Instagram has shifted more in the last two years than in the previous five.

A platform that once rewarded huge hashtag blocks and generic growth hacks is now behaving more like a search engine than a social platform. Reels are dominating attention; visibility and captions matter more than ever.

The brand growth rules that once applied no longer do. One question keeps coming up, time and time again. Are Hashtags still worth it and do they even work?

The short answer: yes… but not like they used to.

Are Instagram hashtags dead?

Hashtags are still part of content discovery. But not in the way you think.

Once upon a time, hashtags helped you game reach and growth. But now, they are no longer the driving force of growth.

Now they’re context reinforcers. Helping Instagram group your content into relevant pools of discoverability.

This shift has been a few years in the making.

It began when the “Follow Hashtags” feature became deprecated in late 2024. This was a subtle but significant signal: Instagram was no longer prioritising literal hashtags as a means for people to find content.

Instead, Instagram began leaning more into ‘interest-based search’ i.e. the words people type, the topics that catch their interest, phrases captured in audio and on-screen text.

This meant that hashtags, as well as captions and description began to perform more like metadata.

This made them useful for categorising content. But as for the heavy lifting and the reach, visibility and growth. This was the turning point for hashtags no longer being the mechanism for reach. Two years on and the quality and relevance of your content matter far more than the selection of your hashtags.

The strength of your hook, an aligned caption, entertaining and engaging content. All of these things are now at the heart of the Instagram growth engine. We’re now in an age of relevancy over volume.

As a platform, Instagram is far more advanced and far more searchable. The old 30 hashtag model, has been quietly overtook by fewer, more relevant tags.

So hashtags haven’t died.

They simply aren’t Instagram’s main discovery engine anymore.

How Instagram discovery works now

Social discovery on Instagram is now powered by a mix of visual recognition, audio transcription, natural-language caption analysis and, of course, user behaviour.

This all serves the wider need for brands to build a strategic, platform-aware social media presence.

Instagram doesn’t need you to tell it what your content is about through hashtags. It reads, listens, interprets and tests content with users who have shown interest in similar and like-minded topics.

Instagram rewards content that fits how the recommendation system works – not content built around heritage tactics like hashtag stuffing.

How Hashtags have changed and what drives reach

Back when hashtags were a major signal it made strategic sense to fill your posts with popular, relevant hashtags and trending hashtags.

These terms and tags would, in theory, broaden your reach and amplify growth. Now they’re just one small part of a wider distribution model. That approach doesn’t work as a growth tactic, as it dilutes relevance.

Hashtag overuse weakens relevance and topical clarity. If Instagram can’t confidently categorise your post, and if the tags you do use don’t match the overall context of your content, then Instagram can’t confidently recommend it.

What drives reach is now far more behavioural.

Strong hooks that keep people watching. Content that answers a question and is relevant to a specific niche or interest. Meaningful watch time. Saves, shares, comments and captions that are written in searchable natural language.

This is what drives reach.

Instagram’s AI can contextualise your content in its entirety. Testing content with users who engage in similar themes and topics, amplifying posts that feel are delivering engagement and value.

Quality, clarity, relevance and searchability. This is what Instagram is looking for

Hashtags can support this clarity. But they cannot create it.

When Instagram hashtags still work

There are still moments when Hashtags can deliver value. Especially when they help Instagram understand exactly who your content is for.

Niche and geographically specific hashtags are a highly effective example of this.

Local businesses, tradespeople and service providers can still benefit from adding geographical, or service-relevant hashtags – like #PlymouthPlumbers or #AccringtonAccountants. That’s because they support local-intent driven discovery, while helping Instagram categorise content for people searching within that area.

When combined with clear, helpful content, these tags can genuinely support visibility.

Where they don’t work is in the broad legacy categories. Tag like #food #travel #likesforlikes and other generic, high-volume terms offer almost no discoverability now. Instagram doesn’t rely on these broad pools when deciding what content to recommend. Using these can reduce your topical clarity and bury your content in a sea of unrelated content.

That’s why hashtags won’t rescue content that lacks in relevance and engagement.

So, what, and how many hashtags should you use?

Three to five well-chosen hashtags… that’s the sweet spot.

It forces focus, helps categorisation and, perhaps most importantly, keeps any given piece of content aligned with what Instagram already understands about you and your posts.

So, you might want to consider:

• a single branded hashtag
• one or two niche or industry identifiers that reflect a wider social media content creation strategy
• one or two topic-specific hashtags tied directly to your chosen keywords

As for where those hashtags go. Is it in the caption, or the first comment?

Truly, it doesn’t matter any more. Wherever they are Instagram treats them the same. So this is more of a stylistic choice than anything technical.

Building a modern Instagram strategy

If hashtags are now the supporting act, your content and your captions are the headline stars, sitting within an intentional, KPI‑driven content strategy.

Start with strong hooks that reflect a real question, challenge or curiosity. Something your audience cares about. Pair this with a caption, written in clear natural language and a small selection of choice, relevant tags – not a wall of hashtags. Just clean helpful content that mirrors how people search and speak

Then curate and create content that serves its purpose. Ideally, as part of a joined‑up, multi‑format approach that uses all of Instagram’s formats to reinforce a consistent narrative.

Trends can be good. But use them sparingly. If all your output depends on piggybacking on viral moments, Instagram won’t be able to focus on what your content is really about. Then your relevance will suffer.

When you’re making Reels (and you should be making them – they remain Instagram’s most discoverable format) treat every layer as a signal. Audio, on-screen text, visuals, descriptions… everything contributes to Instagram’s understanding of your topic. Everything else is just noise.

Consistency is the biggest factor in building reach and viability. Not just consistency in posting – but consistency in messaging, creative style, tone and context.

Then there’s your profile.

It mattered before; it matters even more now. Use clear, descriptive keywords in the name field and bio to signal your niche and your knowledge. Make it obvious who you are and what you do.

In a search-led world, being easy to find needs to be a core part of your growth strategy. Supported by smart SEO, GEO, Digital PR and brand building across a diverse online ecosystem.

Final thoughts

Hashtags still have a place, but they’re no longer the lever that drives growth.

They sit in a wider, more complex ecosystem. One where relevance, quality and clarity matter more than what tags you choose.

They’re useful. But only in the right context and as part of a modern social visibility strategy that understands how people search and how Instagram groups serve up content.

The smartest brands treat hashtags as an experiment, not a fixed set. They review top-performing posts, not just by likes. But by reach, non-follower engagement, saves, shares and watch time for reels. The hashtag patterns on these posts are not the real reason behind content performance.

Then, they build optimal relevant clusters. Tied to themes, subjects, products or regions, and aligned with any broader international communications activity. They keep them tight and adapt where needed.

But they don’t place too much focus on them. The brands that are ‘winning’ on Instagram aren’t the ones that are chasing growth hacks. They are the ones who keep their broader content strategy sharp, relevant and aligned with their audiences.
