Access to the platforms below is table stakes. The job is choosing.
More platforms is not more reach. Run the same campaign in two DSPs and you bid against yourself for the same impressions, you lose control of frequency across them, a brand study’s exposed group gets contaminated by the other platform’s delivery, and the measurement has to be set up twice and reconciled once. Sometimes a second platform is still right. When it isn’t, we say so, including when the plan already has it and saying so costs us the business.
So here is what we use each one for, what we don’t, and what we watch for. It changes as the platforms do. The iOS 26 note on The Trade Desk is a recent example.
Programmatic
The Trade Desk
What we use it for. Connected TV first. It has the deepest CTV supply through direct publisher relationships, it is the largest independent DSP, and it lets us bring our own measurement partners. For a CTV campaign with a conversion goal, or an omnichannel campaign where a brand study is the north star and you don't have first-party audience data, it is usually where we start. Asset managers are the typical case.
What we watch for. Identity. With a server-to-server UID2 integration, built on emails your customers consented to give you, targeting and attribution on CTV hold up. With pixels and browser-captured IDs, they don't, and since iOS 26 they hold up less. For display and online video with a cost-per-acquisition goal, we often look elsewhere.
A detail that matters in finance. On the finance networks, guaranteed deals open far more inventory than private marketplaces, at a higher price. We buy both, and we say which one carried the result.
Display & Video 360
What we use it for. Display and online video with a conversion goal, where signed-in Google data makes targeting and attribution work after the cookie workarounds stopped. YouTube, which is only bought here. And the brand lift study comes with the buy, which matters when a budget can't carry a paid study.
What we watch for. The numbers are Google's. A conversion counted in DV360 is checked against your analytics before it reaches your reporting, and the same ad server counts across every platform so no two of them claim the same sale.
Amazon DSP
What we use it for. Consumer brands, where Amazon's shopper signals are the best signed-in data outside Google, and streaming TV inventory that other DSPs don't reach. For display with a conversion goal, it is the second option we consider after DV360.
What we watch for. It reports on its own terms, and it is built to keep you in its own inventory. We take the reach and read the result in your analytics.
Search
Search Ads 360
What we use it for. Paid search optimized to your objective rather than to the click: a lead that becomes a customer, a quote that becomes a policy, an order. Bid strategies run against the conversion you define, and each business line gets its own. A lead-generation account run this way cut its cost per lead by more than a third while leads nearly doubled.
What we watch for. Search finds the demand that already exists. When it is the only channel, the cheapest leads are often the wrong ones, so site engagement by channel and the lead-to-customer rate from your records stand beside the cost per lead.
Social
Meta
What we use it for. Consumer reach and retargeting with a conversion goal, in your account so the history stays yours. It is in most of our consumer plans and in few of our finance plans.
What we watch for. Attribution that counts generously, and conversion events that fire on the wrong page. Before we spend, the Conversions API is checked against your records, and a "purchase" has to mean a purchase. In health, we check what the pixel sends before it sends anything.
What we use it for. Business audiences where the objective is to be thought of first: a media company selling to agencies and brands, an asset manager reaching advisors, a firm whose buyers have a job title. The brand study is the point. We ask the same question every quarter and pool the results, so each study adds to the last.
What we watch for. The CPMs are the highest in digital, so it is a brand channel with a study attached, not a lead channel. Reach wide at a modest frequency rather than hammering a small list; the lift came at a frequency of about three, not ten.
What we use it for. Context when identity is gone. Reddit targets the conversation rather than the person, which is where display is heading, and it reaches audiences that research before they buy: investors, patients, people comparing products. It is newer in our plans than the platforms above, and it is in our reporting as its own channel.
What we watch for. Tone. A finance or health ad that reads as an ad gets the response Reddit gives ads. Creative built for the place, or none.
Out of home
Vistar Media, and direct
What we use it for. Moments where the audience is in one place: an advisor conference, a trade show, a city during a launch. Vistar reaches the screens programmatically. For the screens that matter most, the airport concourses, the streets around the venue, the kiosks inside, we go direct to Clear Channel, Outfront and the venue, because the programmatic marketplace doesn't carry them. Sometimes that means calling every vendor in a city. One conference, end to end.
What we watch for. Impressions in out-of-home are estimates of people passing a screen. We report them as that, and we look for the result where it would show: site traffic from the city during the dates, a brand study where the budget supports one.
Direct, and the ad server
Publisher deals
What we use it for. The placements no auction sells: a homepage takeover on a Federal Reserve day, a custom video unit, a publisher's own advisor audience, a direct deal on a finance network's streaming inventory. In finance these are a large share of the plan, and most of them underperform the same inventory bought by CPM. We audit every one against its alternative and keep the ones that earn it, at a price we negotiate ourselves.
Who we buy from directly. NBCUniversal, Netflix, Bloomberg, CNBC, Fox, Dow Jones, Yahoo, Investopedia, Reuters, Spotify, Clear Channel and Outfront, to name some. Relationships that go back years, with the people who sell the inventory, not a form.
Both desks. Every large publisher has a direct sales team and a programmatic team, and they do not always talk to each other. We work with both: the programmatic team to open a guaranteed or private deal we can run in our seat, the direct team when a placement or a price only exists on their side. Which desk a placement came through is in your reporting.
What we watch for. Fixed prices and the publisher's own numbers. Every direct placement is ad-served and verified so it is counted the way everything else is, and a sponsorship that can't be measured doesn't get renewed.
Campaign Manager 360
What we use it for. One count. Every platform reports its own conversions and claims the same sale. The ad server sits across all of them, so there is one record of what ran, where, and what followed, and your reporting is built from it rather than from eight platforms' opinions of themselves.
How we choose
The platform follows the objective, and the objective is written down first.
The Trade Desk
Display & Video 360
Search Ads 360
LinkedIn
Reddit
Vistar Media
Campaign Manager 360A brand study. Every DSP and social platform here can run one. Connected TV on The Trade Desk with a third-party study, which is the one we trust most. LinkedIn when the audience has a job title. Meta, DV360 and Amazon include their own studies, which is useful when a budget can't carry a paid one, as long as the platform grading its own work is read as that.
Conversions on connected TV. All three DSPs report connected TV conversions. We start on The Trade Desk, with server-side UID2 so the household that saw the ad can be matched to the visit that followed, and move to DV360 or Amazon when their signed-in data is where your buyers are.
Conversions on display and video. DV360 first, then Amazon DSP, where the signed-in data lives. The Trade Desk when the plan already runs there, so one platform keeps all the signal. Meta for consumer brands, Reddit for buyers who research first. Contextual strategies overweighted everywhere.
Leads from existing demand. Search Ads 360 first, managed to the conversion you define, with lead quality checked against your records. LinkedIn and Meta lead forms when the audience is defined by who they are rather than by what they searched.
A moment in one place. Vistar for the screens programmatic reaches, The Trade Desk when the plan already runs there, and direct deals for the concourses, the streets around the venue and the kiosks inside.
A placement no auction sells. A direct deal with the publisher, audited against its CPM alternative, counted by our ad server and verified like everything else.
Tap an objective. Every platform that fits lights up; the note says where we usually start.
Those are the usual starting points. The exceptions are the job. A finance brand with no first-party data and a brand study to run belongs on The Trade Desk even for display. A consumer brand whose buyers are on Amazon may do its best conversion work there, not on Google. A client with a strong relationship at one publisher can get a price in a direct deal that no auction would give. We make the call for the circumstances in front of us, we write down why, and we change it when the evidence says to.
What we won’t do is run a platform because it pays us to. We have no media of our own to sell, and we’d rather run one platform your measurement can read than four it can’t.
