5 Content Marketing Ideas for September 2026

September 2026 offers ecommerce content marketers an array of topic opportunities, including Back to Hogwarts Day, bacon, emergency preparedness, Grandparents Day, and fall home resets.

Content marketing is the creation, publication, and promotion of articles, videos, podcasts, and similar content to attract, engage, and retain customers. It works on the principle of reciprocity. When a merchant provides helpful, informative, or entertaining content, shoppers are relatively more likely to respond with attention, trust, and purchases.

Here are five content marketing ideas you can try in September 2026.

Back to Hogwarts Day

September 1 is Back to Hogwarts Day. It marks the fictional day when students board the Hogwarts Express and return to school.

In the “Harry Potter” stories, Hogwarts School of Witchcraft and Wizardry is a hidden boarding school in Scotland. Each September 1, students return for the new term, boarding the Hogwarts Express at London’s King’s Cross Station from the fictional Platform 9 3/4 and traveling north toward the castle.

The official Wizarding World site calls this pseudo-holiday a worldwide fan celebration and a season for announcements, experiences, and retail activity.

While content marketers will need to be careful — Harry Potter, Hogwarts, house names, characters, and related marks are intellectual property — there are still ways to anchor around the date.

For example, content could focus on:

• School-year rituals,
• Fantasy reading,
• Dorm life,
• Potter-inspired fall style,
• Board games or puzzles,
• Movie nights,
• Party supplies or costumes,
• Home decor.

The goal is to borrow the energy around September 1 without borrowing protected names, symbols, or designs, unless, of course, the merchant carries Harry Potter items.

International Bacon Day

Bacon is not only for breakfast.

September 5, 2026, is International Bacon Day and a content marketer’s opportunity to pay homage to what might be America’s favorite food.

Various published reports estimate that a typical American will consume about 18 pounds of bacon annually. And nearly 20% of folks in the United States would not want to go without it.

The only question then is how to integrate bacon content in a way that is helpful, informative, or entertaining for shoppers and still associated with the products a content marketer is ultimately promoting. The answer is to look for the intersection of the products a shop sells and bacon.

For example, imagine a men’s clothing store. The overlap between polo shirts and America’s favorite breakfast meat could be greasy stains. Thus, the shop content marketer could publish a listicle on bacon grease-resistant fabrics or a bacon stain-removal guide.

National Preparedness Month

National Preparedness Month is an opportunity to publish checklists and listicles.

September is National Preparedness Month, an annual reminder for Americans to prepare for disasters and emergencies at home, work, and in their communities.

Preparedness content works because it is useful before it is urgent. A family will not want to think about power outages, wildfires, hurricanes, floods, winter storms, or a roadside breakdown after the event has started. It will need a plan, a checklist, and the supplies to carry both out.

For ecommerce content marketers, the idea is to publish preparation listicles focused on the items a store sells. An automotive retailer, for example, could publish a car emergency kit checklist. A hardware store could focus on power outages. A pet supply shop could help owners prepare dogs and cats for an evacuation.

Here are a few more examples.

• Hardware store: “How to Build a  24-hour Power Outage Survival Kit”
• Outdoor retailer: “Camping Gear That Belongs in an Emergency Kit”
• Home goods store: “How to Store Water, Batteries, and Important Documents”

Aim to answer the question “What should I have ready before I need it?”

Grandparents Day

Once a year is not enough time to celebrate the value of our grandparents.

National Grandparents Day falls on the first Sunday after Labor Day in September, which in 2026 is the 13th.

The holiday can certainly be a gift-giving occasion, but that may not be the best angle for content marketing. Grandparents Day can be about memory, tradition, and the skills one generation passes to the next. For ecommerce content marketers, the idea is to publish how-to content around things grandparents know how to do.

Imagine, for instance, an online kitchen store. Its content team might publish “5 Things Grandma Knew About Cast Iron,” covering seasoning, cleaning, storage, heat control, and simple recipes. The article would be useful, nostalgic, and closely connected to the store’s products.

The same approach could work for many merchants.

• Garden shop: “What Grandparents Know about Saving Seeds”
• Sporting goods retailer: “How Grandpa Packed a Tackle Box”
• Craft retailer: “The Sewing Skills Worth Teaching Again”
• Hardware store: “Grandpa’s Fixes Every Homeowner Should Know”
• Home goods boutique: “How Nona Set a Table for Sunday Dinner”

Fall Home Reset

September is a good time to get the house in order for fall.

September is when many households start moving back indoors. Even before the weather turns cold, shorter days, school schedules, football weekends, and earlier dinners can change how folks use their homes.

That shift creates a content opportunity for ecommerce marketers selling home goods, cleaning supplies, and similar items. Here, the idea is to publish content that helps shoppers reset their homes for fall.

Here are a few example titles.

• Lighting store: “How to Brighten a Room Before the Days Get Short”
• Bedding retailer: “The First Cold Night Bedroom Checklist”
• Kitchen store: “How to Set Up a Fall Baking Station”
• Storage shop: “What to Put Away When Summer Ends”
• Furniture store: “How to Make the Living Room Ready for Football Season”

This sort of content works because it is practical and seasonal.
