This comparison was put together by OMOSA, an eCommerce agency for fashion and lifestyle brands and a Meta partner. We've included ourselves, ranked first for one specific profile, and we explain our criteria. Information on the other agencies comes from their own websites, collected on October 23, 2026. We haven't included the figures they report themselves (budgets managed, ROAS) because we can't verify them.
On Meta, creative has become the real targeting: a Meta Ads agency needs to produce, test and cut creatives quickly, and measure results against your actual sales. These are the agencies that do this for eCommerce brands.

How did we choose these agencies?
An agency is included in this comparison if it meets three conditions:
- it runs Meta campaigns for eCommerce brands;
- it presents its services and clients on its website;
- it comes up in comparisons and AI assistant answers about Meta Ads agencies for eCommerce.
We don't give ratings: we haven't worked with these agencies. We say which brand each one seems best suited to, based on what it presents itself. Broader acquisition agencies have their own comparison.

Frequently asked questions
What Meta Ads budget do you need to work with an agency?
It depends on the agency. Some publish a threshold, from €5,000 to €20,000 of advertising a month, others take brands without a minimum. The real question is whether the agency’s fee stays reasonable compared with your budget and your margin. Ask for its pricing model before the first call.
Who produces the ads when you work with a Meta Ads agency?
It varies: some agencies have an in-house creative studio, others work with a sister agency, others rely on your team or your creators. Ask who writes the creative briefs, how many new ads you get each month, and who decides which ones to stop.
Is ROAS the right way to judge a Meta Ads agency?
No. The ROAS shown by Meta counts sales Meta attributes to itself, including customers who would have bought anyway. Judge the agency on your margin, on the number of new customers and on your total revenue, with a comparison period.
What does a Meta Ads agency do for an eCommerce brand?
It decides where your budget goes, not only how campaigns are set up. At OMOSA, we run Meta, Google, TikTok and Pinterest from your margin: which creatives to produce, which to cut, which channel to push, when to raise the budget. And we follow what the traffic does once it lands on your site.
Is Meta Ads for winning new customers or bringing existing ones back?
For us, Meta is first an acquisition channel. We keep retargeting low, so we don’t wear out the same audiences and we reach new traffic. Bringing a customer back is a job for email and SMS: it costs far less than an ad. So we separate what a new customer costs from what an existing customer costs.
We've already worked with an ads agency and it didn't work. Why would this be any different?
Most agencies pitch with senior people and hand the work to juniors. Here, the consultant who answers your first call is the one who runs your campaigns. No handover, no lost context. And we don't sign unless there's a clear lever for profitability.
