Facebook and Instagram ads can bring a small business a steady flow of customers for a few hundred dollars a month. They can also burn through the same money on likes and clicks that never turn into anything. The difference is rarely the ad itself. It's the setup underneath: what the campaign is told to find, whether it can see a sale, and whether the budget can buy enough results to learn from.
This guide covers all of it, in the order you'll need it. Each section links to a deeper guide when you want the detail.
- Set up a business portfolio, an ad account billed to your card, and the Pixel plus the Conversions API before you spend anything.
- Use the Leads or Sales objective. Traffic and Engagement buy clicks and likes, not customers.
- Target broadly within your area, and let the creative do the targeting.
- Keep small budgets in one ad set, and work the budget back from the customers you want.
- Judge on cost per customer over about three months, not on likes, clicks or the first week.
What Facebook ads are good for
Search ads reach people who are already looking. Facebook and Instagram ads reach people who fit your customer, whether or not they're looking today. That makes them strong for anything people buy when reminded: gyms, salons, treatments, home improvement, events, coaching and online stores. They're weaker for emergencies, where people search and buy the same day.
Before you spend, check the numbers work: what a new customer is worth, multiplied by the share of leads that buy, is the most you can pay per lead. Are Facebook ads worth it for a small business walks through it.
Set up the foundations first
Create a business portfolio in your own name
Meta's business portfolio, which used to be called Business Manager, holds your Page, Instagram account, ad account and Pixel. Create it yourself, and add any freelancer or agency as a partner, so you own everything.
Set up an ad account billed to your card
Your spend should go straight to Meta, on your own card, so you can always see exactly what Meta charged.
Connect your Facebook Page and Instagram account
Ads run from your Page and Instagram profile, so make sure both look active and say clearly what you do and where.
Install the Pixel and the Conversions API
The Pixel reports what people do on your website. The Conversions API sends the same events from your server, which catches what browsers and ad blockers miss. Test both before launch in Events Manager.
Decide what counts as a result
A lead, a booking or a purchase. Set that event up and check it fires once per result. It's what the campaign will learn from.
Pick the right objective
Meta offers six campaign objectives, and the one you pick tells Meta who to find. Pick the wrong one and it will find exactly the wrong people, cheaply.
| Objective | What Meta looks for | Use it when |
|---|---|---|
| Awareness | People likely to remember the ad | Rarely first for a small business |
| Traffic | People likely to click | You only want visits, which is seldom the goal |
| Engagement | Likes, comments, video views and messages | You want conversations in Messenger, Instagram or WhatsApp |
| Leads | People likely to fill in a form, call or message | Most local service businesses |
| App promotion | Installs and in-app actions | You have an app |
| Sales | People likely to buy or book on your site | Online stores and website bookings, once tracking works |
This is the most common setup mistake we see. One climbing gym we manage started at £28.82 per booking on a link click objective, and reached £5.13 once purchase tracking and a sales objective were in place, on essentially the same budget.
Targeting in 2026: broad, with guardrails
Meta's Advantage+ audience now treats most targeting as a suggestion. Location, minimum age, language and audience exclusions are hard limits. Age ranges, gender, interests and lookalike audiences are hints that Meta can go beyond when it expects better results.
For a small business, that means getting the hard limits right, especially the area you serve, and letting the ad's words and pictures attract the right people. If you advertise housing, jobs, or financial products and services, your ads fall into a special ad category with stricter targeting rules in the US, Canada and parts of Europe, so select it when you create the campaign.
Creative does most of the work
With broad targeting, the ad itself decides who stops scrolling. In the first line or the first three seconds, say who it's for, what they get and why now. Real photos and short videos of your work, your space or your customers usually beat stock images. Mix formats: single images, carousels and short vertical video for Reels and Stories.
Then keep new ads coming. Ads wear out as the same people see them again, and an account that leans on one ad drops when that ad fades. On one climbing gym we manage, we tested 118 creatives across 34 campaigns in ten months, on daily budgets between £5 and £15. Our creative testing guide shows how.
Lead forms or a landing page?
