Finding the right balance: what’s the ideal length for social videos?

Shorter attention spans vs algorithm updates: is there really an optimal video length?

In 2019, Facebook announced a set of changes to the way they rank videos. Encouraging video creators to keep their audience engaged for at least one minute, they added that:

“videos get shown organically to more people when they’re at least 3 minutes long”

So it’s true that longer videos have a better chance of organically appearing on feeds.

Since then, however, many people have taken the longer-format rule and ran with it. Marketers are eking short and snappy material into extravagantly-long videos – at the expense of genuine engagement.

Creating lengthier videos won’t automatically guarantee you the top-spot on timelines. On the contrary, content that’s dragged out for longer than necessary could be hurting your chances of reaching a higher audience.

Spark a conversation

Facebook aren’t just looking at the length of your video and ranking it accordingly. To make sure your content is good quality, they’re also looking at how engaged your viewers are.

As part of their News Feed ranking update, Facebook are more likely to favour videos that spark interaction and conversation. So while your three-minute video is perfectly timed for Facebook, that alone won’t help you rank organically. You’ll need to give your audience something to talk about.

What does engagement involve? Along with people who ‘like’ or comment on your post, Facebook also track those who watch your content for longer than a minute. So whether your video is two minutes or ten, you’ll need to create content that gets your audience talking (and watching).

Top tip: gear your video content around your audience’s specific interests and habits to capture their attention.

Loyalty is key


Along with video length and engagement, it also pays to make sure your audience returns. If your viewers keep coming back for more, Facebook will prioritise your video content.

As they summarised in their best practices:

“We take into account how frequently viewers return to watch your content and how many you retain on a weekly basis.”

Instead of creating one mammoth video tutorial, you could see higher engagement by breaking your content down into shorter videos and posting them as a series. If you create regular content, your audience is more likely to return – which could help your videos appear on more feeds.

Handy hint: stick to a weekly or daily schedule to encourage your audience to come back for more.

Finding the balance

Algorithm updates mean videos under two minutes are less likely to appear organically. And yet a study from Hubspot found that video engagement peaks at just one minute on Facebook.

In an age of time-poor consumers and shortened attention spans, longer videos can be off-putting. That’s why, no matter how long your video lasts, it’s essential to grab your audience’s attention from the very beginning.

A Boost with Facebook event in Brooklyn revealed that 47% of value in a video is delivered in the first 3 seconds.

By conveying your core message straight away, you’re more likely to keep your audience on board. Unnecessary preamble and build-up can frustrate your audience, especially if they’re short on time. You could risk pushing them away and cause your engagement stats to plummet.

Ultimately, shorter is best. Despite the algorithm updates, overly long videos could bore your audience and negatively impact your engagement. As long as you cover your essential points and keep your videos above the two-minute mark, your videos should appear in the right places.

So, what is the right video length?

Your video should last long enough to get your main message across – and not one second longer. If you can keep your video around 3 minutes long, you could keep your audience engaged without being hidden by algorithms. If your content is longer (like a video tutorial), it could be worth breaking it down into smaller videos.

Before you settle on your video duration, see if your audience prefers shorter or longer videos. Find your viewers typical drop-off point by looking at your Facebook engagement stats.
