To promote an app on Instagram, you need posts that show the app working and a link that takes each viewer to the right store for their phone. The second part is where most apps lose people. Captions are not clickable, Reels have no link field, and only the first of your five bio links shows on your profile, so part of your audience lands in a store their phone cannot use. This guide covers both parts and shows how to see which post, creator or ad actually brings the clicks.
Two stores, one visible link
On Instagram, the reliable places to tap a link are the links in your bio and the link sticker in stories. Everywhere else (captions, comments, Reels) a URL is plain text, and nobody retypes a store address from a caption.
That would be manageable if your app had one address. It has two. The bio does fit both store links, but only the first is visible on your profile; the second sits behind an extra tap. Put the App Store link first and every Android viewer who taps it lands on a page they cannot install from. Put Google Play first and the iPhone half of your audience gets the wrong store. A visitor who opens the full list has to work out which link is theirs, and a choice at that moment is where a lot of people stop.
The fix is an app download link: one URL that checks the device and sends iPhones to the App Store, Android phones to Google Play and desktop visitors to your website. The mechanics of the device check are covered in one link for the App Store and Google Play. For promotion, the point is simpler. The same link now works in every placement, and each Instagram placement has its own rules.
What to post: show the app doing one thing
People install an app after they watch it solve a problem they have. A logo animation does not show that. A screen recording does.
App reels that hold attention usually share a few habits. The first second shows the result, not the splash screen. One reel covers one feature, because a viewer who sees five features in fifteen seconds remembers none of them. And the phone screen fills the frame, since most people scroll with the sound off and the screen carries the whole message.
Formats worth rotating:
- Before and after: the slow way to do the task, then the same task in your app.
- A real use in under 15 seconds, recorded on a phone rather than a simulator.
- A reply to a comment. Someone asked "can it do this?" and the reel shows it doing exactly that.
- An update reel when you ship something your users asked for.
Every one of these ends with the same instruction: link in bio. That line only pays off if you know which link it is, and this is where most app accounts lose track.
Give every reel, creator and ad its own link
Instagram reports taps from inside the app as l.instagram.com. Your analytics see Instagram as one source, so a reel that sent 300 people and a reel that sent 4 look the same.
The workaround costs almost nothing. Create a separate short link for each thing you want to compare. All of them point to the same stores; only the ending changes:
linx.ly/myapp-reel-onboardinglinx.ly/myapp-creator1linx.ly/myapp-ad-october
Each link keeps its own click count, and on the Pro and Business plans you also see the country and device behind every click. The app link in your bio needs one extra habit. It is shared by every post on your profile, so it measures the account, not a single reel. When you push a specific reel for a week, put that reel's link in the bio for the week, and the clicks in that window belong to it.
Stories work the same way. The sticker has a quirk with long URLs, explained in link too long for an Instagram story.
Paying creators? Compare them on clicks
Creator deals are where separate links earn their keep. Without them, you pay three creators, watch installs rise slightly, and cannot say which of the three did it.
Give each creator their own link before the post goes live, and ask them to use it in their bio or story sticker. A week later you have three numbers side by side. The total is only the start, and on Pro and Business the report shows more:
- Country. A creator who sends 200 clicks from a country where your app is not released has sent you 200 people who cannot install it.
- Device. If your app is iOS only, Android clicks from a creator's audience are money spent on people who land on your fallback page.
- Timing. Clicks that stop after the first day point to a story. Clicks that keep arriving for a week usually mean a post people saved.
This is the data for the second round of deals. A creator with half the followers and twice the clicks is the cheaper one, whatever the rate card says.
iPhone or Android? Check the split before you spend
On the Pro and Business plans, the click report also splits visitors by operating system, which makes it a fair picture of who your Instagram audience is. Say eight out of ten clicks come from iPhones. That is a case for fixing the iOS onboarding bug first and pointing the next ad set at iPhone users. The opposite split means the Android build deserves more than whatever hours are left over.
Keep in mind that these are clicks, not installs: a tap on the link does not mean the person finished the download. App Store Connect and the Google Play Console report installs, and comparing those weekly numbers with your clicks gives a rough tap-to-install rate.
Set the link up before launch day
The worst moment to discover a wrong link is after the launch reel has gone out.
Both stores let you collect interest before release. Apple lets you list a new app for pre-order, and Google Play has pre-registration. Both use the listing's normal address, so a link you create today keeps working on launch day without any change. Put those URLs into the app link two or three weeks early and use it in every teaser. By launch day, the link in your bio has already been tested by real people.
If you are not listed yet and only have a waitlist page, give it a regular short link for the teasers, and create the app link as soon as the pre-order or pre-registration page exists.
Setting it up in Linxly
The whole setup takes a couple of minutes, and nothing gets installed in your app.
- Create a deep link and paste your App Store and Google Play URLs.
- Set a fallback page for desktop visitors. Usually that is your website.
- Pick a readable ending, such as
linx.ly/myapp, and put it in your bio. - Repeat with a new ending for each reel, creator or ad you want to compare.
- Use the QR code that every link gets automatically for anything offline: a poster at a meetup, a card at a conference table, the last frame of a reel.
Five bio links cover the app, a website and a support page. If you need more than that (a press kit, a promo, a newsletter), a bio link page keeps the app link next to them under one URL.
Frequently Asked Questions
How do I add an app download link to Instagram?
Open your profile, tap Edit profile, then Links, and add an external link. Use one link that sends each phone to its own store, so iPhone and Android visitors both land somewhere they can install from.
What should I post first to promote my app on Instagram?
A short screen recording of the one thing your app does best, with the result in the first second and filmed on a real phone. Put the app link in your bio before the post goes live, so the people it convinces have somewhere to tap.
Do I need to add an SDK or write code?
No. You paste your store URLs into the link, and the device check happens when someone opens it. Nothing goes into your app. This covers sending people to the right store; opening a specific screen inside the app is a different tool that does need an SDK.
How do I see which Instagram post brought the most clicks?
Instagram shows all taps from the app as one source, so give each reel, creator or ad its own short link. Each link then reports its own clicks, with country and device on the Pro and Business plans.
Can I track app installs from Instagram this way?
No. The link counts clicks, not installs. Installs are reported in App Store Connect and the Google Play Console, and comparing the two numbers gives you a rough tap-to-install rate.
How much does it cost?
Linxly starts at $0.99 a month and includes app links, short links with custom endings, QR codes and click analytics. There is a 7-day free trial, cancel anytime.
