The YouTube algorithm: how it works and tips to optimize in 2025

If you’re serious about YouTube marketing, understanding how the algorithm works is key to getting your content discovered on the platform.

Ever wonder how YouTube knows exactly what you want to watch?

Behind the scenes, one of the world’s most powerful recommendation engines is analyzing thousands of signals about you – and each of it’s 2.53 billion monthly active users.

In this post, we’ll break down how the YouTube algorithm works in 2025 and how you can use it to your advantage.

What is the YouTube algorithm?

YouTube’s algorithm is a system that recommends videos to users based on what they watch, how they interact with content and even when they’re most active.

It looks at thousands of different factors to serve up content each user is most likely to enjoy. The algorithm’s goal is simple: keep viewers glued to the platform and watching more.

YouTube algorithm changes to know about in 2025

YouTube keeps fine-tuning its algorithm to make recommendations smarter, faster and more relevant. Here’s what’s changed and how it could impact your visibility this year.

1. Hyper-personalization with AI

Thanks to AI, YouTube can now recognize patterns and tailor suggestions based on individual user habits. For example, if someone watches short clips on their phone on their lunch break and longer videos on TV before going to bed, their feed adjusts to match that behavior.

“The recommendation system uses time of day and device as some of the signals… we try to identify if you tend to have a preference for watching news in the morning and comedy at night.” Todd Beaupré / Senior Director of Growth & Discovery, YouTube

What this means for marketers:

Visibility now depends on how well your content fits each viewer’s personal patterns, not just how well it ranks. So focus on content that mirrors your audience’s habits.

2. Content quality trumps channel size

In 2025, small channels have a real shot at wide reach. The algorithm cares more about viewer response than subscriber counts or upload history. If a video hooks the right audience, it can get recommended, no matter who made it.

What this means for marketers:

Don’t wait until you have a full content library to get serious. One strong, well-targeted video can put your brand on the radar, even if you’re new to the platform.

3. Your old videos can get new life

YouTube’s algorithm’s gotten better at recognizing when older videos are suddenly relevant. If a topic starts trending, like gift ideas in December or a viral skincare routine, YouTube will surface related content, even if it was uploaded years ago.

What this means for marketers:

Create more evergreen content. Revisit older videos and update thumbnails, tweak titles and optimize descriptions with timely keywords to help them get picked up when interest spikes.

How the YouTube algorithm works

The YouTube algorithm is a group of systems working together to figure out what each person is most likely to watch and enjoy.

Instead of pushing your content out, it pulls in the right videos for each individual viewer, based on what it thinks they want at that moment.

Complex? Yes. But the algorithm’s complexity is intentional. It’s designed to match the complexity of human viewing preferences and behaviors.

Here’s what marketers need to know about how it works.

Where your videos get recommended

Home

This is the personalized feed viewers see when they open YouTube.

It’s shaped by their watch history, what similar users engage with, and when and how they’re browsing, like time of day or device.

Search

Two users can type the same query and see different videos based on their viewing habits.

That means showing up in search also depends on how well your content aligns with a person’s interests, not just keywords.

Suggested videos

This is the sidebar content YouTube recommends while someone is watching.

The algorithm tries to keep the session going by surfacing what it thinks that specific viewer wants to see next.

Factors that influence the algorithm

YouTube’s algorithm is more context-aware and viewer-first than ever before. Here’s what actually shapes your rankings:

Engagement and watch behavior

Watch time still matters. So do likes, clicks and comments. But their importance depends on the format and viewing context.

For example, long-form videos watched on a smart TV are often measured by how long someone sticks around. But for a short unboxing clip on mobile, YouTube might prioritize how many people click, share or rewatch.

Individual context

YouTube dives deep to personalize recommendations for each individual user. It looks at what you watch, but also when, how and on which device you’re watching.

This means your content is more likely to surface if it fits naturally into someone’s daily viewing patterns, not just if it ranks well overall.

Viewer satisfaction

YouTube doesn’t just care if someone watches your video. It wants to know if they liked the experience. The platform collects feedback through millions of user surveys, asking questions like “Was this video helpful?” or “Did you enjoy watching this?”

That data goes straight into the algorithm. If your video leaves people feeling satisfied, it’s more likely to rank. If not, it might quietly get deprioritized, even if they watched till the end.

