If you run a mobile marketing program, you’ve already had this debate internally: Should you route users to your app or your website? The instinct is usually to push people toward the app. Apps convert at higher rates, drive more repeat purchases, and keep your brand top of mind. Once someone has your app installed, the relationship is fundamentally different.
But that instinct can cost you. The problem isn’t the app — it’s the timing. Interrupting a high-intent user with an install prompt is one of the most common ways brands introduce friction at exactly the wrong moment. Whether it’s a flash sale, a major campaign send, or a paid acquisition push, the users most likely to buy right now are also the users most likely to bounce when you ask them to stop and download something first.
The question isn’t “is routing to the app or web better?” It’s “when does each one serve the user better?” Here’s a framework for thinking through it.
Start with the value of what you’re giving up
Every time you show an install prompt, you risk losing a sale. You need to determine whether the long-term upside of gaining an app user justifies it.
Two numbers do most of the work: the lifetime value (LTV) difference between app users and web-only users, and your web average revenue per daily active user (ARPDAU) right now. If app users are worth significantly more over time, you can afford more friction. If the gap is narrow — or your traffic skews toward one-time buyers — you can’t.
The math changes based on context. During a routine week, a $200 LTV advantage for app users might easily justify losing some web conversions to install prompts. But during a major sales event or limited-time promotion, the composition of your traffic shifts. You’re seeing more deal-driven visitors who may never come back. The long-term value argument weakens. The immediate conversion opportunity gets more expensive to throw away.
There’s no universal answer here, but the direction is: The higher the immediate revenue opportunity, and the lower the repeat potential of that traffic, the less friction you should introduce.
Use this as a quick gut check before your next campaign:
| Push app installs | Prioritize conversions on web | |
| Traffic type | Organic, browse, loyalty | Promotional, retargeting, sales events |
| LTV gap (app vs. web) | Large | Small |
| Repeat purchase potential | High | Low |
| Current web ARPDAU | Low | High |
There are exceptions: If your app offers something your website genuinely can’t (augmented reality try-ons, deep personalization, loyalty perks that unlock immediately), the install prompt can earn its place even against high-intent traffic. But for most brands in most moments, the table above is a reliable guide.
How Stadium Goods cracked the routing problem
Stadium Goods, a premium sneaker and streetwear marketplace, ran directly into this problem while optimizing its email program.
After migrating to a new platform, the team prioritized app growth by routing all email traffic, regardless of whether the recipient already had the app, to a download screen. Early on, it worked. App installs ticked up. But after a few months, the lift flatlined. It’d reached the users who were ready to download. Everyone else was just hitting a wall between their inbox and a purchase.
Working with Branch, the customer relationship management (CRM) team tested a different holiday season approach: Send existing app users directly into the app via deep links, and send everyone else to the mobile web with a lightweight download banner. No full-screen prompts, and no detour through the app store for someone who just wanted to buy a pair of Jordans.
Email revenue picked up immediately. As CRM manager Matt Tompkins put it, the change “removed friction and met customers where they were.” That adjustment — routing users based on where they actually were rather than where the team wanted them to go — held steady through the rest of the year, including its biggest sales period, when Stadium Goods saw email revenue jump 268% year over year.
The installs didn’t disappear. The banner still converted users who were open to downloading. But those users came in on their own terms, without friction blocking the users who just wanted to check out.
Routing rules of thumb
The brands doing this well aren’t making a single decision about app vs. web. They’re making a dynamic one, based on who the user is and where they are in the journey. Following these directives will help you navigate these scenarios:
- Existing app users should always deep link into the app. No exceptions.
- Non-app users coming from high-intent traffic — promotional emails, retargeting ads, limited-time offers — should go to mobile web first, with a nonintrusive banner for users who want to download.
- You should reserve full install prompts for lower-pressure moments: organic browse sessions, loyalty program touchpoints, post-purchase flows.
- Return visitors should get more aggressive calls to action (CTAs). Someone on their second or third visit has already shown repeat intent — that’s your cue to make a stronger case for the app.
- Save your strongest install CTAs for after the purchase, when you’ve already established trust.
App growth and conversion rate optimization aren’t in conflict. They’re just sequenced. Close the sale first, then build the relationship.
