Google Ads增强型应用投放：绕过GAC限制与SKAN的实操指南

Google Ads is one of the most underused channels in subscription app user acquisition. Not because the inventory is bad, but because the default way to buy it gives advertisers almost nothing to work with.

That default is Google App Campaigns (GAC, formerly UAC), and it has been the status quo for app advertisers for years.

Thomas Petit's practical guide to Google App Campaigns documents the limitations better than anyone:

• Valuable search inventory you can't pick keywords for
• No keyword reporting
• No way to run search-only campaigns
• Brand searches silently inflating your campaign performance

Thomas’s guide is the best resource for surviving within Google’s current restraints. But it’s a tight box. This article is about enhanced app campaigns — a new way to get out of the box.

Why do enhanced app campaigns matter most on Google?

In my previous article, I covered what enhanced app campaigns are and why apps are shifting budgets to them. Quick refresher: enhanced app campaigns (EACs) are web campaigns whose final URL redirects users straight to the app store. No landing page, no web funnel, no SKAN dependency.

This article is the execution manual for EACs — specifically focused on Google, because Google is where EACs unlock the most. On Meta and TikTok, running EACs mainly gets you better measurement and enriched signals. They’re valuable, but the campaigns themselves look similar to what you were running before.

Google is different. On Google, EACs unlock entirely new campaign types that don't exist for app advertisers:

• Search: bid on specific keywords and search terms, and see revenue and ROAS at the keyword level. GAC technically serves on search, but you don't choose the keywords, you don't see them properly, and you can't exclude them. It's by design.
• YouTube Shorts: get full control over placement types within YouTube. This use case is great for apps that mainly run vertical videos and want to access new inventory without creating new assets.
• Demand Gen: full control over how your budget is spent. If you have winning vertical video or static images from Meta or TikTok, this is a new home for it, same format.
• Display: the largest display network on the internet, with placement-level control.
• Performance Max (PMax): Google's all-inventory automation product, once your conversion signals are strong enough to feed it.

One important thing to note is that running enhanced app campaigns on Google Ads does not allow you to reach the Play Store inventory on Android devices. So this is a constraint you should keep in mind.

With GAC, Google's algorithm decides everything: placements, keywords, audiences, budget allocation. You upload assets, set a bid, and pray. With EACs, you're buying Google inventory the way web advertisers have for 20 years. With actual control.

Across the subscription apps I worked with, the numbers back it up:

• 100% reduction in install cannibalization — because you can now control all brand search terms (more on this below)
• 12% lower CPMs on Demand Gen EACs compared to equivalent GAC placements
• 14% higher ROAS on Demand Gen versus GAC targeting similar placements

Let's get into how it actually works.

Are enhanced app campaigns allowed on Google Ads?

I know this is the first thing on your mind. When we first started running enhanced app campaigns at Appstack, this concern came up a lot. The answer is a clear yes.

Enhanced app campaigns are web campaigns. When you run one, you're using Google Ads exactly as designed: a web campaign with a final URL, a click, and conversions reported back through Google's standard web measurement stack. The fact that your final URL redirects the user to the App Store or Play Store is not a loophole. Deep links and store redirects are a normal, documented part of the web. App stores are websites too.

There is no policy against it. You're not spoofing anything, hiding anything, or exploiting a bug. In my experience, thousands of apps run this structure at scale today, with Google account reps fully aware of it. Google gets paid either way. (And you could argue that they prefer it, because you feed their algorithm richer conversion data than SKAN ever could.)

So no, you won't get banned.

How it works under the hood

Before touching the Google Ads interface, understand the click journey — this is how app install attribution works without SKAN. It's five steps:

• User clicks your ad: the ad's final URL is a tracking link (app store page), not your website.
• Instant redirect: the link captures the click (with the Google click ID, campaign, keyword, and ad parameters) and redirects the user to the App Store or Play Store in milliseconds — the user never sees a webpage.
• Install and first open: the user installs the app and opens it for the first time. On first launch, the SDK matches the install to the click using probabilistic matching. It doesn't depend on SKAN or ATT opt-in.
• Events flow in: trial starts, subscriptions, renewals, and every event is tied back to the exact campaign, ad, and keyword that drove the install.
• Signals go back to Google: Conversions are uploaded to Google Ads via API against the original click ID. Google's algorithm now optimizes using previously-matched conversion data rather than modeled SKAN postbacks, which are aggregated and have long delays.

That last step is what makes the whole system compound. Google's bidding is only as good as the signals you feed it, and EAC signals are cleaner, faster, and more granular than anything SKAN can deliver.

For example, you can pass data back to Google Ads hourly and have total control over which signal is mapped to an offline conversion action. A lot of the apps I work with strategically prioritize qualified events, like ‘Trial qualified’, to improve performance.

Setting up your first enhanced app campaign on Google Ads

Step 1: Offline conversion actions

In Google Ads, create web conversion actions for the events you care about. For subscription apps, the standard set is:

• Install (secondary, for diagnostics, not optimization)
• Trial started
• Trial converted (or subscription started, if you don't offer trials)

Set ‘trial started’ or ‘subscription started’ as primary, depending on your volume. Same trade-off logic as everywhere else: more signals vs. better signals.

If you want to know which event to optimize or how much to spend, my answer is to do the math and ensure you get at least 10 conversions per campaign per day. So if your subscription costs $100 and you reach breakeven status (which is great at the beginning), you will need to spend $1,000 per day to meet the threshold.

Pro tip

Don’t get frustrated during your first few days optimizing towards an offline conversion action in Google Ads. It’s normal to struggle: Google lacks sufficient context to understand what the offline conversion action actually means. After feeding at least 25 conversions, the performance starts to improve.

A quick note on the numbers in this guide: ~10 primary conversions per campaign per day is the floor for learning to stabilize, around 25 conversions is when performance usually starts to improve, and 50 is the minimum before you judge a campaign or change its structure.

With the RevenueCat and Appstack integration, conversions are automatically uploaded to the Google click ID once the account is connected. You don't build any of this pipeline yourself. For a walkthrough, check out this integration guide.

Step 2: Create your tracking links

Running EACs is fully within Google's policies, but building your own tracking links requires Google certification which means a two/three month review of your infrastructure — that’s a long wait, so most teams use a certified partner instead (like us at Appstack).

The tracking link must include all query parameters to properly attribute the data and return the correct information to Google. This is an example of a link:
