Making the Most of Your Social Media Hashtag Calendar
While it’s great to have a bank of social media content ideas to dip into every month, they have to be the right type of content for your organisation. Check out our top tips for maximising the benefit of using trending hashtags in your social media strategy. 🤓
Use Relevant Hashtags
Make sure that the hashtags you use in your social media strategy are relevant to your organisation. Don’t create content to jump on the trending bandwagon for the sake of it, only choose the most meaningful hashtags for your audience.
Balance Your Content
The fastest way to disengage your audience is to post too much — don’t overload them with hashtags and awareness days. Decide on one or two hashtags each month, and craft quality, relevant content around them.
Listen to Your Audience
Social listening is an excellent tool for measuring the conversation around a hashtag. Determine whether creating content around a particular hashtag will give you the engagement and exposure that you’re looking for. Can you positively impact your audience with this content?
Analyse Hashtag Performance
If you’ve been using trending hashtags for a while, take a top-performing post as a benchmark to measure the performance of your other hashtag content on. By measuring, you can analyse what content works, and which awareness days resonate the best with your audience.
Optimise Your Hashtag Content
Give your content the best chance of gaining traction on a trending hashtag by optimising it. Aim to add value to your audience, by being entertaining, insightful or inspiring. Use visuals with your post, and add other hashtags where appropriate to get involved in related conversations.
Adding hashtags and awareness days into your regular social media schedule is an excellent way to diversify your content, get involved in other conversations, and connect with your audience on a more personal level.
