Hashtags are no longer a shortcut to social growth, but they can still help platforms and people understand what a post is about. Used well, they support categorisation and discovery. Used as a block of generic labels under every post, they add noise without fixing weak content.
What hashtags can still do
A relevant hashtag gives a platform another contextual signal and can connect a post with a niche topic, event, location or community. It may also help a user who actively follows or searches that term. The effect is usually smaller than the impact of the creative, watch time, saves, shares and clear keywords in the caption, so hashtags should support the post rather than lead the strategy.
Choose relevance over volume
Start with the exact subject of the post, the audience it serves and any genuine local or campaign context. A Sydney accounting firm discussing payroll changes might use a small set covering payroll, small business and Sydney business. A broad tag with millions of unrelated posts is unlikely to bring a qualified customer.
- Use specific topic and industry terms that accurately describe the post.
- Add a location tag only when the content or offer is genuinely local.
- Create campaign or brand hashtags when you have a reason to group related posts.
- Avoid banned, misleading or unrelated trending tags.
- Write for humans first; keywords in clear caption copy matter more than a long tag list.
Test them like any other tactic
Do not judge hashtags by impressions alone. Compare reach from non-followers, profile visits, saves, shares, enquiries and the quality of new followers across similar posts. Change one part of the approach at a time and use enough posts to avoid mistaking one unusually strong result for a pattern.
The content still does the hard work
No hashtag can rescue a post that gives people no reason to stop. Strong social content begins with a clear audience, an immediate idea and a useful or entertaining payoff. Our guide to what works on Instagram and TikTok in 2026 covers the signals that matter more than tag volume.
