Alt Text in Microsoft Word and Google Docs

Alternative text (also known as “alt text,” “alt tags,” or “alt descriptions”) is text that appears in place of an image on a website if it fails to load (or if you hover the cursor over it). It also has two more key uses:

  • Search engines check alt text for keywords, so it can boost SEO.
  • Screen reader tools use it to describe images for visually impaired users.

Alt text is therefore crucial for websites. But it’s also vital if you’re using images or charts in a document and you want it to be accessible.

What should you use as alt text for images, though? And how can you add alt text in Microsoft Word and Google Docs? Let’s take a look.

Adding Alt Text to an Image

The simple answer is to describe what it depicts in relation to the surrounding text. But there are a few other considerations to keep in mind:

  • Be specific rather than generic (e.g., “A parrot” may describe the image, but “A blue and gold macaw extending its right wing” tells us far more).
  • Screen readers can identify visuals in a document, so there is no need to start with “A picture of…” or other redundant phrases.
  • Keep it succinct (ideally, no more than around 125 characters).

In addition, some images may already have alt text, especially if you downloaded them from the internet. As such, it’s wise to check the alt text on an image, and amend it as required, before using it in your content.

In some versions of Microsoft Word, you can also mark an image as decorative if it is not important for the meaning of a document. This will tell screen readers to skip over it, letting them focus on the most relevant text.
