Image SEO — Alt & Title Generator for Magento 2

Auto-generate SEO-optimized alt and title attributes for every product image on your storefront — from configurable templates with tokens ({{name}}, {{sku}}, {{store}}, {{category}}) and filters (truncate, title-case, strip, default, upper, lower). One setting, every image on every theme, every store view.

Panth Image SEO replaces Magento 2's empty or generic image alt/title attributes with fully rendered, merchant-controlled templates. The module runs everywhere images show up — category grids, product galleries, related products, upsells, cross-sells, widgets, search results — so the HTML your shoppers (and search engines) see always includes meaningful, keyword-rich alt text. Compatible with both Hyva and Luma themes, scope-aware (store-view granularity), and tested with Magento sample data.

Template-Based Alt & Title Generation

• Tokens — {{name}}, {{sku}}, {{store}}, {{category}} rendered per image in real time
• Filters — chain |truncate:N, |title, |lower, |upper, |strip, |default:'value' inside any token
• Separate templates — configure alt text and title text independently
• Graceful fallbacks — empty templates fall back to product name so no image ever renders with a blank alt attribute

Store View Aware

• Scope-respecting — every setting is configurable at default / website / store view level
• Multi-language stores — different alt text per store view for localized storefronts
• Multi-brand stores — different brand name in the alt text per website

Complete Surface Coverage

• Product detail page — main gallery image alt + caption + title
• Product gallery — fotorama / Hyva gallery captions with multi-image position suffix (— Image 2 of 5)
• Category grid tiles — alt text on every product card in category listings
• Related / upsell / cross-sell widgets — template applied to every widget image
• Search results — alt text on search result product thumbnails
• CMS product widgets — alt text on featured-product and new-arrival widgets

Safe Merchant Overrides

• Preserves merchant-authored labels — if a product has a custom image label set in admin, that takes precedence
• Replaces Magento defaults — the generic Image / main product photo / filename placeholders get upgraded automatically
• One config toggle — disable the gallery injection separately if you only want alt text on tiles, not captions

Performance Conscious

• Runs inline — no external API calls, no DB writes, pure template rendering
• Scope-cached config reads — uses Magento's cached scope config, zero DB overhead after warm-up
• Template caching — rendered alt text is cached alongside the native image block cache
• Zero JavaScript — fully server-side, no client-side rendering overhead

Clean & Extensible

• MEQP compliant — follows Adobe's Magento Extension Quality Program standards
• Pluggable vision adapter — VisionAdapterInterface lets you swap in OpenAI Vision / Claude Vision for AI-generated fallback alt text
• Optional Panth_ProductGallery wire — integrates automatically when the gallery module is installed
• Well-scoped plugins — four targeted plugins (ImageFactory, Helper\Image, Gallery, Uploader) rather than sweeping preferences

Image alt text is one of the most under-optimized and highest-leverage SEO signals for eCommerce:

1. Image Search Traffic — Google Images is the second-largest search engine. Product images with descriptive alt text rank; images with alt="" or alt="Image" are invisible.
2. On-Page SEO — search engines use alt text to understand page context. A category listing page with 48 products but 48 blank alt attributes ranks worse than one with 48 descriptive alts.
3. Accessibility Compliance — WCAG 2.1 AA and the European Accessibility Act (EAA) both require meaningful alt text on product imagery. Blank alt attributes on eCommerce sites are a legal-risk category.
4. Click-Through Rate — when a product appears in Google Images, the alt text is what gets picked up in the result snippet. Better alt = more qualified clicks.

Manually writing alt text for every product (or every image within every product) doesn't scale past a small catalog. Panth Image SEO lets one merchant-controlled template render correct, scope-aware alt text across the entire catalog in one pass — and refresh instantly when you change the template.

Admin Configuration — Stores → Configuration → Panth Extensions → Image SEO

The admin UI exposes every setting at store-view scope: master toggle, alt template, title template, and gallery-injection toggle. Token and filter reference is inlined under each field so the merchant never has to leave the page to find the syntax.

Before / After — What Changes on Your Storefront

Before: <img alt=""> or <img alt="Image"> — invisible to image search, fails accessibility audits. After: <img alt="Premium Leather Bag - Luma Store View"> — indexed, accessible, on-brand across every store view.

Composer Installation (Recommended)

composer require mage2kishan/module-image-seo
bin/magento module:enable Panth_Core Panth_ImageSeo
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy -f
bin/magento cache:flush

Manual Installation via ZIP

1. Download the latest release ZIP from Packagist or the Adobe Commerce Marketplace
2. Extract the contents to app/code/Panth/ImageSeo/ in your Magento installation
3. Ensure Panth_Core is installed (required dependency)
4. Run the same commands as above starting from bin/magento module:enable

Verify Installation

bin/magento module:status Panth_ImageSeo
# Expected output: Module is enabled

Navigate to Admin → Stores → Configuration → Panth Extensions → Image SEO to configure the module.

