October 2025 social media calendar
Editor’s Note:
Hi, I’m Layla, content producer here at Dotdigital and your go-to for helping you plan your social media calendar. Between autumn aesthetics, Halloween campaigns, and that subtle shift toward the holiday season, it’s one of the most exciting times to experiment with your content.
This month, focus on storytelling that feels relatable. Think:
- Behind-the-scenes clips showing how your brand is prepping for the season.
- “Day-in-the-life” content with a fall twist.
- or quick how-tos that tie into autumn trends like styling cozy outfits, making warm recipes, or curating your perfect Halloween night in.
- You can even try “expectation vs. reality” or “POV” videos that add humor and personality to your feed.
Short-form content is still your best bet for reach, but make sure it feels natural and fun not overly polished. Use trending sounds that fit your brand’s vibe, show real people, and lean into seasonal aesthetics like rich colors, texture, and cozy details.
October sets the stage for fresh content opportunities, helping you boost engagement and add a autumnal twist to your strategy.
This guide highlights key themes and observances to help you plan your October social media calendar. It’s packed with ideas to spark inspiration for both your social posts and email marketing campaigns.
