No paid acquisition channel is universally the strongest for subscription products or lead generation. The right starting point depends on where your users are, whether demand for your product already exists, how much creative you can produce, and what your measurement setup can reliably track. This guide covers Meta, TikTok, Google Search, Google App Campaigns, and Apple Search Ads — how each works and how to decide which to prioritise.
Demand capture vs. demand generation
The most important distinction in channel selection is not which platform is "better" — it is whether your potential users are already searching for a solution, or whether you need to interrupt them and create the desire.
Demand capture channels (Google Search, Apple Search Ads) reach people actively looking for what you offer. They convert efficiently when sufficient search volume exists, but you cannot scale beyond the available intent. If few people search your category, the volume ceiling is low regardless of budget.
Demand generation channels (Meta, TikTok, Google App Campaigns via YouTube and Display) interrupt users who were not looking. They can reach far larger audiences, but require compelling creative to earn attention and more persuasion before a user converts. They are how you build demand, not only capture it.
Most businesses eventually need both. The question is which to prioritise first, given your category awareness, budget, and creative capacity.

Meta (Facebook and Instagram)
Read our deep-dive on Meta Ads for digital products in 2026 for the full picture.
Strengths
- Broad reach across most markets, demographics, and age groups
- Mature optimization for purchase and subscription events when sufficient conversion data is available
- Flexible creative formats across feed, Stories, and Reels
Weaknesses
- iOS measurement is significantly impacted by ATT; reported attribution uses modeled data, not exact user-level tracking
- Creative fatigue is constant — the channel rewards a steady supply of fresh concepts, not only variations on existing ads
- Performance is more variable for products with limited conversion history or narrow target audiences
Use it when: you have conversion tracking in place and can produce new creatives regularly. For many subscription products and lead-generation businesses, Meta is a strong candidate for the primary acquisition channel — but validate that for your specific product, audience, and market rather than assuming.
TikTok
See why most teams fail on TikTok ads — and what's actually different about the platform.
Strengths
- Lower CPMs in many markets, though these vary by region, category, and seasonality
- Rewards native, entertaining content — UGC and creator-style video tends to outperform polished formats
- Audience is broader than it was two years ago, though under-35s remain the strongest segment in most markets
Weaknesses
- High creative volume is the operating cost of the channel — native-feeling video at regular cadence is a baseline requirement, not an optional upgrade
- Optimization for deep conversion events (subscriptions, purchases) typically needs more event volume than Meta before it stabilises
- Running TikTok with Meta-style assets or targeting is the most common reason it underdelivers
Use it when: you can supply native-format short video regularly, your product can be demonstrated or explained quickly, and you're prepared for a longer ramp to conversion-level efficiency. For TikTok advertising, we grew one client's account from zero to one of their top three acquisition channels across 12 European markets.
Google Search
Strengths
- Reaches users at the moment they are actively searching for a solution — the highest commercial intent of any channel covered here
- Lower creative demand compared to paid social; copy and landing page quality are the primary levers
- Works for web products and apps where meaningful search volume exists
Weaknesses
- Volume is capped by search demand in your category — you cannot spend your way to more intent than exists
- Broad match and automated campaign settings can allocate budget to irrelevant queries without active negative keyword management
- Cost per click in competitive categories can be high; strong landing page conversion is required for the economics to work
Use it when: people already search for your product category or for the problem you solve. Keep match types tight (exact and phrase) with a maintained negative keyword list, and review search term reports regularly. Google Search pairs well with Meta — one captures existing intent, the other builds it.
Google App Campaigns
Google App Campaigns (previously Universal App Campaigns) are distinct from Google Search and should be evaluated separately. They run across multiple Google properties — Search, YouTube, Google Display Network, and Google Play — with placement determined by the algorithm rather than the advertiser.
Strengths
- Can reach users across different intent states: active search (Google Search), video engagement (YouTube), and passive browsing (Display and Play)
- Well-suited to driving app installs and in-app events at scale on both Android and iOS
- The algorithm mixes text, image, and video assets across placements — a broad surface for creative signal
Weaknesses
- Limited advertiser control over placements — the algorithm decides where budget is allocated within the campaign
- Harder to diagnose performance by placement than with manually structured campaigns
- iOS attribution is subject to the same SKAdNetwork limitations as other channels
Use it when: you are primarily growing a mobile app and want to reach users beyond those actively searching. Useful alongside Apple Search Ads (for iOS App Store intent) or Meta (for social-feed discovery), particularly for Android-first or cross-platform apps.
