What is user acquisition?
User acquisition (UA) is the paid side of mobile growth — advertising your app to
buy installs from real users, across Apple Search Ads, Google App Campaigns and paid
social. Unlike organic ASO, which earns installs for free from store search, UA
pays per tap or per install. Done well it isn’t measured on headline cost per install
but on blended ROAS and the in-app value each cohort actually returns.
What is Apple Search Ads and how does it work?
Apple Search Ads is Apple’s advertising platform for the App Store. You bid to appear
at the top of relevant App Store searches (and other placements), paying per tap. It’s
the highest-intent paid channel on iOS — you reach people already searching for what
your app does, which is why we point it at the exact keywords your ASO has already
proven convert. Campaigns are split into discovery, exact and broad structures, with
negative keywords to stop them cannibalising each other.
Apple Search Ads vs Google App Campaigns
They solve different problems. Apple Search Ads captures high-intent iOS demand
on keyword search, billed per tap. Google App Campaigns (Google Ads for apps)
run automated, signal-driven placements across Search, Google Play, YouTube and the
display network on both platforms, billed toward a target CPI or action. Neither is
“better” — we run both, plus Meta and TikTok for prospecting and creative-led
discovery, and let each channel do the job it’s best at. The comparison table above
summarises the mix.
Is paid user acquisition worth it?
Paid UA is worth it once an install is reliably worth more than it costs — which you
only know by measuring in-app value, not installs. Cost per install varies enormously
by category and geo, so a single benchmark number is misleading; what matters is
payback and ROAS. Strong ASO changes the maths: it lowers the organic-carried base so
every paid install gets cheaper on a blended basis. We size a controlled test budget
against your economics before recommending scale — no burning spend to “see what
happens”.
How ASO and UA compound
Organic and paid are one loop, not two budgets. Organic proves which intent and
creative angles convert; paid scales that proven demand at volume; the resulting
install velocity sends ranking signal back to organic, which lowers cost per install
again. Running App Store Optimization and UA
together is what turns growth from a line item into a compounding system.
Choosing a user-acquisition agency
Look for a UA agency that reports on blended ROAS and in-app value rather than cheap
installs; that runs a real creative-testing engine, since creative is now the biggest
lever; that models SKAdNetwork and MMP attribution honestly; and that connects paid to
your organic ASO instead of running it in a vacuum. That’s the acquisition system
Appogean operates — evidence first, scale second.
