How To Fix Missing Image Alternative Text (Explained)

As a business owner, it’s crucial to ensure that your multimedia is accessible to all users, including those with visual impairments. One key accessibility component often overlooked is including alternative or “alt text” for images.

What Is Alternative Text

Alternative text, commonly known as alt text, is a descriptive text that provides a concise and clear explanation of an image for people who cannot see it. This description gives the screen reader users a clear understanding of the image’s content and purpose on the webpage. In most browsers, the ALT text is also displayed when an image is broken or disabled.

Examples of Image Alt Text

A picture of a golden retriever: Alt Text = “A golden retriever playing with a frisbee
Logo for Diffuse digital marketing, web design and seo services
A company logo: Alt= “Diffuse Digital Marketing’s logo
A chart illustrating sales growth: Alt= “Line chart showing revenue growth percentages from 2014 to 2020
Tip: Ensure your alt text is concise and accurately reflects the content and purpose of the image. Avoid using phrases like “Image of” or “Picture of.”

Why Is Alternative Text So Important

Accessibility: Alt text ensures that individuals with visual impairments can access and understand images through screen readers.

SEO: Providing descriptive alt text can improve your website’s search engine optimization (SEO), making it easier for search engines to understand your content.

User experience: If an image fails to load, the alt text will be displayed, helping users understand the image context without seeing it. User experience is also a primary ranking factor of SEO, doubling down on the importance of alt text.

Legal compliance: Including alt text is necessary to comply with accessibility guidelines and legislation, such as the Web Content Accessibility Guidelines (WCAG) and the Americans with Disabilities Act (ADA).

What Does Missing Alt Text Mean?

Missing alt text refers to the absence of alternative text (alt text) for an image on a website. Alt text ensures search engines, assistive technologies can understand your content, if the images fail to load, and users who might not be able to see the images on the page.

What Happens If Alt Text Is Missing

  1. Accessibility issues: Visually impaired users who rely on screen readers will miss the information conveyed by that image. It creates a less inclusive browsing experience.
  2. SEO impact: Search engines like Google use alt text to understand the content and context of images. Missing alt text may result in lower rankings for your website in search results.

Usability problems: If an image fails to load due to a slow connection or a broken link, the empty alt attribute won’t provide any helpful information about the picture. Users might need proper context to understand the content.

Conclusion: How to Handle Missing Image Alt Text

To address the issue of missing image alternative text, consider the following:

  1. Review your website or application carefully: Go through each and every image and ensure they have appropriate alternative text provided. This will improve not only web accessibility but also user experience for those who rely on screen readers or have visual impairments.
  2. Use empty alternative text when necessary: If an image is purely decorative and does not contribute to the content, use an empty alternative text attribute (e.g., alt=” “). This allows screen readers to ignore the image, keeping the focus on the main content.
  3. Consider the content and context: When providing alternative text, think about the information the image conveys and how it relates to the surrounding content. Your alt text should be concise and adequately describe the image’s purpose.
  4. Regularly monitor and update your website: As your website or application evolves, new images may be added, or existing ones may change. Keep track of these updates to ensure alternative text remains accurate and relevant to the user experience.

By diligently addressing missing image alt text on your website or application, you help those with visual impairments and create a more accessible and enjoyable experience for all users.
