How to Find the Best Tags for Your YouTube Video

YouTube tags have become less influential over the past few years, but writing them off completely is a mistake. They still serve specific purposes, and using them correctly takes about two minutes per video — making them one of the easiest metadata optimisations available.

What YouTube tags actually do in 2026

YouTube uses tags primarily to understand your video's topic, particularly when the title or description is ambiguous. For most videos with clear titles, tags are a secondary signal. For videos with titles that could apply to multiple topics — a product name that exists across different industries, for example — tags help YouTube categorise the content correctly.

Tags also play a role in the "suggested videos" algorithm. Videos that share tags with a popular video are slightly more likely to appear in its suggested sidebar. This means strategic tagging around popular content in your niche can drive some additional discovery, even if the effect is modest.

Building the right tag set

A well-structured tag set for a YouTube video typically includes three layers:

• Broad topic tags: 2–3 tags that describe the general subject area. For a video about sourdough bread baking, this might be "baking", "bread making", "sourdough".
• Specific tags: 3–5 tags that match exactly what your video covers. "sourdough starter beginner", "how to make sourdough", "sourdough recipe for beginners".
• Long-tail tags: 2–3 longer phrases that match how people actually search. "how to make sourdough bread at home", "beginner sourdough bread recipe".

Include your video's exact title as a tag — or a close version of it. This reinforces the primary keyword signal. Total of 10–15 tags is a reasonable range; going up to the 500-character limit with dozens of tags provides minimal additional benefit.

Finding tags that work

The fastest approach: search your topic on YouTube and look at what terms appear in the autocomplete. These are real search phrases people use. Add a few to your tag list directly — they're already validated search queries.

Looking at successful competitor videos in your niche can also reveal effective tags. Browser extensions like TubeBuddy and vidIQ show you competitor tags if you want to investigate. For a free approach, an AI-powered YouTube tags generator gives you a relevant starting list based on your video topic that you can edit and refine.

What to avoid

Don't add tags that aren't relevant to your video just because they're popular. YouTube has stated this can actually harm your video's performance by sending confusing signals about your content's topic. Similarly, don't include competitor channel names in your tags — this is against YouTube's policies and can result in your video being removed.

Keep branded tags consistent. If you have a series or recurring format on your channel, use a consistent tag for all videos in that series. This helps YouTube group them and surfaces older videos when a viewer watches a newer one.
