Alternative text, or alt-text, is simply a line added to the code of a website that describes the appearance and function of an associated image. If you’ve ever performed an image search on a search engine like Bing or Google and wondered how the search algorithm brings up pictures based on your query, alt-text is one of the more basic ways it does this.
There are a number of benefits to providing alt-text to images on your webpage. If you’re looking to learn how to do it properly and write useful descriptions, understanding these benefits is a great place to start.
Why should you add alt-text to images on your website?
From a basic functional standpoint, it is not critical to add alt-text to your images. However, there are some key advantages from both a user experience and SEO perspective for doing so. These include:
- If an image does not load properly, alt-text will be displayed as a backup
- Alt-text can help visually impaired users who use screen readers better understand on-screen imagery
- It can provide image context for search crawlers and help your rankings in both web and image searches
As you write alt-text image descriptions, it’s important to keep these primary uses and benefits in mind to ensure they achieve their objectives.

Additionally, many programs such as photo viewers, photo editors and content management systems allow you to add alt-text to images through a more user-friendly interface. Check with your webmaster to determine the optimal method for adding alt-text to your images.
In terms of writing a quality description, avoid overly long descriptions and keyword stuffing — although keywords should be utilized mindfully. Instead, imagine closing your eyes and having someone read the description to you. If you see something close to the image in your head, this means it’s a good alt-text description.
