Paid ads can put your app in the spotlight, but if your website doesn't convince, you lose downloads before anyone even reaches the store.
How Your Website Generates More App Downloads Than Paid Ads
If you want to organically increase app downloads, you need to look beyond media budget alone. A strong website funnel and a smart landing page help you move visitors toward download faster, make conversion optimization tangible, and better demonstrate how to prove ROI from website-driven app acquisition.
1. Want more organic app downloads? Start on your website
Many app owners chase mainly ads, but the biggest opportunity is often already right in front of you. According to Branch.io, based on Apple data, 65% of app downloads start organically in the App Store. Paid ads capture 10% of downloads, and off-store unpaid another 15%. This is exactly where your website funnel comes in. Adjust sees an average 50/50 split between paid and organic, but this varies significantly by category. So the question is: is your landing page already helping you get more organic app downloads? For example, is your download button immediately visible? If not, you're already leaving some conversion optimization on the table.
Does 15% of downloads being off-store unpaid sound small? Work backward from your current installs, and you'll see how much free growth through your site might be getting left behind. The pain often isn't in reach, but in a homepage that explains well but doesn't get people to download.
So take a practical approach. Create one dedicated app page with a short promise, a visible download button, and links to both stores. Also add 2 or 3 frequently asked questions, so doubts disappear right away. Does your page load slowly, or does someone have to search for the button? Then you're already losing people before the App or Play Store even comes into view.

2. Why paid ads and a website funnel together accelerate growth
Paid and organic strategies reinforce each other much more often than business owners think. Branch.io shows that paid installs boost organic downloads by an average of 1.5 times. On Android, this even went up to 16.6 to 17 organic installs per paid install. arXiv also saw this effect: when GameSpace stopped advertising, organic installs dropped by 18 to 30%. What does that mean for you? Your website funnel isn't a side issue, but the accelerator. A strong landing page warms up visitors and extracts more value from every campaign. Try briefly pausing your campaigns, and you'll see the real indirect effect of your campaigns.
Most companies still look at paid as if it were an isolated channel. Meanwhile, a single shutoff test (a pause) often already shows whether campaigns are secretly also pushing up your organic installs. If you only steer on last-click, you're probably already underestimating your growth engine by months.
Make your website the fixed intermediate step from campaign to download. Don't send ad traffic blindly to the store, but first to a page that matches the ad exactly. Test this per target audience or region. Do you see organic installs rising along with it? Then you know your campaigns are doing more than just generating direct clicks.

3. How to make your landing page convert better into app downloads
Your website doesn't have to be an online business card. It has to deliver app downloads. So align your content with the search intent that also exists in the store. Branch.io reports that 65% of downloads start with a search, so your landing page needs to answer that question directly. Then make the step to downloading as small as possible with deep linking. Also show social proof: real reviews, screenshots, and a short demo. This way, your website funnel feels logical, fast, and trustworthy. That's exactly what lifts conversion optimization in the Dutch market.
Although at JOIN Cycling we primarily worked with Custom Product Pages in the App Store, we saw exactly what intent-match does: CPI dropped from €10.70 to under €6, and visibility increased by 1300%. If your landing page tells everyone the same thing, you're probably leaving that same gain on the table.
Keep it simple for visitors. Give each target audience its own landing page, use the same words they're searching for, and show right away what the app solves for them. Add 3 reviews, a short demo, and a smart link to the right store page. Less doubt, fewer clicks, more chance of a download.

4. How to prove ROI of website driven app acquisition
How do you prove ROI of website-driven app acquisition? Not just based on last-click, but with smart measurement. The arXiv study on GameSpace found 7.5% extra effectiveness above standard paid attribution, precisely because organic impact often stays out of view. So set up UTM parameters on all store links from your website and connect your data to tools like Branch, Adjust, or another tool. Then compare your organic app downloads during a short shutoff test. Do you see overlap between Search Console and store keywords? Then your website funnel and landing page are reinforcing each other. That's sustainable growth, without leaning blindly on ads.
This is often where it goes wrong: paid looks profitable, organic looks free, and your website sits somewhere in between without getting any credit. If research already sees 7.5% extra effect above standard attribution, how much impact are you currently missing in your own reporting?
As mentioned earlier, growth here doesn't come from one isolated button or one campaign. By combining a strong landing page, smarter campaigns, and better measurement, you turn your website into a real acquisition channel. Start small: set up tracking properly, improve your app page, and test per target audience. That's exactly what gives you more grip on downloads, budget, and predictable growth.
