What is Non-Endemic Advertising & Why Does it Matter for Retailers?

February 12, 2025

Non-endemic advertising is unlocking new revenue streams, and positioning retailers for smarter, more strategic growth.

With more than half (53%) of brands already leveraging non-endemic advertising through commerce media networks, now is the time for retailers to capitalize on this growing opportunity.

But what exactly is non-endemic advertising?

Here’s everything you need to know to incorporate this growth driver into your commerce media ecosystem.

What is Non-Endemic Advertising?

Endemic ads feature products either sold by a retailer or native to the website on which they are displayed. For example, an ad for running shoes on a sportswear retailer’s website

Endemic Advertising Example

Non-endemic advertising promotes products or services that are outside of the retailer’s core industry or product category, but still relevant to the shopping experience. For example, an ad for a healthy meal delivery subscription service on a sports retailer’s website.

Non-Endemic Advertising Example

Why it matters: Non-endemic ads enable retailers to attract diverse advertisers while still offering value to shoppers. Advertisers expand their reach, build brand awareness, and attract new customer segments outside of traditional, industry-specific channels. The flexibility and new revenue streams have attracted large retailers, including Amazon, Walmart, and Home Depot.

The Value of Non-Endemic Advertising in Commerce Media 

EMARKETER reports that non-endemic brand partnerships are crucial for long-term growth. Non-endemic advertising delivers the following benefits :

Benefits for Retailers

Increased Revenue

By selling ad space to non-endemic brands, retailers unlock a new revenue stream without relying solely on product margins or traditional ad models. Learn how Fluent helped a DTC retailer drive a 40% increase in revenue per session with non-endemic, post-purchase ads.

Improved Customer Experience

Powered by privacy-safe first-party data, non-endemic ads improve the customer journey by addressing shoppers’ needs and interests. 

The impact? Stronger brand loyalty. In fact, according to a Fluent survey, 88% of those who say non-endemic, post-purchase ads improve the shopping experience through personalized offers are more likely to return.

Benefits for Advertisers

Access to New Audiences

Non-endemic advertising delivers access to broader audience segments. Take our example from the beginning of this post. When a meal delivery service promotes a subscription box on a sports retailer’s website, it improves visibility, reaching shoppers across various demographics and interests.

Boosted Brand Awareness

Studies show that brands need at least 6 to 7 impressions to produce brand awareness. The more relevant and trusted partnerships advertisers build, the greater their opportunity to scale impressions through non-endemic ads.

How Retailers Can Effectively Leverage Non-Endemic Advertising

Prioritize Relevance

Disruptive ads can drive customers away—40% of consumers find irrelevant ads overwhelming, and 51% will unsubscribe or block brands that miss the mark.

The solution? Personalization and relevance. Non-endemic advertising offers new creative opportunities, but success depends on delivering offers that genuinely align with shoppers’ needs and interests.

Collaborate with Trusted Brands

As non-endemic advertising grows, the competition for quality ad inventory intensifies. Retailers should prioritize partners who can deliver high-quality ad experiences that align with shoppers’ interests and support brand trust. These partnerships offer more longevity, which delivers greater revenue growth.

Tap Into the Post-Purchase Moment

The post-purchase moment is an (often) untapped opportunity to surprise and delight consumers with non-endemic offers that complement their recent purchases. Turn the confirmation page into a revenue-driving opportunity, introducing customers to relevant products and services – all without interrupting the sale.

When leveraging post-purchase ads, use first-party data to match non-endemic ads with the right audiences.

Test, Learn, and Optimize: A/B Testing and Performance Metrics

Continuously test ad placement, creatives, and messaging to maximize ROI. We recommend tracking:

  • Click-Through Rate (CTR): CTR measures ad engagement. Fluent drives an average CTR of 8.04% for post-purchase ads, compared to the 0.51% industry average for ecommerce display ads.
  • Conversion Rate: Conversion rate calculates the percentage of shoppers who complete a desired action. Ad quality, along with the relevance of the offer and the effectiveness of the call to action, impacts conversion rate.
  • Revenue Per Session (RPS): RPS measures the average amount of revenue generated per user session on a website or app. Calculate RPS by dividing your total revenue in a specific timeframe by the total number of user sessions during the same period.

By partnering with non-endemic advertisers, retailers are reaching new revenue streams, delivering richer customer experiences, and significantly boosting customer lifetime value.
