GEO vs SEO: what small businesses should actually do about AI search

If you own a small business, someone has probably told you by now that SEO is dead and you need GEO instead. Usually that person is selling GEO.

The real picture is calmer. GEO and SEO overlap heavily, most of what gets you into AI answers is what already helps you in Google, and a few things are worth doing differently. Here’s how to tell them apart.

What is GEO?

GEO stands for generative engine optimization. It means making your business and your content easy for AI tools like ChatGPT, Perplexity, Gemini and Google’s AI Overviews to find, understand and mention when they answer someone’s question. The term comes from a research paper presented at a computer science conference in 2024. You may also see it called AEO (answer engine optimization) or AI SEO. They mean nearly the same thing.

GEO vs SEO: the actual differences

• The goal. SEO aims to rank a page in a list of results so people click it. GEO aims to get your business named or cited inside an answer, whether or not anyone clicks.
• The unit of competition. SEO is mostly about the whole page. In GEO, a single clear passage or fact can be the part that gets used.
• How you measure it. SEO has mature tools for rankings and clicks. AI answers vary from one person and one moment to the next, so measurement is rougher.
• The foundation. This part is the same. An AI tool can’t use a page it can’t find, read or trust.

Is SEO dead?

No. Google’s own guidance on AI features says “there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary.” A page just has to be indexed and eligible to appear in Search with a snippet. That only covers Google’s own products, and tools like ChatGPT and Perplexity work differently, but they still need to be able to find and read your site. SEO fundamentals cover that too.

What has changed is how many people click. In a 2025 Pew Research study of 900 U.S. adults, people clicked a regular search result on 8% of visits when an AI summary appeared, compared with 15% when it didn’t. They clicked a link inside the summary on just 1% of visits.

The exposure isn’t equal, either. Early reports suggest sites that depend on general information, like how-to and recipe content, are feeling this most. A search like “crane rental near me” or “IT support in Honolulu” usually means someone wants to hire a business, and an AI summary can’t do that job for them. The evidence here is still patchy, so your own numbers matter more than the headlines.

What the research supports

The original GEO paper tested changes to web content across about 1,000 queries. Its findings are useful, with one big caveat.

• Adding evidence helped most. Citing sources, adding quotations and including statistics improved a page’s visibility in AI answers by roughly 30–40%.
• Keyword stuffing didn’t help. The researchers found it offered “little to no improvement.”
• Lower-ranked sites gained the most. In their tests, the site in fifth place saw the largest lift, which is encouraging for small businesses.

The caveat is that most of this ran on a test engine the researchers built, with a smaller check on Perplexity. It didn’t measure customers or sales, and today’s AI tools have moved on. Treat it as good direction, not a formula. If someone quotes you “up to 40%” as a promise, that’s the number they’re stretching.

What to do

1. Make sure the machines can get in. Check that your site is indexed in Google Search Console, and that your robots.txt file and firewall aren’t blocking the crawlers you want. Cloudflare began blocking AI crawlers by default on new domains in 2025, so a site can be shut out without anyone deciding to do that. The bots do different jobs, too. OpenAI’s GPTBot and OAI-SearchBot are controlled separately, so you can decline model training and still appear in ChatGPT search.
2. Publish the specifics. Say what you do, where you do it, who it’s for and what it costs or what affects the cost. Vague copy gives an AI tool nothing to repeat. On the Snell Crane Service site I built, that meant a page for every crane with specs and load charts, plus more than two dozen pages for the areas the company serves.
3. Answer real questions plainly. Take the questions customers ask you on the phone and answer each one directly, with the answer in the first sentence or two under a clear heading. This helps human readers just as much.
4. Back up your claims. Use real numbers, name your sources and put a real person’s name and experience behind your advice. It’s the best-supported tactic in the research, and it’s also just more convincing.
5. Keep your details consistent everywhere. Your name, address, phone number and services should match across your site, Google Business Profile and major directories. Keep earning genuine reviews as well. The research on how much this sways AI answers is thinner, but it’s valuable for local search regardless.
6. Get mentioned elsewhere. Trade associations, local press, suppliers and partner sites all help establish that you’re real and known for what you do. AI tools can’t draw on what nobody has written.
7. Don’t forget Bing. Microsoft Copilot draws on it, and setting up Bing Webmaster Tools only takes a few minutes.

What to skip

• llms.txt files, for now. This is a proposed file that summarizes your site for AI tools. A study of about 300,000 domains found no clear link between having one and getting cited, and Google says you don’t need “AI text files” to appear in its AI features. It’s harmless to add, but not worth paying for.
• Special “AI schema.” Structured data is still useful for regular search, but Google says there’s no special markup needed for its AI features.
• Pages of AI-written filler. If your content says what every other site says, there’s no reason for anyone, human or machine, to cite you.
• Guarantees. Nobody can promise that ChatGPT will recommend you. Ask any GEO vendor exactly what they’ll change and how they’ll report on it.

How to tell if it’s working

• Ask the tools yourself. Once a month, put the questions your customers would ask into ChatGPT, Perplexity, Gemini and Google. Answers vary, so try each one a few times and note the patterns rather than any single result.
• Check your analytics. Visits from sites like chatgpt.com and perplexity.ai show up as referrals. Don’t be surprised if the numbers are small.
• Read Search Console with care. Google counts traffic from AI features in your regular Web search numbers, so a change in clicks won’t tell you on its own whether AI is the reason.
• Ask new customers how they found you. It’s low-tech, but it catches people who saw your name in an AI answer and then searched for you directly, which analytics won’t attribute to AI.

The bottom line

GEO isn’t a replacement for SEO. For most small businesses, it’s SEO done properly, with more attention on being specific, credible and mentioned beyond your own website. Get those right and you’ll be better placed in Google, in AI answers and with the customers reading your site.

AI search is changing quickly, and studies in this area often come from small samples or companies selling related tools. This reflects what’s known as of November 2026.
