      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.

            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/

                What could cause Google to not honor canonical URLs?

                I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

                Trailing slash URLs and canonical links

                Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
                However, it sticks to domain names only.
                What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
                https://www.domain.com
                https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
                Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
                Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!
                G

                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!

                Do URLs with canonical tags get indexed by Google?

                Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop. Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

                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

                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!

                Rel = prev next AND canonical?

                I have product category pages that correctly have the prev next but the moz crawl is giving me duplicate content errors.  I would not think I also need to have canonical - but do I ?

                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.
