          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.

            Optimization expert suggesting we add Canonical tag to every page on site

            canonical technical seo

            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!

            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!

            Unsolved Product search menu Canonical tag and missing description errors

            canonical search results metadata meta tags

            We have recently migrated to an entirely new website, Moz is now picking up many meta data issues, the bulk of these are from descriptions and missing canonical tags from product search pages (i.e, customer searches for a product and the search results page is the one being picked up, is this is a big issue for the site's overall SEO rating and if so what can be done to resolve this?

            Rel=canonical and redirect on same page

            Hi Guys, Am I going slightly mad but why would you want to have a redirect and a canonical redirecting back to the same page. For Instance https://handletrade.co.uk/pull-handles/pull-handles-zcs-range/d'-pull-handle-19mm-dia.-19-x-150mm-ss/?tag=Dia.&page=2 and in the source code:- <link href="<a class="attribute-value">https://handletrade.co.uk/d'-pull-handle-19mm-dia.-19-x-150mm-ss/</a>" rel="<a class="attribute-value">canonical</a>" /> Perfect! exactly what it is intended to do. But then this page is 301 redirected tohttps://handletrade.co.uk/pull-handles/pull-handles-zcs-range/d'-pull-handle-19mm-dia.-19-x-150mm-ss/ The site is built in open cart and I think it's the SEO plugin that needs tweaking. Could this cause poor SERP visibility? This is happening across the whole site. Surely the canonical should just point to the proper page and then there is no need for an additional bounce.

            Should I use canonical?

            I'm working on a site that sells audio tracks, the site is a Wordpress build. I've got Yoast and XML Sitemaps running for SEO. The site has been developed (not by myself) to use a flash based audio player. Now this player offers the ability to share, sell products etc... The player has been placed on the homepage and the main music catalog page. The main catalog page has had a custom page type created for itself. This page has been created in such a way that if you visit the actual page from dashboard > Pages and add content then no content will appear on the page. Even the page header is pulled from the PHP. So really as far as I am aware no real content is being seen on the page by a search engine. Except the content on the side bars (it has 2 sidebars on either side of the page.) The homepage has an introductory paragraph and header which are editable via the normal method in Wordpress. A custom post type has been created specifically for music items. When a music item is uploaded it is added to the music item feed on the homepage and music catalog pages. It also creates a separate post for the item itself. These items at the moment also have 'no content' as they are only sidebars with a flash music player. I've started to add short paragraphs and headers to them so there is content on the music item posts. I cannot however, in the time frame/budget start entering deeply descriptive content about each item. (I considered adding the intro paragraph from the homepage and using a canonical tag to the homepage on every music item). So here is my question. What do I do with these music items? Do I use canonical and point them toward the music catalog or the homepage? If so which one? I want the homepage or music catalog page to rank well and I am concerned that search engines aren't going to see these most vital parts of the site. I don't think individual items ranking is helpful, so what do i do?!?! The home and catalog pages are the two main pages of the site. I am going to advise a new player, page type etc... be utilised but at the moment I need a solution quickly. Any help will be much appreciated.

            When to use canonical urls

            I will be the first to admit I am never really 100% sure when to use canonical urls. I have a quick question and I am not really sure if this is a situation for a canonical or not. I am looking at a my friends building website and there are issues with what pages are ranking. Basically there homepage is focusing on the building refurbishment location but for some reason in internal page is ranking for that keyword and it is not mentioned at all on that page. Would this be a time to add the homepage url and a canonical on the ranking page (using yoast plugin) to tell Google that the homepage is the preferred page? Thanks Paul

            Canonical on ecommerce site

            I have read tons of guides about canonical implementaiton but still am confused about how I should best use it. On my site with tens of thousands of urls and thousands of afiiliates and shopping networks sending traffic,  is it smart to simply add the tag to every page and redirect to the same url. In doing this would that solve the problem of a single page having many different entrances with different tracking codes? Is there a better way to handle this? Also is there any potential problems with rolling out the tag to all pages if they are simply refrencing themselves in the tag? Thanks in advance.
