### In short
- YouTube ranks search results by relevance, viewer engagement, and channel quality.
- According to YouTube, the most important metadata for video discovery are title, thumbnail, and description; tags play only a minor role.
- The main keyword should be included in the title and in the first lines of the description; each video's description should be unique.
- Chapters require at least three timestamps, the first must be 00:00, and each chapter must be at least 10 seconds long.
- A misleading title or unrelated hashtags violate the rules and may result in video removal.
You optimize a YouTube video by selecting one main keyword based on what people actually search for and using it in the title and first lines of a unique description. Then add chapters, captions, and a few related hashtags. However, content also matters: YouTube ranks results by relevance, viewer engagement, and channel quality.
### What does YouTube use to rank videos in search?
YouTube mentions three main areas: relevance, engagement, and quality. Relevance means how well the title, tags, description, and video content match the search query
.
- Relevance – matching of title, description, tags, and content itself with the query.
- Engagement – such as watch time for a specific video in response to a specific query.
- Quality – signals by which the system identifies channels with expertise, authority, and trustworthiness.
Results are also personalized based on a viewer's search and watch history, if enabled. YouTube also states that it does not accept payments for better positioning in unpaid search results.
YouTube SEO is therefore about making your video clearly described while ensuring people actually watch it after clicking. Metadata (title, description, tags, hashtags) will help your video reach viewers, but it's the content that must keep them engaged.
#### Does this also apply to recommended videos?
Partially. Recommendations on the homepage and next to videos, according to YouTube, are based mainly on playback behavior, likes, dislikes, subscriptions, feedback, and satisfaction surveys
, and also on channel reputation and quality. A good title and description mainly help by bringing the video to the right viewers who will watch it through.
### How to select keywords for a video?
A keyword is a term a viewer enters in search, for example 'how to replace a bike hub'. YouTube recommends identifying one or two main keywords that describe your video, and use them prominently in the title and description
.
- Write down what question your video answers. Phrase it the way a viewer would ask it, not how you would name it.
- Try the autocomplete. Start typing a query into YouTube search and watch what completions it offers. They show how people commonly phrase the topic.
- Check your own statistics. In YouTube Studio, in Analytics under the YouTube Search source, you'll find the search terms that have already led to your videos.
- Include synonyms. Besides Analytics, YouTube also mentions the Keyword Planner in Google Ads for finding popular keywords and their synonyms.
- Choose one main keyword per video. If one video targets three different queries, it's often better to create three shorter videos.
For a Czech audience, keep in mind that people write without diacritics or colloquially. Use the main form in the title, variants naturally in the description.
### How to write a video title so people find it?
The title should clearly state in up to 100 characters what the viewer will get in the video and contain the main keyword as close to the beginning as possible. The 100-character limit is mentioned in YouTube help for uploading videos
(as of November 2026), but in the app and in search results, a longer title is usually truncated.
- Put the main term at the beginning: "Replace a bike inner tube: 5-minute procedure" instead of "Today's video where I'll show you...".
- Promise only what the video will deliver. YouTube in rules against spam and deceptive practices
prohibits intentionally misleading titles, thumbnails, and descriptions designed to trick viewers into clicking.
- Don't use the same title for multiple videos. Differentiate them with a specific detail (model, year, level).
- The title and thumbnail should work together: the title states the topic, the thumbnail shows it. Don't literally repeat the entire title on the thumbnail.
### What to write in a video description?
The description explains to both YouTube and viewers what the video is about and can have up to 5,000 characters (as of November 2026). The first lines are most important because viewers see them before expanding the description, which is why YouTube recommends using them to describe the video content
.
- First 1–2 sentences: what the viewer will learn, with the main keyword in a natural sentence.
- More detailed paragraph: what the video covers, who it's for, what terms and synonyms will be mentioned.
- Chapters: a list of timestamps (see below).
- Links: related videos, playlists, your website.
- Hashtags: a few that directly relate to the video.
Each video should have its own unique description. Don't copy the same text under all videos and don't insert long lists of words into the description – YouTube explicitly states that excessive tags in the description violate anti-spam rules
.
### Do tags and hashtags still matter on YouTube?
According to YouTube, tags (hidden words added to the video) have only a minimal role in video discovery. Title, thumbnail, and description matter more. Tags are useful mainly for terms that people often misspell.
Hashtags are words with a # symbol in the description that can be clicked. According to help with hashtags
(as of November 2026):
- above the video title will be displayed up to three hashtags that the system evaluates as most relevant,
- if a video has more than 60 hashtags, YouTube ignores them all,
- a hashtag cannot contain spaces; multi-word expressions are combined (#VymenaDuse),
- unrelated hashtags may result in content removal according to deceptive metadata rules.
