How YouTube Tags Work
YouTube tags are metadata that tell YouTube's algorithm what your video is about. While not as important as your title and description, tags still play a role in:
- Helping YouTube categorize your content correctly
- Matching your video with related video suggestions
- Appearing in searches for misspellings of your target keyword
In 2025, YouTube has confirmed that tags are a minor ranking signal compared to the title, thumbnail, and description. However, they remain worth optimizing — especially for new channels trying to establish topical authority.
How Many Tags Should You Use on YouTube?
YouTube allows up to 500 characters for tags. Best practice is to use:
- 5–15 targeted tags per video
- 1–3 exact-match tags (e.g., "youtube tag generator")
- 3–5 broader topic tags (e.g., "youtube seo", "youtube growth")
- 1–2 channel/brand tags
Avoid stuffing 50+ irrelevant tags. YouTube penalizes spam tag usage, and it can hurt your video's distribution.
How to Find the Best Tags for Your YouTube Video
- Use the YouTube Tag Generator — Enter your video topic and get 30–50 relevant tag suggestions instantly.
- Spy on competitor tags — Use the YouTube Tag Extractor to see what tags top-ranking videos in your niche use.
- Start with your primary keyword — Your first tag should be your exact target keyword, written exactly as you want to rank for it.
- Add variations and related terms — Include synonyms, related topics, and common misspellings as additional tags.
- Include your channel name — Adding your channel name as a tag helps YouTube suggest your other videos after someone watches one.
YouTube Tags vs. YouTube Hashtags
These are different features:
- Tags — Hidden metadata that only YouTube's algorithm sees. Added in the Tags field when uploading.
- Hashtags — Visible in your video description and above the video title. Clickable links that group videos by topic. Use 3–5 hashtags maximum per video.
Use the YouTube Hashtag Extractor to see which hashtags high-performing videos in your niche use.
Frequently Asked Questions
Do YouTube tags still matter in 2025?
Yes, but they are a minor ranking factor. YouTube's algorithm primarily uses your video title, description, thumbnail, and watch time data to determine rankings. Tags help with categorization and can assist with appearing in related videos, but they should not be your primary SEO focus.

Use the YouTube Tag Extractor on FreeToolsAll. Enter the URL of any YouTube video and the tool will reveal all the hidden tags the creator added. This is useful for analyzing competitor strategies.
What is the YouTube tag character limit?
YouTube allows a maximum of 500 characters for all tags combined. Each individual tag can be up to 30 characters. Most creators use 10–20 tags averaging 20–40 characters each.
Should I use the video title as a tag?
Yes. Including your exact video title as one of your tags is a well-known YouTube SEO strategy. It reinforces the primary keyword signal and can help your video appear when people search for that exact phrase.
