About the Extension
Duplicate content is one of the most common SEO drags in Shopware – and it usually happens unnoticed: every colour or size variant gets its own URL with almost identical text. Sell across several countries (e.g. .de, .at, .ch) and the problem multiplies. Google then spreads ranking power across many weak pages instead of concentrating it on one strong page. That costs visibility, clicks and revenue.
Canonical Master SEO Pro solves exactly that – automatically and transparently.
WHAT THE PLUGIN DOES FOR YOU
• Automatic canonical tags for variants
For each variant family the plugin determines the strongest variant – by sales, views or stock – and sets it as the canonical target, focusing ranking power
where it matters most.
• Sales-channel mapping for country shops
Selling the same catalogue across multiple country domains? Your AT and CH shops automatically canonicalize to the main shop (e.g. DE) – without maintaining a single URL by hand.
• Duplicate-content analysis that really looks
The plugin detects not only exactly identical descriptions (hash comparison) but also very similar texts (similarity analysis) and groups related products together. You instantly see where the real SEO issues are – and fix them with a single click.
• One central overview instead of spreadsheets
All canonical assignments in one place: filterable by status, sales channel or category, grouped by canonical target, exportable as CSV. Ideal for reporting and team alignment.
• Automation meets control
You decide how much automation you want: "set all automatically" for a quick start, targeted resolution of selected groups, or a manual override via product search. Individual assignments can be locked so automation leaves them alone. In preview mode the plugin calculates everything without emitting anything in the frontend yet – perfect for risk-free testing.
• Built-in SEO safeguard
Configurator parent products are not independently indexable in Shopware. The plugin therefore never chooses them as canonical targets in automatic paths – a classic SEO trap that simply can't happen here.
• Built for large catalogues
The similarity analysis runs asynchronously in the background worker – with a progress display and pause, resume and cancel options. Even shops with several thousand products stay responsive.
DATA PRIVACY
The plugin works entirely inside your shop. It makes no external server calls andshares no data – GDPR-friendly by design.
