YouTube has become one of the most popular platforms for content creators to share their videos with the world.
With over 1.5 billion active users, it’s no wonder that so many people are trying to make a name for themselves on the platform.
However, with so many videos being uploaded every day, it can be difficult for creators to stand out from the crowd. That’s where YouTube SEO comes in.
YouTube SEO, or search engine optimization, is the process of optimizing your videos to rank higher in YouTube’s search results. By using the right keywords, tags, and descriptions, you can increase the visibility of your videos and attract more viewers.
In this article, we’ll take a deep dive into YouTube SEO and share some insights from our analysis of 1.3 million YouTube videos.
Methodology
To conduct our analysis, we used a dataset of 1.3 million YouTube videos that were randomly selected from the platform. We extracted various metadata for each video, including the title, description, tags, views, likes, dislikes, and comments.
We then used a combination of machine learning algorithms and manual analysis to identify patterns and trends in the data.
Key Findings
1. Keywords Matter: One of the most important factors in YouTube SEO is the use of keywords.
Our analysis found that videos with relevant keywords in the title and description tend to rank higher in search results.
It’s important to research popular keywords in your niche and use them strategically in your video content.
2. Tags Are Key: In addition to keywords, tags play a crucial role in YouTube SEO.
Our analysis found that videos with more tags tend to rank higher in search results. Make sure to include a mix of broad and specific tags that accurately describe the content of your video.
3. Engagement is Important: YouTube’s algorithm takes into account factors like views, likes, dislikes, and comments when ranking videos. Our analysis found that videos with higher engagement metrics tend to rank higher in search results.
Encourage viewers to like, comment, and share your videos to improve their visibility.
4. Thumbnail Optimization: A visually appealing thumbnail can attract more clicks and improve your video’s performance in search results. Our analysis found that videos with custom thumbnails tend to rank higher than those with generic thumbnails.
Take the time to create an eye-catching thumbnail that accurately represents your video content.
5. Video Length Matters: Our analysis found that longer videos tend to perform better in search results. YouTube’s algorithm favors videos that keep viewers engaged for longer periods of time.
Consider creating longer-form content that provides value to your audience and keeps them watching.
6. Consistency is Key: Consistently uploading high-quality content can improve your channel’s performance in search results. Our analysis found that channels with a regular upload schedule tend to rank higher than those with sporadic uploads.
Develop a content calendar and stick to a consistent posting schedule to boost your channel’s visibility.
7. Collaboration Can Boost Visibility: Collaborating with other creators can increase your video’s visibility and attract a wider audience. Our analysis found that videos featuring collaborations tend to rank higher in search results.
Reach out to other creators in your niche and explore opportunities for collaboration to expand your reach.
YouTube SEO is a powerful tool for content creators looking to increase the visibility of their videos on the platform.
By using the right keywords, tags, and descriptions, optimizing thumbnails, and engaging with your audience, you can improve your video’s performance in search results and attract more viewers.
Our analysis of 1.3 million YouTube videos revealed key insights that can help you optimize your content and grow your channel.
By implementing these strategies, you can increase your chances of success on YouTube and reach a wider audience with your videos.
Longer Videos Outrank Short Videos
When it comes to video SEO, should you create short videos? Or are you better off with longer videos that cover a topic in-depth?
We analyzed our data to find out.
Our data shows that longer videos tend to significantly outrank short videos.
In fact, the average length of a video ranking on the first page of YouTube is 14 minutes, 50 seconds.
What’s happening here?
YouTube has publicly confirmed that a video’s total watch time is a key ranking signal.
Also, in 2015, Google was granted a patent for an algorithm that uses “watch time” as a ranking signal.
In short, YouTube wants to promote videos that keep people on YouTube for a long period of time. Longer videos accomplish this best, hence the preference for longer video content.
Another theory is that longer videos provide more overall value in a single video.
This is true for “how-to” videos as well as for content designed to entertain. The value that longer videos provide may encourage more interaction signals (including comments and likes) that ultimately impact rankings.
In fact, if you do a cursory search of popular keywords, you’d be hard-pressed to find a short video (< 3 minutes) ranking highly in the search results.
Key Takeaway: Longer videos perform best in YouTube search. The average video on the first page of YouTube’s search results is 14 minutes, 50 seconds long.

Video Shares Are Strongly Tied to Higher Rankings
Google has consistently denied the fact that social signals play a role in their algorithm.
