Canonical vs. hreflang tagsCanonical and hreflang tags both tell Google the version of the page it is supposed to index and show on SERPs. Like canonical tags, hreflang tags can also be defined as code pieces that provide signals to search bots. Despite their SEO benefits, hreflang and canonical tags can do more harm than good when used improperly. There’s page A referencing page B as canonical, and then page B referencing page C as canonical, which creates a canonical chain. Closing thoughtsDespite some similarities between hreflang and canonical tags, they serve different functions and bring different benefits to the table.
