Evaluating a Mid-Tier Ad Network Vendor at the Show

Devcom opens in Cologne this week, and the vendor floor there does something a scheduled sales call rarely does: it puts a dozen mid-tier ad networks within a few minutes' walk of each other, all making similar claims about scale, fraud controls and incremental reach beyond the three or four networks that already carry most of a studio's budget. Evaluating a mid-tier ad network vendor under those conditions rewards a different discipline than evaluating one from a deck sent over email, because the comparison is live and the sales pitch is optimised for the room, not for a buyer's actual campaign data.

Why booth pitches understate the diligence needed

A booth conversation compresses a vendor's pitch into the two or three points that sound best out loud: scale claims, a marquee client name, and a fraud detection story. None of those three, taken at face value, tells a buyer whether the network's inventory overlaps meaningfully with what a studio's existing networks already reach, or whether it would add genuinely incremental volume. A vendor with real geographic or format strength worth testing and a vendor with an inflated version of the same pitch sound identical in a five-minute booth conversation. The difference only shows up once someone asks for specifics a slide deck does not volunteer.

Evaluating a mid-tier ad network vendor's claims on the floor

• Ask for genre-specific benchmarks, not blended ones. A network's average CPI or ROAS figure blends every vertical it serves. A studio running a hybrid-casual title needs that network's hybrid-casual numbers specifically, and a vendor unwilling or unable to produce them at the booth is a signal worth noting.
• Ask which MMPs they integrate with natively versus through a third-party bridge. A native SDK integration with a studio's existing MMP is a meaningfully lower-risk starting point than one requiring a workaround, particularly for a first test.
• Ask what percentage of their inventory is exclusive versus resold from other exchanges. A network reselling inventory a studio already buys elsewhere adds reporting overhead without adding reach, however good its dashboard looks.
• Ask how they handle SKAdNetwork and AdAttributionKit reporting specifically for games, rather than a general answer about privacy compliance, since games campaigns depend on postback timing and conversion value mapping in ways that differ from e-commerce or utility app advertisers.

A capped-test framework for the follow-up

The value of a show conversation is not a signed insertion order by the end of the week. It is a shortlist worth a small, time-boxed test once the team is back at their desks with campaign data in front of them.

• Set a fixed test budget before the conversation ends, ideally a figure small enough that a poor result costs little but large enough to reach statistical confidence within the campaign's normal attribution window.
• Request a written scope note within a week of the show, covering the specific claims made at the booth: genre benchmarks, integration path, inventory exclusivity. A vendor who cannot put the booth pitch in writing quickly is telling a buyer something about how the relationship will run under normal account management.
• Run the test against the same creative already live elsewhere, not a bespoke asset built for the new network, so any performance difference reflects the network's audience and bidding rather than a confound in the creative itself.
• Set the decision date in advance, and hold to it regardless of how the vendor's account team responds mid-test. A network with a genuinely strong result does not need an extension to prove it.

Reading the room, not just the pitch

A booth's staffing tells a buyer something a slide never will. A network sending its own performance or data science team to the floor, rather than exclusively sales staff, is generally more willing and able to answer the specific benchmark and integration questions above on the spot. A vendor who can only offer to "follow up with the team back at the office" on basic questions about their own integration path is signalling how account management is likely to run once a contract is signed, and that signal is worth weighting alongside the substance of the pitch itself.

It is also worth watching how a vendor's booth pitch changes across the course of a multi-day show. A network that tightens its claims and gets more specific in response to pointed questions from earlier conversations is behaving like a team that takes buyer feedback seriously. One that repeats the identical pitch regardless of what a buyer pushes back on is worth discounting slightly, since that same rigidity tends to show up later in how flexible the account team is once a real test throws up an inconvenient result.

What separates a real find from a booth story

The mid-tier networks worth adding to a media plan after a show are the ones whose claims survive contact with a studio's own attribution data, not the ones with the busiest booth. A studio that runs three or four capped tests from a single show floor, holds each to the same evaluation criteria, and is willing to walk away from the two that do not clear the bar will end up with a genuinely stronger network roster than one that adds every vendor who made a confident pitch. The floor is useful for generating the shortlist. The account's own data still has to make the decision.

Devcom and the wider Gamescom week produce a fresh crop of these shortlists every August, and the temptation to sign several vendors at once, riding the momentum of a good show, is exactly the moment discipline pays off most. Three well-run capped tests, each properly isolated and measured against the same evaluation criteria, will tell a buyer more than five relationships started on enthusiasm and left to prove themselves without a fixed decision date.
