Before getting into individual platforms, it is worth understanding the starting point for most in-app sharing: the native share sheet.<\/p>\n\n\n\n
On iOS, the system share sheet is triggered by The native share sheet is your best default option because:<\/p>\n\n\n\n To trigger it effectively, you need to pass three things: the URL to share, a plain-text description, and (on some platforms) an image or thumbnail. For referral programs, the URL should be a tracked deep link with the referrer's ID embedded as a parameter.<\/p>\n\n\n\n On iOS, see Apple's UIActivityViewController documentation<\/a> for the full API. On Android, see the Android developer guide on sharing content<\/a>.<\/p>\n\n\n\n WhatsApp is the highest-volume sharing channel for referral programs in most markets outside North America. In regions like Latin America, Southeast Asia, India, and Europe, WhatsApp is often the primary communication layer.<\/p>\n\n\n\n WhatsApp renders link previews using Open Graph tags<\/a> from the linked URL. When a user pastes or sends a link in WhatsApp, the app fetches the page, reads the For referral links that pass through a redirect (which they typically do for tracking purposes), the redirect destination needs to have proper OG tags. The og:image should be at least 300×200 pixels; WhatsApp recommends 1200×630 for best rendering across devices.<\/p>\n\n\n\n WhatsApp does not support tracking pixels or JavaScript execution in link previews, so the preview rendering is static. Make sure the og:image loads fast (under 500ms ideally) or WhatsApp will skip it and show a text-only preview.<\/p>\n\n\n\n For sharing directly into WhatsApp from your app, you can use the WhatsApp share URL scheme<\/a>: Instagram Stories present a specific challenge: regular users cannot add tappable links to Stories directly. The swipe-up link feature that existed for accounts with 10,000+ followers was replaced by the link sticker, which is now available to all accounts.<\/p>\n\n\n\n What this means for referral programs: your users can share a referral via the link sticker in Stories, but it requires them to manually add the sticker after opening Instagram Stories from your app.<\/p>\n\n\n\n The better approach for Instagram is to make the sharing visual. Provide a branded image or graphic that users can share to their Story. The image should include a QR code that encodes the referral link. When someone viewing the Story scans the QR code (using their camera app), they land on the referral link with full attribution intact.<\/p>\n\n\n\n You can also support Instagram Direct Messages, where link previews do render. If your user base skews toward DM sharing rather than Story sharing, the standard OG preview approach applies.<\/p>\n\n\n\n For apps targeting Instagram-heavy audiences, consider building a "share to story" flow that generates a custom branded image with the user's referral code visible, makes it easy to save to their camera roll, and guides them to share it. This is more work but produces significantly better visual content than a plain link preview.<\/p>\n\n\n\n Twitter\/X renders link previews using a combination of Twitter Card meta tags and Open Graph tags. For referral sharing on Twitter, you want to use the Twitter link previews are a significant share of what makes a tweet visually compelling. A referral tweet with a large product image or branded graphic gets substantially more clicks than a plain text tweet with a raw URL.<\/p>\n\n\n\n Twitter-specific meta tags to include on your referral link landing page:<\/p>\n\n\n\n See the Twitter Cards documentation<\/a> for the full specification.<\/p>\n\n\n\n One consideration for Twitter: referral links shared publicly are visible to anyone. This means your referral link could be shared beyond the original referrer's network. Decide in advance whether you want to allow public referral links (which can drive more volume) or restrict reward attribution to direct installs only (which is more controlled).<\/p>\n\n\n\n Facebook uses Open Graph meta tags for link previews, and the preview is shown both in the News Feed and in Messenger. The Facebook does not allow scraping of pages that require authentication, so your referral link landing page needs to be publicly accessible without login. The OG tags need to be rendered server-side (not by JavaScript) because Facebook's scraper does not execute JavaScript.<\/p>\n\n\n\n One frequently missed detail: Facebook caches OG previews aggressively. If you update the og:image or og:description for a URL, the old preview may persist for days. You can force a cache refresh using the Facebook Sharing Debugger<\/a>.<\/p>\n\n\n\n For Messenger sharing specifically, you can use Facebook's Send Dialog<\/a> to open a pre-composed message, though this requires your app to be registered as a Facebook app.<\/p>\n\n\n\n SMS is consistently one of the highest-converting referral channels for mobile apps, particularly in markets where messaging apps have not displaced native SMS. The reason is simple: an SMS from a known contact carries more trust than any other channel.<\/p>\n\n\n\n SMS link previews are handled differently on iOS and Android:<\/p>\n\n\n\n iOS (iMessage):<\/strong> iMessage renders a rich link preview for URLs using the Android:<\/strong> Most Android messaging apps render basic link previews, but behavior varies significantly by carrier, device, and app. Google Messages renders rich previews on RCS threads but not on standard SMS.<\/p>\n\n\n\n For SMS sharing, keep the message text short. The referral link itself takes up space, and long pre-populated messages feel unnatural. Something like "I've been using [App Name] and thought you'd like it: [link]" is more likely to actually get sent than a marketing paragraph.<\/p>\n\n\n\n To trigger an SMS share from your app on iOS, use the Email sharing is lower volume than social or SMS for most apps, but the users who share by email tend to be more deliberate, which means the people they share with are often genuinely interested.<\/p>\n\n\n\n For email sharing from a mobile app, the native approach is to use Email link previews are rendered by the receiving mail client. Gmail and Apple Mail both render the page title and a brief snippet. Unlike social platforms, email clients generally do not render og:image in the preview (though the link will still work correctly).<\/p>\n\n\n\n For the email body template, include:<\/p>\n\n\n\n Keep the pre-populated email short enough that it does not look like a marketing blast. The user needs to feel comfortable sending it to a friend without feeling like they are forwarding a spam campaign.<\/p>\n\n\n\n Across all platforms, the link preview experience depends on your Open Graph implementation. Here is what to check:<\/p>\n\n\n\n og:title:<\/strong> Keep it under 70 characters. Shorter is better. "Get $10 off your first order at [App Name]" is more specific and more clickable than "My referral link."<\/p>\n\n\n\n og:description:<\/strong> 2-3 sentences maximum. Describe what the app does and what the new user gets. This is often skipped over, but platforms like WhatsApp and iMessage render it prominently.<\/p>\n\n\n\n og:image:<\/strong> Serve images at 1200×630 pixels. Use a CDN so they load fast. The image should be compelling on its own, because on many platforms the image gets more visual attention than the title or description.<\/p>\n\n\n\n og:url:<\/strong> Set this to the canonical URL of your referral landing page, not the tracking redirect URL. This helps platforms cache the preview correctly.<\/p>\n\n\n\n For referral links that go through a redirect for tracking, the redirect endpoint itself should return the appropriate OG tags (or redirect with a Tolinku's referral links support custom OG metadata per link, so you can set a referral-specific title and image without changing your main app's OG configuration. See the referral links documentation<\/a> for setup details.<\/p>\n\n\n\n Before launching a referral program, test your links on every platform you expect users to share on. The Facebook Sharing Debugger<\/a> and Twitter Card Validator<\/a> let you preview how your links will appear. For WhatsApp, there is no official preview tool, so manual testing on a real device is the most reliable method.<\/p>\n\n\n\n Test the full referral flow on both iOS and Android: tap the share button, share to each target platform, click the shared link from a fresh device, and confirm the attribution is captured correctly. Issues that only appear in real cross-device testing are much harder to find after launch.<\/p>\n\n\n\n For more on how referral attribution works through deep links and across installs, see the referral attribution guide<\/a> or the Tolinku referrals overview<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Where and how users share your referral links shapes how many people click them.
