                  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.

                    Rel canonical tag from shopify page to wordpress site page

                    shopify wordpress canonical

                    We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

                    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.

                    Div tags vs. Tables

                    Is there any reason NOT to code in tables (other than it being outdated) for SEO reasons?

                    I need help with a PHP canonical URL tags

                    I found a little difficult for me to do a canonical tag in my PHP. On-Page Report Card We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply. I don't know how to tidy my PHP Any suggestion.

                    Adding Rel Canonical to multiple pages

                    Hi, Our CMS generates a lot of duplicate content, (Different versions of every page for 3 different font sizes). There are many other reasons why we should drop this current CMS and go with something else, and we are in the process of doing that. But for now, does anyone know how would I do the following: I've created a spreadsheet that contains the following: Column 1: rel="canonical" tag for URL Column 2: Duplicate Content URL # 1 Column 3: Duplicate Content URL # 2 Column 4: Duplicate Content URL # 3 I want to add the tag from column 1 into the head of every page from column 2,3, and 4. What would be a fast way to do this considering that I have around 1800 rows. Check the screenshot of the builtwith.com result to see more information about the website if that helps. Farris bxySL
