Is a Facebook page enough for a small business? What Google and AI can see

A Facebook page is enough for keeping in touch with customers who already know you. If new customers should find you through Google or an AI assistant, Facebook on its own is not enough. In our test of Gemini answers about local services, Facebook was a cited source in 1 of 111 answers, while business directories were cited in 70.

Plenty of small businesses use Facebook as their only home online. It is free, easy to update from a phone, and customers send messages there. This article explains why that falls short for AI search, and what to add without spending much.

What Facebook lets AI crawlers read

Facebook's robots.txt tells the crawlers of AI companies to stay out of the whole site. Robots.txt is a public file in which a website tells bots where they may and may not go. We read facebook.com's file on 4 November 2026. It blocks these by name:

• GPTBot (OpenAI),
• ClaudeBot (Anthropic),
• PerplexityBot (Perplexity),
• Google-Extended (Gemini).

Any crawler that the file does not name falls under a final rule that blocks everything. That includes OAI-SearchBot, which OpenAI describes in its crawler documentation as the bot used to surface websites in ChatGPT's search features.

Google-Extended deserves a note. Google's crawler documentation says this token controls whether a site's content may be used to train Gemini models and for grounding, where Gemini draws on Google Search results while it answers. It does not affect inclusion in Google Search.

Facebook does let Google's and Bing's regular crawlers into public pages, so your page can appear in Google results. For AI assistants, much of it is closed, and a lot of content only shows to people who are signed in.

What our test showed: Facebook in 1 of 111 answers

When we checked where an AI assistant gets its information about local businesses, Facebook barely appeared. On 30 October 2026 we asked Gemini 3.8 Flash with Google Search, through the API, 72 questions about businesses in Slovak towns, each three times, 216 answers in total. For every answer we recorded the domains Gemini listed as sources.

Source	Answers citing it (local services, 111 answers)
At least one general business directory	70
azet.sk (Slovak directory)	45
zoznam.sk (Slovak directory)	33
facebook.com	1

For guesthouses and hotels (105 answers), Facebook was not a source at all. Booking portals dominated there, with booking.com in 48 answers.

How to read this: it is one assistant on one day, in one country, and we see domains, not individual pages. The directories will differ where you are. The pattern is what matters: when AI looked up local businesses, it went to directories, booking portals and business websites, and almost never to Facebook. Why AI names some businesses and not others is covered in why AI assistants mention competitors, not you.

When a Facebook page really is enough

A Facebook page alone is fine for a business that does not need new customers from search. Typical cases:

• your calendar is full from regulars and word of mouth,
• you sell mainly to people who already follow you, such as home baking for the neighbourhood or a seasonal stall,
• you only use Facebook for announcements like changed opening hours or holidays.

If customers often tell you they found you on Google or that an AI suggested you, or you want more of those customers, the steps below are worth the hour they take. What decides it is where new customers should come from, not the size of the business.

Common mistakes when a business only has Facebook

The most common mistake is that the details on Facebook do not match the details elsewhere online. When Facebook shows one phone number, a directory another and the map a third address, neither a search engine nor an AI assistant knows which is right.

• Opening hours only in a post. You post new hours but the page info still shows the old ones. Update both, and your Google Business Profile too.
• No town and no service. The page description has a slogan but not what you do and where. Write it plainly, for example “Air conditioning installation and service, Leeds and surrounding area”.
• Links to nowhere. If your website moves or closes, old links in directories and on Facebook lead to an error. Click through them twice a year.
• Reviews only on Facebook. Facebook recommendations are mostly visible to signed-in users. Ask happy customers for a Google review too, which anyone can see.

What to add so new customers can find you

The cheapest route is to keep Facebook and add three things that are free or close to it.

1. A Google Business Profile. It is free, and it is what Google uses to build the map in local results. Fill in the category, opening hours, photos and a link.
2. Directory listings. A basic listing is usually free. Use the same name, address and phone number as on Google, and link to your website, or to Facebook until you have one.
3. A simple website. One page is enough: what you do, in which town, with prices or at least a rough range, contact details and opening hours. If you offer several services, add a page for each later.

Facebook then does what it is good at: news, photos of your work and messages with customers. Link to your website from your page info, and to Facebook from your website.

How to check where AI gets information in your field

The quickest check is to ask the way a customer would. Type “Can you recommend a plumber in Leeds?” into ChatGPT or Gemini, with your own trade and town, and look at the links under the answer. You will see which directories and websites keep coming up, and those are the places where your details should be correct. Step by step, this is in how to check if ChatGPT recommends your business.

One answer proves little. In the same test, only 36 % of the businesses AI named appeared in all three runs of the same question. If you would rather not repeat the questions by hand, the AI visibility test on Zmienka asks them for you, three times each, and shows which sources AI used.

Frequently asked questions

Do I need a website if I have a Facebook page?

If new customers look for you through Google or an AI assistant, a simple website, a complete Google Business Profile and accurate directory listings help more than Facebook alone. A one-page website is a fine start.

Can ChatGPT see my Facebook page?

Facebook's robots.txt blocks OpenAI's GPTBot by name, and its catch-all rule also covers OAI-SearchBot, the crawler OpenAI uses for ChatGPT search (checked on 4 Nov 2026). We have not measured ChatGPT answers directly.

Will Google show my Facebook page in search results?

It can. Facebook does not block Google's regular crawler from public pages. For local searches such as “plumber near me”, though, Google mostly shows the map with Business Profiles.

Is Instagram better than Facebook for this?

Both belong to Meta and are built mainly for signed-in users. For new customers coming from search and AI assistants, a website, a Google Business Profile and directories carry more weight.
