— TABLE OF CONTENTS

As a Product & UX designer and YouTuber myself, I always have one thing to say about YouTube. The truth is that on that platform, nothing is accidental or coincidental. On Youtube, everything is carefully designed and expertly deliberate. 

YouTube tailors all its recommendations and suggestions to suit a user’s specific interests. This is a combination of high click-through-rate thumbnails and videos that maintain end-to-end engagements. YouTube’s ultimate goal is to keep users on platform for aslong as possible. The more videos watched, the more ad revenue they make. In 2021 alone, YoUTube generated $7 billion in ad revenue.

So, how does YouTube keep users on the site? What UX tactics has YouTube used to maximize watch time? 

These are my favourites:

How YouTube Tracks Your Every Move

Youtube, and Google for that matter, have a powerful system that works around the clock to build a digital profile of you. The digital profile is what helps their AI to understand who you are, what your preferences are, and more importantly, what you might like to see next.  

When you watch a video, every single like, comment, watch time, and drop-off is tracked in the system to help build your profile. 

As a YouTuber myself, I can see exactly where the biggest drop off is per video. These kinds of metrics help me to understand what kind of content is engaging, and what I need to drop. 

For example, one of my UI training videos had a long introduction leading to a drop-off point early on in the video. By changing the way I create content, I was able to retain viewers for longer, and ultimately help Youtube retain users. 

Remember that YouTube has carefully designed everything to hook users in. The better the content, the longer the binge-session, and the happier YouTube is.

More engagement = More ads = More revenue.

Dynamic and Intuitive Personalisation on the Home Page 

YouTube is a master of giving you a personalised, tailored experience. The YouTube algorithm is incredible when you think about it. Mysterious, complex, and enigmatic, it is capable of predicting (with great accuracy) what you want to watch, what you need to watch, and how to keep you hooked.

When someone first lands on YouTube’s homepage, the selection of videos is a little broad. This is because the algorithm is waiting for the user to give the first signal of what they want to see. The selected videos for the homepage are chosen based on two kinds of “ranking signals”:

  • A/B Testing: Based on likes, dislikes, click-through rates, average view duration and percentage viewed, and even viewer surveys. When someone uploads a video, the algorithm pushes it to the homepage of a few users. If they engage with it enough, it gets pushed more and more.
  • Personalisation: This is what captures my UX attention: YouTube has mastered personalisation, meaning that they present videos to people that they believe are relevant based on their past behaviour. If someone watched a lot of cooking channels last week, they’ll be pushed to watch even more cooking channels. As their interests shift and change, so does the algorithm to keep up. 

YouTube Predicts Preferences Based on What You Don’t Watch

YouTube also takes into account the videos you decide not to click on. It helps to narrow down your choices and gives the algorithm more to work with. Their AI can understand you better than you understand yourself. 

For example, if you’re browsing cooking videos, you might ignore a 15-minute fresh pasta cooking guide by Nigella Lawson. Instead, you go with the quick Jamie Oliver 2 minute version. 

YouTube’s AI now knows that you aren’t looking for a long cooking lesson, only short bites. It may also test your preference in YouTube presenter. Now your homepage will be filled with Jamie Oliver clips and Jamie Oliver related content. 

Notifications Give Direct Access To User’s Attention

YouTube Notifications

If you have the YouTube app on your device, you’ve probably had a notification flash across your screen.

New uploads, channel updates, even trending videos – YouTube has strategically created ping notifications that give them direct access to user’s attention. 

Experts revealed in the 2021 Conference on Human Factors in Computing Systems that notifications were specifically targeted and designed to increase usage time.  

The report stated that “The ‘Notifications digest’ lets a user bundle push notifications together into a single notification each day, which may reduce the triggers that lead to non-conscious, habitual use.”

While many users simply disable notifications on their devices, those who don’t have an increased chance of interacting with YouTube frequently and habitually. 

Influencer-Driven Content Draws Users Back To The Platform

Ask a few people what the appeal of YouTube is, and they’ll say that they appreciate user-generated content. That is, content that’s created by creators, and not content produced for big-budget streaming platforms like Netflix or Hulu. 

A marketing study found that brand collaborations with YouTube creators are “4x more effective at driving lift in brand familiarity than those with celebrities.”

Many believe that this shift in dynamics is due to how YouTube creators are perceived when compared to other platform influencers. YouTube seems to continue to foster authenticity and honesty, creating higher engagement and strong audience retention. 

Auto-Play and the “Lean-Back” Hook

The auto-play feature enables what Youtube describes as a ‘lean back’ experience for the user. Relevant videos continue playing without you even needing to reach for your mouse. 

Taking everything into account that YouTube knows about you, (which, I hate to say, is a lot more than you think), autoplay helps to keep you on the site longer by literally continuing to play content for you. 

This kind of system is a God-send for those looking to use YouTube as a background music playlist or a binge-watching session. It also helps to take the guessing work out of deciding what to watch next. 

For example, a user is building their own PC and watching a product review by a well-known industry expert. Based on their Google search, YouTube knows the user is searching cooling systems. So, the next video to pop up on auto-play is by the same industry expert reviewing cooling systems? 

Coincidence? There are no coincidences with YouTube. 

When You Subscribe To A Channel, YouTube Prioritises Relevant Content

The sentence: “Thanks for watching guys, and remember to like, comment, and subscribe to my channel!” seems to have become a given in the YouTube universe. 

So, why does YouTube like you to subscribe to channels? It’s because it’s an opportunity to keep you watching longer. 

Once you subscribe to someone, they will bombard you with all their videos to keep you on the platform. This means videos from years ago, old videos, even videos the creator probably forgot they uploaded. If you show interest, YouTube will do everything to keep you there. 

Engagement Loops Pique Your Interest

This is a favourite tactic of mine, purely because it’s so simple you don’t even realise it’s happening. 

YouTube has been designed to surround you with content at all times. Videos in the sidebar, suggestions on what to watch, links, promotions – it’s an engagement loop designed to keep you hooked on the site. 

The Power of YouTube

Once again, I am just staggered by the numbers. Not only has YouTube become a titan entertainment/education/search engine platform, but it’s also managed to convince more than 50M users to pay for a free service.

What YouTube has achieved is nothing short of phenomenal. 

From the lens of a YouTube Creator and heavy user of YouTube, I only hope that the platform continues to grow to give me the opportunity to connect with and educate a wider audience. 

From a product UX case study designer lens, I think they still have a lot of room to grow into. I am sure churn and activation rates are key metrics the product team is focusing on.
