LLM SEO is the practice of making your business easy for AI assistants like ChatGPT, Gemini, Claude, and Perplexity to find, trust, and mention when someone asks for a recommendation. "LLM" stands for large language model, the technology behind those assistants. For a small business, LLM SEO comes down to three habits: state clear facts about what you do, keep those facts the same everywhere you're listed, and get other trustworthy websites and real customers talking about you. It's mostly good old SEO with a different finish line: instead of a blue link, you're aiming to be the name the AI repeats.
TL;DR
LLM SEO means shaping what AI assistants can read about your business so they're more likely to mention you. AI tools either search the web on the spot or lean on what they learned in training, and either way they can only repeat what's written publicly. The businesses that get mentioned tend to have specific, quotable facts on their site and profiles, consistent details across directories, reviews that describe real specifics, and mentions on other websites. Nobody can guarantee an AI will recommend you, and anyone selling "guaranteed ChatGPT rankings" is guessing. If you want a step-by-step version you can do with ChatGPT or Claude, the free AI SEO course walks through it, no website required.
What LLM SEO actually means
You'll see a pile of acronyms for this: LLM SEO, GEO (generative engine optimization), AEO (answer engine optimization), AI search optimization. They all describe the same shift. People used to type "plumber near me" and scan ten links. More of them now ask a full question, like "Who's a reliable plumber in Dayton who does same-day water heater replacements?", and read a single written answer.
That answer might come from:
- ChatGPT, Gemini, Claude, Copilot, or Perplexity, chatting with the customer directly
- Google's AI Overviews, the summary that sits above the regular results
- Voice assistants that read one answer out loud
Classic SEO tries to get your page into the list. LLM SEO tries to get your business into the sentence.
How AI assistants decide who to mention
There's no published rulebook, and the tools change often. But the basic mechanics are well understood, and they explain what to do.
When someone asks an AI assistant for a recommendation, it usually does one or both of these:
- Searches the web right then. ChatGPT search, Perplexity, Gemini, and Google's AI Overviews all pull live pages, listings, and reviews, read the top ones, and summarize them.
- Draws on its training. The model learned from a large snapshot of the public web, which can be months or years old.
Either way, the AI can only work with what's written down publicly. If the fact that you offer weekend service at no extra charge lives only in your head, no AI can repeat it. If it's stated plainly on your profile, your website, and in three reviews, you've given it something to work with.
The signals that tend to matter
| Signal | What it looks like for a small business |
|---|---|
| Clear, specific facts | "We replace most water heaters the same day you call" instead of "We pride ourselves on fast service" |
| Consistency | Same name, address, phone, hours, and services on Google, Bing, Yelp, Facebook, and your site |
| Descriptive reviews | Customers mentioning the actual job, neighborhood, and what stood out |
| Mentions elsewhere | Local news, "best of" lists, your chamber of commerce, supplier and partner pages, industry directories |
| Direct answers | A short FAQ that answers the questions customers really ask |
Notice that none of these are tricks. They're the same things that help you on Google and with word of mouth. That's the honest truth about LLM SEO: the shortcuts don't exist, but the fundamentals work on every platform at once.
LLM SEO vs. regular SEO
| Regular SEO | LLM SEO | |
|---|---|---|
| The goal | Rank your page in a list of links | Get your business named in a written answer |
| What the customer sees | Ten results, a map pack, ads | One answer, maybe three to five names |
| Biggest lever | Your own pages and Google Business Profile | What other sources say about you, plus clear facts |
| Keywords | Short phrases ("roofer Tulsa") | Full questions ("roofer in Tulsa who handles insurance claims") |
| How you measure | Rankings, clicks, calls | Asking the AI the questions your customers ask, month after month |
The overlap is big. Most of the work you'd do for one helps the other. The difference is emphasis: AI answers lean harder on third-party mentions and specific, quotable details, because the AI is trying to sound confident about who to recommend.
A practical LLM SEO plan for a small business
You don't need a developer or an agency for any of this. You need a free afternoon and an AI assistant to help with the writing.
1. Write a fact sheet
List 15 to 25 short, true statements about your business. Each one should stand on its own, so an AI could quote it word for word:
- What you do and where you do it
- Who you serve (and who you don't)
- Services and typical price ranges, if you're comfortable sharing them
- The thing you do that competitors don't, stated precisely
- Licenses, certifications, years in business, languages spoken, hours
Here's a prompt you can paste into ChatGPT or Claude:
I own [business] in [city]. Here's everything I know about it:
[paste your services, hours, history, what customers praise, what makes you different]
Write 20 short, specific, true statements about my business that an AI
assistant could quote directly. One fact per sentence. No marketing fluff.
