Compelling captions have the power to increase your account’s engagement and reach, drive website traffic, add leads to your funnel, and strengthen your brand.

How to write creative and engaging captions

The best social media copy inspires readers to engage further, driving them to read your Instagram bio, hit the follow button, or share the post with a friend. They may even visit your website, read your blog, or sign up for your email newsletter.

Include the following caption elements to encourage engagement and maximize each social post’s performance.

Keep brand voice consistent

Pick a tone of voice that accurately reflects your brand and maintain it across all social accounts and captions. Good captions display some personality, showing followers you aren’t identical to every other company in your industry.

Offer value

Cut through the noise on Instagram, Facebook, and Twitter by offering your audience something of value, like a special offer, free resources, or information they'll find useful.

Start strong

Most people won’t read your entire caption, so start with the most compelling information. Since Instagram limits the characters displayed in the feed, your caption must command attention from the first word.

Craft a narrative

Bring your company, products, and services to life by sharing a story or deeper meaning. The perfect captions are sincere, relatable, and evoke emotion. Captivate your audience so they want to learn more.

Include a call to action

Always provide a next step for readers — whether it’s to comment below, sign up for your newsletter, or take advantage of a promotion. Give them a straightforward way to take action, and you're more likely to gain followers, shares, and even website visits.

It's generally recommended to post to your Instagram feed at least 2-3 times each week, and up to once per day. Start by establishing a regular cadence, even if that means you only post once per week. Over time, you'll figure out how often your audience wants to hear from you. Don't forget to post on Instagram Stories, too — 500 million people use Stories daily!

If you don't have time to publish every day, you can pre-schedule posts in bulk using social media tools like Sprout Social, HubSpot, Buffer, or Hootsuite.

There's no quick fix to make your Instagram engagement explode, but there are proven techniques to improve yours without paying for likes and followers:

  • Use the right hashtags
  • Determine when your audience is online and schedule posts accordingly
  • Make sure the visual aspect of your post is just as strong, if not stronger, than your caption. Instagram is a very visual platform, and you need to catch someone's eye with a well-composed image or video to convince them to read more.
  • Sometimes the Instagram algorithm won't surface your posts to your followers' feed, so also share them on your Instagram Story for improved visibility
  • Interact genuinely with other accounts
  • Audit your competitors to discover what works well for them, then adjust your strategy

While the Instagram captions interface allows for 2,200 characters, short captions tend to perform better. According to Social Report, your Instagram posts will perform best when limited to 138-150 characters. Since most people quickly scroll through Instagram, they’re unlikely to read the entire caption unless the post grabs their interest immediately.