YouTube does not specify an ideal number of hashtags. It is sensible to use a few that genuinely describe the video, and monitor in your statistics whether they bring any traffic.
### How to add chapters and captions?
Chapters divide a video into named sections that appear on the timeline and help viewers jump straight to what they're looking for. You add them manually by writing a list of timestamps with names in the description.
According to tips for chapters
(as of November 2026):
- the first timestamp must be 00:00,
- the video must have at least three timestamps in ascending order,
- each chapter must last at least 10 seconds.
For new videos, automatic chapters are enabled by default (setting Enable automatic chapters in advanced settings). Manual chapters take precedence. Automatic chapters are not available if the channel has an active warning for violating rules or if the content may not be suitable for all viewers. Write chapter titles as brief descriptions of the content, by all means with keywords that are mentioned in that section.
#### Captions and Transcript
Captions make the video accessible to deaf and hard-of-hearing viewers and people watching without sound. YouTube can create automatic captions
in the video's default language, but you can upload your own caption file or a transcript text that YouTube will synchronize with the video.
YouTube's help does not explicitly state whether captions directly affect search ranking. However, it states that relevance is also assessed based on the video's content. Verified captions with correctly written technical terms and names are therefore useful, even if only for viewers' convenience. Always review and correct automatic captions in Czech.
### How to verify that optimization is working?
Monitor your results in YouTube Studio in Analytics, specifically in the traffic source YouTube Search and in search queries. Compare with an interval of several weeks, not day to day.
What to watch for What it says What to adjust
Search queries Which queries actually lead to the video Use them in the title and description of other videos
Impressions from search without clicks The video is shown but doesn't engage Title and thumbnail so they more accurately promise the content
Short watch time The video doesn't match expectations from the title Make the beginning of the video or title more accurately match the content
Skipping to a specific point Viewers are looking for a specific section Chapters, or possibly a separate shorter video

, for short videos in the guide how to get views on YouTube Shorts
.
### When paid promotion makes sense and when it does not?
YouTube's rules on false interactions prohibit anything that artificially increases the number of views, likes, comments or other metrics
, including third-party services. The video can be removed, repeated violations lead to warnings and the channel can even be terminated, so restrictions cannot be ruled out. The terms of service Sledujici.eu state this in Article 3.3 of the terms and conditions
also state: platforms do not allow the purchase of interactions.
Purchased subscribers or views do not replace optimization or content, do not guarantee viewer interest, reach in search or sales, are not a reasonable path to meeting monetization requirements and can worsen the ratio of interactions to the number of subscribers. A package like YouTube subscribers
can at best serve as initial social proof for a new channel that already has well-produced videos, or as a supplement to a specific campaign. If the channel lacks content, the channel already has a warning, or you're expecting genuine audience reactions, it doesn't make sense. Terms and variants can be found in price list
.
### Frequently asked questions
#### How long can a video title and description be on YouTube?
According to YouTube Help (as of November 2026), a video title can be up to 100 characters and a description up to 5,000 characters. However, longer titles are often truncated in search results and in the mobile app, so place the main keyword and the video's purpose at the beginning. You can verify the current limits directly when uploading in YouTube Studio.
#### Do tags help with better search placement?
Not much. YouTube states in its help that tags play a minimal role in video discovery, with title, thumbnail, and description being more important. Tags are mainly useful when people frequently misspell the video's main concept or write it without diacritics. A few tags are sufficient; excessive tags placed in the description violate anti-spam rules.
#### How many hashtags should you add to a YouTube video?
YouTube doesn't officially specify an ideal number, but sets an upper limit: if a video has more than 60 hashtags, YouTube ignores all of them (as of November 2026). A maximum of three appear above the title. In practice, choose a few hashtags that directly relate to the video; unrelated hashtags may result in content removal.
#### How can I find out which search terms people use to find me on YouTube?
In YouTube Studio, open Analytics, go to the Traffic sources tab, and look at the search terms under YouTube Search. You'll see which queries actually led to your video. You can then use these terms in the title and description of other videos on the same topic. For synonym ideas, YouTube also mentions the Keyword Planner in Google Ads.
#### Does it make sense to edit the title and description of an older video?
Yes, if the older video lacks a clear title or the description doesn't match what people are searching for. You can make the edit in YouTube Studio in the video details. Make changes gradually and after a few weeks compare the search views in your analytics. The video content won't change, so the edit will only help if the video itself actually answers the viewer's question.
