Recommended hashtags	3 – 5
Max title chars	100 (visible before truncation: ~70)
Max description chars	5,000
Visible before "Show more"	~100 chars

The first 3 hashtags in the description automatically appear above the title as clickable links. For Shorts, use 1 – 5 hashtags.

Pinterest

Element	Limit
Max hashtags	20 per pin
Recommended hashtags	2 – 5
Max pin title chars	100
Max description chars	500
Visible before "More"	~50 chars (desktop)

Pinterest has deprioritized hashtags. Focus on keywords as natural sentences within the description for better SEO instead of relying on hashtags.

Threads (Meta)

Element	Limit
Max hashtags	1 per post (topic tag)
Recommended hashtags	1
Max post chars	500
Max with text attachment	10,500 (500 + 10,000 expandable)
Visible without expanding	First ~1 – 2 lines

Threads limits topic tags to one per post. The platform is not hashtag-driven — the algorithm prioritizes content from followed accounts mixed with recommendations.

Usage Tips

• Hashtags count against character limits on all platforms
• Front-load your message before the "more" truncation point
• On Instagram and TikTok, fewer hashtags now outperform hashtag-stuffing
• On LinkedIn, hashtags at the end of the post perform better than inline
• On Facebook, hashtags have minimal impact on reach — use sparingly
