I’ve been seeing this title ‘Hashtags are dead’ for a while now. It’s not strictly true. Adam Mosseri, Head of Instagram, has said that hashtags no longer have an impact on your reach. But they do still help to categorise your posts so you can use them to find like minded businesses, peers or competitors (e.g. #marketing coach in my case). But, they no longer push your posts to increase your reach and no longer drive social growth like they used to. They don’t boost discovery…they now function more like a label. They help platforms and algorithms categorise your content and give it context, making it more discoverable in search results. 

It’s now more about prioritising SEO (search engine optimization.) I know…this makes many people immediately switch off, but bear with me and I’ll try and make this much easier to understand. 

Why bother to use hashtags in 2026

Categorise your content

Hashtags still help platforms categorise your posts and tell the algorithm what your content says….e.g. This post is about marketing tips for small businesses, or This post is giving Easter gift ideas. 

SEO – hashtags as keywords

Hashtags are now acting more like searchable keywords, so this is worth thinking about. Focus on what your audience is searching for. For example, someone might be looking for a special gift for a relative who likes gardening. So, they type in ‘gift ideas for gardeners’ 

Your post appears because you used #giftsforgardeners and #gardeninggifts. 

Your hashtag strategy needs to focus on what your audience is searching for! It’s also worth including a couple of hashtags within your actual caption, as well as a couple at the bottom. 

Target your audience

As per my previous point, you want your hashtags to reach your target audience. You want to reach those that are interested in and care about your products or services. 

If you’re not sure what your audience search for, ask them! Publish a post asking what people would search for if looking for your type of product or service. You can then type this into a search engine, such as Google, and you will get loads more suggestions that people also search for. 

You can also ask AI, by typing in ‘I am a (what you do), I help (target audience), with (their problems or pain points). What SEO keywords should I use on Instagram? You can ask the same question for other platforms such as Facebook, TikTok etc. 

Then it’s about finding which ones work best for you. 

Longevity 

If you use the right hashtags that are relevant to your content and your audience, your posts stay searchable for longer. A well optimised post can appear in searches for weeks or even months, giving your content long lasting results. 

Hashtags by platform

Instagram

Instagram likes to see hashtags for engagement.

• Use up to five, including location (if a local business), your business, industry specific and content specific.
• Put a couple in your caption as part of the wording.

Instagram wants more than hashtags. It wants strong hooks, saves, shares and consistent posting. If your content is weak, hashtags won’t help at all. 

Facebook 

Facebook doesn’t advise more than five hashtags, but the very latest I’ve seen is a maximum of three! I’ve just found this information whilst researching this article! 

• Use a maximum of three hashtags
• Use content related hashtags, location tag (if a local business), your own brand hashtags, or industry hashtag.
• Mix and match the hashtags dependent on your content. 
• Include in caption and/or at the bottom of post.

LinkedIn

LinkedIn hashtags are mainly for topic classification. 

• Use two to three hashtags
• Use one broad topic and one of two more niche or relevant hashtags 
• Put hashtags at the end of the post

B2B brand hashtags help align your content with conversations already happening on the platform. Reach is driven by relevance and engagement, not hashtag volume.

TikTok

TikTok’s algorithm is largely based on behaviour. It prioritises watch behaviour, such as how long someone watches a video, if it’s watched to the end or just a second or two. Hashtags help confirm what the video is about, but it’s the video itself that is more important.n

• Use two to four hashtags
• Avoid chasing trends unless it aligns with your brand
• Mix up content topics 

X (formerly Twitter)

It’s more about readability. Too many hashtags reduce engagement. 

• Only use one or two hashtags
• Keep them relevant and intentional or don’t bother! 

YouTube

Hashtags should be minimal. Titles, thumbnails and watch time have far more impact on reach than hashtags.

• Use one to three hashtags.
• Add them in the description, not the title or at the end.

In conclusion, hashtags haven’t disappeared and aren’t dead, but they aren’t working in the way many of us expect them to.

The old mindset of packing in as many as you can is no longer relevant. In 2026, they play a much quieter role. They help the algorithm recognise your brand helping it get discovered and categorises your content. But they no longer drive growth or expand your reach. It’s more about using hashtags strategically for SEO and keywords.
