I feel Like your titles are the ones which determine your success in the Youtube SEO
Titles are DEFINITELY undervalued and they play a much larger role in CTR than people give them credit for.

YouTube is the second largest Search Engine in the world (and owned by the first). While they are a video-hosting platform it is the majestic nature of their Search and Discovery systems (SDS) that truly makes YouTube amazing. What everyone refers to as ‘The Algorithm’ is actually a complex series of algorithms that essentially review your video and match it to the viewing habits of people looking for exactly what your video is about (as well as the advertisers looking to get in front of those people).

Some of this is largely out of our control. YT uses some really intricate AI to determine what is in your thumbnail, what is occurring in your video etc. But they still require a human element; YouTube wants information from you in order to help determine the correct audience for your video. We can provide insight in the form of four sections of your video’s metadata. Here we are going to break down each section, how they work and their value in the overall process of indexing your video.

Titles

This is the most important aspect of your videos metadata. YouTube realizes that the majority of viewers are going to see your thumbnail and read your title. Their split-second decision to watch or scroll away is determined by these two factors. As such they place the most emphasis on the value of the beginning of that title. The longer a title is the less value there is in the words/phrases included towards the end because YT realizes that the longer a title is the less likely someone is to actually read it entirely. While YT allows you 100 characters for a title the end of that will be cut off… the amount that is cut off is determined by the device you are viewing it on. Ideally you want your title in the 60-70 character range.

When implementing keyword phrases it is a good practice to have a set of 4-5 that you are targeting. Choose the one that is the ‘primary’ keyword phrase and that should be the beginning of your title. You can mix in multiple keyword phrases too, like this…

If your keyword phrases are:

Delicious chocolate cake

Chocolate cake mix

Cake mix recipe

Then the beginning of your title can be ‘Delicious Chocolate Cake Mix Recipe’ and that will include all three terms as keywords in your title. That’s 35 characters, so use the remaining +/- 30 characters to include something that is going to hook the viewer. This is where you craft something compelling.

You have to balance the information YouTube needs to index your video with a human element that compels clicks. It can be difficult and it takes practice. But this practice will make a dramatic impact on your ability to get clicks as well as rank in search and it can not be overstressed.



Descriptions

The next most important aspect of metadata is your videos description. It is also weighted; the first 200 characters of the description are more valuable than anything after so you want to include your best keyword phrases here. After a paragraph or two describing your video with your keyword phrases carefully crafted into the mix you should utilize the rest of your description for a variety of things that can benefit your discovery, your views and your wallet.

  • After the initial description paragraph you should include any pertinent links that are most important to you. Websites, affiliate links, links to other playlists and videos and a subscribe link are all recommended depending on what is most valuable to you. Anything that you use as a call to action in your video can be linked here; driving viewers to your description is your chance to drive them to the places that hold value for you off platform.
  • After these links include your video Chapters. Chapters give viewers the ability to jump to different section of your video… but more importantly each individual chapter is indexed on Google Search. So each chapter provides a new opportunity for your video to be discovered in Search. Pro-Tip; you want your viewers to watch as much of your video as possible so try to keep your chapter markers in the first 50%-60% of your video. You don’t want to drive them to a chapter that encompasses only that last 30 seconds of your video as there will be no video left to watch.
  • Contact information, disclaimers, credits and all the stuff that needs to be included but which isn’t pertinent to your average viewer should go after this.
  • Include your hashtags last. You can include up to 7 hashtags, the first three will be included at the end of your title.


Tags

These are the least important aspect of metadata. Note, they are not valueless. They simply are not as important as the title and description. Tags help YouTube to recognize the key topics that your video is about, but mainly for the purposes of misspellings and such. These days the real value in tags is that they allow the creator to see where they rank (if you are using a handy-dandy tool like TubeBuddy!). This gives you feedback into where you stand so you can make adjustments and improvements in your keyword research for future videos. YouTube doesn’t hold you solely to the tags you enter; they are indexing your video based on viewer’s watch habits. You can check this by going to your YouTube Studio Dashboard and seeing what the top search terms for your video are.

Captions

This is unconfirmed… but confirmed. YouTube has come out and said that they monitor what is being said in your video (most importantly the first 30 seconds) in order to measure its value to advertisers. But is that all they are monitoring? It stands to reason that since they are looking anyway, they are using Google Brain to astonishing lengths in your thumbnails and video content… so why would they not be listening to your video in order to determine its index placement? In addition to this YouTube is very likely listening not only to what is being said, but how it is said. We know that gunshots get flagged in videos as much as curse words do, and we know that YouTube caters videos to viewer based on their viewing habits. It is likely that YT has some metrics regarding the video style that viewers prefer, including how the audio is presented. Be mindful of this when you are targeting your audience; you may want to make music/volume considerations based on the audience you are looking to attract.

I can not speak to how YouTube does this or what they are looking at specifically, but we are provided the option of editing our captions. This is an important step in translating your videos as well, and something that more creators should spend time focusing on. Google often gets the things we say wrong, and it is not uncommon for Google to accidently put curse words into our captions. It is a good practice to review and edit your captions before you publish… and since you are there anyway you may as well translate your videos into different languages. If you are interesting in this I wrote an entire article on the this topic here:

Pick a couple keyword phrases... maybe like 2-3. And just makes those phrases the first three sentences of your description. For example, let's do a description for the following keyword phrases:

Mountain rain sounds, rain sounds asmr, best relaxing mountain rain sounds

Looking at the first two phrases they can actually be combined into a single sentence. Then the third phrase can be the second sentence, like this:

Mountain rain sounds ASMR video to help sooth you even and help you to relax. We've taken the best relaxing mountain rain sounds and put them together for this video so you can take the stress out of your day/night at work or home any time you like.

These are natural sentences and a very easy way to implement our keyword phrases into the description.

Hi Stanley,

Thank YOU for sharing that information - so many great tidbits in it - AND a couple of really solid golden nuggets for me as I'm struggling with my descriptions as I'm trying to make them informative, interesting AND YouTube algo search optimised.

Especially that DESCRIPTION portion one year after writing your post is definitely something I'm going to look into and apply!

Xavier

P.S. As @MattCommand1 cheekily said, thanks for giving us more work! BUT I'll happily do it all and more if that means my descriptions will be optimised! Finally

100% agree - I used to do test them myself back in BTB era (Before TubeBuddy), and now I'm constantly doing A/B TESTS, whether it's thumbnail vs thumbnail, or title vs title - which is why it's my most used feature of TB.

Great content, I feel the Captions in Videos are also important because the only way to get featured snippets on Google or important part in the video that solves problem is with the help of captions.

Nicht nur der Titel, sondern auch die Nägel – beide sollten für den Benutzer ansprechend sein, wenn beide korrekt sind, sollte es funktionieren.

Your breakdown of YouTube's metadata components and their significance provides valuable guidance for content creators. Balancing the need for indexing with the need to engage viewers is indeed an art, but mastering these techniques can significantly boost your video's performance on the platform. Thank you for sharing these insights!
