# How many hashtags should you use on social media?

> A handful of specific, relevant hashtags beats a long generic list on every platform that still uses them. Instagram tolerates more than X or LinkedIn, but relevance matters more than count everywhere.

Updated: 2026-09-24.

## Why "more hashtags" stopped being good advice

Hashtags used to work mainly as a discovery mechanic: more tags meant more chances to surface in a search or a feed. Most platforms have since shifted toward ranking content by relevance & engagement first, which makes a long generic hashtag list read as noise rather than reach.

A caption padded with fifteen loosely related tags also just reads worse, which costs more in engagement than the extra reach is likely worth.

## A reasonable starting count per platform

- **Instagram**: 3 to 5 specific, relevant tags works better than the old advice of maxing out at 30
- **X**: 1 to 2 at most, since hashtags compete with an already tight character count
- **LinkedIn**: 3 to 5, ideally ones with real follower bases rather than generic industry terms
- **TikTok**: a handful mixing a broad tag with a couple of specific, niche ones

These are starting points, not fixed rules. What matters more than the exact number is whether each tag is actually relevant to the post.

## Choosing which hashtags actually matter

- Specific enough that the audience finding it is likely to care about the post
- Active enough that a real conversation exists under that tag, not an abandoned one
- Consistent enough across posts that an account builds some association with a topic over time

A tag chosen because it's popular, rather than because it fits the post, usually attracts the wrong audience or none at all. Deciding on a small, deliberate set worth reusing, & sticking to it, beats reaching for whatever looks popular that week.

That consistency is easier to keep when the caption & its tags are drafted in the same place every time, which is exactly how DunSocial's composer keeps them.

## Where hashtags fit into the actual writing process

Deciding hashtags after the caption is finished, rather than as an afterthought while scheduling, keeps them relevant to what the post actually says rather than a generic list reused across every post regardless of topic.

DunSocial's composer treats hashtags as part of the same draft as the caption itself, written & reshaped per platform in the same pass, so a LinkedIn version & an Instagram version of the same idea can carry genuinely different tags instead of the same list copied across both.

## The honest limit of hashtags

Hashtags help a post get found by people not already following an account. They don't fix a post that isn't otherwise worth engaging with, & a strong caption with zero hashtags will usually outperform a weak one with a dozen well-chosen ones.

Treating hashtags as a small addition to good content, rather than a substitute for it, keeps the effort proportional to what they actually contribute. DunSocial's composer reflects that priority too, keeping hashtags a minor, editable part of the same draft rather than a separate feature demanding its own attention.
