      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/

                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!

                How long does it take for canonical tags to work

                How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

                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

                Server is taking too long to respond - What does this mean?

                A client has 3 sites that he would like for me to look at.  Whenever I attempt to on my home internet I get this message: The connection has timed out
                The server is taking too long to respond. When I take my iphone off wifi and use AT&T, the site comes up fine.  What is going on here?

                Canonical tag for Home page: with or without / at the end???

                Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL. We have incoming links to the homepage as http://www.mysite.com (without the backslash), and as http://www.mysite.com/ (with the backslash), and as http://www.mysite.com/index.html I know that there should be 301 redirects to just one version, but I need to know more about the canonical tags... Which should the canonical tag be??? (without the backslash) or (with the backslash) Thanks for your help! 🙂

                Rel=Canonical, WWW vs non WWW and SEO

                Okay so I'm a bit of a loss here.  For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar.  I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise?  Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same?  Or am I wrong and all that link juice and authority passes just the same?

                Syndication: Link back vs. Rel Canonical

                For content syndication, let's say I have the choice of (1) a link back or (2) a cross domain rel canonical to the original page, which one would you choose and why? (I'm trying to pick the best option to save dev time!) I'm also curious to know what would be the difference in SERPs between the link back & the canonical solution for the original publisher and for sydication partners? (I would prefer not having the syndication partners disappeared entirely from SERPs, I just want to make sure I'm first!) A side question: What's the difference in real life between the Google source attribution tag & the cross domain rel canonical tag? Thanks! PS: Don't know if it helps but note that we can syndicate 1 article to multiple syndication partners (It would't be impossible to see 1 article syndicated to 50 partners)
