Are Hashtags Still Relevant?
Once the go-to strategy for getting seen on social media, hashtags are no longer the silver bullet they once were. But that doesn’t mean they’re obsolete. As platforms evolve and content discovery becomes smarter, the way we use hashtags today needs to change too.
Understanding where and how hashtags still matter can help you fine-tune your digital marketing strategy.

Where hashtags still make an impact
Hashtags are still relevant on Instagram, especially for reaching new audiences in niche or local markets. But the trend now favours quality over quantity. Using 3-5 highly relevant hashtags helps your content reach people who are genuinely interested.
Hashtags on LinkedIn help categorise content and improve discoverability within professional communities.
TikTok
TikTok remains heavily hashtag-driven. Hashtags not only guide discovery but also help you tap into trending conversations and viral content. Using trending or community-focused hashtags can expand your reach.
YouTube
Hashtags work a bit differently on YouTube compared to other platforms. YouTube uses hashtags for categorisation and search, but they aren’t essential for discovery anymore. Their algorithm prioritises video titles, descriptions, keywords and watch behaviour over hashtags. That said, using 1–3 targeted hashtags at the bottom of your video description can still help your video appear in specific hashtag search results. YouTube will show the first three above your video title as clickable links.
Where hashtags are losing steam
Although you can add hashtags to Facebook posts, they don’t contribute much to visibility. Most users aren’t searching content by hashtags here, and Facebook’s algorithm relies more on engagement patterns and shares.

Hashtags still play a role during live events or trending news. But for evergreen or visual content, they’re less useful than they used to be. The platform now leans more on AI to recommend content based on user behaviour rather than just hashtags.
Pinterest no longer prioritises hashtags in search or discovery. In fact, Pinterest has shifted to a keyword-first model. Instead of using hashtags, you should focus on:
- Keyword-rich pin titles
- Optimised pin descriptions
- Alt text and board names
Pinterest treats hashtags like plain text now, so adding #socialmediatips is no more powerful than just writing “social media tips”.
What no longer works
Let’s bust some common myths:
More hashtags = better reach?
Not anymore. Overstuffing a caption with hashtags can actually reduce engagement or make your content appear spammy.
All hashtags help?
Only relevant hashtags that match your niche and audience will make a difference.
What to do instead
To get the most out of hashtags, focus on these best practices:
- Use 3 to 5 highly relevant hashtags per post.
- Mix broad and niche hashtags. For example, instead of just #art, try #australianwildlifeart.
- Incorporate location-specific and branded hashtags such as #rimidesigns or #australianmadeart.
- Ensure your captions and visuals align with your hashtags. AI-driven platforms now analyse text, images and audio for context.
Hashtags vs content context
One of the biggest shifts nowadays is how platforms use AI to understand content. Discovery is no longer limited to hashtags. Captions, keywords in your videos and even image analysis now determine reach.
So instead of relying only on hashtags, make sure your post:
- Includes relevant keywords naturally in the caption
- Has strong visual storytelling
- Is consistent with your overall brand voice and message
Final thoughts
Hashtags aren’t dead, they’ve just grown up. Used wisely, they’re still a valuable tool for targeting the right audience, especially for niche businesses. But they should be part of a bigger strategy that includes strong content, smart SEO and platform-specific tactics.
