Although YouTube is owned by Google, it’s a unique platform with a different approach to algorithms and discovery to Google Search.

YouTube’s systems take a viewer-first approach, evaluating a user’s preferences and interests based on the data it has about their viewing habits and pulling lists of videos unique to that user.

It also prioritizes signs of video quality, especially user engagement and user satisfaction, much more than metadata.

YouTube search is one of several systems that deliver videos, and while you can rank for specific keywords and search terms, it’s also weighted heavily toward personalization and user satisfaction.

Many videos may not perform well in search but will draw traffic from other discovery systems on the platform – and user journeys don’t include YouTube Search much of the time.

Ranking on YouTube is only one part of a complex relationship between you, your content, and your audience. If you want to build a successful YouTube strategy, then you must expand your thinking beyond ranking.

How YouTube Can Benefit SEO

YouTube has two key benefits for SEO.

1. YouTube is the second-biggest social media platform, with 2.5 billion monthly active users. An effective video strategy can drive brand awareness and engage your audience. It can also create a unique revenue stream through advertising and channel memberships.
2. YouTube videos can also appear in organic Google search results, and there is a tab for “videos” in Google Search. A video strategy can be critical to user experience, depending on the audiences you serve and how they prefer to interact.

I feel strongly that you should learn about YouTube’s algorithms even if you’re not committed to a YouTube strategy.

YouTube is a Google property, and even though there’s unlikely cross-pollination between YouTube’s and Google’s algorithms, YouTube is an excellent look at what Google prioritizes when it has access to every data metric and every user journey.

It’s a closed environment that it controls, which does not describe Search (despite its best efforts). Learning to succeed on YouTube can absolutely make you a better SEO.

How Do Videos Rank On YouTube?

To understand SEO on YouTube, you need to understand how the algorithm works and what its different systems prioritize. YouTube has multiple systems that deliver videos to users.

Each system acts using different sets of signals. There are general algorithmic priorities and then specific functions of systems that weigh different signals in different ways.

Generally, the different signals the YouTube uses fall under two categories:

1. Personalization.
2. Performance.

Under these categories, there are hundreds of individual signals.

Signals that fall under personalization include:

• A user’s activity history tied to their account or browser.
• A user’s activity history in the current session.
• A user’s subscriptions, liked videos, notification preferences, and other interaction signals.
• Search terms that users input.
• Device type.
• Time of day.

Signals that fall under performance include:

• Total hours of watch time.
• Average view duration/percentage of video viewed.
• User satisfaction surveys.
• Whether users ignore a video or click “not interested.”
• Comments, likes, and subscriptions that a video generates.
• User behavior while watching a video (skipping forward or back).
• User behavior after watching a video (going back to their search, clicking on a new video, etc.).

For more information, watch the video below:

The Recommendation System

The first aspect of discovery we’re going to discuss involves video recommendations.

This term covers two distinct but closely related systems: a user’s homepage view and a user’s suggested videos view.

YouTube’s Creator Insider channel explains how the discovery systems work here.

The Homepage System

When a user visits YouTube, they have access to a homepage with video recommendations that are personalized for them.

This personalization is based on their activity history, what they like to watch, their subscribed channels, etc. The recommendations also consider signals of video quality and user satisfaction calculated by the algorithms.

To quote the video: “Home offers to deliver the most relevant, personalized recommendations to each viewer when they visit YouTube.”

The Suggested Videos System

Suggested videos (offered alongside the video a user is watching) are similar, grouped under the same umbrella of recommendations, but they use different signals. These recommendations priotize the experience of a user’s current session.

To quote the video: “Suggested offers viewers a selection of videos they’re most likely to watch next, based on their prior activity.”

While quality and user experience signals absolutely count in the suggested recommendations, they’re more heavily weighted toward satisfying a user’s immediate interest and intent.

This quote from the video is critical to understand, especially when we discuss different factors in YouTube’s algorithm later on: “YouTube’s recommendation system finds videos for viewers (rather than viewers for videos).”

The Search System

YouTube’s search system connects users with videos based on search terms they input, so it works a little more like Google Search.

It doesn’t weigh a user’s history quite as heavily to remain open to what they currently need.

