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

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
