What is an Alt Tag (Alt Text)?

An alt tag, or alt text (alternative text), is an HTML attribute added to an image tag (<img>) that describes the image's content. It appears in place of the image if the image fails to load, and it's read aloud by screen readers for visually impaired users .

Example: <img src="red-shoes.jpg" alt="Red running shoes on a white background">

Why Are Alt Tags Important for SEO?

Alt tags play a crucial role in both SEO and web accessibility:

  • Image Search Rankings: Google uses alt text to understand what an image is about, which helps it rank in Google Images .
  • Accessibility: Screen readers rely on alt text to describe images to visually impaired users, making your site more inclusive .
  • Context for Crawlers: Search engine bots can't "see" images, so alt text provides essential context.
  • Better User Experience: If an image fails to load, the alt text appears, giving users an idea of what was supposed to be there.
  • Featured Snippets & Voice Search: Well optimized alt text can help your images appear in rich results.

How to Write Good Alt Text

Follow these best practices when creating alt text:

  • Be Descriptive: Describe what's in the image clearly and concisely.
  • Keep it Short: Aim for 5-15 words (under 125 characters).
  • Avoid Keyword Stuffing: Don't cram keywords; use them naturally.
  • Skip "Image of" or "Picture of": Screen readers already announce that it's an image.
  • Include Context: If the image is a product, include the product name and relevant details.
  • Use Empty Alt for Decorative Images: For purely decorative images, use alt="" so screen readers skip them.
