YouTube SEO: how to optimise your videos step by step

You can also listen on Spotify or watch on YouTube (in Spanish).

Your video is not competing only for a position. It is competing for the click and then for delivering what it promised.

That is where YouTube SEO comes in: answering a specific search, making sure the title and thumbnail explain that answer, and checking what happens when someone watches. Tags can wait. First, you need to know which problem you are trying to solve.

Short answer: YouTube SEO means preparing a video's content and information so it answers a search and is understandable both to the platform and to the viewer. Start with a specific intent, develop the answer properly, use a title and thumbnail that reflect the content, and review its performance in YouTube Studio. No combination of tags guarantees rankings.

What is YouTube SEO, and what is it for?

YouTube SEO aims to improve a video's visibility when someone needs content like yours. It is not limited to putting keywords in a description: you also need to choose which question you will answer and check that the video actually answers it.

In its explanation of search and discovery, YouTube says it considers the relationship between the search and the title, description and video content. It also considers the engagement videos generate for that search. Results are not simply a list of the most-watched videos.

That is why a video on configuring a microphone must solve that setup problem. A perfect title does not turn a ten-minute sales presentation into the tutorial the viewer expected.

The practical goal is to attract views from people who find the content useful. The raw view count does not, by itself, explain whether you have answered their need well.

How does search differ from recommendations?

Search starts with a query. The home page and suggested videos also draw on the viewer's context and behaviour. They are different discovery routes, although one video can receive views from several of them.

According to YouTube's documentation, factors on the home page include a video's performance with similar viewers and their watch and search history. Suggested videos may relate to the video being watched and may also be personalised.

This distinction changes how you read results. If views come from search, review which queries generated them. If they come from the home page, do not assume those people were searching for your keyword.

Do not confuse appearing on YouTube with appearing on Google either. Here, we are working on the video within YouTube. Ranking a page with an embedded video on Google needs a different analysis.

How do you choose a keyword and the video's intent?

Start with a question you can answer clearly. Then find out how your audience phrases it and what kind of content they expect. The keyword names that need; it does not replace the video idea.

Imagine a hypothetical example: you want to explain how to clean a moka pot. A step-by-step demonstration and a comparison of models answer different needs, even though both discuss coffee makers.

You can follow this process:

1. Write down the specific question you will answer.
2. Search for the topic on YouTube and treat suggestions as clues, not demand figures.
3. Review what the results promise and which formats they use. Look at the content, not only the title.
4. Check Studio's Trends tab if it is available for your channel.
5. Decide which answer you can offer and what does not need to be in that video.

The YouTube Studio Trends help explains its interest signals and content opportunities. Some features may depend on country, language or device. Not all channels see exactly the same things.

If you use Semrush to decide which articles to publish, keep the data separate. Keyword Analytics search volume is a monthly estimate for the selected search engine and database. Google Spain volume does not demonstrate how often that phrase is searched within YouTube.

In the article on keyword analysis, I explain intent and term selection for a website. Understanding the need is useful here too; figures from one platform do not transfer to another.

How do you write a title that helps people find and choose the video?

The title should tell viewers what they will find. Use the main phrase naturally and add the detail that distinguishes your answer. There is no need to turn it into a bag of keywords.

For the coffee-maker example, a suggested title would be "How to clean a moka pot step by step". If the content solves a particular difficulty, you can specify it. What matters is that the video delivers that promise.

YouTube recommends accurate, concise titles, with the important information first. It also distinguishes between titles aimed at search and titles that spark curiosity. The choice depends on the content and how people might discover it.

Before publishing, check whether someone unfamiliar with your channel understands what they will get. Then ask whether the video delivers it. If the second answer is no, adding another capital letter will not fix the problem.

What should the video description include?

The description should explain the content clearly. The first lines are useful for summarising the answer and giving context before the viewer expands the rest.

In its description tips, YouTube recommends giving each video its own description and featuring one or two main words in both the description and title. That does not mean repeating the same phrase on every line.

