In September 2025, ecommerce content marketers will find inspiration in holidays, both serious and quirky.
Content such as articles and videos can build a relationship with shoppers and keep folks visiting a business’s website. Content drives visibility in generative AI platforms and organic search and fuels social media and email marketing.
The content challenge, however, is generating new topics and material.
What follows are five content marketing ideas your business can use in September 2025.
Labor Day
Labor Day signals seasonal change, creating content marketing opportunities.
Celebrated in the U.S. on the first Monday of September, Labor Day has its roots in the 19th-century workers’ movement, when unions fought for higher wages, better working conditions, and shorter work days at the peak of the Industrial Revolution.
While it retains some of its workers’ pride, the holiday now represents the unofficial end of summer and an occasion for grilling, parades, and Autumn preparation.
It’s a major retail event, too.
Taken together, the day’s history, emphasis on seasonal change, and revenue value make it an exceptional marketing opportunity.
Here are some example article or video titles.
- “Ultimate Guide to Hosting a Last-Minute Labor Day BBQ” could list products such as grilling accessories, BBQ rubs, and similar.
- “How to Dress for Labor Day 2025” would feature inspiration styles and the option to “buy the look.”
- “Get Your Home Ready for the Fall” could leverage the season’s “fresh start,” offering tips on decluttering, organizing, or swapping out decor.
Classical Music Month
Classical Music Month provides ideas beyond music and instruments.
President Bill Clinton established Classical Music Month in 1994.
“Classical music is a celebration of artistic excellence. It spans centuries and generations, delighting and inspiring listeners of all ages. During Classical Music Month, we recognize the many talented composers, conductors, and musicians who bring classical music to our ears and enrich our lives,” wrote Clinton in his official proclamation.
Classical Music Month is an obvious marketing opportunity for music stores, but plenty of other retailers could benefit. Here are example titles:
- A kitchen or party supplier: “The Perfect Classical Music Playlist for a Relaxing Evening”
- A formal wear shop: “What to Wear to the Symphony This Fall”
- Niche memorabilia store: “The 10 Greatest Classical Movie Themes”
National Read a Book Day
Reading is a pastime and a marketing opportunity.
According to various “national day” websites, September 6, 2025, is National Read a Book Day. It’s hardly an official holiday, but there are plenty of opportunities to create blog posts, long-form articles, videos, or podcasts aimed at bibliophiles.
Marketers can frame National Read a Book Day not to sell books, but rather a holiday celebrating quiet, comfort, and imagination. This approach opens up myriad content options.
Here are some example article or video titles.
- “19 Gift Ideas for Readers Who Already Own Too Many Books”
- “How to Create the Ultimate Reading Nook at Home”
- “Evening Reading Routines That Make You Sleep Better”
National Salami Day
National Salami Day is ripe with content marketing flavor.
There is no doubt that September 7th’s National Salami Day is a playful observance, meant to bring a little laughter and food to its celebrants.
Merchants selling items such as charcuterie boards, knives, specialty foods, cheese, wine, or picnic accessories will likely have the most success with salami articles, videos, and podcasts. But folks in other industries can attract readers and viewers, too.
Consider that Newsweek addressed National Salami Day, and t-shirt shop Redbuddle has several salami-themed products.