Rather than trying to predict videos to suggest, it waits for user input and then uses available data (such as video topics, satisfaction metrics, and a user’s history) to serve results relevant to the query.

YouTube Search seems to be considered a separate feature. It prioritizes three core metrics:

• Relevance: How well a video’s title, description, and content match the query.
• Engagement: A video’s engagement statistics, such as watch time and other user signals.
• Quality: YouTube also uses E-E-A-T signals, a familiar phrase for SEO professionals.

The Shorts System

The Shorts system is unique. While it uses many of the same principles as other systems, each user has a separate Shorts watch history from their long-form video watch history.

There may be some crossover, but for the most part, any personalization signals are separate between Shorts and other types of videos.

Shorts has its own tab, as well as sections on other areas of the site such as the home page, in Search, and recommendations.

For more information, watch Shorts and the Algorithm.

The Trending System

The Trending system is different from other systems in that it isn’t personalized. It shows the same videos to all users in a country.

Here’s what YouTube says about how Trending videos are chosen:

“Amongst the many great new videos on YouTube on any given day, Trending can only show a limited number. Trending aims to surface videos that:

• Are appealing to a wide range of viewers.
• Are not misleading, clickbaity or sensational.
• Capture the breadth of what’s happening on YouTube and in the world.
• Showcase a diversity of creators.
• Ideally, are surprising or novel.

Trending aims to balance all of these considerations. To achieve this, Trending considers many signals, including (but not limited to):

• View count.
• How quickly the video is generating views (i.e., “temperature”).
• Where views are coming from, including outside of YouTube.
• The age of the video.
• How the video performs compared to other recent uploads from the same channel.”

YouTube Algorithm Ranking Factors

The first thing you need to understand about YouTube’s algorithm is that it is “all about the audience.”

Recall this quote from earlier:

“YouTube’s recommendation system finds videos for viewers (rather than viewers for videos).”

It’s audience-first every time. Responding to a question about whether it makes sense to change the thumbnail or title of a video, a product manager at YouTube said this:

“When you change your title and thumbnail, you may notice that your video starts getting more or fewer views. And that’s generally because your video looks different to viewers, and that’s going to change up the way that people interact with it when it’s offered to them in recommendations. Our systems are responding to how viewers are reacting to your video differently, not the act of changing your title and thumbnail.”

1. Watch Time, Engagement, And Satisfaction

As explained in the video links above, the primary metrics that YouTube’s algorithm is optimized for are engagement and satisfaction.

Clicks and views are important in this consideration, but the most important is watch time modified by satisfaction.

Watch time can be represented in a couple of different ways:

• The amount of time that a user watches a video.
• The percentage of a video that a user watches.

Raw watch time is a pretty good indicator of whether or not users like a video. However, the percentage of a video they watch can be a better indicator.

In the analytics of a video, YouTube shows you the number of views, the watch time in total hours, and also a graph that looks something like this:

Screenshot from author, September 2024

This is a helpful visualization of the percentage of viewers engaged with the video and when they stop watching. You can use this graph to examine how successful your video is at grabbing and keeping attention.

This is critical information for you about the quality of your video in the eyes of your viewers, and the algorithm is using it as part of the formula determining how engaging and satisfying your videos are.

YouTube also trains its algorithms with satisfaction data, primarily gathered through surveys. The surveys aren’t a direct factor in an individual video, but the combination of watch time and satisfaction trains the algorithms to recognize high-quality content.

If you want to optimize for YouTube, or use video to enhance your SEO efforts, the first and most impactful rule is:

Make a good video that your audience wants to watch.

2. User Engagement

User engagement factors also matter for ranking.

How users behave during their watch time and after they are finished watching (combined with when they finish watching) goes into calculating video performance. These data sources include:

• Whether a user skips forward during a video.
• Whether a user moves back to rewatch a video section. (This can result in an automated “most replayed” section on a video’s timeline.)
• How a user behaves after they finish watching. Do they:
  • Click on a new video in the suggested videos list?
  • Play the next video in the playlist?
  • Return to their search or homepage?
  • Close the session?

3. Video Title And Description

Just like websites in Google search, the title of a video is critical for helping users and search engines understand what content to expect.

However, it doesn’t act in the way you might expect. You should think about your title in terms of user experience first.

