And while it can be fun to create content, it’s always a downer when the post that you spent hours on perfecting doesn’t get the engagement you were hoping for.Plus, with so many trends popping up on the likes of TikTok and Instagram, it can be difficult to keep up with what kind of content you should be making.To help you out, we’ve rounded up five of the biggest social media trends small businesses can tap into for this month. With autumn here, it’s the perfect time to hop on seasonal trends, have some fun with your content, and get your customers excited for the season and your business.1. The click and peaceSound: Fun — Cortisa Star, soma, and venusgrl! (Soma Remix)Anyone who knows TikTok well enough knows that it’s full of fast, jumpy, and high-energy songs. Right now, the Soma remix of “Fun” has become the soundtrack for a specific type of video on the platform.The premise of the video is that the person (or people) pretends to cry on camera while the song plays, but then spontaneously winks and pulls the peace sign when the song’s clicking sound comes on.Popular TikTok brands like Little Moons and P.Louise have jumped on this trend, gaining 15.2K and 462.9K likes, respectively. There isn’t much reasoning behind this trend, aside from being a little silly. But sometimes, just having a bit of fun on social media can be just the thing to drive engagement and remind audiences why they love following you.Source: Little Moons (TikTok)Source: P.Louise (TikTok)2. POV: It’s September 1stSound: There She Goes — The La’sWhile many are sad that the summer season has come to a close, others are already hyping up the upcoming autumn. Just a few scrolls on TikTok or Instagram Reels, and you’ll find many videos of autumnal outfit inspo, baking recipes, decoration ideas, and a lot of references to Gilmore Girls.Creators and businesses have taken note of the hype, using the term “Pov – it’s September 1st” in their videos to set the scene for pumpkin-spice season.This is something F&B and ecommerce businesses can lean into, as it can help brands feel relevant, relatable, and part of the conversation their customers are already having. Even a simple nod to the change in season, like themed products or menu items, or a limited-time offer, can make content feel timely and boost reach.Source: theparkersmaple (Instagram Reels)3. PSA: She wants a boo basket this autumnSound: Duvet — BôaWe know what you’re thinking — what the heck is a boo basket?A boo basket is a Halloween-themed gift basket with seasonal-related treats and gifts, such as sweets, small toys, candles, and blankets. It’s a fun way to gift loved ones, and a great opportunity for ecommerce and dropshipping businesses to tap into the hype by offering their own boo basket bundles for customers.Trends like boo baskets are proof of how powerful seasonal gifting can be. Customers are always on the lookout for easy, ready-made options that feel thoughtful without needing a lot of effort. Even if you don’t sell traditional “gift basket” items, you can still join the trend by curating a small collection of your existing products with a Halloween or autumnal twist.Source: Nail Order Store (TikTok)4. Make it pumpkin-spicedSound: Lalala (audio from Gilmore Girls)Nothing quite says the beginning of autumn like pumpkin spice, and for coffee shops and cafes, pumpkin spice lattes are all the rage for the season.Starbucks has tapped into this demand with a video showing the vast number of comments they received from customers asking for the return of the drink (and of course, bringing it back to the menu). Even videos from regular TikTok users show just how popular pumpkin spice coffees are this season. Just typing in “pumpkin spice” on the platform’s search bar brings up tons of videos of users showing their Starbucks order and celebrating the return of the drink.For cafes, this is a clear sign that people want pumpkin spice right now. You can hop on a trend and give customers what they’re actually looking for and talking about online.Source: Starbucks UK (TikTok)Source: Lauren Findlay (TikTok)5. Dirty sodasSound: LUNA BALA (slowed) — Yb Wasg’ood, AriisDirty sodas have become a must-try on social media thanks to the success of popular US TV shows The Secret Lives of Mormon Wives and The Real Housewives of Salt Lake City. In case you haven’t heard of it, a dirty soda is a blend of fizzy drinks with syrups, milk, cold foam and cream.And now, American TikTok influencers have flocked to Froth, a Lisburn-based coffee shop that recently introduced the bizarre beverage to its menu. According to Northern Ireland World, demand got so high that Froth started to run out of ingredients and subsequently had to close its doors early.The dirty soda craze is a reminder of how quickly a viral trend can turn into a real-world demand. Customers love trying out what they’ve seen online or on popular TV shows, and being one of the first to offer a trending product can help set your brand apart. Just make sure you stock up on enough ingredients and have enough staff on hand so that you can handle long queues.Source: Froth Coffee Lisburn (Instagram Reels)Trends come and go, but smart social media moves fast.