Apple Search Ads
Strengths
- The highest-intent placement for iOS app installs: users are searching inside the App Store for your category or brand
- Apple's own Campaign Analytics reporting is native and does not depend on SKAdNetwork for its own dashboard, making it more transparent than third-party channel reporting; however, MMP integration (via Apple's AdServices framework) is still required for attribution in your own analytics stack
- Strong trial and subscription rates in many app categories, particularly when the App Store product page is well-optimised
Weaknesses
- iOS apps only — no web, SaaS, or Android coverage
- Volume is capped by App Store search demand in your category
- Competitors can bid on your brand terms; brand keyword defence may be necessary
Use it when: you have an iOS app with meaningful category or brand search volume in the App Store. App Store product page optimisation and ASA are interdependent — a stronger product page lifts both organic and paid conversion. Learn more about mobile app marketing.
Snapchat (honourable mention)
Useful for specific younger demographics and in markets where Snapchat usage remains significant (the US, UK, France, and several MENA markets in particular). Usually a third or fourth channel to test once primary channels are stable and creative operations are established.
Choosing a channel: a framework by context
| Product type | User intent | Creative capacity | Suggested starting point |
| iOS subscription app | Users search App Store for the category | Any | Apple Search Ads — capture existing intent first |
| iOS subscription app | Limited App Store search; broader awareness play | Medium–high | Meta — demand generation with creative |
| Android or cross-platform app | Any | Medium | Google App Campaigns or Meta |
| Web subscription / SaaS | Category searches exist | Low–medium | Google Search — capture existing demand |
| Web subscription / SaaS | New category; low search volume | High | Meta or TikTok — build demand first |
| Lead generation | Commercial intent in Search | Low–medium | Google Search or Meta |
| Any product, first campaigns | Any | Any | One channel — prove it before adding more |
These are starting points based on common patterns, not universal rules. A product with a strong existing community may find TikTok outperforms Meta from the outset. A B2B product may find LinkedIn more relevant than any channel above. Test your assumptions with a defined budget rather than committing based on category norms.
How to allocate budget across channels
Fixed percentage allocations across channels are rarely the right approach. What makes sense depends on how many channels you are running, how mature each one is, and what you are currently trying to learn.
A more useful framing:
- Define a test budget and a success threshold before launching a new channel. Decide in advance how much you will spend, over what period, and at what cost per acquiring subscriber or lead the channel would be worth continuing. This prevents both exiting too early and running indefinitely without signal.
- Give your primary channel enough budget to optimise. Ad platforms need a minimum conversion volume to exit the learning phase. Spreading budget too thinly across channels means none of them accumulate enough data to perform efficiently.
- Reallocate on outcomes, not inputs. As cohort data matures, move budget toward channels where cost per paying subscriber or qualified lead is within your target — not based on which channel generated the most clicks, installs, or impressions.
Reassess channel allocation when you have meaningful cohort data, not on a fixed calendar schedule.
FAQ
Which channel is cheapest?
Cheapest per click is rarely cheapest per customer. Compare channels on cost per paying subscriber or cost per qualified lead, using cohort data once it's available — not initial CPMs or CPCs.
Can I run all channels at once?
You can, but with a limited budget you'll accumulate too little data on any single channel to optimise effectively. Starting with one or two and expanding once those are stable usually produces better outcomes than spreading thin.
Is TikTok only for young audiences?
TikTok's audience is expanding, but it's still strongest with under-35s in most markets. Whether it works for your specific product depends on your category — test with a defined budget rather than assuming it will or won't.
Do I need different creatives for each channel?
Yes. TikTok rewards native, fast-paced video that looks organic; polished production typically underperforms. Meta accepts a wider range of formats but still rewards authentic-feeling creative for cold audiences. Google Search and Apple Search Ads are copy and product-page led — very different requirements from paid social.
What is the difference between Google Search and Google App Campaigns?
Google Search captures users actively searching for your category or problem — high intent, limited by search volume. Google App Campaigns run across multiple Google properties (Search, YouTube, Display, Play) with placement determined by the algorithm. They serve different purposes, reach users in different intent states, and should be set up and evaluated as separate campaigns.
