Chewy is quietly turning its website into a powerful advertising marketplace, using customer habits and subscription data to help pet brands find buyers. The company’s ad tools have grown quickly, and brands are responding as Chewy tightens the link between marketing dollars and long-term customer value.

Rapid expansion of Chewy’s ad platform and what it means

Since launching its ads offering in 2023, Chewy has seen fast adoption among brands. In a year, the platform more than doubled both the number of advertisers and the campaigns they run.

• High conversion rates: About one in three ad clicks on Chewy leads to a purchase, the company reports.
• Many shoppers are exposed to brands they hadn’t seen before after interacting with ads.
• Sponsored listings, video placements and co-branded displays are all part of the mix.

Executives say ad sales helped lift margins in the most recent fiscal year. While Chewy has not published exact ad revenue totals, it told investors that sponsored advertising was a central factor in margin improvement during fiscal 2025.

Building the engine: moving from third-party to an in-house platform

Chewy’s ad business began on an outside platform. Migrating to an in-house stack gave the company more control and deeper targeting options.

Why the switch matters

• Brands can access more detailed audience signals.
• Chewy can roll out advanced features without external limits.
• The in-house setup supports integrations across Meta, TikTok and Google.

The internal team that built the system includes ad veterans who previously worked on other retail ad networks. That experience helped Chewy accelerate product development and engineering efforts.

Chewy Max: AI targeting tuned to pet shoppers

In March, Chewy released Chewy Max, a set of tools that layers AI on top of the company’s customer data. The suite aims to help brands reach shoppers with higher lifetime value potential.

• Targeting can be optimized for lifetime value (LTV) rather than just immediate return.
• Chewy leverages 15 years of purchase history to power predictions.
• Auto-ship behavior plays a major role in audience modeling.

With more than 20 million active customers and a large share of sales coming through autoship, Chewy can identify buyers with strong purchase intent. That data backbone is the “secret sauce” executives cite when describing their ad advantage.

How performance and measurement are sold to brands

Chewy emphasizes transparency for advertisers. Dashboards show campaign performance along with forward-looking metrics that matter to brands.

• Lifetime value return on ad spend (LTV ROAS) appears alongside traditional ROAS figures.
• Advertisers can see how many customers enroll in autoship after an ad exposure.
• Incremental ROAS (iROAS) is available to show net-new revenue driven by ads.

On average, Chewy reports that advertisers generate multiple dollars in lifetime sales for each ad dollar spent. That focus on future value makes the platform attractive to brands willing to invest in customer acquisition.

Retail media at large: the market opportunity and where Chewy fits

Retail media is expanding quickly industry-wide. Recent research projects tens of billions in growth over the coming years, highlighting why niche marketplaces matter.

• A major analyst forecast predicts retail media spend will rise from roughly $184 billion in 2025 to about $312 billion by 2030.
• Amazon and Walmart capture the bulk of spend, but category leaders can still carve out meaningful share.
• Specialized platforms like Chewy can win for brands focused on pet owners.

Industry observers note that category-specific sites often deliver better alignment between advertiser goals and shopper intent. For pet brands, the argument is simple: reach pet parents where they already shop.

Ad formats, offsite reach and streaming pilots

Chewy’s ad inventory spans onsite placements and offsite media. Brands can extend campaigns beyond Chewy’s site using major social and search channels.

• Onsite: sponsored products, brand stores, video units and content sponsorships.
• Offsite: ads that run on Meta, TikTok and Google to drive traffic back to product pages.
• Connected TV trials are underway to test longer-form storytelling and brand awareness.

Why lifetime value becomes a bargaining chip

Brands often focus on short-term ROAS. Chewy’s pitch centers on the value of the customer over months and years, not just the first sale.

When advertisers can see projected lifetime returns, they tend to increase acquisition budgets. That dynamic helps explain why Chewy prioritizes LTV measurement and autoship conversion as core metrics.

Internal dynamics: merchandising vs. ad teams

Introducing more advertising to a retail site can create internal friction. Merchandisers and ad teams sometimes disagree about what serves customers best.

At Chewy, leadership says the guiding principle is simple: make it easier for pet parents to find the products they need. That customer-first stance is used to align internal teams around ad placements and vendor promotions.

Expert views on specialized retail media

Analysts point out that retailers built around a single category can become powerful ad platforms. Success depends on data depth and buyer intent.

• Category specialists can offer advertisers clearer signals on purchase propensity.
• Visibility into repeat purchases and subscription behavior sets them apart.
• For many brands, paying more for a higher-quality customer is an acceptable trade.

For Chewy, the combination of first-party data and autoship patterns is the competitive advantage it sells to advertisers.
