How to link TikTok to Instagram (and grow both)
TL;DR: You can link TikTok to Instagram in under two minutes by connecting accounts inside TikTok's settings. The bigger win is adding a single link-in-bio page to both profiles so followers from either platform land in one place you actually control.
How to link TikTok to Instagram: the quick answer
Go to your TikTok profile, tap Edit profile, find the Instagram field, and connect your account. That's it. Instagram shows up as a tappable icon on your TikTok profile, and TikTok's watermark appears on any video you share to Instagram Reels. The whole process takes about 90 seconds.
But that built-in connection only solves half the problem. It pushes followers toward your Instagram handle. It doesn't give you anywhere to send them once they arrive, and it doesn't work the other direction nearly as well. The rest of this article covers how to make cross-promotion actually move the needle.
Why linking your accounts matters for growth
TikTok has over 1 billion monthly active users. Instagram has roughly 2 billion. The audiences overlap, but not completely. A follower who found you on TikTok may have never seen your Instagram content, and vice versa. Every creator who treats those as separate audiences is leaving reach on the table.
Cross-promotion across platforms compounds your follower growth faster than grinding one platform in isolation. According to Sprout Social's 2024 content benchmarks, creators who actively cross-link their social profiles see 30 to 40 percent faster follower growth on secondary platforms compared to those who don't. That's not from posting twice as much content. It's from making it easy for people who already like your work to find more of it.
There's also a practical time-saving angle. A TikTok video you already filmed and edited can become an Instagram Reel with minimal extra effort. Cross-posting the same clip (or a slightly trimmed version) means you're not producing separate content calendars for each platform. You're multiplying the reach of work you've already done.
Step-by-step: how to link TikTok to Instagram
The native connection between TikTok and Instagram runs through TikTok's profile settings. Here's how to set it up on both iOS and Android.
- Open TikTok and tap the Profile icon in the bottom-right corner.
- Tap Edit profile.
- Scroll to the Social section and tap Add Instagram.
- TikTok will open an in-app browser and prompt you to log in to Instagram or confirm your existing login.
- Approve the connection. Your Instagram handle now appears as a tappable link on your TikTok profile.
To go the other direction and add a TikTok link to Instagram, the process is manual rather than a two-way API sync. Open Instagram, go to Edit profile, and paste your TikTok profile URL into the website field or the Links section (available on Instagram for some accounts). That URL is clickable from your Instagram bio.
One thing to watch: Instagram's bio only shows one URL prominently. If your TikTok link is sitting there, your Etsy shop, latest YouTube video, and everything else isn't. That's where a link-in-bio page solves the problem the native integration doesn't.

The real bottleneck: one link, multiple destinations
Both TikTok and Instagram give you one bio link. One. That's a significant constraint when you want to send followers to your new video, your newsletter, your merch store, and your other social accounts all at once.
The standard workaround is a link-in-bio page: a single URL that acts as a mini homepage with all your important links on it. You put that one URL in both your TikTok bio and your Instagram bio. Any follower from either platform lands in the same place.
Most creators know about this approach. Fewer think carefully about which tool they use to build it, and that choice has real consequences for discoverability and long-term growth.
Linktree is the most recognizable name in this category, but it has three specific problems. First, Linktree-hosted profiles live at linktr.ee/yourname, which means the SEO value of any link clicks accrues to Linktree's domain, not yours. Second, the free tier forces Linktree branding onto your page. Third, the analytics on free accounts are stripped back to the point where you can't tell which specific links are driving clicks.
MyLinks.page solves all three. You can connect a custom domain (yourname.com or yourlinks.com) so you're building authority on a URL you own. There's no forced branding on the free tier. And the analytics show you which links are getting clicked, when, and from which platform, so you can actually learn what's working across your TikTok and Instagram audiences.
How to set up your link-in-bio page for both platforms
A link-in-bio page that serves both TikTok and Instagram followers doesn't need to be complex. It needs to be fast to load, clearly laid out, and include the right links for where that audience wants to go next.
Start with your most important destination at the top. For most creators, that's the newest piece of content or a primary product. Then add your other social platforms, your newsletter, your shop, and any pinned links that are always relevant. Keep the page to six to eight links maximum. More than that and you're asking followers to scroll and make decisions, which kills conversion.
On the technical side, add your link-in-bio URL to both platforms in the same session so you don't forget the second one. On TikTok, go to Edit profile and paste it into the Website field. On Instagram, do the same in the Links section of your bio. Now the native Instagram icon on your TikTok profile and the URL in your Instagram bio both send people to the same page.
One small but effective move: use UTM parameters on your links so your analytics tool can distinguish clicks coming from TikTok versus Instagram. A URL like mylinks.page/yourname?utm_source=tiktok versus ?utm_source=instagram tells you exactly which platform is driving traffic to each destination. MyLinks.page supports UTM tracking natively, so you see this breakdown without needing to build it manually in Google Analytics.

Cross-promotion tactics that actually build following
The technical setup above takes ten minutes. The part that compounds over time is your actual cross-promotion habit. A few approaches work better than others.
Repurposing content is faster than creating separate content for each platform. A TikTok video exports cleanly as an Instagram Reel if you keep the aspect ratio at 9:16. The one adjustment worth making is removing or covering the TikTok watermark before posting to Instagram, since Instagram's algorithm reportedly reduces the reach of videos it detects as repurposed from TikTok. Apps like CapCut or Canva let you recompose the clip without the watermark in a few minutes.
Tease platform-exclusive content. If you post detailed tutorials on Instagram and shorter entertaining clips on TikTok, mention it on each platform. "The full breakdown is on my Instagram" on a TikTok video gives followers a specific reason to go follow you on Instagram too, not just a vague invitation to check you out there.
Update your link-in-bio page when you post something new. If you just published a new TikTok, move that link to the top of your page temporarily. Followers who arrive from Instagram will see what you're currently promoting on TikTok and may follow you there. The reverse works just as well. The link-in-bio page is a live document, not a set-it-and-forget-it URL.
Common mistakes when linking TikTok and Instagram
The most common mistake is not doing it at all. Plenty of creators with strong followings on one platform have a completely dormant account on the other because they never built the bridge. The native TikTok-to-Instagram connection takes 90 seconds and has no downside.
The second mistake is pointing both bio links at different destinations. One creator might have their TikTok bio pointing at their Etsy shop and their Instagram bio pointing at their YouTube channel. That's two separate conversion paths you can't measure together, and it makes your overall presence feel fragmented. A single link-in-bio page that aggregates everything is almost always the better answer.
Third: ignoring the analytics. If you've set up UTM tracking and you're getting ten times more clicks from TikTok than Instagram, that's information. It tells you which platform your audience is more engaged on, and it might change how much effort you put into each one. Most creators set up their link-in-bio page and never look at the numbers again. The ones who do look tend to grow faster because they're responding to real behavior instead of gut feel.
The bottom line on linking TikTok and Instagram
Connecting your TikTok to Instagram through the native settings takes two minutes and is worth doing immediately. The bigger opportunity is building a single link-in-bio page that both profiles point to, so you're not splitting your audience across multiple disconnected destinations.
A free MyLinks.page account gives you a clean, unbranded page with analytics and custom domain support. You can import any existing link-in-bio page in about 60 seconds. Set up the native TikTok-Instagram connection, put your MyLinks.page URL in both bios, and your cross-platform setup is done.
