                  There's two answers to this.

                  One is that whilst it's best practice for all URLs to have a canonical (even if it's self-referencing), if this resource has no duplicates, it's not mandatory.

                  The other is that yes, you can add a canonical tag to a web page. You'd have to do it at the HTTP header level.

                    How Can I influence the Google Selected Canonical

                    canonical ranking issue subdomain indexation

                    Our company recently rebranded and launched a new website. The website was developed by an overseas team and they created the test site on their subdomain. The only problem is that Google crawled and indexed their site and ours. I noticed Google indexed their sub domain ahead of our domain and based on Search Console it has deemed our content as the duplicate of theirs and the Google selected theirs as the canonical.
                    The website in question is https://www.spaziointerni.us
                    What would be the best course of action to get our content ranked and selected instead of being marked as the duplicate?
                    Not sure if I have to modify the content to make it more unique or have them submit a removal in their search console.
                    Our indexed pages continue to go down due to this issue.
                    Any help is greatly appreciated.

                    "Duplicate without user-selected canonical” - impact to SERPs

                    canonical international seo

                    Hello, we are facing some issues on our project and we would like to get some advice. Scenario
                    We run several websites (www.brandName.com, www.brandName.be, www.brandName.ch, etc..) all in French language . All sites have nearly the same content & structure, only minor text (some headings and phone numbers due to different countries are different). There are many good quality pages, but again they are the same over all domains. Goal
                    We want local domains (be, ch, fr, etc.) to appear in SERPs and also comply with Google policy of local language variants and/or canonical links. Current solution
                    Currently we don’t use canonicals, instead we use rel="alternate" hreflang="x-default": <link rel="alternate" hreflang="fr-BE" href="https://www.brandName.be/" /> <link rel="alternate" hreflang="fr-CA" href="https://www.brandName.ca/" /> <link rel="alternate" hreflang="fr-CH" href="https://www.brandName.ch/" /> <link rel="alternate" hreflang="fr-FR" href="https://www.brandName.fr/" /> <link rel="alternate" hreflang="fr-LU" href="https://www.brandName.lu/" /> <link rel="alternate" hreflang="x-default" href="https://www.brandName.com/" /> Issue
                    After Googlebot crawled the websites we see lot of “Duplicate without user-selected canonical” in Coverage/Excluded report (Google Search Console) for most domains. When we inspect some of those URLs we can see Google has decided that canonical URL points to (example): User-declared canonical: None
                    Google-selected canonical: …same page, but on a different domain Strange is that even those URLs are on Google and can be found in SERPs. Obviously Google doesn’t know what to make of it. We noticed many websites in the same scenario use a self-referencing approach which is not really “kosher” - we are afraid if we use the same approach we can get penalized by Google. Question: What do you suggest to fix the “Duplicate without user-selected canonical” in our scenario? Any suggestions/ideas appreciated, thanks. Regards.

                    In Google Webmaster Tools, I have a coverage issue. I am getting this error message: Alternate page with proper canonical tag Status: Excluded. It gives the below blog post page as an example. Any idea how to resolve?

                    301 redirect: canonical or non canonical?

                    Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

                    Multiple H1 tags in Squarespace

                    Hi. I'm using Squarespace, and I've noticed they assign the page title and site title h1 tag status. So if I add an on-page h1 tag, that's three in total. I've seen what Matt Cutts said about multiple h1 tags being acceptable (although that video was back in 2009 and a lot has changed since then). But I'm still a little concerned that this is perhaps not the best way of structuring for SEO. Could anyone offer me any advice? Thanks.

                    Do canonical tags pass all of the link juice onto the URL they point to?

                    I have an ecommerce website where the category pages have various sorting and paging options which add a suffix to the URLs. My site is setup so the root category URL, domain.com/category-name, has a canonical tag pointing to domain.com/category-name/page1/price however all links, both interner & external, point to the former (i.e. domain.com/category-name). I would like to know whether all of the link juice is being passed onto the canonical tag URL? Otherwise should I change the canonical tag to point the other way? Thanks!

                    H1 Tag as Logo on the Homepage.

                    So I was working on a Genesis theme website where they have the H1 Tag as the Logo on the homepage.  I wanted this changed because I always use my H1 tag to include a keyword I want to rank for.  I was told by the Genesis Forum Manager that Yoast said the Logo should be the H1 tag on the homepage.  (Yoast has a WP SEO Plugin that is very popular) That makes no sense to me, so I was looking for Opinions. Thanks,
