The landscape of game marketing has evolved dramatically over the past decade. In the early days, developers and publishers would simply buy ad space, hoping that the sheer volume of impressions would translate into awareness and, eventually, sales. That approach made sense when most titles were sold as boxed, single‑player experiences. Today, however, the dominant model on PC is free‑to‑play live‑service games, and the old tactics no longer deliver the needed results.

Amit Nagrani, who heads business development and client success at PWN Games—a performance‑marketing specialist celebrating its tenth anniversary—observes that many PC publishers still cling to traditional awareness‑focused campaigns. These include brand pushes, influencer collaborations, and paid media on platforms such as Meta, Google, YouTube, and Twitch.

While such tactics can still work for premium, one‑off purchases, they are ill‑suited for live‑service titles that rely on a steady stream of new players and ongoing monetisation. "For premium games, the purchase is the end goal," Nagrani explains. "The marketing spend is heavily weighted toward building awareness and consideration before launch—creating wishlists, generating buzz, and then amplifying everything with a launch‑day push.

Once a player buys and installs, the revenue is essentially guaranteed." By contrast, live‑service free‑to‑play games operate on a completely different premise. "You can’t ride a single launch wave and call it a day," he says. "You need a continuous influx of players over months and years, and the real revenue comes from keeping those players engaged and eventually converting them into paying customers." Traditional user‑acquisition (UA) models—cost‑per‑mille (CPM) and cost‑per‑click (CPC)—pose financial risks for live‑service titles. Historically, publishers expected to recoup acquisition costs within a month, a timeline that made sense when many PC publishers were transitioning from the mobile free‑to‑play world.

Today, depending on genre and region, the payback period can stretch from three to twelve months. The longer horizon demands greater confidence that the acquired users will generate sufficient lifetime value (LTV).

CPM charges advertisers for every thousand ad impressions, regardless of whether anyone interacts with the creative. CPC, on the other hand, bills only when a user clicks the ad, which merely indicates curiosity, not commitment. Both models leave the publisher bearing the risk: they pay for exposure or interest without any guarantee that the user will install, retain, or spend. Enter cost‑per‑action (CPA), also known as cost‑per‑acquisition.

CPA ties payment directly to a predefined, measurable outcome. "You only pay when the specific action you’ve agreed on occurs," Nagrani notes. "The definition of that action can evolve as the game moves through its lifecycle, and selecting the right action is a key discussion we have with each publisher before launching a campaign." Before a game’s launch, a CPA campaign might reward users for signing up to receive more information. There are two common opt‑in structures: single opt‑in (SOI), where the user simply submits their details, and double opt‑in (DOI), which requires the user to confirm via a verification email.

DOI costs more because it filters out less‑interested prospects, but it often yields higher conversion rates once the game goes live. The choice between SOI and DOI depends on the publisher’s confidence in their funnel and the expected quality of early interest. At launch, the most straightforward CPA metric is an install. However, experienced publishers rarely stop there.

They add qualification layers—such as requiring the player to survive to Day 1 (D1) or Day 7 (D7) retention, or to complete the tutorial—so that the payment is for a retained user rather than a mere download. This distinction is crucial for live‑service games, where the install is merely the first step in a longer monetisation journey. As the game matures, CPA campaigns can target deeper funnel actions, such as a player’s first in‑game purchase. Naturally, the cost per conversion rises the further down the funnel you go, because you are buying greater certainty.

"The trade‑off is always the same: the more certain the outcome, the higher the price, and sometimes volume becomes harder to achieve," Nagrani says. Because CPA aligns directly with a game's LTV, publishers can model how much they are willing to spend to acquire a player. If data shows that a registered user is worth $30 over a 90‑day period, the CPA payout can be set so that the acquisition cost fits within the desired payback window. This predictive approach contrasts sharply with CPM or CPC, where advertisers buy exposure or clicks and hope the downstream funnel behaves as expected.

Another advantage of CPA is risk sharing. With CPM or CPC, the publisher pays regardless of whether the targeting or creative is effective; the risk sits entirely with the advertiser. CPA flips that dynamic: the marketing partner only earns when a qualified conversion occurs, giving both sides a shared incentive to optimise the campaign.

"When the advertiser and the agency are looking at the same conversion numbers, collaboration improves, and we both benefit from fixing any issues," Nagrani explains. Nevertheless, CPA is not a universal cure.

It works best when the underlying game is of sufficient quality to attract and retain players. No pricing model can rescue a poorly designed product.

Moreover, CPA requires robust analytics and a clear definition of the target action, as well as the ability to track that action accurately across platforms. When executed correctly, CPA distributes risk evenly between the developer/publisher and the acquisition partner. Both parties profit only when the agreed‑upon outcome is achieved, encouraging continuous testing of traffic sources, creative assets, regional performance, and audience segments.

If a particular region underperforms or an ad creative fails to communicate the game's value, both sides have a financial motive to investigate and iterate. In summary, CPA has become the preferred UA model for top free‑to‑play PC publishers because it directly ties spend to measurable outcomes, aligns with lifetime‑value calculations, and fosters a collaborative, risk‑balanced relationship between advertisers and marketers.

As Nagrani succinctly puts it, "CPA is a win‑win model for game publishers and us. We win only if they win." For more information about PWN Games and its conversion‑driven performance‑marketing services for PC games, visit pwngames.com.
