There is no single price for Roblox user acquisition. What you actually pay per player depends less on the ad rate and more on two things you control: how well your thumbnail converts, and how well your game keeps the players it buys. Get those wrong and cheap traffic turns expensive fast.

Raising QPTR by 70% to 180%, as Indigo has on portfolio games, cuts effective acquisition cost more than any bid optimization.

What drives Roblox UA cost?

Two inputs set your real cost per player: the channel you buy from, and your game's ability to convert and keep the players it brings in. Paid placements like Roblox ads buy impressions at a headline rate, but an impression is not a player.

Whether it becomes one depends on your thumbnail click-through and your new-player experience. A game with a weak thumbnail pays for traffic that bounces, so its effective cost per player can run several times the rate it thinks it is paying.

Paid vs UGC traffic

Paid traffic, meaning Roblox ads and sponsored placements, is fast and predictable. You turn it on, impressions arrive, and you can scale spend the same day.

UGC traffic on YouTube and TikTok costs less per impression and often converts well, because a creator's audience arrives pre-sold. It compounds more slowly and is harder to switch on at will. Most games that scale run both: paid to move fast, creators to lower the blended cost over time.

Why QPTR changes your real cost

QPTR (qualified play-through rate) is the share of players who see your game in home recommendations and click through to play. It sits between every impression you buy and every player you get, so it sets your true cost per player.

Lift QPTR and the same ad budget delivers more players at a lower effective rate, and the gain shows up across millions of impressions. On portfolio games, Indigo has raised QPTR by 70% to 180% through thumbnail and audience work, which moves acquisition cost more than tuning bids ever does.

When to scale spend (and when not to)

Scaling spend works once two numbers are healthy: QPTR and D1 retention. Until then, more budget pushes more players into a funnel that leaks them. The order is simple:

  1. Fix the thumbnail so bought traffic converts (QPTR).
  2. Fix the first session so new players stay (D1 retention).
  3. Then scale spend behind a funnel that holds.

Pouring budget into a leaky funnel is the fastest way to make UA look expensive.

Measuring UA against ARPDAU

The number that matters is the ratio between what a player earns you and what they cost to acquire. Indigo treats UA as one input in a loop with monetization, aiming for a positive ARPDAU-to-acquisition ratio rather than the lowest cost-per-install.

A higher cost per player is fine when those players monetize and stay. A cheap player who leaves on day one returns nothing. Judge acquisition by what it returns over a player's lifetime.
