September Social Media Ideas in That Get Engagement

When creating social media content, it’s essential to create content that will serve your audience and generate engagement. 

Engagement includes comments, likes, shares, and views of your content, and it’s the key to your success on social media. 

Engagement lets you know what type of content your audience likes, and it also tells the algorithm that your content is valuable and should be shown more often. 

So how do you get more engagement on social media? 

The short answer is…

  • Share an image or video with every post 
  • Ask questions 
  • Use hashtags 
  • Share inspiring content 
  • Celebrate holidays

For the long answer with detailed examples and statistics, read my blog post: 5 Ways to Increase Social Media Engagement. 

Now that you know five simple ways to get more engagement, let’s walk through the social media content ideas for September. 

What to Post on Social Media in September

When planning out your content for the entire month, the first thing you want to do is open your favorite calendar tool and start building your content plan for the month.  

You could use Google Calendar, Asana, Trello, or an old-school paper calendar and a pen. 

Once your calendar is open, you want to identify holidays, local events, business milestones, and special promotions for the month and add them to the calendar.

Holidays to Celebrate on Social Media in September

September is full of holidays and opportunities to run a sale or hold a special promotion.

Depending on the nature of your business and what fits your brand’s core values, you could run a sale in honor of the end of summer, the start of school, National Watermelon Day, or International Beer Day.

For example, if you’re a fitness trainer, you could provide fitness classes for 20% off when the kids go back to school.

If you’re a barber, in honor of world beard day you could offer a free beard trimming with any haircut in September. 

For Positive Thinking Day & or Self Improvement Month, to help raise awareness, you could share self-improvement tips or an inspirational quote on social media. 

If you want to get really crazy, buy your kid(s) that video game they have been begging for on National Video Games Day and share a post/photo on your social channels with the hashtag #nationalvideogamesday.

Restaurants could offer 10% off in celebration of International Chocolate Day, National Linguine Day, National Lobster Day, National Cheeseburger Day, or National Salami Day. 

Whatever holiday or promotion you decide to run, be sure to include it in your content calendar so you can plan your September social media posts.

When people think of September, they typically think of family vacations, summer, and back-to-school season. While there are no major holidays in September, there are plenty of fun observances to celebrate on social media.

Did you know that there are over 235 special holidays and observances in September?

Here are some of the more popular holidays and observances in September: 

September 2: National Lazy Mom’s Day

September 5: Labor Day

September 10: World Suicide Prevention Day

September 11: National Grandparent’s Day 

September 22: First Day of Fall 

September 25: Daughter’s Day 

September 29: National Coffee Day 

Self-Care Awareness Month 

For the complete list of September holidays, visit: September Holidays to Celebrate on Social Media.

Inside the complete list of holidays, take a look at the daily observancesweek-long, or month-long holidays and find some fun ones that spark unique ideas.

For example, share a photo of you engaging in a wellness-promoting activity in honor of National Wellness Month. Share how that activity helps you stay energized and healthy.

For example, share a photo of you and your family doing a fun activity together on National Family Day and share how important your family is to you. 

Or, you could share a photo of you or your employees taking a dance party break on National Dance Day. 

To find fun days to celebrate on social media, use a resource like my Social Media Content Club, which provides a detailed list of more than 3,200 special days and observances to help you plan out the special days you want to recognize during September.

Next, look at your marketing plan to see if you have any big promotions planned for the month. If you’re running a huge holiday sale, add it to your content calendar and plan out which days you want to promote it on social media.

Once all of your special days and promotions are scheduled on your calendar, add 1 – 2 question posts each week throughout the month.

Questions to Ask on Social Media in September

September is associated with back-to-school, fall, Grandparents Day, self-care, NFL football, and Labor Day. It’s also National Wellness Month and contains National Friendship Day and World Lion Day.

Create social media posts asking questions based on those themes.

For example, “What was the best part of summer when you were a kid?” or “Who was your childhood best friend?”

