evolved, and they haven’t had the guidance or the tools to evolve with it.

Most practices don’t have a strategy for their review generation. They don’t have content that directly answers the specific questions AI tools are responding to. And many are unknowingly blocking AI crawlers in their website settings, making themselves invisible to the very systems they need to be found by.

This isn’t about doing everything differently. It’s about adding a well-structured GEO layer on top of an SEO foundation that’s already working – and making sure that foundation is strong enough to support it.

The practices that are seeing the best results from AI search right now aren’t the ones that abandoned SEO. They’re the ones that treated GEO as the natural evolution of the digital strategy they’d already been building.

What the Next Step Looks Like

At Perfect Patients, we’ve spent over 20 years building digital marketing programs specifically for chiropractic practices. We’ve watched search evolve through every major Google update, through the rise of mobile, through AI Overviews, and we’ve made sure our clients’ practices kept up with every shift.

GEO isn’t a panic response to a changing landscape. For the practices we work with, it’s the next layer of a strategy that’s been building for years.

Our client saw her consultation conversion rate climb from 21% to 56% after we rebuilt her content strategy around the specific questions patients were actually asking. These results come from doing the fundamentals well, then adding the right tools on top.
