      Bonjourno from Wetherby UK...

      Ive used a package called screamong frog to diagnose canonical errors but can anyone tell me what this means? http://i216.photobucket.com/albums/cc53/zymurgy_bucket/understand-occurances-canonical.jpg

      Thanks in advance.

          Looks like you may have an issue there. The "address" and "canonical 1" should match about 99% of the time. Right now you're telling Google to index all those different address pages as a single URL (About/right-to-manage)... something to look at - and the suggestions below are both good as well.

          -Dan

            I agree with what Streamline Metrics said, I just want to add to this by linking you to a great SEOmoz post on canonicalization which may help you clear things up more.

            In your case, having 1 rel="canonical" tag per page is what you want, so you should be fine with that, just make sure that the canonical tags (listed under canonical 1 in Screaming Frog) is the actual URL that you want.

            Hope this helps

              It simply means how many canonical tags are found on that specific page. So if you had two rel=canonical tags on a page, it would say 2 occurrences. For more info, check out http://www.screamingfrog.co.uk/seo-spider/user-guide/tabs/

                Quick Fix to "Duplicate page without canonical tag"?

                When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’.  The majority of the 665 pages in that section are from a test environment. If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors? That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests.  It seems like a simple effective solution.  Are we missing something?

                Do Canonical Tags Pass Link Juice?

                I have an ecommerce website where some pages link to a product page with a different URL. EXAMPLE: 1: /category/product1.html (not indexed by Google) with canonical pointing to product1.html Other page link to the product like below. 2: product1.html (indexed by Google) Now the question is, does 1: pass any link juice to product1.html or not? Is it worth to change everything and link only to one URL? My site is running on Magento!

                Does Google read dynamic canonical tags?

                Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

                If you use canonicals do the meta descriptions need to be different?

                For example, we have 3 different subsites with the same pages. We will put canonicals so they reference the main pages. Do the meta descriptions have to be different for each of the three pages? How does Google handle meta data when using canonicals?

                Link rel="prev" AND canonical

                Hi guys, When you have several tabs on your website with products, you can most likely navigate to page 2, 3, 4 etc...
                You can add the link rel="prev" and link rel="next" tags to make sure that 1 page get's indexed / ranked by Google. am I correct? However this still means that all the pages can get indexed, right? For example a webshop makes use of the link rel="prev" and ="next" tags. In the Google results page though, all the seperate tabs pages are still visible/indexed..
                http://www.domain.nl/watches/?tab=1
                http://www.domain.nl/watches/?tab=24
                http://www.domain.nl/watches/?tab=19
                etc..... Can we prevent this, and make sure only the main page get's indexed and ranked,  by adding a canonical link on every 'tab page' to the main page --> www.domain.nl/watches/ I hope I explained it well and I'm looking forward to hearing from you. Regards, Tom

                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.

                Should there be a canonical tag on my 404 error page?

                In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
