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
