              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.

                Dynamic Canonical Tag for Search Results Filtering Page

                canonical indexation search page categorization search results crawl

                Hi everyone, I run a website in the travel industry where most users land on a location page (e.g. domain.com/product/location, before performing a search by selecting dates and times. This then takes them to a pre filtered dynamic search results page with options for their selected location on a separate URL (e.g. /book/results). The /book/results page can only be accessed on our website by performing a search, and URL's with search parameters from this page have never been indexed in the past. We work with some large partners who use our booking engine who have recently started linking to these pre filtered search results pages. This is not being done on a large scale and at present we only have a couple of hundred of these search results pages indexed. I could easily add a noindex or self-referencing canonical tag to the /book/results page to remove them, however it’s been suggested that adding a dynamic canonical tag to our pre filtered results pages pointing to the location page (based on the location information in the query string) could be beneficial for the SEO of our location pages. This makes sense as the partner websites that link to our /book/results page are very high authority and any way that this could be passed to our location pages (which are our most important in terms of rankings) sounds good, however I have a couple of concerns. • Is using a dynamic canonical tag in this way considered spammy / manipulative? • Whilst all the content that appears on the pre filtered /book/results page is present on the static location page where the search initiates and which the canonical tag would point to, it is presented differently and there is a lot more content on the static location page that isn’t present on the /book/results page. Is this likely to see the canonical tag being ignored / link equity not being passed as hoped, and are there greater risks to this that I should be worried about? I can’t find many examples of other sites where this has been implemented but the closest would probably be booking.com. https://www.booking.com/searchresults.it.html?label=gen173nr-1FCAEoggI46AdIM1gEaFCIAQGYARS4ARfIAQzYAQHoAQH4AQuIAgGoAgO4ArajrpcGwAIB0gIkYmUxYjNlZWMtYWQzMi00NWJmLTk5NTItNzY1MzljZTVhOTk02AIG4AIB&sid=d4030ebf4f04bb7ddcb2b04d1bade521&dest_id=-2601889&dest_type=city& Canonical points to https://www.booking.com/city/gb/london.it.html In our scenario however there is a greater difference between the content on both pages (and booking.com have a load of search results pages indexed which is not what we’re looking for) Would be great to get any feedback on this before I rule it out. Thanks!

                "Duplicate without user-selected canonical” - impact to Google Ads costs

                google ads canonical

                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. 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/" /> Naturally this si reflected in ""Duplicate without user-selected canonical” . Issue
                We create the same ad in Google Ads for 2 domains. So the content is mostly identical, ads are identical, target URLs differ only in domain. Yet Google Ads “Quality score” is different (10/10 vs. 6/10) and “Landing page experience” is very different (Above average vs. Average). Some members of our team think lower “Landing page experience” increases the Google Ads costs, which I personally don't believe, but I want to double check. Question: Can “Duplicate without user-selected canonical” issue decrease the “Landing page experience” rating and as result can it cause higher Google ads costs? Any suggestions/ideas appreciated, thanks. Regards.

                "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.

                Question on noscript tags and indexing

                If I have a <noscript>tag on every page of my website with the same sentence over and over saying something to the effect of "Sorry our site uses Javascript, please enable javascript for the full site experience.", Webmaster Tools will tell me that one of the most common words on my site is "Javascript".</p> <p>Is this something to be concerned about from an SEO perspective? My site is obviously not about Javascript and I don't want to dilute my page's topic or authority by repeating words that are not relevant to the topic of my site.</p> <p>Thanks!</p></noscript>

                Missing meta descriptions from Google SERPs

                Hullo all, I run an e-commerce website and hence have a lot of product category/sub-category pages to handle. Despite giving each of these category pages meta descriptions, in the Google SERPs, a lot of these descriptions don't show up fully. Rather, only half the text that I'd inputed as my meta desc. shows up; the other half has generic stuff from that page given.  I've attached a screen shot to give you an example of what comes up in the SERPs. Could you please tell me what exactly is the problem? Is it a coding issue? Or has Google not crawled that page? Need help asap! Thank you in advance! aE9RKXJ

                Should I include tags in sitemap?

                Hello All, I was wondering if you should include tags and categories in your sitemap. In the past on previous blogs I have always left tags and categories out. The reason for this is a good friend of mine who has been doing SEO for a long time and inhouse always told me that this would result in duplicate content. I thought that it would be a great idea to get some input from the SEOmoz community as this obviously has a big affect on your blog and the number of pages indexed. Any help would be great. Thanks, Luke Hutchinson.