However, YouTube’s algorithm works independently of Google. So there’s a possibility that YouTube uses shares from social media networks like Facebook, Twitter, and LinkedIn as a ranking factor.
In fact, we did find that shares have a strong correlation with higher rankings in YouTube:
It’s important to note that we used YouTube’s public share report for this analysis.
Why is this important?
One of the major issues of using social shares as a ranking signal is that they’re easily gamed. Anyone can hand someone a few dollars in exchange for sharing a piece of content 100 times on Facebook.
This isn’t the case on YouTube.
Unlike sharing content using a webpage’s social sharing icons, YouTube knows which users share video content…and where they share.
This tracking makes this signal much harder to game.
Combine that with the fact that YouTube encourages publishers to create highly-shareable content (and that YouTube reports shares in YouTube Analytics), and you have a strong possibility that the relationship between shares and rankings is more than a chance correlation.
Key Takeaway: Highly-shared videos outrank videos with fewer shares.

A Video’s View Count Is Significantly Correlated With Rankings
Video views used to be YouTube’s #1 ranking factor.
The thought was that: lots of views=popular video=quality video.
However, YouTube discovered that views often serve as a poor indicator of video quality.
So they changed their algorithm to emphasize factors like audience retention and engagement:
However, we discovered that a video’s total view count continues to have a significant correlation with rankings.
It appears that you still need a critical mass of views to rank in YouTube. (In fact, a YouTube engineer stated that, while views aren’t as important as they once were, YouTube still uses them).
That’s because, without views, your video can’t generate the other signals that YouTube uses to evaluate your video’s quality (like total watch time and comments).
But at a certain point, views have diminishing returns.
That’s why you often see high-quality videos rank above lower-quality videos (even when the lower-quality video has significantly more views).
Key Takeaway: Video views are significantly correlated with higher YouTube rankings.
A Channel’s Subscriber Count Is Moderately Correlated With Rankings
We found a moderate correlation between a channel’s total subscribers and rankings:
This is good news if you run a small or new channel.
Unlike Google, which seems to have a preference for big brands, YouTube is more likely to rank content from “the little guy”.
For example, for this popular keyword, videos from two small channels outrank a video from a channel that has over 2 million subscribers:
This type of result isn’t uncommon on YouTube.
(Of course, channels with millions of subscribers have an edge. But our data shows that this advantage isn’t as significant as you may think).
Key Takeaway: Channels with lots of subscribers have an advantage on YouTube. However, videos from smaller channels consistently outrank videos from popular channels.
![subscribers vs rankings](https://designdiverso.com/wp-content/uploads/2024/07/viz-1.png)
Videos With Lots of Likes Outrank Videos With Fewer Likes
It’s no secret that YouTube prefers videos that engage their audience.
And video “likes” serve as a powerful engagement signal. After all, likes are a crowdsourced way of evaluating how the YouTube community feels about your video.
That’s the theory. But what does the data say?
Our study revealed a significant correlation between likes and video rankings:
This suggests that YouTube may use likes as a ranking signal.
However, as you know, correlation doesn’t always mean causation.
Videos with lots of likes are also likely to be high-quality. And high-quality videos generate other ranking signals (like audience retention) that YouTube values.
Key Takeaway: YouTube may use likes as a direct ranking factor. Or it could be that heavily-liked videos generate other signals that YouTube truly cares about.
Videos That Result in New Channel Subscribers Rank Higher Than Videos That Don’t Generate Subscribers
If someone really enjoys a video on YouTube, what are they likely to do? Subscribe to that channel so they can see that channel’s future videos.
In other words, a video that encourages lots of new subscribers is a sure sign of quality.
Not only that, but getting new subscribers is an extremely hard metric to game at scale.
Sure, you can get a few people (or bots) to subscribe to your channel after watching a video. But it’s much more difficult than generating thousands of fake views or likes.
Knowing that, it’s likely that YouTube uses “subscriptions driven” as a ranking factor.
Our data did indeed show a significant correlation between “subscriptions driven” and higher video rankings.
![likes likes rankings](https://designdiverso.com/wp-content/uploads/2024/07/likes.png)
As they do with shares, YouTube displays the number of subscriptions driven underneath each video:
(Publishers can choose not to show this information publicly).
Like with most metrics, you can boost the number of subscribers your videos generate by creating world-class video content.
