How should retailers plan programmatic advertising around peak season?
Part of Programmatic media planning
The short answer
Retailers plan programmatic around peak season by fixing the calendar first, then building a publisher list in groups: editorial sites that match the products, review and gift guide publishers, and deal and coupon sites checked separately. Store and marketplace sites stay out of the open web list, since their ad space is bought as retail media.
Key takeaways
- The US and Canadian peaks fall on different dates: Canadian Thanksgiving on October 12, 2026, US Thanksgiving on November 26 and Boxing Day on December 26.
- Peak demand is uneven by category; the US Census Bureau estimates 13.7 percent of 2024 hobby, toy and game store sales happened in December.
- A retail site list works best in groups with their own budgets: product editorial, review and gift guides, local news, and deal and coupon publishers.
- Store, brand and marketplace sites are left off an open web publisher list, because their ad space is sold as onsite retail media on the retailer's own properties.
- Deal and coupon sites earn their place only after checks for affiliate disclosure, authorized sellers and page quality.
How should retailers plan programmatic around peak seasons?
A retail plan starts from the dates that move sales, not from the media calendar. The demand curve differs by category. The US Census Bureau (opens in a new tab) estimates that 13.7 percent of 2024 hobby, toy and game store sales occurred in December, and that electronic shopping and mail-order houses had their highest estimated monthly sales of 2024 in December, at $146.6 billion. A toy retailer and a furniture retailer may share a holiday, but not the same weeks of pressure.
Month boundaries also move. Statistics Canada (opens in a new tab) reported unadjusted retail sales of $71.0 billion in November 2024 and $72.0 billion in December 2024, and said "Cyber Monday's timing in December 2024 possibly contributed to the larger uptick" in December. A plan that compares this year's November with last year's should check where the shopping weekend fell each year.
Lead time matters as much as the dates. Site lists, curated deals and creative approvals take time to set up and test. Building and approving the list a month before the first peak date leaves room to fix a deal that will not deliver.
How do US and Canadian retail calendars differ?
The two countries share Christmas and little else in the fall calendar. Canadian Thanksgiving falls six weeks before the American one, and Boxing Day is on the Canada Revenue Agency's public holiday list but not on the US federal holiday list. The table uses the official 2026 calendars from the Canada Revenue Agency (opens in a new tab) and the US Office of Personnel Management (opens in a new tab).
| Date | Event | Country | Planning note |
|---|---|---|---|
| Monday, October 12 | Thanksgiving Day | Canada | Already past for 2026; Canadian fall plans now run toward November and December |
| Thursday, November 26 | Thanksgiving Day | US | Federal holiday; the shopping weekend follows it |
| Friday, November 27 | Black Friday | US and Canada | The Friday after US Thanksgiving; a retail event, not a holiday in either country |
| Monday, November 30 | Cyber Monday | US and Canada | The Monday after; it can fall in December, which moves sales between months |
| Friday, December 25 | Christmas Day | US and Canada | Plan around the retailer's own shipping cutoff dates |
| Saturday, December 26 | Boxing Day | Canada | On the CRA public holiday list; not a US federal holiday |
Cross border plans need two calendars in one file. A retailer selling in both countries can run one creative idea but should date each country's flight to its own peak, set prices in the right currency,.
Which publishers suit retail campaigns?
A retail list mixes publisher types that behave differently, so it is planned in groups. Each group answers a different question in the buyer's path, has its own risks and deserves its own budget line, so that one group cannot quietly absorb the money meant for another.
| Group | What it contributes | What to check | Where it fits in the flight |
|---|---|---|---|
| Product and hobby editorial | Readers already interested in the category | Recent articles on the category, ads.txt, page quality | Throughout, starting before the peak |
| Review and gift guide publishers | Readers comparing products before buying | Affiliate disclosure, original testing, update dates | Weeks before the peak |
| Local news and community sites | Reach near physical stores and local events | Audience in the store's market, selling path | Store events and final shopping days |
| Parenting and family sites | Gift buyers for children's categories | Suitability for the brand, page quality | Gift season |
| Deal and coupon publishers | Readers ready to buy on price | Disclosure, authorized sellers, ad density | Sale days only, in a separate line item |
Grouping makes delivery readable. When each group sits in its own line item or deal, a report by group shows whether review sites delivered before the peak and whether deal sites took a share far beyond their role. Display & Video 360, for example, lets a line item include or exclude "any combination of apps, channels, collections, or URLs," up to "a combined total of 10,000 individual apps and URLs," per its targeting help (opens in a new tab).
