AI vs. Google Local Business Visibility: What 25 South Carolina Searches Showed

AI discovery is not simply Google with a chat box on top. But it is not a separate universe either. A South Carolina test of identical local-service queries found substantial overlap, a few meaningful differences, and a much bigger gap between being known by name and being discovered before the customer has chosen a business.

Key Findings

Newsroom Snapshot

  • 50 South Carolina businesses in HVAC, plumbing, roofing, and electrical were included in 25 standardized recommendation-style local searches.
  • 19 of 50 (38%) surfaced by official domain in the AI search-backed retrieval snapshot.
  • 17 of 50 (34%) surfaced by official domain in the conventional live Google result sets for those same query strings.
  • 17 businesses surfaced in both environments. Two appeared in the AI retrieval snapshot but not the captured Google set; none were Google-only in this sample.
  • 31 of 50 appeared in neither captured result set for the relevant recommendation-style query.

These figures describe the sampled official domains under one day's standardized conditions. They are not statewide market-share estimates and they are not personalized AI recommendation rankings.

The important comparison is the same question, not brand search versus AI

One of the easiest ways to exaggerate AI visibility is to compare two completely different tasks.

Searching Company Name South Carolina asks a search engine to find a business the user already knows. Asking Recommend an HVAC company in Greenville, SC asks the system to choose among many possible businesses.

Those are different problems.

So for this study, SC Marketing & AI used the same 25 recommendation-style query strings in both the AI search-backed retrieval layer and conventional Google. That creates a cleaner question: when the wording is held constant, does the sampled business appear in each environment?

Nineteen of the 50 relevant official domains appeared in the AI retrieval snapshot. Seventeen appeared in the conventional Google result sets. Every one of those 17 Google-visible businesses was also present in the AI retrieval snapshot.

That left two businesses that appeared only in the AI retrieval environment (JB Plumbing in Greenville and Viper Electric of the Pee Dee) and 31 that appeared in neither captured set.

The result is more nuanced than "AI has replaced Google" or "Google rankings determine AI." In this small South Carolina sample, the two environments overlapped heavily on which sampled businesses surfaced, but they were not identical.

The larger difference was the evidence surrounding the answer

The company overlap tells only part of the story. The source mix around the same queries changed noticeably.

Yelp appeared in all 25 conventional Google result sets and none of the 25 AI retrieval sets. Facebook appeared in 22 AI sets versus 19 Google sets. Reddit appeared in 13 versus 11, while BBB appeared in 9 AI sets versus 12 Google sets. (Explore full source details in our Sources Shaping AI Local Discovery study).

That matters because a business can be present in both environments while the surrounding evidence is different. In other words, visibility is not just Do I rank? It is also What sources does this discovery system assemble when it tries to answer the customer's question?

Being easy to find by name is still much easier

The same SC Marketing & AI project also ran 100 branded searches across the full South Carolina research group. Ninety-four of those 100 businesses had their official site in Google's top 10 for the standardized brand query.

That number should not be put head-to-head with the 38% or 34% recommendation-query rates as though they measure the same event. They do not.

But the contrast is useful to a business owner: most companies are findable once a customer knows the name. The competitive part is getting into the conversation before the name has been chosen.

Traditional SEO is still part of the AI story

Google's own documentation says the same foundational SEO practices remain relevant for AI Overviews and AI Mode. Pages still need to be crawlable, indexed, useful, and eligible to appear in Search.

OpenAI likewise says sites need to allow OAI-SearchBot if they want their pages eligible to surface in ChatGPT Search. ChatGPT Search can also rewrite prompts into targeted web searches and use location context for local results.

So the practical strategy is not SEO or AI. It is broader discoverability:

  • Make the official site technically accessible and unmistakably about the business.
  • Create useful service and location information that answers real customer questions.
  • Keep major business profiles accurate.
  • Build a credible reputation across the sources customers already use.
  • Measure recommendation-style questions in addition to traditional keyword positions. (Read how in How Consumers Are Changing Local Search in 2026).

What to measure going forward

A local reporting dashboard in 2026 can track at least four separate things:

1. Branded findability: Can someone who already knows the business find the official site and profile?
2. Traditional discovery: Does the business surface for non-branded local searches?
3. AI/search retrieval: Does the official domain enter the source set for recommendation-style questions?
4. Generated-answer visibility: Does the business actually get named, described, or cited in the final AI answer on the platforms customers use?

Those are related measurements, but they are not interchangeable.

Methodology and limits

The study used 50 businesses from the larger 100-business South Carolina research group: 17 HVAC companies, 12 plumbers, 12 roofers, and 9 electrical companies. Twenty-five standardized prompts covered seven South Carolina markets. The prompt format was Recommend a [service] in [city], SC.

For the AI layer, a sampled business counted only when its official domain appeared in the search-backed retrieval result set. For the Google layer, the identical query was run through live DataForSEO Google SERP data, and a sampled business counted when its official domain appeared in the captured organic or local result structure. Data was collected August 8, 2026.

The AI retrieval layer is not a personalized consumer ChatGPT response and is not equivalent to being named in a final generated answer. Results can vary with time, location, personalization, platform behavior, and query wording. The sample is descriptive and should not be generalized to every South Carolina business.
