Choose auto-share when you are happy for Instagram's performance signals to decide which trials reach your followers. Choose manual when you want to review the numbers first or control when and where the reel lands in your feed.
That is the whole decision, but it is easy to get wrong. Share a weak trial and it can land flat with the people who already like you. Never share a strong one and your followers miss your best work. This guide walks through what each mode does, what Instagram says about it, and how to choose. If you are new to trials, start with our guide to scheduling trial reels.
What Does Auto-Share Actually Do?
When you turn on Instagram's "Share to everyone automatically" setting, a trial "will automatically be shared if it's performing well soon after you publish it, based on signals like views and engagement" (Instagram Help: About trial reels). Instagram's Reels page adds that this happens if a trial is "getting a lot of views within the first 72 hours" (Instagram's Reels page).
One detail catches people out. In the Instagram app, that setting "will be automatically applied to all trial reels you share in the future unless you change it." Turn it on once and it sticks.
Under the hood, Meta's publishing API offers the same two paths for scheduling tools: a manual graduation strategy, where you graduate the trial in the Instagram app, and a performance-based one, where the trial is "automatically graduated if the trial reel performs well" (Meta developer docs).
Why it works: Auto-share removes a task. If you post a lot of trials, you don't have to check each one and decide.
What Counts as "Performing Well"?
Instagram says it looks at "signals like views and engagement" in the first 72 hours. It hasn't shared a specific number, so focus on what you can control: a strong hook and a reel people want to finish.
That shapes your decision. With auto-share, Instagram's signals decide. With manual, you set your own bar, such as "share only if watch time beats my last three trials."
Why it works: Choosing who applies the standard, Instagram or you, is the real decision between the two modes.
Why Choose Manual Sharing?
1. You want to read the numbers first. Instagram says trial insights arrive within 24 hours. Manual gives you time to compare a trial with your other trials before anyone you know sees it.
2. You care where it lands on your grid. Once shared, Instagram says a trial is displayed on the main grid and Reels tab of your profile. Manual lets you share it when it fits your grid plan.
3. You want to control timing. Maybe a trial about a sale should reach followers the morning the sale opens, not whenever Instagram decides.
4. You are testing several versions of one idea. If you post three cuts of the same reel, auto-share could promote more than one. Manual lets you pick a single winner.
Why it works: Manual sharing keeps your followers' experience in your hands. You only show them what passed your test.
When Is Auto-Share the Better Call?
-
You post trials regularly and don't have time to review each one.
-
Grid placement doesn't matter much for this reel.
-
You trust performance signals more than your own gut on what your audience wants.
-
The reel is timeless, so it doesn't matter exactly when it reaches followers.
Why it works: Auto-share is strongest when speed matters more than control. It quietly promotes what is already working while you focus on the next batch.
Can You Share a Trial Later?
Yes, if you chose manual. You share it from the Instagram app when you're ready. That is exactly what Planoly's Manual option means: you share it with your followers from Instagram when you're ready.
Share the trials that earned it. A trial that didn't connect with non-followers is better treated as a lesson than pushed to your followers just because it exists.
Why it works: Treating "share later" as a decision, not a default, keeps your followers-first feed full of proven content.
What If a Trial Never Gets Shared?
That is normal. Most tests should lose. A trial that never reaches followers still taught you something about a hook, an audio choice or a format. Write down what you learned and use it in your next followers-first post.
A trial that wasn't shared also doesn't drag down your regular content. Instagram says trial reels "are evaluated independently in Instagram's ranking and don't impact the performance or ranking of your standard reels content" (Instagram Help).
Why it works: Expecting most trials to stay trials removes the pressure. You are buying information, not guaranteed reach.
How Do You Choose Auto or Manual in Planoly?
Planoly's Trial reel tool offers the same choice Instagram does. Upload one video to an Instagram channel, set the posting method to Auto-post, open the Trial reel tool in the toolbar under the caption, and pick:
-
Off: a normal reel, no trial.
-
Manual: you share it with your followers from Instagram when you're ready.
-
Auto: if it does well in its first 72 hours, Instagram shares it with your followers.
Then schedule the post as usual. The full steps are in our trial reels help article.
Frequently Asked Questions
How long does Instagram take to auto-share a trial reel?
Instagram says auto-sharing happens if a trial is getting a lot of views within the first 72 hours. It doesn't give an exact time or threshold.
Does the auto-share setting apply to all my trials?
In the Instagram app, yes. Instagram says the setting applies to all future trial reels unless you change it. In Planoly, you choose Off, Manual or Auto on each post.
Will my followers see a trial reel if I choose manual?
Not in Feed or Reels until you share it. Instagram notes some people may still find it through DMs, audio pages or search engines.
Does an unshared trial affect my other reels?
Instagram says trials are ranked independently and don't affect your standard reels.
TL;DR
-
Auto-share: Instagram shares trials that perform well in the first 72 hours, based on signals like views and engagement.
-
Manual: you review the numbers and share when it fits your grid and timing.
-
Mix both. Manual for grid-worthy or dated reels, Auto for evergreen tests.
