Comparison by OMOSA, an eCommerce agency for fashion and lifestyle brands and a Google partner. We included ourselves, ranked first for a specific niche, and we explain our criteria. Information about the other agencies comes from their own websites, gathered on October 23, 2026. The Google badges mentioned are the ones the agencies display themselves.
On Google, an eCommerce brand sells mainly through Shopping and Performance Max, which depend on the quality of your product feed. A good Google Ads agency knows how to optimize that feed, and measures results against your actual sales, not just the ROAS Google reports.

How did we choose these agencies?
An agency is included in this comparison if it meets three conditions:
- it manages Google Ads for eCommerce brands;
- it presents its services and clients on its website;
- it appears in the Google Ads agency comparisons that AI assistants cite, or in searches about Google Shopping.
We don’t give ratings: we haven’t worked with these agencies. We say which brand each one seems best suited to, based on how it presents itself.

Frequently asked questions
Google Ads or Meta Ads for an eCommerce brand?
Both, with different roles. Meta creates demand by showing your products to people who were not looking for them. Google captures existing demand, through searches and Shopping. A fashion brand usually needs both, with a budget split decided from margin and new customers, not from the ROAS each platform claims.
What does the Google Premier Partner status mean?
Google gives it to the best ranked agencies of its partner programme in each country. It shows experience and a large volume of campaigns managed. It does not tell you whether the agency knows eCommerce or your sector: ask for case studies from brands like yours, with results and their period.
Why does the product feed matter so much on Google Shopping?
On Shopping and Performance Max, Google builds your ads from your product feed: titles, images, prices, availability. A poorly written feed means badly matched searches and ads that do not show. Ask your agency how it reviews and improves your feed before touching the bids.
Why does my product feed impact my Google and Meta ads?
The feed powers Google Shopping and Meta's dynamic carousels. If it's dirty (bad titles, empty categories, out-of-stock products still active), you burn budget and Google delivers you less because it rates your quality as poor. In fashion with tons of variants, it's a critical piece of work.
How much does it cost?
Each offer is a fixed monthly fee, with no variable part. Attract, paid media: from €2,500 per month. Activate, eCommerce: from €3,350 per month. Retain, CRM: from €3,350 per month. The audit of the three areas: from €3,000, once.
What is the minimum commitment?
Three months, renewable by quarter, with 30 days’ notice. Three months is one full steering cycle: long enough to measure, short enough to correct.
