Built specifically for online stores. Product Image SEO scans your
entire product catalog, generates accurate AI-powered alt text for every
product image using your product titles, categories, attributes, and SKUs
as context, and helps your products rank in Google Image Search.

Unlike generic alt text plugins, Product Image SEO understands product
data. It treats variation images, gallery images, and featured images
differently. It uses your product attributes as context. It gives you a
product-by-product catalog dashboard with SKUs, prices, and quality scores.
And it exports a full image SEO audit report for your entire store.

Why product image SEO matters

Google Image Search is a major source of buyer-intent traffic for online
stores. But Google cannot
“see” your images — it reads alt text to understand what each image shows.
Poorly written or missing alt text means your products are invisible to
image search, invisible to Google Shopping, and increasingly invisible to
AI shopping assistants like ChatGPT and Perplexity.

Product Image SEO fixes this at scale.

Requires Alt Audit API

This plugin connects to the Alt Audit service at altaudit.com. The plugin
itself is free and open source. Alt text generation uses credits from your
Alt Audit account:

Free plan: 25 credits/month forever (no credit card)
Pro plan: 1,000 credits/month
Agency plan: 5,000 credits/month

One credit processes one product image. Sign up at altaudit.com.

purpose Alt Audit plugin instead.
Both plugins share the same Alt Audit account.

External services

This plugin connects to the Alt Audit API (https://altaudit.com/api/v1) to
generate AI alt text for product images. This service is required for the
plugin’s core functionality.

What is sent and when:
– When a user clicks “Generate Alt Text” on a product, the plugin sends
the product image URL, product title, category path, attributes, SKU,
and short description to the Alt Audit API.
– When a user runs a bulk generation job from the Bulk Fix or Catalog
screens, the plugin sends the same product data for each selected
product to the Alt Audit API.
– When the “Auto-generate on save” setting is enabled in the plugin
settings, the plugin also sends product data to the Alt Audit API
automatically each time a product is saved or updated in WooCommerce
(whether via the admin UI, REST API, CSV import, or programmatic save).
This setting is disabled by default — no data is sent automatically
unless the user explicitly enables it.
– No data is sent on plugin activation, deactivation, or during normal
browsing.
– The API key is sent with each request to authenticate the account.

Data handling:
– Alt Audit does not store uploaded product images on its servers.
– Only the generated alt text and usage metadata are retained.
– Privacy policy: https://altaudit.com/privacy-policy
– Terms of service: https://altaudit.com/terms-of-service
