How to Collab on Instagram Reels

Doing a collaboration on an Instagram Reel is one of the single most powerful ways to get your content in front of a new, targeted audience. This guide explains exactly what the feature is, why it's so effective for growth, and provides step-by-step instructions for setting up your first successful collaboration.

What is an Instagram Reel Collaboration?

You’ve probably seen them in your feed - a single Reel that appears to be posted by two different accounts at the same time. That's the power of Instagram’s Collab feature. It allows one user to invite another to be listed as a co-author on a single Reel or feed post.

When the collaborator accepts, the Reel appears on both of your profiles. Here’s what makes this different from just tagging another account:

• Shared authorship: Both of your usernames are displayed at the top of the post.
• Shared audience: The post is served to a portion of each creator's followers.
• Combined analytics: All the likes, comments, and views are consolidated and displayed on the same post, visible on both profiles.

Think of it as co-hosting a party instead of just mentioning that a friend is there. You’re sharing the stage, the audience, and the credit. This amplifies its reach far beyond what either account could achieve alone.

Why You Should Absolutely Bother with Reel Collabs (The Big Benefits)

If you're serious about growing your brand organically on social media, collaboration posts aren't a novelty, they're a core part of a smart strategy. The return on investment in a well-planned collab is massive.

1. Explosive Reach and Audience Growth

The number one benefit is getting your content, and your profile, in front of a completely new but relevant group of people. When you collaborate with another creator, you’re not just gaining access to their followers - you’re gaining a trusted introduction. Suddenly, people who have never heard of you see your content "co-signed" by an account they already follow and trust.

Example: A handcrafted pottery shop collaborates with a popular interior design influencer. The Reel, featuring the potter’s vases in the influencer's beautifully styled home, gets pushed to thousands of design enthusiasts. This curated audience is far more likely to convert into followers and customers than a random audience from a viral trend.

2. Supercharged Engagement

Instagram's algorithm pays close attention to how quickly a post gets engagement after it goes live. Collab posts have a built-in advantage. By merging two communities, you instantly double the potential starting pool for immediate likes, comments, shares, and saves. This early burst of activity signals to the algorithm that the content is valuable, prompting it to push the Reel to an even wider audience on the Explore page and Reels tab.

3. Instant Credibility and Social Proof

Partnering with a respected creator in your niche acts as an instant credibility booster. It tells new audiences, “This account is worth following because someone you trust also trusts them.” This principle, known as social proof, is incredibly persuasive. It shortens the time it takes for a new viewer to decide to hit the “Follow” button because the decision has been endorsed by a trusted source.

4. Fresh, Inspiring Content

Hitting a creative wall is real. Collaborations are a fantastic way to break out of your content comfort zone. By merging your style and expertise with someone else's, you can create something fun, original, and far more dynamic than what you might have made solo. This cross-pollination of ideas keeps your content fresh for your existing audience while also impressing a new one.

How to Add a Collaborator on Instagram Reels: A Step-by-Step Guide

The technical part of setting up a collab is simple. All the real work comes in the planning and relationship-building beforehand, but once your content is ready, inviting a co-author takes seconds.

Heads up: You can only invite collaborators from public accounts, and you can only add one collaborator per post. If you've got a killer idea for three or more people, consider making it a series of collabs instead.

Step 1: Create Your Reel

Film and edit your Reel just as you normally would. Add your music, text overlays, filters, and any other effects. Once you're happy with your creation, tap "Next" to continue to the final sharing screen.

Step 2: Access the Account Tagging Menu

On the share screen (where you write your caption), tap on the option that says “Tag people.” This is the same menu you would use to tag a friend in a photo.

Step 3: Invite Your Collaborator

At the top of this next screen, you’ll see two options: “Add tag” and “Invite collaborator.” Tap “Invite collaborator.”

Step 4: Search for and Select Your Collaborator

A search bar will appear. Start typing the username of the account you want to collaborate with. Tap their name when it appears in the list. Their account will now be listed under the "Collaborators" section.

Step 5: Publish Your Reel

Finish writing your caption, add hashtags, and a location if you like, and then hit the “Share” button. The Reel will now be live on your profile.

Step 6: Your Collaborator Must Accept the Invitation

This part is critical. The collab isn’t complete until the other person accepts. Your collaborator will receive a notification and a direct message with an invitation. The prompt will allow them to "Accept" or "Decline" the collaboration. Once they tap "Accept," the Reel will immediately appear on their profile grid, their username will be added to the header, and the post will start being shown to their followers.

Best Practices for a Winning Collaboration

A successful collab is 90% strategy and 10% tapping the right buttons. Follow these best practices to make sure your partnerships are powerful, not pointless.

1. How to Choose the Right Collab Partner

Who you partner with matters more than anything else. A poorly chosen partner won't just result in a low-performing Reel, it could actively damage your brand's reputation.

• Audience Alignment is Everything: Don't get fixated on follower counts. Ask yourself: "Who is their audience, and would that audience genuinely care about what I do?" A creator with 10k highly engaged followers in your niche is far more valuable than one with 100k followers who have no interest in what you offer.
• Shared Values and Vibe: Look for creators whose content style, tone, and overall brand values complement yours. You want the partnership to feel authentic and natural to both audiences. If you're a wholesome baking blogger, partnering with an edgy political comedian probably won’t feel right.
• Review Past Performance: Look at their previous posts. Do their Reels get good engagement? What do the comments look like? Make sure they have an active and positive community.

2. Planning Is a Non-Negotiable

Don't just hit someone up and say "Wanna make a Reel?" Professionals come with a plan and a clear idea of the mutual benefit.

• Define a Clear Goal: What, specifically, do you want this Reel to accomplish? Do you want to drive traffic to a product, increase your email signups, send followers to your podcast, or simply gain brand awareness? The content of your Reel should directly support that goal.
• Brainstorm Ideas Together: A true collaboration involves both creators' input. Come to the table with a few initial ideas, but be open to brainstorming a concept that incorporates both of your strengths and appeals authentically to both of your audiences.
• Sort Out the Logistics: Who is responsible for what? Be crystal clear from the start. Create a simple outline that covers everything:
  • Concept: What's the main idea/storyline?
  • Filming: Who films what parts? Who provides what equipment?
  • Editing: Who is cutting together the final video?
  • Copy: Who is writing the caption and hashtag research?
  • Deadlines: When does everything need to be completed?

3. Writing the Perfect Pitch DM

The way you propose a collab matters. Don't just slide into their DMs with a low-effort "let's collab." Show you're a professional who respects their time and brand.

• Personalize It: Start by mentioning something specific you like about their work. Reference a recent Reel or Story you enjoyed. Show that you are an actual fan, not just a spam bot.
• Focus on Mutual Value: Instead of “this would be good for me,” frame it around "what's in it for both of us." Phrase it as something like: “I had a fun concept for a Reel that I think our audiences would absolutely love. I loved your post about [...] and I think our brands would be a perfect fit.”
• Start Small: Don't reach out to a creator with a million followers for the first time asking for a massive project. Ask for a fun Reel instead. Build the relationship, which will open the door to bigger projects later.
• Be Clear and Concise: Come to the conversation with one or two clear concepts, not just a vague idea to "work together." Make it as easy as possible for them to say “yes.”