Instant forms collect details without leaving Facebook or Instagram. They usually bring more leads at a lower cost, and more of them are low intent. A landing page usually brings fewer, more serious enquiries, and gives you full tracking. If form leads don't pick up the phone, switch to the "higher intent" form type or test a landing page built for the ad.
Either way, connect form leads to your email or CRM. Meta only lets you download lead data for 90 days, and leads that wait a day go cold. If leads aren't arriving at all, work through nine checks for Facebook ads that aren't getting leads.
How much to spend
Work it back from the customers you want: new customers wanted, divided by the share of leads that buy, multiplied by what a lead costs. LocalIQ's 2026 benchmarks put the average cost per lead at $27.39 across industries, so $500 a month buys about 18 leads at the average. Keep a small budget in one ad set: Meta looks for about 50 results a week per ad set to finish learning, and splitting the budget only slows that down.
How much to spend on Facebook ads has a calculator that does the sum with your own numbers.
Measure what matters
| Number | What it tells you |
|---|---|
| Cost per lead | Whether the ads and the offer attract enquiries at a sensible price |
| Leads that become customers | Whether the leads are the right people, and whether follow-up works |
| Cost per customer | The number to judge everything on, against what a customer is worth |
| ROAS (online stores) | Revenue per dollar of ad spend, judged against your break-even |
| Frequency and click-through rate | Early warnings that creative is wearing out |
Two cautions on the numbers. Ads Manager credits each sale to the day of the ad, so the last week always looks worse than it will end up. And since March 2026, Meta only counts link clicks as click-through, so reported results can fall with no real change. Why ROAS drops when nothing changed covers both, and what is a good ROAS for Facebook ads sets your target.
The mistakes that cost the most
- Boosting posts and calling it advertising. A boost buys engagement, not customers.
- Running a Traffic or Engagement campaign when you want leads or sales.
- Splitting a small budget across many ad sets that never learn.
- Judging after three days, or doubling the budget the moment something works. See why ROAS drops when you increase budget.
- Letting leads wait. A lead answered tomorrow is often a lead lost.
- Letting an agency own your ad account or your Pixel.
Do it yourself or get help?
On a budget of a few hundred dollars a month, running a simple campaign yourself is often the right first step: one objective, one ad set, a handful of ads, and a weekly look at the numbers. Bring in help when the ads have shown they can pay back and you want them to scale, or when results have stalled and you can't see why.

Questions people ask
Do Facebook ads work for small businesses?
Yes, for many of them: local services, online stores, gyms, clinics, events and coaches especially. They work when a customer is worth clearly more than it costs to win one, the campaign is set up for leads or sales rather than clicks, and someone follows up quickly.
How much do Facebook ads cost for a small business?
LocalIQ's 2026 benchmarks put the average cost per lead at $27.39 across industries, from about $12 to $62 depending on the industry. Work your budget back from the customers you want: customers wanted, divided by the share of leads that buy, multiplied by cost per lead.
Which campaign objective should a small business use?
Leads if you want enquiries, calls or bookings through a form, and Sales if people buy or book on your website and the Pixel can see it. Traffic and Engagement find people who click and like, which is rarely what a small business needs.
Are boosted posts the same as Facebook ads?
A boost is a simplified ad with fewer settings, usually optimized for engagement. It can help a post reach more people, but it's a poor way to get leads or sales. Ads Manager gives you the objective, audience controls and tracking that a boost leaves out.
How long do Facebook ads take to work?
In our accounts, first leads typically land in 10-14 days, with a reliable cost per lead by around day 45. Judge results on cost per customer over about three months, not on the first week.
Do I need a website to run Facebook ads?
Not strictly. Instant forms collect leads inside Facebook and Instagram. A website with the Pixel and the Conversions API gives you better tracking, a place to send people who want more detail, and a way to optimize for bookings or purchases.
Should I hire an agency or run Facebook ads myself?
On a small budget, running a simple campaign yourself first usually makes sense. Bring in help when the ads have shown they can pay back and you want them to scale. We charge $500-$2,000 a month, month-to-month, and we're not the right fit if your offer hasn't sold yet without ads.