While it’s important to use keywords, your use of keywords will have much less impact than the CTR, watch time, and other engagement and satisfaction factors.

When it comes to your title, the most important consideration is how you set the stage for the video with your target audience.

Your title and video content are closely related, and you must ensure that the video delivers on the promise of the title – or at least begins to do so – quickly.

Optimizing your title for keywords can end up hurting you if it sets unrealistic expectations or makes the title less appealing.

Similarly, you should use descriptions in a way that helps users. The description should briefly describe the topic and what the user can expect.

It’s also a good place to put references from the video, links to other content the user may want to watch, and actions you may want them to take after watching, such as a link to your website.

A critical note for descriptions is that you should use them to add titled timestamps to your videos. Timestamps look like this:

0:00 Introduction

0:52 Chapter 1

02:02 Chapter 2

You wouldn’t want to use “chapter” – you would add a title that describes what that section of the video is about.

Doing this in the video description automatically adds sectioned chapters to the video timeline.

Google Search indexes these chapter titles and timestamps, so if you execute them carefully, Google can send users to a directly relevant section of your video. You can see this with the “key moments” feature in Google SERPs:

Screenshot from search for [how to train a dog], Google, September 2024

As you can see in the next screenshot, the “key moments” appearing on Google Search are taken directly from the video description on YouTube:

Screenshot from YouTube, September 2024

This is powerful SEO. Do not underestimate this feature for “how to” SEO queries.

It’s a very compelling reason that video should be part of your organic SEO strategy because video results can show up in the “All” tab as well as the “Videos” tab in Google.

If you don’t add these yourself, Google may automatically create video chapters from the transcript. It’s best to control this process yourself.

4. Thumbnail

While they’re not a type of text metadata that algorithms can directly interpret, thumbnails are critical as part of the click-through and watch time formula.

Along with your title, they can make the difference between users clicking or not or finding a video satisfying or not, depending on the expectations set by the image.

I should also note that with Google leaning into multi-modal neural networks, it’s not beyond the realm of possibility that algorithms may soon understand thumbnails in relation to a video’s content.

Thumbnails are a ranking factor insofar as they’re a critical part of engagement. The algorithm will respond to how users respond to your video. So, your thumbnail needs to set your video up for viewers, both to attract clicks and set reasonable expectations.

In fact, thumbnails are one of the most important things on YouTube. They’re the first thing a user sees and likely the first piece of information they use to make a decision about whether to click, as they’ll likely parse the image more quickly than the title.

5. Video Content

Video content is, of course, the primary determiner of quality and what users respond to, so it’s what engagement and satisfaction data is based on.

However, there are some specific ways that a video’s content impacts ranking.

Watch Time: If you create a good video that viewers like, you’ll get positive engagement and satisfaction signals.

Captions and Transcripts: If you don’t provide captions, YouTube automatically generates them and builds a transcript for a video. It uses the information from captions to determine what your video is about, which makes your video script a helpful source of metadata.

So, use important keywords early in your script. This is potentially relevant for Google Search as well as YouTube Search and other systems.

It’s a good idea to upload your own transcript with videos for YouTube to build the captions, as the AI will make mistakes.

Relevance: If users indicate or the systems determine that your video content is not relevant to your title, then your video is unlikely to perform well.

Similarly, if you use a “clickbait” thumbnail that sets users up to expect something that you don’t deliver on, that disappointment will be reflected in the data.

Remember that there is a dance to your title and thumbnail, and what happens with the user is much more important than your metadata optimization.

If you have high clicks but low watch time, that indicates that users were drawn in but didn’t like the video. If the opposite is true, it could indicate that users aren’t resonating with your title and thumbnail when they see them.

6. Subscribers And Notifications

Subscribers are a critical part of a channel’s success, and they can impact how a new video performs. New videos appear in the “Subscriptions” tab of users subscribed to your channel.

Additionally, if your subscribers have opted in to receive notifications, they will get a notification when your video goes live.

These views are a critical initial source of data, as they can help YouTube build an understanding of how viewers respond to your videos. If your subscribers like a video, YouTube has a lot of information to work with about how to recommend that video to non-subscribers.

In a video for Creator Insider, Todd Beauprè, YouTube’s Growth and Discovery team lead, said that the Subscription feed “offers a bit of a control over other variables” when it comes to diagnosing why a video could be underperforming. If your subscribers don’t like it, other people probably won’t either.

