Alt-text is like a caption, only it’s built into your images rather than written beneath them. They’re typically used to make content accessible for visually impaired users but can also be used for SEO. You don’t need special software or skills to write alt-text. Here’s a quick guide on how to write SEO-friendly alt-text for your images:

Before you can start typing SEO-friendly alt-text for your images, you will need to find SEO-friendly images for your content. Make sure the images are legally yours to use and relevant to the content you’re creating. Google will take note of images that are irrelevant or unsightly and mark them as spam, dipping your SEO ranking lower.
