Hashtag Science: Do We Still Need #Hashtags in 2025?

Spoiler: sometimes yes, mostly meh. Read this before you slap five random tags on your next post.
What changed?
- Hashtag followers vanished. LinkedIn killed the “follow #Marketing” feature in late 2024. Reach tanks if you still bet on it.
- AI topics stepped in. The feed now sorts posts by intent and dwell time, not blue links. Hashtags are just one weak signal.
- Some analysts even call hashtags “worthless in 2025.” Harsh, but the algorithm agrees for broad tags.
The numbers, no fluff
Setup | Avg. Likes | Key Take |
---|---|---|
0 hashtags | 10.8 | Baseline. |
1–3 hashtags | 14.7 | Sweet spot. |
6+ hashtags | 8.4 | Punishment zone. |
Statista pulled these stats from 2 000 posts in 2024. Small lift, but lift.
LinkedIn’s own docs still say “Use 3–5 relevant tags.” Keep it tight.
When hashtags still work
- Niche discovery. #SaudiFintech or #B2BPodcast—small crowds, big intent.
- Live events. Use the official tag. Instant lobby.
- Search crumbs. Users still filter by tag inside Search.
When to ditch them
- Generic spam. #Success #MondayMotivation = algorithm yawns.
- Over-tagging. Six tags screams “desperate.”
- Vanity tags. #MySuperCoolFramework? Congrats—only you follow it.
2025 Hashtag Game Plan
- Cap at three. Anything beyond hurts reach.
- Mix sizes. One large (100 k+), one mid, one micro.
- End of caption. Keeps hook clean.
- Test monthly. Track with Spiry analytics; double down on what drives clicks.
- Skip if irrelevant. Better no tag than a wrong one.
