Selling own brands and third-party brands requires two different strategies: the own brand gives margin and control but must build demand; third-party brands have existing demand but lower margins and more competition. Mixing them in the same campaign hides what each is worth.
The essentials in a definition
Selling own brands and third-party brands requires two advertising strategies: for third-party brands, brand demand already exists and competition (including the manufacturer) is strong; for own brands, demand and trust must be built. Margin, product control and differentiation change priorities. Merchant Center and measurement of key events help separate results, and the Unfair Commercial Practices Directive frames claims.
Two logics
Own brand: you have to create awareness and trust, but there is margin and exclusivity, and it is possible to build lasting assets (brand, customers, data). Third-party brands: demand already exists (people search for the brand), competition is direct and margin is generally lower.
Each calls for distinct budgets, messages and targets.
Campaigns for third parties
Search by brand name is very competitive: the manufacturer, other resellers and comparison sites contend. You compete on price, delivery, service and availability. Shopping and the feed are central. Track prices and stock. In many cases margin only allows high return targets.
Consider the value of the supplier relationship (support, co-funding).
Two strategies: own brand and third-party
- Separate campaigns and reports by type of brand
- Third-party: compete on price, delivery and service
- Own brand: build demand and proof
- Review the mix every quarter
Campaigns for the own brand
Invest in discovery, content, proof, reviews and remarketing, to create demand. Protect brand search. Measure new customers and repeat purchase. Accept a lower initial return if customer value over time compensates. Use the higher margin to support acquisition costs.
Use the own brand as an anchor for price and value.
Selling what belongs to others gives volume; selling what is yours gives a future.
Balancing
Separate campaigns, budgets and reports by type of brand. Avoid third-party brands “eating” budget because they give immediate return, while the own brand, which grows in the long term, is cut. Define each one’s role in the portfolio. Review the mix every quarter.
Protect the assets that are yours.
Decision table
| Aspect | Third-party brand | Own brand |
|---|---|---|
| Demand | Already exists, often by brand | Needs to be created |
| Margin | More limited and price-pressured | Usually higher, with more control |
| Differentiation | Service, price, delivery, selection | Product, story, quality |
| Risk | Direct price comparison | Lower awareness and trust |
Common mistakes to avoid
- Competing only on price with third parties. Margin vanishes and the advantage is fleeting.
- Spending on own brand without proof. Without reviews and trust, conversion is low.
- Mixing everything in one campaign. Objectives and margins are different.
How to measure the result
Compare contribution margin, cost per new customer and retention between the two structures, not just return on ad spend.
Limits and exceptions
Each category and market has its own dynamics, and dependence on external suppliers can change price and availability terms. Building an own brand takes time and capital, and results are not immediate. Reassess the mix periodically.
Illustrative example
Illustrative example: a cosmetics store separates campaigns into two structures. For third-party brands, it highlights fast delivery and samples; for its own brand, it invests in content, reviews and discovery ads. It measures margin per structure and decides to raise the own-brand budget, where final margin is higher.
Frequently asked questions
Should I advertise both?
Many shops do. What matters is separating strategies and targets.
What margin should I expect?
Usually higher on the own brand. Calculate by product.
How do I avoid cutting the own brand?
By setting a protected budget and its own long-term metrics.
How do I separate them in reports?
Using custom labels in the feed or product groups by brand.
Should I advertise third-party brand names?
You can, respecting platform and legal trademark rules; confirm them.
Structure and measure own and third-party brands separately: the former builds demand and margin, the latter competes on service and selection.