Why are store and marketplace sites left out of site lists?
Retailers do sell ad space on their own sites, but it is a different product. The IAB's Retail Media Buyer's Guide (opens in a new tab) of July 2023 describes onsite retail media as ads "within a retailer's e-commerce platform, such as search result pages, product pages, and category pages," and says onsite opportunities "are restricted by available ad space and shopper page visits." That inventory is bought through the retailer's media network on its terms, not as open web publisher supply.
For an open web site list, a store or marketplace domain causes three problems. Its pages are product listings rather than editorial content, so a contextual match says little about the reader. It may sell competitors' products beside the ad. And when the retailer running the campaign is itself a store, a list full of other stores sends its budget to rivals. Brand sites, which promote one company's products, raise the same issues.
Signs a candidate is a store or marketplace, not a publisher
- Sampled pages are mainly product listings with prices and add to cart buttons.
- The site's own structured data describes products or offers rather than articles.
- Third party sellers list their goods on the site under their own names.
- Editorial pages exist but sit under a shop section and link mainly to product pages.
- The site's ad space is sold through a retail media program rather than listed for programmatic buyers.
How do retail plans handle deal and coupon sites?
Deal and coupon sites reach shoppers at the moment of purchase, and their business model is commission on sales. That makes disclosure the first check. The FTC's endorsement guide FAQ (opens in a new tab) tells affiliate marketers to "disclose your relationship to the retailer clearly and conspicuously on your site," and warns that consumers "might not understand that 'affiliate link' means that the person placing the link is getting paid." In Canada, Ad Standards' Interpretation Guideline #5 (opens in a new tab), updated October 2020, says "affiliate marketing and refer-a-friend programs may also trigger disclosure requirements."
Five checks before a deal or coupon site joins a retail list
- Read the disclosure. Confirm the site states its affiliate relationships clearly and close to the recommendations, in line with the FTC and Ad Standards wording.
- Check who sells it. Open the site's ads.txt and confirm DIRECT or RESELLER entries for the exchanges in the plan, as the ads.txt specification (opens in a new tab) defines them.
- Look at the page. Load several deal pages on a phone and on a desktop and note how much of the screen ads take and whether slots refresh.
- Confirm it is a publisher. Make sure the site publishes its own deal content rather than acting as a storefront.
- Isolate it in the plan. Put deal sites in their own line item, dated to sale days, so their delivery can be read apart from editorial sites.
Deal sites are not a quality problem by definition. A well run coupon publisher with clear disclosure and reasonable ad layout serves a real reader. The checks keep the good ones apart from sites built mainly to collect ad revenue, and the made for advertising guide explains the signs that separate the two.

Fictional example
A toy and board game store chain in Alaska and the Yukon
An unnamed toy and board game store chain with stores in Anchorage, Fairbanks and Whitehorse plans display from mid November through December 26, 2026. The brief targets parents, grandparents and board game hobbyists in Alaska and the Yukon, in English, with US and Canadian dollar budgets kept apart.
The planner builds four groups: board game and hobby review sites, parenting and family activity sites, local news in the three cities, and two coupon publishers that clear the disclosure and ads.txt checks. Online toy stores and marketplaces that surface as candidates are left out, since their ad space is sold as retail media.
The US flight weights the week of November 27 and the final shipping days; the Canadian flight carries extra budget into December 26 for Boxing Day. Coupon sites run only on sale days, in their own line item, and the report reads delivery by group.
Frequently asked questions
Should a retailer run programmatic on its own website?
That is retail media, not open web programmatic. A retailer's own site carries its onsite ad program, sold to brands that want shoppers in a buying state of mind. For the retailer's own campaigns, the open web list should point to publishers its customers read.
How long should a retail site list stay live after the peak?
Retire or pause peak only groups, such as deal and coupon publishers, when the sale period ends, and keep evergreen editorial groups running at a lower budget. Record the date each group was paused so the next season starts from a known list.
Do retail plans need different lists for the US and Canada?
They need the same checks but can need different sites, because a publisher popular in one country may have little audience in the other. Build each country's list from audience in that market, then share only the sites that fit both.
Can review sites with affiliate links be trusted for brand placements?
Affiliate income alone does not disqualify a review site. Check that the relationship is disclosed clearly, that reviews show signs of real testing and recent updates, and that the page layout leaves room for the content. Then place the site in its own group.