A practical structure might be:

• A brief explanation of what the video solves.
• The context needed to follow the steps.
• Chapters, where they help people find parts of the content.
• Resources and links that add to the explanation.

Do not make links the main attraction. If you link to a page on your website, explain what people will find there and make sure the resource is still available.

Tags have a much more limited role than they are sometimes given. YouTube's own FAQ says they mainly help correct common spelling mistakes. They are not a place to hide the strategy missing from the video.

What does the thumbnail need to achieve?

The thumbnail needs to communicate the topic and promise clearly. It should work with the title, not compete with it or advertise something the video does not offer.

Try viewing it at a small size. Check whether the main element is clear, the text is readable and the image represents the content. You do not need to fit every argument into a few centimetres of screen.

The official title and thumbnail tips stress representing the content accurately. Getting a click through an exaggerated promise does not prove you have found a good thumbnail.

Changing it does not, by itself, reset the rankings either. YouTube explains that changes in performance after editing a title or thumbnail depend on how viewers respond to that new presentation, not simply on the act of editing it.

How do you measure YouTube SEO without looking only at views?

Open YouTube Studio and look at where the audience comes from. Then connect impressions, clicks and viewing. None of those metrics tells the whole story on its own.

Impressions count the times a thumbnail was shown on the surfaces YouTube measures. Impressions click-through rate expresses how many of those impressions led to a view. It does not include every appearance of your video everywhere on the internet.

The help on impressions and CTR warns that the figure varies with the audience, content and where the video appears. Comparing videos with very different traffic sources can lead to the wrong conclusion.

Retention adds another question: what happens after people arrive? The key moments report lets you locate introductions, dips and spikes. A dip calls for reviewing that section; a spike may reflect interest, repeat viewing or a part that was not understood.

Use these signals to form hypotheses, not to deliver verdicts:

• If there are impressions but few clicks, review the title and thumbnail's promise, taking the traffic source into account.
• If people arrive and leave quickly, check whether the opening meets their expectations and gets to the answer.
• If unrelated searches appear, review what content you created and how you describe it.
• If a section is replayed, watch it before deciding it is the video's best moment.

On Google, it also helps to connect impressions and clicks. The reasoning of looking at context is useful; the reports and their definitions are different.

What should you review before and after publishing?

Before publishing, check that there is a specific question, a useful answer and a presentation faithful to the content. Afterwards, record what happened and decide what is worth testing.

This checklist may help:

• The video answers the intent you chose.
• The title is clear and does not promise more than the video contains.
• The thumbnail remains clear at a small size.
• The description explains this video, not a generic one.
• Linked resources work and make sense.
• You have separated search, home, suggested videos and other sources in your analysis.
• Any change has a recorded reason so you can evaluate it.

You do not need to declare a video a failure because of one isolated number or change five things at once. If you change the title, thumbnail and approach together, it will be harder to know what happened afterwards.

What questions often come up when starting?

Do you need to repeat the keyword many times?

No. Use terms that explain the topic naturally. YouTube connects the query with the title, description and content; repeating a phrase does not replace a useful answer.

Is there a good CTR for every video?

There is no single target for every channel and traffic source. Before comparing, check where the thumbnail was shown and to which audience.

Is a longer video always better?

Not simply because it lasts longer. YouTube recommends a length appropriate to the content and explains that it considers both absolute and relative watch time. Stretching an answer already delivered does not improve it.

Do you have to publish every day?

The official FAQ does not impose that requirement. Set a rhythm you can maintain with useful content. A full schedule does not replace a good answer.

To finish the coffee

YouTube SEO starts before uploading the file: choosing whom you help and what you will solve. The title, description and thumbnail must present that answer clearly. Studio then lets you review how the audience receives it.

Start with one video and one specific question. Record what you wanted to achieve, look at traffic sources and choose the next change for a reason. It is more useful than asking a tag to do the work of the whole channel.

In the next instalment, we will look at finding keywords for YouTube and distinguishing a useful clue from a figure belonging to another search engine.
