Hashtags aren't dead — but the strategy has changed dramatically. Here's what the data says in 2026.
Optimal: 3-5 highly relevant hashtags (down from 30 in the old days). Mix: 1 broad (#marketing), 2 medium (#contentmarketingtips), 2 niche (#saasmarketing2026). Put them in the caption, not comments. Instagram confirmed captions perform better.
TikTok
Optimal: 3-5 hashtags. Always include a trending hashtag + niche hashtags. #FYP and #ForYou don't actually help anymore — use specific tags. Check TikTok's Discover page for current trends.
Twitter/X
Optimal: 1-2 hashtags per tweet. More than 3 = looks spammy. Use trending tags only if genuinely relevant. Branded hashtags for campaigns.
Optimal: 3-5 hashtags. Professional and industry-specific. #Leadership, #SaaS, #RemoteWork — keep it relevant.
YouTube
Optimal: 3-5 in the video description. YouTube also uses closed captions and title for discovery, so hashtags are less important here.
