Lesson 5: Alt-Tags


Optimizing your images by adding alt-tag’s to your images, helps you to make them more functional and also more searchable! Lets dig into what exactly alt-tag’s are and how to write them,

In this lesson we will:

1. Learn what Alt-Tag’s are
2. How to write Alt-Tag’s
3. How to add Alt-Tag’s to your website

Step 1: What are Alt Tags?

Alt-tag’s are alternative text that will display in place of your image if the link is broken, but are also meant to be accessible to those with visual impairments. So when you write your alt-tags remember that it is not only about the search engine, it’s about making your website more accessible too!

Because alt-tag’s were invented for anyone with a visual impairment, you need to keep in mind that they might be read out loud to someone. For that reason you don’t want to include .jpeg, or .png in that, and you do want your alt-tag to make sense to someone!

In Squarespace, alt-tag’s are (frustratingly) not labelled. Alt-tag’s are essentially just the name of your image, and in Squarespace are named as ‘Filename (Optional)’. They are not optional if you want to help your site with it’s SEO, or if you want your website to be accessible, so don’t skip them!

Step 2: How to write Alt-Tag's

Much like page descriptions, you want your alt-tag’s to be sentences with some keywords if possible. The most important thing to write though, is what’s actually in the image. As these are also used by anyone with a visual impairment, alt-tag’s can be read out loud and you want to ensure that the description of the image is accurate, and that the way you describe the image also makes sense.

Your alt-tag’s should be:

  • sentences

  • descriptive of the image itself

  • include keywords only if it makes sense to do so

  • not include image file types

  • short and to the point


Step 3: How to add Alt-Tag's to your website

Go to Image > Edit > Filename

  • Add the text of your alt-tag into the ‘Filename (Optional)’ section

  • Click ‘Apply’

  • Repeat for all images on your website

  • Don’t forget to do this when adding new images to your website!
