What is Alt Text
For individuals who can’t read or see clearly, alt text is an attribute they depend on when visiting a website. Screen readers use it to translate web copy into audio so individuals can understand what is on the site, from words to images.
Alt text is vital to creating an accessible web for everyone, and this is the reason Google places value on alt text. Sites that take the time to ensure alt text is in place are contributing to that vision. But what exactly is it?
Alt text is descriptive text for images that appear on a website. This text comes into play in a few different situations:
- When an image doesn’t display or load properly
- When a screen reader is in use
- When a user’s mouse hovers over an image
- When an images are blocked
- When search engines crawl a website for content
Alt text is normally hidden to users but it ensures that no information is lost on your website. It’s an easy addition and gives you an opportunity to put yourself in someone else’s shoes when describing images!
Why Does Alt Text Matter
It may seem like an unnecessary component to add to your website, but trust us, it’s not! Alt text matters, especially in regards to making your website accessible.
The primary goal of alt text is to provide individuals with visual impairments or disabilities a better way of understanding what images are on a web page. These individuals depend on alt text being integrated on a website.
When they find themselves on a website that lacks alt text, they are unable to understand what the image is and if it relates to the written content. This can be frustrating and could cause them to leave your website. In some cases, this could even give them grounds to file a complaint, or pursue litigation — an extreme outcome, but a real threat to industries that require Americans With Disabilities (ADA) compliance.
The secondary goal of alt text is benefiting your website’s SEO. It is another opportunity to incorporate keywords in your content. Google takes it into consideration when ranking a site because it helps their bots understand your website better (see comment above about why they take it into account)!
Having alt text on images will help you reach more people, be inclusive, and communicate more effectively with your consumer.
