      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/

                Unsolved Question about a Screaming Frog crawling issue

                technical seo crawl errors

                Hello, I have a very peculiar question about an issue I'm having when working on a website. It's a WordPress site and I'm using a generic plug in for title and meta updates. When I go to crawl the site through screaming frog, however, there seems to be a hard coded title tag that I can't find anywhere and the plug in updates don't get crawled. If anyone has any suggestions, thatd be great. Thanks!

                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.

                Can you use Screaming Frog to find all instances of relative or absolute linking?

                My client wants to pull every instance of an absolute URL on their site so that they can update them for an upcoming migration to HTTPS (the majority of the site uses relative linking). Is there a way to use the extraction tool in Screaming Frog to crawl one page at a time and extract every occurrence of _href="http://" _? I have gone back and forth between using an x-path extractor as well as a regex and have had no luck with either. Ex. X-path: //*[starts-with(@href, “http://”)][1] Ex. Regex: href=\”//

                Exclude status codes in Screaming Frog

                I have a very large ecommerce site I'm trying to spider using screaming frog. Problem is I keep hanging even though I have turned off the high memory safeguard under configuration. The site has approximately 190,000 pages according to the results of a Google site: command. The site architecture is almost completely flat. Limiting the search by depth is a possiblity, but it will take quite a bit of manual labor as there are literally hundreds of directories one level below the root. There are many, many duplicate pages. I've been able to exclude some of them from being crawled using the exclude configuration parameters. There are thousands of redirects. I haven't been able to exclude those from the spider b/c they don't have a distinguishing character string in their URLs. Does anyone know how to exclude files using status codes? I know that would help. If it helps, the site is kodylighting.com. Thanks in advance for any guidance you can provide.

                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 ?

                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?

                Robots.txt and canonical tag

                In the SEOmoz post - http://www.seomoz.org/blog/robot-access-indexation-restriction-techniques-avoiding-conflicts, it's being said - If you have a robots.txt disallow in place for a page, the canonical tag will never be seen. Does it so happen that if a page is disallowed by robots.txt, spiders DO NOT read the html code ?
