Most Facebook ad guides are written by people who never spent their own money on ads. This one is written for people who have.
Last updated: April 2026
Facebook still prints money for ecommerce. Over 3 billion users. The best ad targeting on the planet. And a system that rewards you for making good ads. But here is what nobody tells you. The rules changed. What worked in 2023 does not work now. Broad targeting beats stacked interests. Creative is the new targeting. And if your ads look like ads, they die in the feed. This guide covers everything. From setting up your Business Manager to scaling past $10k a day. No theory. Just what works right now.
Go to business.facebook.com and create a Business Manager account. Add your Facebook Page and ad account. Set up your Meta Pixel on your store using the Conversions API (not just the browser pixel). This matters because iOS privacy changes killed browser-only tracking.
Install the Facebook Conversions API through your Shopify or WooCommerce plugin. It sends purchase data directly from your server. Without this, your ad account is flying blind. Next, verify your domain in Business Manager settings.
This gives you priority for tracking events. Set up your Custom Conversions for Add to Cart, Initiate Checkout, and Purchase. Facebook needs this data to find buyers, not browsers.
Forget complicated campaign structures with 20 ad sets. In 2026, simple wins. Use the Advantage+ Shopping Campaign (ASC) for your main sales driver. It uses machine learning to find buyers across all placements automatically.
For testing new creatives, run a manual CBO campaign with 3-5 ad sets, each with a single ad. Set your budget at the campaign level and let Facebook move money to what works. Kill anything under 1x ROAS after 2 days of spend. Keep anything above 2x ROAS running.
Move winners to your ASC campaign. That is the whole system.
The biggest mistake in 2026 is over-targeting. Facebook is better at finding your buyer than you are. For most ecommerce stores with the pixel installed, go broad. No interests.
No lookalikes. Just age, gender (if relevant), and country. Let the algorithm do the work. If you are brand new with zero pixel data, start with 2-3 broad interest stacks.
Think "Online Shopping" plus your niche. But switch to broad as soon as you get 50 purchases. Lookalikes still work for retargeting campaigns. Build a 1% lookalike from your purchase list and exclude anyone who bought in the last 30 days.
Use this for your mid-funnel campaigns.
Your creative is 80% of your results. Not your targeting. Not your budget. Your creative.
Here is what works: UGC-style videos that look like organic posts. Not polished studio shoots. Real people. Real lighting.
Real reactions. Lead with a hook in the first 3 seconds. "I was skeptical about this until..." or "Stop scrolling if you have [problem]." Show the product in use within the first 5 seconds. Use text overlays because 85% of users watch without sound.
End with a clear call to action. Image ads still work for retargeting. Use lifestyle shots with bold text overlays. Carousel ads work great for showing multiple products or telling a before/after story.
Test 3-5 new creatives every week. The winners pay for the losers.
Start with $50-100 per day for testing. This gives you enough data to make decisions without going broke. Use Campaign Budget Optimization (CBO) so Facebook spreads your budget across ad sets automatically. Do not touch budgets during the learning phase (the first 50 conversions or 7 days).
Every time you change the budget by more than 20%, the learning phase resets. Scale by 20% every 3-4 days when you find a winner. Or duplicate your winning ad set into a new campaign with higher budget. Never scale a cold campaign from $100 to $1000 overnight.
The algorithm panics and your CPMs double.
Scaling is where most people fail. Not because they cannot find winners. But because they cannot make enough variations fast enough. Here is the scaling playbook.
Take your winning creative. Make 5-10 variations. Different hooks. Different thumbnails.
Different text overlays. Same core message. Run each variation in your ASC campaign. The algorithm picks the best ones and scales them automatically.
Add new countries when your home market saturates. Start with tier 1 countries like UK, Canada, Australia. Then move to tier 2. Most stores plateau because they run the same 3 ads for months.
The feed gets bored. Your audience gets bored. Fresh creative every week is the cost of scaling.
