Bulk Update WordPress Images Alt Text Automatically

If you want better SEO and accessibility, you need to bulk update WordPress images alt text across your entire website. Doing it manually? That’s not sustainable—especially if your site has hundreds or thousands of media files.

This article explains how to automate alt and title attributes using a reliable, structured method. With the help of a powerful WordPress image metadata plugin, you can update all existing image alt text (and title tags) in just a few clicks—no manual editing required.

Why Bulk Updating Images Alt Text Is Essential

Every image on your website should have alt text. It helps:

• Search engines understand the image content
• Improve visibility in Google Images
• Assist users with visual impairments via screen readers
• Ensure compliance with WCAG 2.1

When you bulk update WordPress image alt text, you not only improve SEO but also provide a better, more accessible experience for all users.

Why Manual Metadata Editing Fails at Scale

By default, WordPress lets you set alt and title text per image in the Media Library. But when managing hundreds of posts, pages, or products, this becomes inefficient.

Common problems include:

• Missing alt text for featured images
• Unlabeled inline images
• No metadata on imported or older media
• Inconsistent title formatting
• Time wasted on repetitive edits

If you’re serious about image SEO, bulk updates are the only way forward.

Available Dynamic Tags for Metadata

You can build structured metadata using the following tags:

• {{post_title}} – Title of the post
• {{page_title}} – Page title
• {{site_title}} – Website name
• {{image_name}} – File name of the image
• {{image_caption}} – Caption set in Media Library
• {{image_description}} – Image description
• {{image_alt}} – Existing alt attribute
• {{product_title}} – For WooCommerce (Pro version only)

Example alt template:

CopyEdit{{post_title}} – {{site_title}} 

Output:

cssCopyEditHow to Start a Podcast – PodMaster Blog 

This ensures all alt text is relevant, structured, and tied to actual content.
