Addressing the Alt Text Problem in WordPress Websites

In the digital age, ensuring a seamless user experience is crucial, and this includes catering to users with disabilities. One aspect that often gets overlooked is the use of alt text in WordPress websites. This article discusses the challenges surrounding alt text, its impact on accessibility, and potential solutions for WordPress users in North East India and beyond.

The Current State of Alt Text in WordPress

WordPress technically supports alt text, but in real-world scenarios, it often falls short. Common issues include empty alt attributes, filenames being used as alt text, and copied titles with little semantic value. At scale, these oversights can lead to accessibility audits failing, Lighthouse scores dropping, and poor image SEO, resulting in minimal traffic.

Automating Alt Text: A Necessary Step

Manually fixing hundreds of images is not feasible, which brings us to the question: Can alt text be automated safely? The answer is yes, but with certain constraints.

Option 1: REST API

WordPress exposes alt text through the media endpoint, which is reliable for bulk migrations, headless setups, and external tooling. However, it doesn't help generate meaningful descriptions.

Option 2: Custom Media Fields

Adding a custom alt field can improve editor behavior, but it doesn't address the issue of editors still skipping it.

Option 3: AI-Generated Alt Text

AI can generate alt text quickly, but it is not context-aware by default. Common failures include wrong object detection, hallucinated details, incorrect assumptions about people, and repeating generic phrases. Fully automatic replacement is dangerous due to these issues.

A Safer Approach to Alt Text Automation

A more effective approach is to scan the media library, detect missing or low-quality alt text, generate suggestions (not overwrite), preserve existing good alt text, and allow selective application. Automation should assist, not silently replace.

Why Alt Text Matters Now

Alt text affects more than just SEO. It plays a crucial role in Web Content Accessibility Guidelines (WCAG) compliance, accessibility lawsuits, Core Web Vitals audits, and image discoverability. Ignoring it can lead to expensive consequences.

The Future of Alt Text Management in WordPress

To tackle the alt text problem, I am working on a tool called Alt Audit, designed specifically for this workflow. It will scan the WordPress media library, detect missing alt text, generate AI-suggested alt text, and give developers full control over the process, ensuring no blind automation or destructive updates.

Remember, alt text is infrastructure for accessibility. If it's automated without guardrails, it breaks silently. By addressing the alt text problem, we can ensure a more inclusive and accessible web experience for all users.
