Use Short Captions
People use social media to get quick information and fast access to stories.
They intend to achieve that with as little reading as possible. A large
percentage of people who use social media do not have large attention spans.
Instagram is one of the platforms where people do not want to read as much.
Hence, in addition to just keeping the text in your images at minimum, it is
also advisable that your captions are short as possible. A 40-character post is
permissible for Facebook. Captions used on Instagram should not be longer
than this either.
Include a Call to Action
Usually, Instagram does not allow the addition of a clickable CTA to posts
that are not ads. It is only on your Instagram profile that you can include one.
This is a disadvantage.
Beyond creating more recognition for your brand, you should also be
concerned about returns from your ads in terms of purchases and lead
creation. Rather than the usual "link in bio" mention, you can include CTAs
to your ads on Instagram.
