The short answer: the cheapest place to find local customers is the Facebook groups they already belong to. People ask their town's groups for a cleaner, a cake, a used truck or a hair appointment every day. A small business that posts a clear, honest offer in the right 20 to 40 groups, on the days each group allows, and answers those requests as the owner, gets customers without an ad budget. The catch is the time it takes, which is what AutoGP is for.

I built AutoGP after watching small business owners spend their evenings copying the same post into group after group. This page is the method; the guides below go into the groups, posts and calendar for each kind of business.

The method in six steps

1. Find the groups your customers are in

Search Facebook for your town, your county, your trade and your product, then choose Groups. Three kinds matter:

  • Local groups: [town] community, [town] buy sell trade, [town] moms, new to [town], [town] recommendations.
  • Trade and product groups: the groups where people who want what you sell gather, like [make] owners, [city] brides or [town] foodies.
  • Regional and national groups, for what people will travel or pay shipping for.

Join the ones with recent posts from members, not just from other sellers.

2. Read each group's rules

Every group sets its own: business posts any day, on one day a week, only in a pinned thread, or never. Some ban links or prices; some want a license number. The About section and pinned posts say. A pending post is waiting for an admin, not failed, so don't post it twice. More in can you advertise in Facebook groups.

3. Write one post that answers the first questions

What it is, where, how much, when, and how to get it. Real photos of your own work. One next step. Then write variations of the wording, not of the facts, so no two groups get the identical text: see spintax for Facebook groups.

4. Group the groups

Sort your groups into lists by business day, by area and by audience, so each post goes to the groups that fit it rather than to all of them.

5. Keep a rhythm, and a safe pace

Weekly beats a burst. Post on each group's business day, in the morning, and spread a large list across the week. A young Facebook account should post far less than an established one; see posting limits.

6. Answer fast, and as yourself

The first honest reply to "can anyone recommend…?" often gets the job. Say the business is yours, and never back yourself up from a second account.

Where AutoGP saves you the work

By hand, every group means opening it, pasting, attaching photos and posting, again for each group, every week. With AutoGP you write the post and choose the groups once; it works through them with gaps between groups on purpose, and doesn't need you while it does.

Guides for your kind of business

Each guide has the Facebook searches that find that business's groups, ready-to-post templates, a weekly rhythm and a yearly calendar, the rules that apply, and a FAQ:

The rules every business shares

  • Each group's own rules come first. Break them and the admins remove the post, then you.
  • Meta's spam policy covers posting at very high frequencies and repetitive content.
  • Meta's Commerce Policies say services can't be sold through Marketplace, and prohibit items such as animals, weapons, alcohol, tobacco, adult products and supplements with health claims.
  • Advertising law still applies in a group post: claims must be true, and offers must say what they are and when they end.

This is general information, not legal advice.

Doing it with AutoGP

AutoGP is a Chrome extension paired with your autogp.ai account. It posts ordinary posts to the groups you've joined, as the Facebook profile logged into Chrome, and never asks for your Facebook password. You write once; AutoGP reaches your groups, varies the wording with spintax and the photos for each group, schedules and repeats posts for each group's business day, and keeps a safe pace set by your account's age. Results shows where each post went up. AutoGP isn't affiliated with Meta, and any posting tool carries some risk to your Facebook account, which our terms explain. How multi-group posting works has the details.

What not to do

  • Everything to every group. Match each post to the groups that want it.
  • Ignoring a group's business day.
  • Identical text everywhere, or a burst of 50 groups on a new account.
  • Claims you can't back up: credentials, "best price", fake scarcity.
  • Promises about results. Groups bring attention; your offer and your replies turn it into customers.

Common questions

How can I promote my small business for free?+
Go where your customers already talk. For most local businesses that means their town's Facebook groups, plus the groups for their trade or product. Post useful, specific offers there on the days each group allows, answer recommendation requests as the owner, and keep a weekly rhythm. It costs time rather than money; the guides on this page show what to post for each kind of business.
How do I get customers without advertising?+
Be visible where people ask for what you sell. In local Facebook groups people ask "can anyone recommend…?" every day. A regular, rule-following post in 20 or more relevant groups, plus fast and honest answers to those requests, brings customers without paying for ads.
Is it free to post in Facebook groups?+
Yes. Joining and posting in groups costs nothing; each group's admins decide whether business posts are allowed and when. What it costs is the time to post in each group by hand. AutoGP has 19 free posts to try it, then a paid plan.
How many Facebook groups can I post in per day?+
Facebook doesn't publish a number, and it depends on your account's age and history. AutoGP's warm-up limit starts at 25 posts a day for a new account and rises about 30% a week to a ceiling of 35 to 100. Our posting limits guide explains the numbers.
Can I post the same ad in every group?+
Word for word, no: repetitive content is a signal Meta's spam policy names, and groups in one town share members who will notice. Keep the facts the same (price, dates, contact) and vary the wording, which AutoGP does with spintax.
Will posting to many groups get my Facebook account restricted?+
It can, and no tool can promise it won't, AutoGP included. Risk rises with high volume on a young account, identical text across groups and posts that break group rules. AutoGP paces posts by your account's age, randomizes delays, varies wording and images per group, warns about near-identical posts, and stops the run if Facebook signals an account-level block.