Don't add anything I didn't tell you. Flag anything that sounds like a claim
I'd need to back up.Then put those facts to work: on your website if you have one, in your Google Business Profile description, in your Bing Places and Yelp listings, and in your social bios.
2. Add a short FAQ
Turn your fact sheet into 8 to 12 questions and answers, each starting with the direct answer. "Do you charge extra on weekends? No. Weekend and evening calls cost the same as weekday calls." AI tools pull plainly worded answers far more easily than paragraphs of brand language. No website? Use the Q&A and post features in your Google profile, and the "About" sections on every listing you have.
3. Make your details match everywhere
Search your business name and check every listing you can find: Google, Bing, Apple Maps, Yelp, Facebook, Nextdoor, industry directories. Fix old phone numbers, old addresses, and services you no longer offer. When sources disagree, an AI has less reason to be confident about you.
4. Ask for reviews that describe the job
"Great service!" doesn't tell an AI anything. "They fixed our furnace on Christmas Eve and didn't charge a holiday rate" does. You can't script reviews, and you should never write fake ones, but you can ask happy customers a simple question when you request a review: "If you mention what we did for you, it really helps other people find us."
5. Get mentioned on other websites
This is where most AI visibility is won, and it's the part most owners skip. Good targets:
- Industry and certification directories for your trade
- Local news and "best of" lists, which often take tips from businesses with a real story
- Your chamber of commerce and neighborhood business groups
- Suppliers and partners with "where to buy" or "find a pro" pages
- Community spaces like Nextdoor, local Facebook groups, and Reddit, where you answer questions honestly and say you own the business
One rule: be a real participant. Fake recommendations in community threads get spotted fast and backfire.
6. Test it once a month
Write down 8 to 10 questions your customers would actually ask an AI, like "best [service] in [city]" or a question about the thing you do best. Once a month, ask them in ChatGPT, Gemini, and Google, ideally in a private browser window, and note who gets mentioned. Answers vary from one try to the next, so look for trends over months, not one result.
What doesn't work (and what to be skeptical of)
LLM SEO attracts a lot of hype. Some things to avoid:
- Guaranteed AI rankings. No one controls what ChatGPT or Gemini says. A vendor promising a spot is selling something they can't deliver.
- Pages stuffed "for AI." Hidden text, keyword lists, or dozens of near-identical pages don't help and can hurt you with Google.
- Fake reviews or astroturfed posts. They violate platform rules, and they poison the very signals you're trying to build.
- Paid spammy directory links. A handful of trusted, relevant listings beats hundreds of junk ones.
- Obsessing over technical files. You may hear about files like
llms.txt. They're harmless, but there's no public confirmation that the major assistants rely on them, and they won't move the needle for a local business the way reviews and mentions will.
Where AI gets it wrong about your business
Even when AI mentions you, it can get details wrong: old hours, a service you dropped, a price from years ago, or another business's reviews mixed into yours. AI assistants don't always have live data, and they sometimes fill gaps with confident guesses.
That's another reason the monthly test matters. When you spot a wrong detail, trace it back. Usually there's an outdated listing or old page somewhere saying it. Fix the source, and the answer tends to follow over time.
The same caution applies when you use AI to help with your LLM SEO work. If ChatGPT drafts your fact sheet, read every line. It will happily invent a "family-owned since 1985" if you let it.
Frequently asked questions
What is LLM SEO?
LLM SEO is the work of making your business easy for AI assistants such as ChatGPT, Gemini, Claude, and Perplexity to find, trust, and mention in their answers. It focuses on clear facts, consistent listings, descriptive reviews, and mentions on other websites.
Is LLM SEO different from regular SEO?
Mostly it's the same foundation with a different emphasis. Regular SEO aims to rank a page in a list of links, while LLM SEO aims to get your business named in a written answer, which leans harder on third-party mentions and specific, quotable facts.
Do I need a website for LLM SEO?
No. A complete Google Business Profile, accurate listings on Bing, Yelp, and industry directories, good reviews, and mentions on other sites can all get you into AI answers. A simple website helps, but it isn't required to start.
Can I pay to get my business recommended by ChatGPT?
Not in the answers themselves. Paid ads, where they appear, are labeled separately from the answer, and no agency can guarantee your business gets mentioned. Be skeptical of anyone promising one.
How do I know if LLM SEO is working?
Ask AI assistants the questions your customers would ask, once a month, and write down who gets mentioned. Answers vary from try to try, so track the trend over several months instead of reacting to a single result.
