How to Advertise on Facebook: Set Up Your First Campaign Step by Step
Running Facebook ads looks like a few clicks, but the setup decides the outcome. A step-by-step campaign setup from business portfolio to first-week optimisation, plus the mistakes to avoid.
Advertising on Facebook means setting up a business portfolio and ad account, installing the Pixel for measurement, choosing the right campaign objective, defining audience and budget, and publishing the ad. Ads are managed in Meta Ads Manager, and the same campaign can also run on Instagram, Messenger and the Audience Network.
This guide walks you through building your first campaign from scratch, what to look at during the first week after launch and the mistakes that burn the most budget.
Before you start: account structure
Having your assets organised before you advertise is half the work. You need:
- A Facebook Page — ads run on behalf of a Page; keep the profile picture and description up to date.
- A business portfolio (Business Manager) — brings the Page, ad account, Pixel and Instagram account together and manages team permissions.
- An ad account — currency and time zone cannot be changed later, so pick them correctly.
- A payment method — add a card or another supported method to the ad account.
- An Instagram account — connect it to the portfolio if you want to appear on Instagram as well.
Measurement: Pixel and Conversions API
Advertising without measurement is like driving blindfolded. The Meta Pixel records events on your site such as page views, add-to-cart and purchases; the Conversions API sends the same events from your server and reduces data loss caused by browser blocking. If your goal is sales or leads, finish this setup before launching. See our guide to Meta Pixel and Conversions API setup for the steps.
Understanding campaign structure
Everything in Ads Manager has three layers:
| Layer | What you set | Example |
|---|---|---|
| Campaign | Objective (what you want) | Sales, leads, traffic |
| Ad set | Audience, budget, schedule, placements, optimisation | London, age 25–45, daily budget |
| Ad | Image or video, copy, link, call-to-action button | Product video + "Shop Now" |
Choosing the right campaign objective
Meta groups objectives into six: awareness, traffic, engagement, leads, app promotion and sales. The objective tells the algorithm whom to show your ad to. If you want sales, choosing "traffic" brings cheap clicks but not the people most likely to buy.
- Sales — e-commerce and online sales; requires a purchase event in the Pixel.
- Leads — service businesses collecting enquiries through forms, Messenger or WhatsApp.
- Engagement — campaigns aiming for messages, video views or Page engagement.
- Awareness — broad reach for a new brand or regional awareness.
Setting up your first campaign step by step
- Create a campaign — click "Create" in Ads Manager and pick the objective that matches your goal.
- Set the conversion location — website, form, messages or app; for sales, choose the Pixel event.
- Set the budget — a daily budget is easier to manage at first; give the test a few days.
- Define the audience — start with location, age and language; do not over-narrow interests, leave the algorithm room.
- Choose placements — automatic (Advantage+) placements are usually a good start for beginners.
- Prepare the ad — image or video in vertical and square formats, short clear copy, a fitting button.
- Preview and publish — check how it looks in different placements, then submit for review.
How to write ad copy
The visual grabs attention; the copy persuades. In Facebook ads the first line matters most, because long text is cut off with "See more" and most people only read the first sentence. Use the first line for the customer's problem or your product's strongest benefit. Then add a trust element in a sentence or two: delivery time, return guarantee, a customer review or a warranty. Finally, say clearly what to do next. Avoid exaggerated promises and unverifiable claims such as "the best" or "guaranteed results"; they cost trust and can cause problems in policy review. Testing two different texts with the same visual quickly shows which message resonates with your audience.
How much budget do you need?
The right budget depends on your product price, margin and target cost per conversion. As a rule of thumb, an ad set needs enough conversions per week for the algorithm to learn, so the budget should be several times your target cost per conversion. For the calculation method, see how to set an advertising budget.
The first week after launch
- Let the learning phase run — results fluctuate in the first days; daily changes reset learning.
- Watch the right metric — not likes, but cost per result, click-through rate and conversion rate.
- Compare creatives — pause the clearly weak one, keep the winner running.
- Verify measurement — check in Events Manager that events arrive correctly.
Reading results: key metrics
| Metric | What it tells you | When to pay attention |
|---|---|---|
| Cost per result | What you pay for a sale, lead or message | When it is clearly above your target |
| Click-through rate (CTR) | How many viewers click | Low CTR suggests creative or audience mismatch |
| Conversion rate | How many clickers complete the action | Low rate points to the landing page |
| Frequency | How often one person sees the ad on average | Rising frequency signals creative fatigue |
| ROAS | Revenue per unit of ad spend | The main profitability signal in e-commerce |
Read metrics together, not in isolation: a high CTR with a low conversion rate means the ad attracts interest but the page does not convince.
The most common mistakes
- Choosing the wrong objective — running traffic or engagement campaigns when you want sales.
- Starting without measurement — spending budget before installing the Pixel.
- Over-narrowing the audience — very small audiences drive costs up quickly.
- Deciding too early — shutting down a campaign after one day of data.
- Relying on one creative — performance drops when ad fatigue sets in, so keep spare creatives ready.
Manage it yourself or hand it to experts?
Starting on your own with a small budget is a sensible way to test and learn. Once the budget grows, you sell several products or markets, or results stall, a management service that runs creative production, measurement and continuous testing in one team saves both time and budget.
