Auto Meta Tag Generator

Auto Meta Tag Generator is an extension for Magento 2 that automatically writes SEO meta title, meta description, and meta keywords for every product — and, optionally, every category — using admin-configurable placeholder templates such as {{name}} | {{attribute_set}} | {{store_name}}. The moment a product is saved with a blank Meta Title or Meta Description, the extension fills it in immediately; fields an admin has already filled in are never touched. The same generation engine also reaches products the storefront save event never sees: CSV import, an Admin grid mass action, a CLI command, and a nightly cron safety net all produce identical, on-brand SEO copy. After installing, a merchant with thousands of unoptimized product pages can run a single command and see every blank meta tag filled in within minutes, without touching a single product record by hand. 

Features

• Automatic Generation on Save — fills blank Meta Title, Meta Description, and Meta Keywords the moment a product or category is saved, from the admin form, REST, or GraphQL.
• Configurable Placeholder Templates — build title and description templates from name, sku, price, category, attribute set, short description, store name, and any custom EAV attribute via attribute:CODE.
• Separate Category Templates — categories use their own independent title and description templates, toggled on independently from products.
• Smart Placeholder Cleanup — a placeholder that resolves to nothing is removed automatically, along with any leftover separator punctuation left behind.
• Word-Boundary Truncation — configurable maximum length per field, always cut at the last full word with an optional ellipsis, never mid-word.
• Admin Mass Action — Regenerate Meta Tags (Fill Blanks Only) or (Overwrite Existing) directly from the Catalog Products grid, for any number of selected products at once.
• CLI Command — a console command with store, SKU, force, and dry-run options for safe bulk regeneration and automation.
• CSV Import Support — generates meta tags automatically for products imported with blank meta fields.
• Nightly Cron Safety Net — a scheduled job catches products that bypassed save and import entirely, such as rows written directly to the database by a third-party integration.
• Dedicated Logging — every generation action is written to its own log file for easy troubleshooting.
• Store-View Scope Throughout — every setting is store-view scoped, ready for multi-store and multi-language catalogs.
• Zero Core Code Modifications — built entirely on plugins, an observer, and Magento’s dependency injection. No class rewrites, no patches, upgrade-safe by design.

How It Works

After enabling the extension, go to Stores → Configuration → Mage2Expert → Auto Meta Tag Generator and review the default Product Meta Title Template and Product Meta Description Template — both are pre-filled and ready to use, or fully customizable with placeholders. Save any product with a blank Meta Title or Meta Description and the field is filled in immediately using the configured template. Existing catalogs are covered too: select products in the grid and run Regenerate Meta Tags, or process the whole catalog from the command line with a single flag. 

Templates & Placeholders

Both product and category templates support the same placeholder syntax:

• name — product or category name
• sku and price — product SKU and formatted price
• category — first assigned category (product) or parent category (category)
• attribute_set — attribute set name
• short_description — short description, HTML stripped
• store_name — current store’s name
• attribute:CODE — any EAV attribute value by its attribute code, e.g. attribute:color

A placeholder that resolves to nothing is removed automatically, along with any leftover separator characters left dangling around it, so templates always read cleanly no matter which fields a given product has filled in. 

Bulk Tools for Existing Catalogs

Two grid actions — Regenerate Meta Tags (Fill Blanks Only) and Regenerate Meta Tags (Overwrite Existing) — let merchants process any number of selected products at once, each with its own confirmation dialog. The same work is available from the command line, with options to target a single store or SKU, force-overwrite existing values, and preview changes with a dry run before committing anything. 

Use Cases

• Large catalogs with thousands of SKUs — eliminate blank meta tags across an entire catalog in minutes instead of manually editing every product.
• Frequent CSV imports — every newly imported product gets SEO-ready meta tags automatically, even when the supplier feed never includes them.
• Multi-store, multi-language catalogs — configure a different template per store view with no extra setup.
• Agencies managing many Magento stores — standardize SEO meta tag formatting across client catalogs with a single, reusable template.
• Stores integrating third-party product feeds — the nightly cron safety net catches records written directly to the database by external systems.
