Alt Text & Image SEO — ALTification

Alt Text & Image SEO — ALTification

By Rob Skinn
Download

Description

ALTification uses AI to generate keyword-aware alt text, captions, and descriptions for your images — directly from your SEO plugin’s focus keyphrase and page context.

Features:

  • Bulk generate alt text across your entire site with the Site Scan
  • Page-level generation with keyword context from Yoast SEO, Rank Math, AIOSEO, SEOPress, and The SEO Framework
  • Generate captions and descriptions alongside alt text
  • Media Library column showing SEO health badges for every image
  • Post editor metabox for inline generation
  • Detect and fix SEO gaps where alt text doesn’t reflect the page keyword
  • Mark decorative images to suppress alt text (WCAG compliant)
  • Supports WooCommerce products, ACF image fields and shared images
  • Before & After report for agency workflows (Agency plan)

ALTification connects to the ALTification platform API to generate content. An API key is required.

External Services

This plugin sends data to the ALTification API and Anthropic (Claude) when you trigger a generation, scan, or credit check — never automatically in the background.

ALTification API

Endpoint: https://altification.ai/wp-json/altification/v1/

When you generate, the plugin sends:

  • Your image (as a URL or base64-encoded data)
  • The page’s SEO context (focus keyword, meta title, meta description, where available from your SEO plugin)
  • Your site’s context (site name, language, WooCommerce product/category data if relevant, a short excerpt of your homepage text, ACF field content if you have configured ACF support)
  • A non-identifying site fingerprint (an MD5 hash of WordPress’s COOKIEHASH and site URL, used to lock your API key to one site)
  • Your ALTification API key

The API returns the generated text, your remaining credit balance and your account status.

ALTification does not store the image after the response is returned.

Anthropic (Claude)

ALTification’s server uses Anthropic’s Claude API to produce generated text. The plugin does not call Anthropic directly — no Anthropic account or key is needed.

  • Anthropic Commercial Terms: https://www.anthropic.com/legal/commercial-terms

Use of this plugin requires an ALTification account and API key, available at https://altification.ai.

FAQ

Do I need an API key?

Yes. You only need an ALTification API key — get yours from altification.ai/dashboard. You do not need to manage your own Anthropic or other AI provider key; generation is handled on the ALTification server. See the External Services section below for details on how data is processed.

Which SEO plugins are supported for keyword context?

Yoast SEO, Rank Math, All in One SEO, SEOPress, and The SEO Framework are all supported. The focus keyphrase is read automatically when you load a page in the scanner.

Can I generate alt text for WooCommerce products?

Yes. Product images use the product’s focus keyword and the WooCommerce product context is included in the prompt.

Does it support ACF image fields?

Yes. ALTification scans for ACF image fields and prompts you to add any newly discovered fields to your settings.

Is the generated alt text saved automatically?

Optionally. You can enable “Save on generation” in the Site Scan to save automatically, or review and save manually.
