Want to get into the minds of your customers ahead of the Christmas rush? You need to be shouting about your product on social media. Recreating trends is the best way to boost your brand’s online visibility and help secure those end-of-year sales.

I’ve visited small business accounts across TikTok and Instagram to find the top social media trends for December. I’ve included easy instructions and links to the trending social media sounds, so it couldn’t be easier to recreate them.

TikTok Trend: In Your 20s…

🎵 Trending sound: Silver Springs, Fleetwood Mac

Nine times out of 10, pushing yourself out of your comfort zone pays off. Creators have been reflecting on their past decisions and using this TikTok trend to encourage viewers to take that leap.

There’s no better way to close out the year than using this trend to look back on your business wins. Pinpointing a specific pivotal moment, such as when you had the idea for your most viral product or invested all your savings in your brand, will also inspire others.

How To Use This TikTok Trend

Click the linked sound and select “Use sound”
Add a collection of short clips that highlight your business wins. Examples you could use include:
- Speaking at events
- Opening your store
- Product photoshoots
Add the caption “In your 20s you will have a business you want to start. It’s very important that you start that business.”

Instagram Reel Trend: I Don’t Know What To Gift You

🎵 Trending sound: Original sound, Karyrommm

This Instagram Reel trend is a fun spin on the classic Christmas gift guide. The not-so-subtle Christmas wishlist shows short clips of creators opening products they want to receive in time to “All I Want for Christmas Is You” by Mariah Carey.

This video style is an easy, fun way to promote any seasonal products ahead of Christmas. Since this video is designed to be shared as gift inspiration, try to use complementary products that may secure you extra sales.

How To Use This Instagram Reel Trend

Click the linked sound and select “Use audio”
Film short clips opening the lids or caps of the products you want to receive to the beat of the music
Add the caption “I don’t know what to gift you” in quotation marks

TikTok Trend: Flow State

🎵 Trending sound: Sweet Little Surprises, Holly Warton

Have you ever lost track of time while binging your favorite TV series? Or been so locked in at a coffee catch-up that you missed your train? You have officially entered your “flow state” – according to TikTok – which is the feeling of being totally in the zone and forgetting everything else around you.

Businesses have joined in with this TikTok trend for December by showing exactly what makes them enter their flow state at work, whether it’s the Monday morning team debrief, having an uninterrupted email session at your favorite desk, or prepping for a product launch.

How To Use This TikTok Trend

At 2x speed, film a video of you or a colleague doing an activity that gets you in the zone
Add the caption “When [describe the activity] and I genuinely reach flow state”

Instagram Reel Trend: Come on Superman, Say Your Stupid Line

🎵 Trending sound: The Less I Know, Tame Impala

This Instagram Reel trend for December is your chance to call out the “stupid line” you hear all the time – whether it’s a friend, colleague, or a saying you’re personally guilty of.

This trend is best suited to client or customer-facing brands, since it’s the perfect opportunity to share the funny or frustrating requests you receive. Still, offices and freelance workers also use it to poke fun at themselves or colleagues.

How To Use This Instagram Reel Trend

Click the linked sound and select “Use audio”
Mouth the lyrics or film a product close-up
Add the caption “So come on Superman, say your stupid line” to the first half of the video
For the rest of the video, add your line in quotation marks. Examples I’ve seen include:
- “I’ll start tomorrow”
- “Is it lunch time yet?”
