Image alt tags

Marketers know the impact of images. They play a crucial role in engaging website visitors. However, it's equally important to ensure that images are accessible to all users, including search crawlers and those who may rely on assistive technologies. This is where image alt tags, also called image alt text, come into play.

Keep reading to learn understand what image alt tags are, why they are important, and see some examples and tips for optimizing them effectively.

Understanding image alt text

Image alt tags are HTML attributes that provide alternative text descriptions for images. When an image can't load right, the alt text is displayed in place of that image. Additionally, alt tags are read by screen readers to assist those who are visually impaired so they can better understand the content of the image.

Here's why they're important:

  • Accessibility: Alt tags are crucial for web accessibility, making images accessible to individuals who are visually impairments or those who rely on assistive technologies.
  • Benefits: Alt tags also contribute to SEO by providing search engines, like Google and Bing, with context about the image, which can improve your website's visibility and rankings in relevant search results.

Image alt tags tips

Be descriptive

Describe the image accurately and concisely, conveying its content and purpose.

Example: Alt tag for a cat image: "A fluffy gray cat playing with a ball of yarn."

Be relevant

Incorporate relevant keywords into alt tags, but avoid keyword stuffing. Focus on providing meaningful descriptions.

Example: Alt tag for a beach vacation image: "Sunset view at a tropical beach resort in Hawaii."

Don't repeat

If multiple instances of the same image appear on a page, use unique alt text for each instance to provide specific details.

Example: Alt tag for a logo image: "Company Name Logo" (on the homepage) and "Company Name - Contact Us" (on the contact page).

Be unique

Skip phrases like "image of" or "picture of" since it's already implied.

Example: Instead of "Image of a red rose," use "Red rose in full bloom."

Be creative

For purely decorative images that don't convey meaningful information, use empty alt tags or a null alt attribute (alt="") to indicate that they are decorative.

Example: Alt tag for a decorative line separator: ""
