How to use hashtags effectively in 2025

Hashtags work differently on each platform. On Instagram, a mix of niche and mid-size hashtags outperforms spamming 30 broad ones. On TikTok, hashtags influence the For You Page algorithm. On YouTube Shorts, they help with topic categorization rather than direct discovery.

Instagram hashtag strategy

  • Use 5–15 targeted hashtags, not the maximum 30 quality over quantity
  • Mix: 3–4 niche tags (under 100K posts), 5–7 medium (100K–1M), 2–3 broad (1M+)
  • Avoid banned or overused hashtags they can suppress your reach

TikTok hashtag strategy

  • 3–5 hashtags is enough TikTok's algorithm relies more on content than tags
  • Always include at least one trending hashtag relevant to your niche
  • #FYP and #ForYou are too saturated use niche-specific tags instead

YouTube Shorts hashtag strategy

  • Add 3–5 hashtags in the description YouTube shows the first 3 above the title
  • Use your main keyword as the first hashtag
  • Too many hashtags can result in YouTube ignoring all of them
