The landscape of game marketing has evolved dramatically over the past few years. In the early days, studios could simply buy ad space, hope that enough eyes saw their banners, and count on sales to follow. 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‑school tactics of buying impressions or clicks no longer deliver the results publishers need.
Amit Nagrani, who leads business development and client success at PWN Games—a performance‑marketing agency celebrating its tenth anniversary—points out that many PC publishers still cling to traditional awareness‑driven campaigns. These campaigns typically involve brand‑building 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 titles that rely on pre‑launch hype and wishlist generation, they fall short for live‑service games that must attract a steady stream of new players long after launch. "With premium games, the purchase is the whole thing," Nagrani explains.
"The spend goes heavily into awareness and consideration through the pre‑launch window, building recognition and wishlists, and then UA kicks in hard at launch as a boost. That's a sensible way to do it, because once someone buys and installs, the revenue is in." In contrast, free‑to‑play live‑service titles operate on a completely different revenue model. The initial install is merely the first step; the real money comes from keeping players engaged and eventually converting them into paying customers. Because these games need a continuous influx of users over months or even years, the traditional model of front‑loading marketing spend and expecting a quick payback no longer fits.
Historically, PC user acquisition (UA) relied on cost‑per‑mille (CPM) and cost‑per‑click (CPC) pricing. CPM charges advertisers for every thousand times an ad is shown, regardless of whether anyone interacts with it. CPC, on the other hand, only charges when a user clicks the ad, which at best signals curiosity but not intent. Both models place the financial risk squarely on the publisher: if the creative is off‑message or the targeting is poor, the publisher still pays.
The third, increasingly popular model is cost‑per‑action (CPA), also known as cost‑per‑acquisition. CPA only triggers a payment when a predefined action occurs—whether that action is a sign‑up, an install, a day‑one retention milestone, or a first in‑game purchase.
"You pay when a defined 'action' happens, and you choose which 'action' that is," Nagrani says. "It moves as the game moves through its lifecycle, and choosing it well is an important conversation I have with a game publisher before we go live." Before launch, a CPA campaign might target "opt‑in" events. A single opt‑in (SOI) counts when a player submits their email or other contact details.
A double opt‑in (DOI) adds a verification step, ensuring the lead is genuinely interested; DOI costs more but typically yields higher quality leads that convert more reliably at launch. The choice between SOI and DOI depends on the publisher’s confidence in its funnel and how much they value early‑stage conversion quality.
At launch, the most common CPA trigger is an install, but seasoned publishers rarely stop there. They add qualification layers—such as requiring the player to reach day‑one (D1) or day‑seven (D7) retention thresholds, or to complete the tutorial—so that the payment reflects a player who has demonstrated at least minimal engagement. This approach aligns spend with outcomes that matter for a live‑service title, where a mere download is only the entry point.
As the game matures, CPA can be tied to deeper actions like a first in‑game purchase, a subscription sign‑up, or any other monetisation event. Naturally, the cost per conversion rises as the funnel narrows: the more valuable the action, the higher the price the publisher is willing to pay. "The trade‑off is always the same: the further down the funnel you buy, the more certainty you're paying for, and certainty is never free," Nagrani notes. One of the strongest arguments for CPA is its direct connection to a game’s lifetime value (LTV).
When a publisher knows that a registered player is worth, say, $30 over a 90‑day period, they can set a CPA bid that fits comfortably within their payback window. This makes return on ad spend (ROAS) predictable from day one, rather than a hopeful guess after months of data collection. CPM and CPC lack this direct tie to revenue, leaving publishers to hope that clicks and impressions eventually translate into paying users. Risk distribution is another key benefit.
Under CPM or CPC, the publisher bears the full risk of poor targeting or ineffective creative. With CPA, the marketing partner only gets paid when a qualified conversion occurs, giving both parties a shared incentive to optimise the campaign. "On CPM or CPC, if the targeting is off or the creative isn’t landing, the publisher still pays," Nagrani says.
"With CPA, we’re only paid when a qualified conversion happens, so we have the same reason to find out what’s wrong as they do." That shared risk does not mean CPA is a silver bullet for every title. It works best when the underlying game is of sufficient quality to attract and retain players. No pricing model can rescue a poorly designed or unengaging experience.
However, for games that meet a baseline of quality, CPA aligns the economics of the publisher and the acquisition partner, encouraging continuous testing, creative iteration, and audience refinement. In practice, this means the acquisition partner must monitor everything—from traffic source performance to regional variations, from creative resonance to retention metrics. If a particular audience shows high install rates but low day‑seven retention, the partner will adjust targeting or creative to improve the qualified conversion rate, because their revenue depends on it.
In summary, CPA has become the preferred UA model for top free‑to‑play PC publishers because it ties spend directly to outcomes, aligns with LTV calculations, and distributes risk evenly between publisher and marketer. While it demands higher per‑action costs and more sophisticated campaign management, the payoff is a clearer, more predictable ROI and a collaborative partnership that benefits both sides.
As Nagrani 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.