Content relevance and nuance

YouTube’s AI has gotten much better at understanding what a video actually is. It can now pick up on tone, format, structure and even the creator’s delivery style.

A “how-to” video might be recognized as expert-led or beginner-friendly. That level of nuance means you should think beyond basic keywords and focus on the details.

Moreover, if your content is evergreen, it can resurface months or even years later when that topic becomes relevant again. For example, an older holiday gift guide might suddenly trend again in December if people start searching for that kind of content.

Multi-language signals

If you’re publishing videos with multiple audio tracks or dubbing for different regions, YouTube treats each language version as its own performance track.

That means your Spanish dub might take off in Latin America, even if the original English version doesn’t. This opens up global growth opportunities for international brands.

How the YouTube Shorts algorithm works

The algorithm for YouTube Shorts works differently from long-form.

It all comes down to intent. With long-form videos, viewers choose what to watch. With Shorts, they’re swiping through a feed and discovering new content.

The Shorts algorithm may also test your content with a small audience first, then either expand reach based on performance or taper it off.

What matters to the YouTube Shorts algorithm

• The viewed-vs-swiped-away ratio
• A strong opening few seconds
• Story completion within the time limit
• Seed audience engagement

What doesn’t matter as much

• Thumbnails (most aren’t seen)
• Posting time or day
• Upload frequency
• Minor changes or reposts

Bottom line: Shorts live or die by how well they hold attention in the first 1–3 seconds. Focus on delivering quick, engaging content that stops the scroll.

15 YouTube algorithm strategies and tips for brand growth

Knowing the ins and outs of the algorithm is great, but how do you put it to practice? Perfect your execution by keeping the following best practices in mind. We’ll cover both strategic and technical tips to get your brand to the top as efficiently as possible.

1. Focus on viewer satisfaction

YouTube cares about how your audience feels after watching. If they’re happy with the content, they’re more likely to stick around and return to your channel.

Here are some tips to increase satisfaction:

• Deliver what the title and thumbnail promise
• Get to the point quickly and keep the pacing tight
• Make sure the content actually solves a problem or tells a story

When viewers feel like your video was worth their time, the algorithm notices.

This Betty Crocker video is a prime example of how to frame a simple recipe around a specific problem and then present the solution as quickly, clearly and naturally as possible.

2. Stick to schedule that works

You don’t have to upload daily to grow on YouTube. What matters more is showing up consistently and publishing when your audience is actually around to watch.

Check your Analytics to find out the best times to post for you, and share your content right before those peak hours. A weekly or biweekly cadence is plenty, as long as you stick to it.

That reliability builds trust with your viewers and gives the algorithm stronger signals to work with.

3. Use Shorts for discovery

YouTube Shorts are a great way to reach people who’ve never heard of your brand. They show up in a separate feed and the swipeable format is perfect for quick discovery.

Here are some YouTube Shorts ideas to try:

• Share quick tutorials
• Post customer reactions
• Tease full-length videos

Visme, for example, uses Shorts for quick how-tos and turns to long-form for more detailed explainers.

Keep the energy high and make your point early. If people watch until the end or rewatch it, YouTube is more likely to show your Short to others with similar interests.

4. Write clear, searchable titles and descriptions

Your title is one of the first things YouTube uses to understand your content. It also helps viewers decide whether to click.

Here’s what helps:

• Use keywords your audience is already searching for
• Make the title specific and easy to understand
• Avoid vague phrases or overused hooks

In your YouTube description, add extra context, link to related videos and include natural keyword variations. This helps your video get discovered across both YouTube and Google. Here’s how we do it at Sprout:

5. Create eye-catching thumbnails

A thumbnail can influence whether someone clicks, even more than the title. That’s why it’s worth investing time into the visual.

Here’s what to aim for:

• High contrast and strong visuals
• A clear focal point, like a face or product
• Text that’s large enough to read on mobile
• A design style that matches your brand

Here are a couple of thumbnails from WHOOP’s video library:

Your thumbnail should pique curiosity, while still being clear about the content inside. Avoid misleading or clickbait thumbnails as they can negatively impact viewer satisfaction (and your performance).

6. Reply to comments and use community posts

Engaging with viewers is a strong signal of activity. When people comment and you respond, it encourages more interaction. And that extra engagement tells YouTube your video is creating interest and conversation.

