Did you know that poorly written or missing image alt text can damage your SEO rankings and expose you to accessibility violations?

In this post, we'll show you how to use the AltText.ai WordPress plugin to bulk-scan and fix all your site's images—without needing to edit each one manually. Whether you're optimizing an eCommerce store, a content-heavy blog, or a portfolio site, this simple tool helps you stay compliant and drive more traffic in record time.

Why alt text still matters in 2025

Alt text (alternative text) is the hidden description attached to an image, often used by screen readers to describe visuals for visually impaired users. But alt text has expanded far beyond accessibility—it now plays a critical role in how Google and other search engines understand and rank your content.

Why it matters for SEO

Google uses alt text to understand what your images are about. When you include descriptive and keyword-rich alt text, your images are more likely to appear in image search results—adding another channel to drive traffic to your site. Without it, you're leaving potential impressions and clicks on the table.

Why it matters for accessibility

Globally, over 2.2 billion people experience vision impairment. Alt text allows them to access your content through screen readers. Inaccessible websites can face legal risks under ADA or WCAG regulations—especially for public-facing businesses.

Why most WordPress sites fall short

Despite plugins and themes that support alt text fields, most WordPress users never fill them in. Why? Because manually writing hundreds (or thousands) of alt tags is slow, boring, and hard to scale.

How to bulk fix alt text with AltText.ai's WordPress plugin

The AltText.ai WordPress plugin eliminates the bottlenecks of manual image editing by allowing you to generate alt text in bulk—accurately, automatically, and intelligently.

Here's how it works:

Step-by-step setup

1. Install the AltText.ai plugin from the WordPress marketplace
2. Connect your API key from your AltText.ai dashboard
3. Scan your media library to find missing or outdated alt attributes
4. Generate high-quality, descriptive alt text in bulk
5. Review & Approve alt text before publishing (optional)
6. Sync your updated alt text across your site instantly

Customize your alt text style for SEO or brand voice

Not all alt text is created equal.

With AltText.ai, you can customize the tone, length, and structure of your alt text output. This is especially helpful for brands looking to:

• Match brand voice ("Modern," "Playful," "Professional")
• Target SEO keywords automatically
• Exclude branded or decorative content
• Localize for multilingual audiences

Why this matters

Most alt text generators give you generic results. AltText.ai lets you define how you want your alt text written—turning accessibility metadata into a growth channel.

See bulk results instantly — no manual edits required

Imagine fixing 500 missing alt attributes in 5 minutes. With bulk generation, you can scan, update, and push new alt text across your entire site or selected posts—all at once.

Why this matters

Updating alt text manually requires:

• Finding every image in your media library
• Opening each post or product
• Writing a unique, descriptive caption
• Saving and updating your live site

That's hours (or days) of work. With AltText.ai's bulk generator, this becomes a 5-minute task.

Use cases: who this is perfect for

If you manage content at scale, this tool was built for you.

Ideal for:

• eCommerce sites with large product galleries
• Bloggers & publishers with media-rich articles
• Agencies managing accessibility for multiple clients
• SEO managers optimizing image search and page relevance
• Marketing teams looking to automate tedious tasks
