Canonical tags by platform
How to add, view, and override the canonical tag on the content management systems and JavaScript frameworks people actually use.
Every content management system handles the canonical tag a little differently. Some add a self-referencing canonical to every page automatically; some cover only part of your site; and at least one major platform adds no canonical at all unless you switch it on.
Knowing which camp your platform falls into is the difference between trusting a default that is already correct and hunting for a setting that was never enabled. Each guide below explains what the platform does out of the box, where to view and override the canonical URL, the limitations to plan around, and the mistakes that most often send the canonical to the wrong place.
