Apply alt text as WordPress renders a page

Bialty Pro adds alt text to images in the rendered frontend HTML using information already available in WordPress. The selected rule can fill missing alt text or replace existing frontend values. Generated text is not saved to the database, so disabling the add-on removes the injected values and leaves Media Library metadata unchanged.

Choose the context for each rule

Rules can draw on focus keywords from Yoast SEO or Rank Math, target keywords from SEOPress, and primary keyphrases from All in One SEO (AIOSEO). Other sources include post or product titles, cleaned image filenames, combinations such as a keyword with a title, and manual alt text set for individual posts, pages, or products.

These rules can standardize alt text across a site. For an image that needs wording specific to its content or accessibility context, a manual override includes more precise control.

Extend coverage to store and custom content

The Pro edition applies the process to custom post types and WooCommerce content, including product pages, product galleries, and related product areas. Product-level manual overrides let you set text for an individual product. Pro also includes blacklist and exclusion rules, broader rule combinations, and an option to add the site title.

Understand where processing applies

Bialty Pro processes local WordPress context at frontend render time. It does not visually analyze images, generate captions with computer vision, call external APIs, execute bulk rewrite jobs, or permanently write generated values to the database. Its performance impact depends on the theme, builder, caching, and page complexity.

It works when content passes through the standard WordPress frontend rendering flow. Documented editors and builders include Gutenberg, the Classic Editor with TinyMCE, Elementor, and SiteOrigin Page Builder. Images in headers, footers, sidebars, or widgets are outside the default scope, and images may be missed when a template or builder bypasses the supported flow. Bialty is disabled in Beaver Builder edit mode to avoid conflicts.

Configure a rule and check the frontend

After activation, select the content types to cover and select rules for missing or existing alt text. Configure WooCommerce, custom post type, exclusion, and manual override options as needed. Then open the published page, clear active cache layers, and inspect the image element's alt attribute in the rendered HTML. The editor view and Media Library field may remain empty or unchanged because Bialty Pro applies values on the frontend.