All four settings are scope-aware. Configure a shorter alt template on a mobile-focused store view, a different brand suffix on a wholesale store, or different language alt text per localized store — Magento's scope hierarchy handles the rest.

Every token is written as {{tokenName}} and can be combined with filters using |filterName:arg.

Unknown tokens render as empty strings, so a template like Brand: {{brand}} / {{name}} safely falls back to Brand: / Push It Messenger Bag if the brand token isn't wired up yet. Trailing separators are auto-cleaned.

Filters are chained with | and run left-to-right.

Filters can be chained: {{name|lower|title|truncate:40}} is valid.

Basic name + store view

Alt: {{name}} - {{store}}
Title: {{name}}

Renders as:

Push It Messenger Bag - Luma Store View

Brand-suffixed with truncation (safe for long names)

Alt: {{name|truncate:80}} | Buy Online at {{store}}
Title: {{name}} — {{store}}

Category-scoped alt (when category context is available)

Alt: {{name}} in {{category|default:'our catalog'}}
Title: {{name}}

SKU-prefixed alt (useful for B2B catalogs)

Alt: [{{sku|upper}}] {{name}} | {{store}}
Title: {{name|truncate:60}}

Minimal SEO-only (category pages)

Alt: {{name}}
Title: {{name}}

Multi-store with localized brand in each alt

Configure Alt Text Template at the store-view scope:

• English store view: {{name}} | Premium Quality from {{store}}
• French store view: {{name}} | Qualité Premium - {{store}}
• Wholesale store view: [WHOLESALE] {{name}} - {{store}}

The module hooks every surface where Magento renders an <img> tag for a product:

This breadth matters because Magento 2 has four different code paths that eventually render a product <img>:

1. Magento\Catalog\Block\Product\ImageFactory::create — used by category grids, widgets, related/upsell/cross-sell
2. Magento\Catalog\Helper\Image::getLabel — used by some themes directly
3. Magento\Catalog\Block\Product\View\Gallery::getGalleryImagesJson — the product gallery JSON
4. Custom gallery blocks (Panth_ProductGallery, some premium themes)

Missing any one of these leaves a gap where alt text stays blank or reverts to the Magento default. Panth Image SEO plugs all four, so the rendered HTML across your entire storefront is uniformly template-driven.

Will this overwrite my custom image labels?

No. Merchant-authored labels (anything other than empty, the product name, Image, main product photo, or the raw filename) are preserved. Only Magento's default placeholders get upgraded to template output.

Does it work with Hyva?

Yes. The module injects into getGalleryImagesJson, which Hyva reads for its Alpine.js gallery. Category tile alt attributes go through ImageFactory, which Hyva's product/list.phtml also uses.

Does it work with Luma?

Yes. Luma's fotorama gallery reads from the same caption field, and Luma's category grid uses the same ImageFactory path.

Is Panth_Core required?

Yes. mage2kishan/module-core is a required dependency and is pulled in automatically by Composer. Core provides the admin tab layout and common utilities.

Can I use AI-generated alt text?

Yes. The module ships with a VisionAdapterInterface and a NullVisionAdapter default. You can swap the preference in your di.xml to a custom adapter that calls OpenAI Vision, Claude Vision, or Google Cloud Vision for a vision-generated alt as the fallback when templates render empty. The vision adapter only fires when no template output was produced.

Does it support multi-store / multi-language?

Yes. Every configuration setting respects Magento's standard scope hierarchy (default → website → store view). Configure a different alt template per store view and the plugins automatically honor it.

What about the title attribute on <img> tags?

The module renders a separate title template so you can produce short, branded titles ({{name}}) while the alt attribute carries the SEO keyword copy ({{name}} | {{store}} | {{category}}).

Can I disable it temporarily?

Yes. Flip the master toggle to No in admin config and all plugins become no-ops instantly. The module's index data is not deleted, so re-enabling is instant.

Does it touch the database?

No. The module is pure template rendering — no DB tables created, no writes. All state lives in Magento's cached scope config.

What if I want to disable only the gallery injection but keep tile alt working?

Set Apply to Gallery Images JSON to No. The master toggle stays on, so category tiles and widgets still get template alt; only the gallery JSON is left untouched.

Is it compatible with Varnish / Redis FPC?

Yes. The module doesn't cache anything itself — it relies on Magento's native block cache and FPC. Template rendering is idempotent, so cache hit rate is unaffected.
