Hashtag rules and limits on YouTube, Instagram, X and more

The short answer

Keep hashtags few and on topic: every platform here pushes back on piles of unrelated tags.

  • YouTube sets a hard number: with more than 60 hashtags it ignores every one, and over-tagging can take the video out of your uploads or search.
  • X cuts the reach of posts with excessive or unrelated hashtags, and YouTube may remove videos with misleading or unrelated ones.
  • Facebook shows content from accounts that stuff captions with hashtags only to their followers, and Instagram and Facebook don't recommend long captions unrelated to the video.
  • LinkedIn counts irrelevant hashtags as engagement bait, and Pinterest removes keyword stuffing.
  • Never tag a tragedy for views: YouTube demonetizes videos that add a sensitive event's keywords or hashtags to pull traffic.
  • And for US sponsored posts, the FTC says an #ad hidden among other hashtags doesn't count as a disclosure.

The rules, side by side

Each row is a platform's own rule: what it means, what the platform says, how to fix it, and where to read it in full.

Laws that apply on every platform

These come from laws and advertising regulators, not from a platform, so they follow you to every app in the places they cover.

Hashtags: laws that apply on every platform
WhereThe rule, in plain wordsIn their wordsLinks
USSponsored video without an in-video ad disclosure (US)Needs a disclosure labelThe creator has a material connection to a brand they mention or show (paid deal, free or discounted product, affiliate link or code, employment, family or personal tie) and the video itself has no clear disclosure. A disclosure that is only in the caption or description, only at the end, hidden among hashtags, or uses vague words like 'sp', 'spon', 'collab', 'thanks' or 'ambassador' does not count.Fix: Say it and show it at the start of the video, in the same language as the video: for example say 'This video is sponsored by X' and put 'Ad' or 'Paid partnership with X' on screen long enough to read. Keep the caption disclosure too, and also switch on the platform's paid-partnership label, but do not rely on the label alone. On a livestream, repeat it every so often.
“the disclosure should be in the video and not just in the description uploaded with the video.”