• Reply to the first few comments within 24 hours
• Pin a viewer comment or add a follow-up question
• Use the Posts tab to share polls, updates or behind-the-scenes posts

Here’s an example from Canva:

This helps your channel stay alive between uploads and keeps people coming back.

7. Group videos into playlists

Playlists make it easier for viewers to watch more than one video at a time. This increases total watch time, which the algorithm pays close attention to.

Use playlists to:

• Organize videos by theme, topic or audience level
• Create natural next steps, like a tutorial series
• Keep viewers on your channel longer

International brand Ben & Jerry’s, for example, nicely organizes their videos by country:

8. Collaborate with others in your industry

Partnerships and collabs put your channel in front of new viewers who already trust the person you’re working with. This helps you grow your audience faster than relying on search or algorithmic recommendations alone.

Look for:

• Brands or YouTube influencers with overlapping audiences
• Industry experts willing to share their insights
• Cross-promotion opportunities on each other’s channels or social platforms

Insta360 often features top influencers in their cinematic videos promoting their products.

9. Use analytics to shape your strategy

YouTube Analytics gives you data-driven feedback on what’s working.

For example, reviewing your top-performing videos can help you understand what topics, formats or lengths your audience prefers.

You might also want to keep an eye on:

• Average view duration (how long people watch)
• Audience retention graphs (where they drop off)
• Traffic sources (how they found your video)

Use these insights to improve future content, double down on what works and adjust anything that’s consistently underperforming.

You can also use a third-party tool like Sprout Social to dig deeper into premium metrics you might not be able to uncover with YouTube’s built-in analytics. Sprout also makes it easier to compare performance across videos and even different social platforms.

10. Add captions and alt text for accessibility

Adding closed captions is extremely helpful, even for discoverability and retention. Viewers watching without sound (which happens often on mobile) can still follow your message.

Here’s what to do:

• Use YouTube’s captioning tools or upload your own .srt files for accuracy
• Add alt text in your video metadata and thumbnail image filenames
• Translate captions into multiple languages to expand your global reach

Captions can also feed into YouTube’s indexing, which helps your videos show up in more searches.

Shopify captions some of its videos in multiple languages to reach a wider audience, like when they’re promoting a new product or feature (below).

11. Add chapters and timestamps to improve navigation

People don’t always want to watch a full video from start to finish. Chapters and timestamps let them skip straight to what they need, like a specific tip, step or section.

This kind of control keeps viewers happy and more likely to keep watching. It also helps with SEO: chapters can show up in Google search results as clickable snippets.

12. Use a mix of content formats

Viewers have different preferences. Some want a quick tip, others want a full walkthrough or case study. Giving your audience variety helps you reach more people. And it helps YouTube understand the different ways your content can be used.

Try mixing:

• Educational tutorials
• Product explainers
• Customer stories
• Shorts for quick engagement
• Live streams or Q&As for deeper connection

This variety gives you more data to work with and keeps your channel from feeling repetitive.

13. Make your videos easy to watch on mobile

The majority of YouTube views come from mobile. If your video is hard to follow on a small screen, it’s more likely to lose viewers early.

Make sure:

• On-screen text is large and readable
• Visuals are clear, even on smaller displays
• Pacing is fast enough to hold attention without overwhelming

It’s a good idea to preview your videos on your own phone before publishing. Fixing small mobile issues can have a big impact on retention.

14. Use end screens and cards to keep people watching

End screens and cards help you suggest more of your content at specific timestamps, like at the end of a video or during a key moment.

Link to something related so it feels like a natural next step. Use the last 5–20 seconds for your end screen. The goal is to guide people deeper into your content, not just end the video.

Here’s an example of an end screen from a Sprout video:

15. Cross-promote your videos on other platforms

Don’t rely on YouTube alone to surface your videos. Promote them across your other channels, like social media, email newsletters, blogs or even within your product.

For instance, you could:

• Share direct links on Instagram Stories or LinkedIn posts
• Include video previews in your emails
• Embed YouTube content in your blog posts or landing pages (like Ahrefs does below)

This gives your content an initial push, which helps the algorithm detect early engagement. Sometimes, that’s just what it needs to show your video to more people.
