Hi guys,
We're currently launching a new page, and we have an optimization and technical SEO expert (highly rated on Upwork, very intelligent, has solved complicated issues in the past and improved our Core Web Vitals greatly) suggesting we put canonical tags on every page of site, pointing to itself (other than the case of where canonicals should point to other page, we have those listed separately.
Do you guys see a benefit to this? Could it harm us? He says large retailers do this, couldn't quite glean the benefit from it though. Current site ranks well and isn't set up like this.
Any insight would be much appreciated!
Thanks!
