What is the Instagram Alt Text?

It’s the visual description of your picture for visually-impaired users.

Generally this description is read aloud by screen reading software programmes.

If the image has no alt text, Instagram adds its own by using object recognition technology.

Why is the Instagram Alt Text Important?

The Instagram alt text tell Instagram what your picture is about and can help the algorithm better rank your picture and show it more easily to people looking for it.

Although Instagram object recognition technology fills out the void of an empty alt text field, it’s generally considered best practice to add your own alt tag.

Instagram Alt Text Best Practices

Some best practices for optimising the alt text of your posts are:

  1. Use Keywords – Add keywords to your alt text but don’t overdo it
  2. Write Who is in the Picture – This applies to both personal and business Instagram profiles
  3. Write Out the Text in the Picture – This is especially true for important texts defining the purpose of your picture
  4. Don’t forget colours – Make sure you describe the colour of any important element in the photo
