Social Media Day is the one day of the year that's all about the platforms you use to reach your customers. It's the perfect excuse to thank your followers, show the people behind your account and give your social media a bit of a spring clean. And because it's about social media itself, it works for every business, whatever you sell.
Here are 25 Social Media Day post ideas for UK businesses, whether you run a shop, a cafe, a salon, a trade business or a B2B brand, plus example captions, hashtags and a few tips to get the most from it.
When is Social Media Day?
Social Media Day is on 30 June every year. It was started by Mashable in 2010 to celebrate the impact of social media on how we communicate, and it's now marked by brands, creators and communities around the world. It also lands right at the end of the first half of the year, which makes it a natural moment to review how your social media is performing.
- Same date every year
- Works for every business
- Perfect for a mid-year review
Why it's worth posting about
Most awareness days ask you to find a link between the day and your business. Social Media Day doesn't, because every business with a social media account already has one. It's a chance to say thank you to the people who follow, like and share your posts, to show a bit of personality and to remind people where else they can find you. It's also a great nudge to look at your own accounts and decide what you want from the second half of the year.
It's also in our free UK social media calendar, alongside 200+ other dates worth planning for.