However, you can also ask viewers to subscribe:
I’ve found that a clear call-to-action to subscribe significantly boosts my “subscriptions driven” on each video.
Key Takeaway:
Subscriptions driven” has a reasonably strong correlation with higher YouTube rankings.
Keyword-Rich Tags Have a Weak Correlation With YouTube Rankings In the early days of online video, platforms like YouTube relied on metadata to understand your video’s topic.
For example, YouTube would analyze your video’s title, description, tags…even your video’s filename. Essentially, the more text you could attach to your video, the better.
Today, YouTube can “listen” to every word of your video (without needing you to upload a transcription):
![subscriptions driven subscriptions driven](https://designdiverso.com/wp-content/uploads/2024/07/subscriptions-driven.png)
Knowing that, does YouTube still use video tag metadata?
We found a weak correlation between keyword-rich video tags and rankings:
While tags don’t appear to be as important as they once were, our data shows that they still make a small dent. So it makes sense to use them.
(Also, YouTube recommends that you use descriptive tags. This suggests that they still use tags to understand the content and context of your video).
Key Takeaway: Including your target keyword as a tag may help with rankings. But the overall impact of tags appears to be small.
Keyword-Optimized Titles Are Slightly Correlated With Rankings Traditionally, your video’s title was a piece of metadata that YouTube put a lot of emphasis on.
However, we found that including an exact keyword in your video title only has a slight potential impact on rankings:
These findings could mean a few things:
It could be that YouTube has de-emphasized the importance of video titles. However, this seems unlikely as YouTube has stated that: “Titles contain valuable information to help viewers find your videos in search results.”
What’s more likely is that YouTube has developed a deeper understanding of a title’s meaning (beyond simple keyword matching).
In other words, they may use a less-sophisticated version of Google’s semantic search. If so, YouTube wouldn’t need to see a specific keyword in your title to rank you for that query. A synonym would do the job.
In fact, it’s common to see videos ranking well in YouTube for popular keywords…even when they don’t contain the exact term in their title.
![tag keyword tag keyword](https://designdiverso.com/wp-content/uploads/2024/07/tag-keyword.png)
Key Takeaway: Using your target keyword in your title may help you rank for that term. However, the relationship between keyword-rich video titles and rankings is very weak.
There’s No Correlation Between Keyword-Optimized Descriptions and Rankings
For That Term Does including a keyword in your video description help you rank for that term?
According to our data, keyword-optimized descriptions don’t have any impact on rankings:
This finding contradicts a common “best practice” of video optimization: keyword-rich descriptions.
There are a few possible explanations for this finding:
First, like with titles, YouTube may not require an exact keyword in your description to understand what your video is about. For example, let’s say that your target keyword is: “how to grow tomatoes”. Using terms in your description like “growing tomatoes” and “the best way to grow tomatoes” may work just as well.
Second, there’s the possibility that YouTube uses “keyword appears in a video’s description” as a ranking signal, but it’s so small that we weren’t able to measure it. In fact, we found several videos with no description at all ranking highly on the first page. This implies that your video description isn’t nearly as important as user-generated signals (including views and “subscriptions driven”).
Third, it could be that YouTube now ignores video descriptions as a ranking factor. This is unlikely as YouTube states that: “Well-written descriptions with the right keywords can boost views and watch time because they help your video show up in search results.”
Despite this finding, I still recommend writing keyword-rich descriptions.
Why?
An optimized description helps you show up in the suggested videos sidebar, which is a significant source of views for most channels.
Key Takeaway: There’s no correlation between keyword-optimized descriptions and rankings for that term. However, I still recommend writing keyword-rich descriptions as they can help your video rank for related terms (and appear as a “suggested video”).
HD Videos Dominate The First Page of YouTube’s Search Results Do high-definition or standard-definition videos perform best in YouTube search?
We discovered that HD videos appear significantly more often than SD videos on YouTube’s first page:
This data can be interpreted in two ways:
First, it could be that YouTubers that create the best video content also tend to record in HD. Therefore, this is an instance of correlation only telling part of the story.
Second, there’s the possibility that YouTube has an inherent preference for HD video content.
It’s difficult to determine the full impact of HD vs. SD from our correlation data alone.
Regardless, the vast majority of videos that rank well in YouTube are in HD. In fact, 68.2% of all videos on YouTube’s first page are in HD.
Key Takeaway: HD videos are significantly more common than SD videos on the first page of YouTube’s search results.