For newer creators, YouTube does have a team and systems in place to assist in finding audiences.

According to Beauprè, there are systems that show videos from new creators to new audiences based on the history and preferences of those users as a sort of test.

Either way, it’s important to look at the initial data coming in about a video to see if it’s satisfying the first audiences who see it. If it isn’t, YouTube may not continue serving that video based on the quality, engagement, and satisfaction signals.

7. Tags Don’t Matter

I feel like this needs to be said multiple times.

Tags don’t matter.

Tags don’t matter.

Anyone who tells you that optimizing tags is important is wrong, and they can come and fight me over it.

YouTube SEO Tips

As a companion to your organic SEO strategy or as its own strategy, YouTube can have a huge payoff.

But you should be careful when treating it like a marketing channel.

Success on YouTube is audience-dependent, and modern audiences are sensitive to marketing campaigns.

If you’re using YouTube as a channel to try and send more traffic to your website or some other off-platform goal, you’re going to have a hard time for a couple of reasons:

• If users are on YouTube, it’s because they want to watch videos. If you’re too aggressive with off-platform conversion attempts, it can turn viewers off.
• YouTube’s algorithm prioritizes in-platform engagement and activity. A successful video should entice a user to watch the whole thing and then find another video to watch, not end the session and convert.

That doesn’t mean you can’t use YouTube as an organic marketing channel. But you must deliver value to your audiences first and build a community on the platform if that’s the route you’re taking.

If you’re using YouTube to boost your organic search performance, you can consider video more of a supplementary strategy.

But again, you should focus on providing direct value and create videos that are user-friendly and informative, not promotional.

The video should be a companion to your content because it is more user-friendly than text and static images, or a strong alternative for users who prefer it.

Make A Good Video

Nothing else in this article matters unless you make a good video.

This is advice that I find to be missing in a lot of “YouTube SEO advice” type articles.

Sure, many will provide you with guidelines that sort of add up to making a good video, like research and scripting and editing, but the simple statement is missing: Make a good video.

What follows from that is a whole bunch of questions about what “good” and “high-quality” really mean and statements like “that’s vague advice” and “it depends,” but I actually find this to be a very helpful filter statement.

If you don’t know what “a good video” means for your niche and your audience, then I have a question for you:

Why are you considering a video strategy in the first place?

Go and find five videos from other creators that you know for a fact your audience likes. Then, write down all the things that make them good.

If you can’t do that, go back to the drawing board. Go and find out what a good video is, what it does, and why people like it. That isn’t competitor research; it’s understanding the medium in which you plan to work.

Making a good video can overcome poor optimization at any of the points discussed in this article or any other article. Perfect optimization cannot overcome the impact of a bad video or a video that viewers don’t like.

If you’re struggling to get traction for your videos, the first question should never be how well they’re optimized. Your first question should be: “Are the videos good enough?”

Audience Research

Don’t start your keyword research for videos until you’ve done audience research.

YouTube’s algorithm doesn’t take a video and decide who to send it to. It examines the preferences and history of users and then curates a selection of videos for each individual.

You must identify the audience for your videos, which could be a very specific subset of your existing audience or a new audience entirely.

What this audience already watches is of critical importance because YouTube has multiple traffic sources within the platform with their own systems that weigh ranking factors differently.

For many videos, the primary traffic potential comes from the recommendation systems on the homepage or suggested video features.

That makes understanding what your audience is already watching critically important. Build on existing topics on the platform. Watch videos in your niche and find ways to answer questions or provide content that they don’t.

It takes a very specific type of video to get traction in YouTube Search. Search is the part of YouTube that weighs metadata most strongly, but user satisfaction remains a critical factor.

The video cited above in “The Recommendation System” section mentions that “learning or how-to videos – they often get more views from search.”

You must understand not only the preferences and needs of your audience, but how they’re most likely to come across your video.

Not every video is built for YouTube Search, and if that’s the case, it won’t take off if you don’t understand the flow of the experience a user might come to your video from.

Keyword Research

Keyword research is important for videos that you’re targeting on YouTube or Google Search. It’s still important, but to a much lesser degree, when it comes to YouTube’s discovery systems.

