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 (F2P) live‑service games, and the old‑school tactics no longer deliver the results needed to sustain a title over months or years. Amit Nagrani, who leads 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‑driven campaigns. These campaigns rely heavily on brand pushes, creator 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 fall short for live‑service F2P titles that depend on a continuous flow of new players and ongoing monetisation. "With premium games, the purchase is the whole thing," Nagrani notes.
"The spend is front‑loaded on awareness and consideration before launch, building wish‑lists and brand recognition. Once the game ships, a burst of acquisition helps hit the initial sales target, and the revenue is essentially secured." In contrast, live‑service games require a steady stream of users long after launch.
"You can’t just ride a launch wave and call it a day," he adds. "You need players arriving week after week, month after month, and you must keep them engaged long enough for them to convert into paying customers.
The revenue comes from those conversions, not from the initial install." Traditional acquisition models—cost‑per‑mille (CPM) and cost‑per‑click (CPC)—are increasingly mismatched with this reality. CPM charges advertisers for every thousand times an ad is shown, regardless of whether anyone interacts with it. CPC, on the other hand, charges only when a user clicks, but a click merely signals curiosity, not intent to play or spend. Both models place the financial risk squarely on the publisher, who must hope that the downstream funnel will deliver enough revenue to cover the upfront spend.
Enter cost‑per‑action (CPA), also known as cost‑per‑acquisition. CPA ties payment to a clearly defined user behaviour—be it signing up for a newsletter, installing the game, reaching a certain retention milestone, or making an in‑game purchase. "You only pay when the agreed‑upon action occurs," Nagrani explains.
"That action can shift as the game moves through its lifecycle, which makes CPA a flexible tool for both pre‑launch hype and post‑launch growth." Before launch, a CPA campaign might reward users for opting in to receive updates. There are two common opt‑in structures: single opt‑in (SOI), where a user simply submits their email, and double opt‑in (DOI), where the user must confirm via a verification email. DOI costs more because it filters out less‑committed prospects, but it typically yields higher conversion rates once the game goes live. The choice between SOI and DOI hinges on the publisher’s confidence in their funnel and the expected quality of the leads.
At launch, the most straightforward CPA metric is an installation. However, seasoned publishers rarely stop there. They often layer additional qualification criteria—such as requiring the player to survive to day one (D1) or day seven (D7) of gameplay, or to complete the tutorial—so that the payment is tied to a user who has demonstrated at least minimal engagement.
This nuance is crucial for live‑service titles, where a mere download is only the first step toward monetisation. Beyond the install, CPA can target deeper funnel events like a first in‑game purchase. Naturally, the cost per conversion rises as the action moves further down the funnel because the advertiser is buying greater certainty.
"The trade‑off is always the same: the farther down you go, the more you pay for confidence, and confidence isn’t free," Nagrani says. "Volume can also become harder to source at those higher‑value actions." One of the strongest arguments for CPA is its alignment with a game’s lifetime value (LTV).
When a publisher knows, for example, that an average paying player generates $30 over a 90‑day period, they can set a CPA bid that ensures the acquisition cost stays within a profitable pay‑back window. Unlike CPM or CPC, where the connection to LTV is indirect and speculative, CPA directly ties spend to the outcome that the LTV model predicts.
This alignment also reshapes risk distribution. Under CPM or CPC, the publisher bears the risk: if targeting is off or creative underperforms, the advertiser still pays. With CPA, the marketing partner only gets paid when a qualified conversion occurs, giving both parties a shared incentive to optimise targeting, creative, and overall strategy.
"Both sides are looking at the same number, which fosters a more collaborative relationship," Nagrani observes. Nevertheless, CPA is not a universal cure. It works best when the underlying product is of sufficient quality to attract and retain users. A poorly designed game cannot be rescued merely by a smarter pricing model.
CPA merely ensures that the financial risk is shared and that both the publisher and the acquisition partner are motivated to troubleshoot issues—whether they stem from traffic sources, creative messaging, regional performance disparities, or mismatched audience expectations. In practice, a CPA partnership means continuous testing and iteration. The agency must monitor which traffic sources deliver the highest‑quality users, adjust creative assets to better convey the game’s value proposition, and fine‑tune regional budgets to exploit strong markets while mitigating weak ones. Because the agency’s revenue depends on successful conversions, it has a vested interest in solving the same problems the publisher faces.
In summary, CPA has become the preferred acquisition model for top PC free‑to‑play publishers because it directly ties spend to measurable, revenue‑generating actions, aligns with LTV calculations, and distributes risk evenly between advertiser and agency. While it is not a silver bullet for every title, when combined with a solid product and a data‑driven strategy, CPA provides a transparent, performance‑focused pathway to sustainable growth.
