Alt Text & Image SEO — ALTification

ALTification is a WordPress plugin designed to generate AI-powered, keyword-aware alt text, captions, and descriptions for images, with a focus on improving SEO and accessibility. It uses the focus keyphrase and page context from a site's SEO plugin to create contextual image metadata. The tool is intended for WordPress site owners and administrators seeking to automate and enhance image optimization for both search engines and accessibility standards.

Among its features, ALTification offers a Site Scan function that enables bulk generation of alt text across an entire website, including SEO gap detection to identify images where alt text does not match the page keyword. It supports page-level generation and integrates with several SEO plugins, specifically reading focus keyphrases from Yoast SEO, Rank Math, AIOSEO, SEOPress, and The SEO Framework. For WooCommerce users, the plugin can generate alt text for product images using product keywords and category context. It also provides the ability to generate captions and descriptions alongside alt text in a single request.

The plugin includes support for marking images as decorative to suppress alt text, aligning with WCAG compliance. It can automatically scan Advanced Custom Fields (ACF) image fields. After running a bulk scan, users can download a before-and-after CSV report that documents changes made to every image, which can be shared with clients.

ALTification is delivered as a free plugin available from the WordPress plugin directory. Activation requires an API key from the ALTification platform, and all AI generation occurs on the ALTification servers—users do not need accounts with external AI providers. The service offers 25 free credits upon account creation, with no credit card required to get started. This positions ALTification as a specialized solution for automating image metadata generation within the WordPress ecosystem.