What I mean by that is that the research is still important so that you understand the language users are engaging with, but there’s only so much optimization you can do. It’s much easier to over-optimize and sabotage yourself when it comes to recommendation systems.

I’m not saying you shouldn’t do it. I’m saying you need to understand your audience and traffic source, do your keyword research, and then choose how to approach your metadata based on the traffic sources you expect for your video.

There are automated tools that can assist you with keyword research, and I encourage installing at least the free versions of both of these tools.

There’s a lot of value you can get out of your existing keyword research process, but it’s important to understand platform-specific keyword trends.

Resources About Keyword Research:

Focus On Thumbnails And Titles

Thumbnails and titles are where you spend the majority of your optimization time. These are the hooks, and how you handle them can make or break a video’s performance (second, of course, to whether the video is good).

The primary goal of titling high-quality content is to set an expectation. That expectation should entice users.

Then, you must fully deliver on the expectation. If your title and video are harmonious in this way, and you’ve researched your audience to know that they will respond to the topic, then you have the makings of a successful video.

Titles are your core keyword opportunity for videos, in addition to your description and video content. Thumbnails are your biggest opportunity to entice a response in users.

YouTube is now offering in-platform A/B testing for video thumbnails, which can help you understand what resonates with your audience.

Like the title, your thumbnail should set expectations for the video. Some elements that work well include:

• Humans with expressions or poses that match the video’s tone.
• Keywords that your audience will understand as integral to the video’s topic.
• Artistic and metaphorical representations of a topic.
• Adhering to, or standing out from, a common color scheme or design philosophy that other videos use.

Multiple different styles and design philosophies can work.

Here’s a screenshot of a wildly successful video by YouTuber hbomberguy titled, “Plagiarism and You(Tube)” – it’s 4 hours long with 25 million views.

Honestly, it’s a masterclass in overcoming the pervasive narrative of short online attention spans – and it’s a great video (yes, as you can see, I watched the whole thing).

But the thumbnail isn’t very refined, is it? It’s a bit messy. There’s a bunch of people there, and it’s a mix of real photos and a pretty creepy cartoon guy back there in the corner. Hbomberguy himself isn’t making an exaggerated expression; he just looks sort of baffled.

This thumbnail is masterful at evoking tone. This is the sort of thing you should be paying attention to when it comes to aligning the expectations of your presentation with the impact of your video.

Screenshot from YouTube, September 2024

Below are a few video results from the search we did earlier: [how to train a dog].

As you can see, there’s a wide variety of thumbnails that are all effective in their own way while sticking to the common theme of the search. I’ve cut out the sponsored results.

The top result is interesting. I find it loud and visually unappealing, but it’s clearly working.

Now, we can’t say whether the thumbnail has a significant positive impact or whether the video is just so good that the thumbnail doesn’t matter. But to be the first result, we have to assume it gets a lot of clicks. So, the CTR is good, and the thumbnail is a big part of that.

So this search, then, is less about tone and more about how clear and visually striking the image is.

I haven’t watched any of these videos (and I don’t have a dog), so the algorithm doesn’t have a ton of specific personalization to work with. Still, your results may differ.

So, we’re back to audience research and specific query research. Intent could be a deciding factor in how you approach thumbnails.

Don’t Ignore The Comment Section

This will be the last point because I’m becoming long-winded.

Comments sections are more important than you might think. They have a ton of functionality, such as your ability to pin comments, that can supplement a video.

You could pin a comment to highlight a specific call to action for highly engaged users who scroll down to the comments. It’s also commonly used to issue corrections and updates.

Some creators choose to pin comments from users that they find to be particularly insightful, complimentary, or in some cases, inflammatory.

Engaging with commenters is good practice. These users, for one reason or another, are highly engaged. That means:

• There’s a lot you can learn about your highest-value audiences from what they have to say.
• Engaging with them builds a sense of community and feedback.

The Best YouTube SEO Is A Good Video

I want to come back to this point to end the article.

It really is all about the video and what value it adds to the user’s experience and your content.

You can overcome so many obstacles with a video that comes from a place of genuine understanding of your audience’s needs or excitement for the subject matter.

This should be what drives your video strategy, whether you’re using videos to empower your organic SEO or build a following on YouTube.