Unless you’re a teacher, asking your followers about their favorite subject in school has nothing to do with your business. 

But guess what? That’s OK! In fact, it’s better than OK. It’s exactly what you want to do. 

Your social media feed should not be full of self-promotional posts that scream “ME, ME, ME!!!”  

Good social media content focuses on creating positive conversations and providing value to your audience. 

Fun questions are a great way to create positive conversations and get more engagement on your posts. 

Remember, engagement lets the algorithm know that your content is valuable and increases its visibility. 

Once you’ve added questions to your content calendar, add 1- 2 positive quotes to share each week.

Quotes to Share on Social Media in September

Quotes focused on fall, Grandparents, labor, September 11th, and self-care are ideal for September. 

For example:

  • “A new school year means new beginnings, new adventures.” Denise Witmer
  • “Grandparents make the world a little softer, a little kinder, a little warmer.” 
  • “No day shall erase you from the memory of time.” -Sandy Dahl

Positive and uplifting quotes make great social media content because they help counteract all the toxicity on social media and generate lots of likes.  

When designing your quote images, I recommend playing with different fonts. Big, bold fonts are easy to read, but scripted fonts are visually appealing and can catch people’s attention.

Test a variety of fonts and see which designs perform the best.

Once you’ve added quotes to your content calendar, fill the remaining days with educational, personal, or promotional posts.

Finalize Your September Content Calendar

Once you’ve added holidays, questions, and quotes to your content calendar, you’re ready to fill in the remaining days.

First, add in one self-promotional post each week.

Remember, your content should focus on serving your audience, but that doesn’t mean you can’t ever promote your business.

The goal with social media is to grow your business, so make sure you’re promoting your products and services about once a week.

Once each day of your September content calendar is planned out, you’re ready to identify popular and trending hashtags to use in your posts. 

Hashtags to Use on Social Media in September

Hashtags are a fantastic way to increase the visibility and reach of your social media posts. 

You can use up to 30 hashtags in your Instagram posts, but research from Track Maven suggests that nine hashtags are the magic number for Instagram.

On Facebook and Twitter, I recommend you use 1 – 2 hashtags, and on LinkedIn, use 3 – 5 hashtags.

When compiling your list of hashtags for Instagram, be careful not to use only the most popular hashtags.

Hashtags with millions of posts are highly competitive, reducing the chance of your content getting seen.

Hashtag Sign

To increase your exposure, I recommend including hashtags with a range of popularity in your posts. 

Choose a few popular hashtags with millions of posts, a few hashtags with hundreds of thousands of posts, and a few less popular hashtags with thousands of posts.  

To help you out, I’ve compiled a list of 20 of the best hashtags to use on Social Media in September: 

  • #americanfootball
  • #autumnday 
  • #autumnvibes
  • #backtoschool
  • #fall2022
  • #grandparentlove
  • #grandparentsday
  • #happyfall
  • #happyseptember
  • #helloseptember
  • #laborday2022
  • #labordayweekend
  • #neverforget911
  • #newschoolyear
  • #nflfootball
  • #patriotday
  • #schooltime
  • #selfcareawareness 
  • #selfcareseptember
  • #september2022

How to Create Content for Social Media

Now that you have your social media content planned out for September, you’ll need to set aside time each week to create your September content ideas. 

Remember when I said to include an image or video in every post? 

Research has shown that posts with an image get 2.3 times more engagement than posts without an image. 

If you’re going to bother creating content, include an image. 

A great tool to use is It’s a free online design tool that takes all the guesswork out of graphic design.

When creating content for social media, I recommend blocking off 2 – 3 hours each week. 

You’ll use that time to plan out your posts for the week, design images or record videos, write the captions, and research all the hashtags for each post.

If you don’t have 2 – 3 hours to spare each week and need a content creation hack, then join the Social Media Content Club and cut that time down to 1 minute a day!
