A lot of people are adding alt text incorrectly because it’s a two stage process. It can seem like you’ve added your alt text correctly but it’s actually not working.
Alt text is important because it’s a description that search engines such as Google can use to understand what an image is about. It’s also useful for vision impaired people that are using your website.
This means it’s helpful for SEO. You can use some of your keywords in your alt text but don’t get stupid about it. It should be a natural, clear and accurate description of the image.
This video walks you through how to get your alt text working and how to test to make sure it’s working.
