Marketplaces like Amazon, Cdiscount and Fnac have become a must for e-tailers wishing to reach a wide audience. Yet competition is fierce, and without an effective e-commerce advertising strategy, it’s hard to stand out from the crowd. Advertising on the marketplace helps improve product visibility, attract more customers and increase sales. But you still need to know how to optimize your sponsored campaigns for maximum advertising ROI.
In this article, we explain why you should invest in advertising on marketplaces, how to structure an effective strategy, and which are the most effective advertising formats for boosting your sales.
Why invest in advertising on marketplaces?

Marketplaces have become major players in e-commerce, capturing a large proportion of online traffic and purchases. Investing in sponsored campaigns on these platforms has become a necessity to remain competitive.
The benefits of sponsored campaigns
Sponsored campaigns reach a highly qualified audience. Unlike other acquisition channels, they target buyers who are actively searching, which increases conversion rates. What’s more, they offer considerable budgetary flexibility: advertisers can adjust their investments according to performance and ROI.
Finally, they enable a rapid launch and immediate ramp-up, whereas SEO strategies require several months of effort before they are effective.
Comparison with other advertising channels
Marketplaces offer advertising opportunities that are distinct from traditional channels such as Google Shopping or social networks. On Google Shopping, ads reach a wider audience, but one that is not necessarily ready to buy. Conversely, marketplace advertising targets exclusively consumers with a clear intention to buy.
Facebook Ads campaigns, on the other hand, can be used to build brand awareness, but are often less effective in generating immediate sales. The ideal solution for an e-tailer is to adopt an omnichannel advertising strategy, combining several sources of traffic while optimizing marketplace campaigns to maximize profitability.
How do you build an effective advertising strategy?

Launching an advertising campaign on a marketplace is more than just investing a budget and hoping for results. To maximize ROI, it’s essential to adopt a methodical approach. A well-thought-out strategy rests on three pillars: the definition of objectives and budget, the choice of formats and targeting, and the ongoing optimization of campaigns.
Define your objectives and budget
Before launching a campaign, it’s crucial to precisely identify the objectives to be achieved. Each company may have different priorities, depending on its market positioning and the maturity of its activity on marketplaces. Some seek to increase brand awareness by maximizing the visibility of their products, while others focus on acquiring new customers or optimizing advertising profitability.
Defining an appropriate budget is a key step in ensuring campaign effectiveness. It must take into account several factors, including the average cost per click on the targeted platform, competition in the sector and margins on promoted products. A budget that’s too low can limit the impact of ads, whilea budget that’s not properly controlled can lead to unnecessary expenditure.
A good practice is to test different budget allocations over a defined period, regularly analyzing performance to adjust investments. The aim is to find the right balance between advertising expenditure and return on investment, in order to optimize campaign profitability.
Choosing the right targeting and formats
The choice of targeting and advertising formats is a key step in ensuring campaign effectiveness. There are several approaches to targeting:
- Keyword targeting: this allows ads to be displayed according to users’ searches on the marketplace. A good choice of keywords, including both generic and specific terms, improves ad relevance.
- Automatic vs. manual targeting: automatic campaigns use the marketplace’s algorithm to deliver ads optimally, while manual campaigns allow more precise control over bids and keywords.
- Audience targeting: this involves reaching specific customer segments, such as visitors who have viewed a product but not purchased it, or buyers of a complementary product.
The choice of advertising formats also depends on your objectives:
- Sponsored Products: ads visible directly in search results or on competing product pages.
- Sponsored Brands: advertisements featuring several products from the same brand, often at the top of search results.
- Sponsored Display: retargeting buyers who have already shown an interest in a product.
By combining several formats and adapting targeting, it is possible to improve product visibility and attract a more qualified audience.
Optimize your campaigns for better ROI
Once a campaign has been launched, its effectiveness depends on rigorous monitoring and regular optimization. Performance analysis enables us to adjust strategies according to the results obtained, identifying the most profitable ads and those requiring adjustment. Several key indicators need to be closely monitored. The click-through rate measures the attractiveness of the ad, and indicates whether the visuals and descriptions are sufficiently engaging.
A low click-through rate may be a sign of poor targeting or ineffective layout. The conversion rate, on the other hand, reflects an ad’s ability to generate sales. If this rate is low despite a good volume of traffic, this may indicate a problem with the product sheet or the item price. ACoS (Advertising Cost of Sale) is a particularly important indicator. It expresses the ratio between advertising expenditure and sales generated. An ACoS that is too high means that the campaign is unprofitable and requires a revision of bids or targeting.
To improve performance, it’s essential to adjust bids according to the results obtained, increasing investment in the best-performing ads and reducing investment in less profitable campaigns. Testing different ad variations, with distinct visuals or messages, also helps identify the most effective formats. Finally, a well-optimized product sheet, with clear descriptions, attractive visuals and positive customer reviews, plays a decisive role in the success of a campaign.
The main advertising formats on marketplaces

Each marketplace offers its own advertising formats, designed to meet the specific needs of sellers and optimize product visibility. To maximize the performance of your campaigns, it’s essential to understand the differences between these formats and adopt the right strategies for each platform.
Amazon Ads: how does it work?
Amazon Ads offers several solutions for promoting products and improving their visibility on the platform. Sponsored Products are the most commonly used: they display products at the top of search results or on product pages. This format works on a cost-per-click (CPC) bidding model, where advertisers define a budget and keywords to target their campaigns. Sponsored Brands, on the other hand, showcase a brand with a banner ad containing several products and a logo.
Finally, Sponsored Display allows you to retarget users who have already visited a product page, by displaying ads on Amazon or partner sites. One of the main advantages of Amazon Ads is the ability to adjust bids according to the return on advertising investment, thanks to ACoS (Advertising Cost of Sale).
Advertising on Cdiscount and Fnac: what are the differences?
Cdiscount and Fnac also offer advertising formats for sellers wishing to improve their positioning on these marketplaces. Cdiscount Ads works on a similar model to Amazon, based on an auction system that allows products to be sponsored directly in search results or on product pages. This format is particularly effective for high-demand sectors, such as electronics and household appliances.
Fnac Marketplace Ads, meanwhile, offers interesting opportunities, with competition generally weaker than Amazon, enabling sellers to achieve good visibility with a more moderate budget. The main challenge on these platforms is to adapt the advertising strategy to an audience that is often different from Amazon’s, with particular attention paid to prices and customer reviews.
Retail media: a new advertising opportunity
Retail media represents a growing opportunity for e-tailers wishing to go beyond simple sponsored campaigns on marketplaces. This advertising format consists of displaying ads directly on partner e-commerce sites, targeting consumers in the act of buying. The ads can appear as banners on product pages, in the order tunnel or even as personalized recommendations.
This approach enables brands to capture the attention of potential buyers even before they carry out an active search. What’s more, the data collected through retail media offers valuable insights into consumer behavior, enabling advertising campaigns to be fine-tuned and ROI optimized.
