Using hashtags to drive business discoverability in the AI era
For business owners and marketing managers, the focus of a social media strategy has shifted from simple engagement to high-level discoverability. While the traditional use of hashtags has changed, they remain a key tool for establishing brand authority and ensuring your content reaches the correct professional audience.
The strategic role of hashtags in search
The role of hashtags has shifted from being a primary growth tool to a method of categorisation. They help social media platforms like LinkedIn, Instagram and Facebook and LLMs understand exactly what your post is about so they can show it to the most relevant audience.
For your business, using hashtags correctly provides several benefits:
- Market categorisation – they act as labels that tell the social platform to show your content to users interested in the tags used.
- Search authority – many users today still use hashtags in search bars to find businesses, and to hop on trends!
- Brand sentiment – using branded hashtags allows your business to track customer reviews and community interactions, which builds long-term trust.
How to use hashtags for reach and discoverability
To maintain a competitive edge, your approach to tagging should focus on precision and keyword relevance. We recommend following these guidelines:
Prioritising relevance over volume
Social platforms prefer 3 to 5 highly relevant hashtags per post. The focus on quality over quantity ensures the algorithm accurately identifies your target market, and ensures AI can pinpoint your exact area of expertise without getting distracted by irrelevant terms.
Adapting your strategy by platform
To maintain authority, you should adapt how you use hashtags based on the platform’s professional context:
LinkedIn – Focus on professional categorisation. Use 3 specific hashtags that relate to your industry, the topic of your post, or a specific professional community to signal expertise to decision-makers.
Instagram – While Instagram allows for more discovery based hashtags, you should still limit your selection. Use a mix of broad industry terms and specific local hashtags to help your business appear in both general searches and local explore feeds.
Facebook – Use hashtags to group content or highlight specific campaigns. Over tagging on Facebook can clutter your message and detract from your primary call to action.
Be specific to your industry
Generic hashtags often get lost in high-volume traffic. To build authority, use specific hashtags that relate to your service and location. For instance, a boutique law firm in Peterborough should use ones for their specific niche and the geographic area they serve to attract leads who are ready to purchase the product or service.
How to win in AI search
Search is moving towards Answer Engine Optimisation (AEO) – optimising your content so AI-powered search engines provide your brand as the definitive answer to a user’s question.
The clarity of your social media content affects how AI platforms recommend your business. Hashtags are no longer just for trending topics, they act as semantic signals that help AI powered search engines verify your niche. When your hashtags and captions are clear and direct, you make it easier for AI models to cite your business as an expert in your field.
Broad hashtags like #Business are too competitive and vague for AI search. Instead, use long-tail hashtags that mirror how people actually ask questions to AI.
- Instead of: #Lawyer
- Use: #FamilyLawAdvice or #SmallBusinessLegalTips
It’s best to capitalise the first letter of each word, as it’s much easier for AI (and humans) to break down and understand, for example, use #DivorceLawyer rather than #divorcelawyer.
Strong captions
It’s crucial to lead with a strong, informative caption. While hashtags help with categorisation, search engines and AI models now rely heavily on the actual text within your caption to understand the context of your post.
Keywords in captions vs hashtags
Keywords in captions provide the main information for AI models. You should use natural language and industry terms within your sentences to explain your service. Whereas keywords in hashtags act as labels for platform specific discovery.
For maximum discoverability, ensure your most important keywords are integrated into your caption text rather than relying on hashtags alone to do the work.
Refine your social media strategy
Managing multiple platforms while adapting to shifting algorithm trends can be a significant challenge. We move beyond simple engagement as we align your content with AEO standards. This ensures your business is discoverable not just on social feeds, but across the AI platforms your customers use to find expert solutions.
