Meta Ads for e-commerce: how to build an account that scales
KJ Marketing Sweden · Updated
A profitable Meta Ads account for e-commerce rests on four things: accurate tracking with the Meta Pixel and the Conversions API, a simple structure with few campaigns, a steady flow of new creative and a scaling plan based on your margin. It's the same foundation we use in every account we run, and it has delivered results up to 35x ROAS.
1. Tracking first
Without accurate data, Meta optimizes for the wrong things. Install the Meta Pixel and the Conversions API so purchases are recorded even when browsers block cookies. Check that the purchase value is sent and that the same purchase isn't counted twice.
2. A simple account structure
Meta needs about 50 conversions per week per ad set to exit the learning phase. That's why fewer, bigger campaigns usually work better than many small ones. A common setup is one main sales campaign, one campaign where new creative is tested and, when needed, one for retargeting.
3. Creative is the new targeting
Since Meta chooses audiences more and more automatically, the ads decide who you reach. Different angles reach different buyers. Make creative in different formats, such as UGC video, static images, carousels and AI variants, and test new hooks every week.
4. Scale on margin, not on gut feeling
Work out the cost per purchase you can afford based on margin and order value. Raise the budget in steps, often 15 to 20 percent at a time, as long as the cost per purchase stays under that limit. Ads that lose impact are replaced with new winners from the test campaign.
5. Watch the right numbers
- ROAS and cost per purchase, compared with your limit.
- Sales in your store, not just in Ads Manager.
- Click-through rate and how many people watch past the first seconds of a video.
- Frequency, which shows when the same people have seen an ad too many times.
An example
In one of our accounts, SEK 150,544 in ad spend delivered 15.2x ROAS. It was built on the same foundation: accurate tracking, a simple structure and new creative every week.
Frequently asked questions
How much should you spend on Meta Ads?
It depends on margin and goals. A budget that brings in a few purchases a day makes it easier for Meta to optimize. We help you work out a starting budget from your cost per purchase.
What's a good ROAS?
It depends on your margin. A store with a high margin can be profitable at 2x, while one with a low margin may need 4x or more. Work out your break-even ROAS first.
Advantage+ or manual campaigns?
For most e-commerce brands, Advantage+ works well as the main campaign, together with a separate campaign for testing new creative. Manual campaigns fit when you need to control something specific.
