What is Flance Product Image SEO?
Flance Product Image SEO is a free WordPress plugin for WooCommerce stores that treats image SEO as a catalog problem, not a media-library problem. It scans every featured, gallery and variation image of every product, gives each one a deterministic 0–100 alt text quality score with a plain-English explanation, and generates product-aware AI alt text — using your product titles, categories, attributes and SKUs — so your products become visible in Google Image Search, Google Shopping and AI shopping assistants.
Built for product catalogs
Generic alt text plugins treat every image the same. This one understands WooCommerce: products, variations, galleries, SKUs and attributes.
Catalog-wide audit
One click scans every product image in the store and shows exactly which are missing alt text, which are weak, and where to start.
Product-aware AI
Generation uses the product title, category, attributes and SKU as context — alt text describes the actual product, not just "an image".
Bulk background fixing
Fix hundreds of images in one run with live progress, per-image counters, and automatic skipping of images that are already covered.
Explainable 0–100 scoring
A deterministic quality score for every image — length, descriptiveness, structure, accessibility — always with a plain-English explanation.
Review-first workflow
Every AI suggestion lands in a review modal with a character counter. Accept, edit or regenerate — nothing is saved without you.
Audit reports & CSV export
A score-distribution report for the whole catalog plus a full CSV export — perfect for agencies and client reporting.
From invisible to indexed in three steps
Install next to WooCommerce, connect your free API key, and audit the whole catalog in minutes.

Why not a generic alt text plugin?
Media-library tools don't know what a product is. Catalog SEO needs product context.

Frequently asked questions
Is the plugin really free?
Yes. The plugin is GPL-2.0-or-later and every local feature — auditing, scoring, dashboards, reports, CSV export — is free with no limits. AI generation uses Alt Audit credits: the free plan includes 25 credits per month, no credit card required.
Does it cover product variations and galleries?
Yes. It audits featured images, gallery images and variation images for every product, and variation alt text can use the variation's own attributes (color, size, style).
How is the 0–100 quality score calculated?
Locally and deterministically: length, word count, descriptiveness, keyword structure and accessibility criteria combine into a 0–100 score — and every score ships with a human-readable explanation.
What data does the AI receive?
Only when you generate: the image plus the product title, category, attributes and SKU. Nothing is sent on activation, nothing is sent without your API key, and the service does not store your images.
Will it conflict with my SEO plugin or page builder?
No. It writes to the standard WordPress alt attribute that Yoast, Rank Math, AIOSEO, Elementor, Divi and Gutenberg all read — and it reads focus keywords from your SEO plugin for better AI context.
What happens when I run out of credits?
The plugin keeps working — auditing, manual edits, reports and exports are unaffected. AI generation pauses until your monthly credits reset or you upgrade.
