How to Lower Your Cost Per Install on Apple Search Ads

If you’re running Apple Search Ads and struggling with high acquisition costs, you’re not alone. Many indie app marketers face the same problem. But what if there was a simple formula that could not only lower your cost per install (CPI) but also scale your campaigns profitably?

In this post, you’ll learn:

  • How to calculate your ideal Cost Per Tap (CPT)

  • Proven tactics to scale your campaigns

  • Actionable tips you can implement today

Let’s dive right in!

The Magic Formula: How to Decrease Your Cost Per Install

First, here’s the simple formula that has helped many clients cut their cost per install without sacrificing volume:

Cost Per Tap (CPT) = Target Cost Per Acquisition (CPA) × Conversion Rate

Example:

  • Target CPA = $2

  • Average Conversion Rate = 40%

  • Ideal CPT = $2 × 0.4 = $0.80

Action Steps:

  • Start with a reasonable CPA (e.g., $2).

  • Set initial CPT based on average conversion rates (typically 30%-40% for exact match campaigns).

  • Optimize weekly based on real campaign data.

Pro Tip:
If your actual conversion rate exceeds expectations, increase your CPT slightly to gain more visibility without overspending.

5 Proven Ways to Scale Your Apple Search Ads Campaigns

Once you’ve got your CPI under control, here’s how you can scale profitably:

1. Increase Your Conversion Rate

  • Optimize your onboarding flow and pricing pages.

  • Run A/B tests on your app store creatives (screenshots, icons).

  • Improve your in-app purchase flow to maximize revenue per download.

2. Expand Your Keyword List

  • Think beyond obvious keywords.

  • Explore related terms or complementary apps (e.g., if your app helps with focus, target “Slack” users or other productivity apps).

  • Use keyword tools and Apple’s suggestions to find hidden gems.

3. Adjust Your CPA and CPT Strategically

  • If your revenue per user increases, you can afford a higher CPA, leading to greater reach.

  • Keep recalculating your ideal CPT weekly using the formula.

4. Add More Geographies (Geos)

  • Expand into top-performing countries where your app resonates.

  • Set up one campaign per geo to better track and optimize performance.

Quick Setup Tip:
Duplicate your U.S. campaign, update the country targeting, adjust CPT if necessary (some geos have lower conversion rates).

5. Set Up Retargeting and Cross-Promotion Campaigns

  • Target returning users to re-engage them.

  • Cross-promote your other apps within your portfolio to maximize lifetime value (LTV).

Bonus:
Experiment with Search Tab Campaigns (ads on the App Store search page) — but be cautious. Current targeting is limited and CPAs tend to be high.

Common Mistakes to Avoid

  • Setting and Forgetting Bids: Update your bids weekly based on performance.

  • Ignoring Conversion Rates: A higher CPT is okay if your conversion rate justifies it.

  • Neglecting New Keywords: Always be expanding your keyword list to keep scaling.

  • Skipping Retargeting: Don’t just focus on new users—bring back the ones who showed interest!

Apple Search Ads is one of the most powerful user acquisition channels — if you know how to play it smart.
By applying the simple CPT formula, optimizing your keywords, and methodically scaling your campaigns, you can lower your CPI and massively grow your app.
