Etechflow_CanonicalHreflang

Canonical URLs + hreflang tags for Magento 2 — de-duplicates the URL variants that leak SEO equity and serves the right store view per locale. Part of the Etechflow SEO Suite.

Why

Magento generates the same content under many URLs — a product reachable under several category paths, category pages with ?colour=red&price=10-20, ?p=2 pagination, and tracking-param variants. Without a clean canonical, Google splits ranking signals across all of them. This module emits one authoritative canonical per page, and for multi-store catalogues, hreflang links so each locale's customers land on the right store view.

Features

Canonical

• Product / category / CMS pages (each toggleable).
• Category-free product canonical — a product in 5 categories still has one canonical.
• Strips query parameters — ?filter, ?sort, ?utm_* all canonicalise to the clean URL.
• Pagination control — self-referencing (?p=2 canonicalises to itself, Google-recommended) or consolidate-to-page-1.
• De-dupes — removes any existing canonical (e.g. Magento core's) so you never emit two.

Hreflang

• rel="alternate" links across every active store view.
• Each store's code auto-derived from its Locale (en_GB → en-gb), or overridden per store (1:en-gb).
• Optional x-default.

How it works

A single plugin on Magento\Framework\View\Result\Page::renderResult resolves the current entity and adds the <link> tags via PageConfig remote assets — so they render in any theme, including Hyvä, with no template changes. Service\CanonicalResolver and Service\HreflangResolver compute the URLs.

Install

composer require etechflow/module-canonical-hreflang
bin/magento module:enable Etechflow_CanonicalHreflang
bin/magento setup:upgrade
bin/magento setup:di:compile     # production

Configure

Stores → Configuration → Etechflow → Canonical & Hreflang: master Enable, then the canonical toggles (product/category/CMS, strip-query, pagination mode) and hreflang (enable, x-default store, per-store overrides).

Tip: turn off Magento's own canonical (Catalog → Catalog → Search Engine Optimization) — this module dedupes it anyway, but disabling avoids the wasted work.
