Use canonical URLs correctly
Canonical tags tell CGM Search which version of a page is the real one — preventing duplicate-content confusion.
The duplicate-URL problem
The same page is often reachable at several URLs — with and without a trailing slash, with tracking parameters, http vs https. Without guidance, that looks like duplicate content and splits your ranking signals.
Point every page at its canonical
A canonical tag in a page's <head> names the single preferred URL for that content. Set it on every page so CGM Search consolidates signals onto one version.
Tip: Each page's canonical should point to itself (its clean, preferred URL) unless it's truly a duplicate of another page.
