If you own a website or blog, you may have heard about alt text, but do you know what it is? Alt text is a brief description of an image that appears when the image cannot be displayed. It is a crucial element in web design and SEO, yet many website owners ignore it. In this article, we’ll explore ten powerful reasons why you need alt text for images on your website.

What is Alt Text?

Alt text, also known as “alt attributes” or “alt descriptions,” is a piece of HTML code used to describe the content of an image on a website. When an image fails to load, alt text appears in its place, allowing visually impaired users to understand the image’s context.
  1. Accessibility

Alt text is essential for making your website accessible to everyone, including people with visual impairments. If your images lack alt text, these individuals will not be able to perceive the content of your website. By adding alt text, you make your website more inclusive and accessible to everyone.
  1. SEO

Alt text plays a crucial role in search engine optimization (SEO). Search engines like Google and Bing use alt text to understand the content of images on your website. When search engines index your site, they also index the alt text associated with your images. This can help your website rank higher in search engine results pages (SERPs) and attract more organic traffic.
  1. Better User Experience

Adding alt text to your images improves the user experience on your website. When an image fails to load, the alt text appears in its place, providing users with context and information about the image. This can help keep visitors engaged and prevent them from leaving your site.
  1. Compliance with Web Standards

Alt text is a fundamental element of web design and adheres to web standards. If your website doesn’t include alt text, it may not comply with web design best practices and accessibility guidelines. This can result in a poor user experience and legal issues.
  1. Increased Click-Through Rates

When alt text is used correctly, it can increase click-through rates. If your image’s alt text accurately describes its content, users are more likely to click on it, increasing engagement on your website.
  1. Improved Website Load Time

When images lack alt text, it takes longer for web pages to load. This can negatively impact your website’s load time, which is a crucial factor in user experience and SEO. By including alt text, you can improve your website’s load time and increase user satisfaction.
  1. Social Media Sharing

When someone shares your content on social media platforms like Twitter or Facebook, the alt text associated with your images is used as the image’s description. This can increase the visibility of your content and drive more traffic to your website.
  1. Increased Trust and Credibility

Adding alt text to your images can increase trust and credibility with your audience. By providing context and information about your images, you establish yourself as a trustworthy and reliable source of information.
  1. Compliance with Legal Regulations

Alt text is required by law for websites that must comply with accessibility guidelines, such as the Americans with Disabilities Act (ADA). Failing to include alt text can result in legal action and fines.
  1. Competitive Advantage

By including alt text on your website, you gain a competitive advantage over websites that ignore it. By adhering to web standards and accessibility guidelines, you demonstrate your commitment to providing the best user experience possible.


Alt text is a vital element of web design and SEO. It improves website accessibility, user experience, compliance with web standards, and legal regulations. Additionally, it can increase click-through rates, social media sharing, trust, credibility, and competitive advantage.
