In the ever-evolving landscape of social media, hashtags have sparked countless debates among marketers and users alike. Are they still worth the effort, or has their significance diminished with the rise of advanced algorithms and smarter sorting systems? As we approach 2025, the digital marketing community is asking: should hashtags remain a cornerstone of our social media strategy? Let’s explore the state of hashtags and how they fit into today’s marketing ecosystem.
The rise and fall of hashtags
For over a decade, hashtags have been a staple in social media marketing, offering users a simple way to categorise content, increase visibility, and join trending conversations. The concept was revolutionary – users could attach a symbol (#) to relevant keywords, instantly grouping their posts with others in the same conversation.
But fast-forward to 2024, and the landscape has drastically shifted. New platforms like Threads introduced a one-tag limit per post, signalling a broader move towards context-driven content discovery. Meanwhile, platforms like LinkedIn prioritised keywords and conversation topics over hashtags, making it clear that semantic search is taking the reins. Algorithms no longer rely solely on hashtags to surface relevant content – they’re now capable of understanding the context and intent of your post based on its metadata, caption, and user interactions.
This evolution has rendered hashtags less crucial for systematic discovery, particularly on platforms that have embraced AI-driven sorting systems.
A call to abandon hashtags?
In a surprising twist, some platform leaders have outright discouraged the use of hashtags.
- Elon Musk, owner of X (formerly Twitter), publicly urged users to stop adding hashtags, stating they’re no longer necessary for visibility under the platform’s improved algorithm.
- Adam Mosseri, head of Instagram, echoed this sentiment, noting that hashtags provide minimal reach benefits and have little impact on engagement. Instagram even went so far as to remove the option for users to follow hashtags, doubling down on a personalised content strategy rather than a trend-based one.
While hashtags still have a role to play in aligning content with specific communities or niche conversations, research suggests their ability to boost reach has been largely overstated. According to LinkedIn expert Richard van der Blom, hashtags on LinkedIn no longer significantly expand post reach – a finding that’s consistent with feedback from other major platforms.
Do hashtags still have a role in social media marketing?
While their systematic importance has faded, hashtags aren’t entirely obsolete. In fact, they continue to serve a few niche but valuable purposes, including:
- Community Building: Hashtags like #SmallBusinessSupport allow users to connect with like-minded individuals, fostering a sense of community.
- Event and Campaign Tracking: For live events or branded campaigns, hashtags provide a way for participants to track updates and conversations. Think #Oscars2025 or #VMAs2025.
- Brand Identity: Custom hashtags can reinforce brand messaging and encourage user-generated content. For example, #TheBusinessTea or #ShareaCoke.
However, the golden rule is quality over quantity. Spamming your posts with a dozen hashtags – once a common practice – is now seen as unnecessary, if not counterproductive.
The future of hashtags: strategic use in 2025
As algorithms grow smarter, marketers need to rethink how hashtags fit into a modern social media strategy. Here’s what to keep in mind as we move into 2025:
1. Focus on relevance, not volume
Instead of using 30 hashtags on Instagram, experiment with 3–5 highly relevant ones that resonate with your target audience. Keywords and context now take precedence, so overly generic tags like #Love or #Happy are unlikely to move the needle.
2. Use hashtags for niche audiences
Hashtags still work well in specific contexts. For example:
- TikTok: Hashtags like #BookTok help users find niche content and communities.
- Pinterest: Although hashtags are less critical here, they can enhance keyword searches for highly specific topics.
3. Test platform-specific strategies
Different platforms treat hashtags differently. While X and Instagram may devalue them, TikTok’s discovery algorithm still relies on tags. Experiment with platform-appropriate strategies and adjust based on performance metrics.
4. Leverage semantic search
Platforms like LinkedIn and Instagram are now optimised for semantic search, which means the context of your content matters more than explicit tags. Focus on crafting detailed captions and incorporating relevant keywords organically into your posts.
5. Monitor trends in real time
Stay informed about algorithm updates and trends. Platforms frequently change their discovery methods, so a strategy that works today may not work tomorrow. Use tools like Google Trends or platform insights to adapt quickly.
As we approach 2025, the focus should shift to creating high-quality, personalised content that resonates with your audience. Algorithms are better than ever at detecting topical relevance, making hashtags more of a supporting role than a leading one. Use them sparingly and strategically, but don’t expect them to drive your entire growth strategy.
