In this comprehensive guide, you'll discover how to find and use X (Twitter) hashtags that are relevant to your client's target audience:

A hashtag comprises two parts: the hash symbol — # - sometimes called the pound symbol in the US — immediately followed by a keyword or phrase. Ideally, use capitals for every individual word within the keyword or phrase, otherwise, it could get confusing.

Hashtags are a handy way to group and categorise tweets, and they help people follow topics they're interested in. Anyone searching for a specific topic can find relevant tweets immediately, without having to scroll through their X (Twitter) feed.

💡 Actionable pro tip for healthcare brands: While you should use some of these hashtags in your posts, you need to keep in mind that a lot of other, non-healthcare brands use some of these hashtags to raise awareness.
This is why you should use more specific hashtags to reach the right audience. You could experiment with combining location and service hashtags along with the above-mentioned ones (e.g. #blooddonation, #teethwhitening, #dentalsurgery, #periodontist, #cancerprevention).
💡 Actionable pro tip for eCommerce brands: Be aware that many marketers use these hashtags in their posts. To make sure you're targeting the right audience, you'll need to get a bit more granular with your hashtag strategy.

Forcing hashtags into your tweets to attract attention amounts to spam.
For example, if you choose to use a trending hashtag like #WinterOlympics, but your message and any links have nothing to do with the FIFA World Cup, you've attracted the wrong attention and audience. Even worse, if enough people complain, X (Twitter) might block your account. So don't go there!
Here are three ways to make sure they pass the relevancy test:
If you come across a hashtag but you're not sure what it means or whether it's relevant to your client's brand, you can check its definition by searching for it on a search engine like Google.
If one or more respected influencers in your industry or niche are using a hashtag, it's likely relevant. But you can still make your own check.
Enter the hashtag in the X (Twitter) search bar:
And see what content is being posted:
Incidentally, the hashtag was used more than 400,000 times, garnering more than 2 trillion impressions on social media.
