Open auction
Broad access to eligible inventory through real-time bidding.
Ask: what inventory and exclusions are applied?Programmatic advertising in Canada
Understand the
media-buying machine.
Programmatic is automated digital media buying across display, video, audio, CTV and other inventory. The useful question is not whether the buying is automated, but what inventory, data, controls, fees and measurement sit behind the campaign.
Canadian contextIAB Canada
89%+of Canadian digital display ad spend was estimated to be programmatic in 2025 by IAB Canada.
That makes programmatic infrastructure a core part of modern display buying rather than a niche tactic.Buying ecosystem

Buying methods
Open auction is only
one way to buy.
The commercial and quality controls can change depending on how inventory is accessed.
Private marketplace
Selected buyers access selected publisher inventory under defined deal terms.
Ask: which publishers and what priority?Preferred / guaranteed
Directly negotiated inventory can add predictability, premium context or volume commitments.
Ask: what is guaranteed?Data-driven activation
Audience, contextual or first-party signals shape where bids are placed.
Ask: where did the data come from?Cost transparency
Media spend is not
the same as working media.
Before comparing CPMs, ask which technology, data, verification and service fees sit between the advertiser and publisher.
Platform fees
DSP, data, verification, serving and agency fees can all affect the share of budget reaching inventory.
Brand safety
Define blocked categories, inclusion lists, verification tools and suitability rules before launch.
Supply path
Know whether the campaign has a clear route to publishers or unnecessary intermediary complexity.
Measurement
Viewability, reach, conversions, incrementality and business outcomes answer different questions.
