      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!

                URL has caps, but canonical does not. Now what?

                Hi, Just started working with a site that has the occasional url with a capital, but then the url in the canonical as lower case. Neither, when entered in a browser, resolves to the other. It's a Shopify site. What do you think I should do?

                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?

                Can I set a canonical tag to an anchor link?

                I have a client who is moving to a one page website design.  So, content from the inner pages is being condensed in to sections on the 'home' page.  There will be a navigation that anchor links to each relevant section.  I am wondering if I should leave the old pages and use rel=canonical to point them to their relevant sections on the new 'home' page rather than 301 them.  Thoughts?

                Screaming Frog showing 503 status code. Why?

                Screaming Frog is showing a 503 code for images. If I go and use a header checker like SEOBook it shows 200. Why would that be? Here is an example link- http://germanhausbarn.com/wp-content/uploads/2014/07/36-UPC-5145536-John-Deere-Stoneware-Logo-Mug-pair-25.00-Heavy-4-mugs-470x483.jpg

                Screaming Frog Content Showing charset=UTF-8

                I am running a site through Screaming Frog and many of the pages under "Content" are reading text/html; charset=UTF-8. Does this harm ones SEO and what does this really mean? I'm running his site along with this competitors and the competitors seems very clean with content pages reading text/html. What does one do to change this if it is a negative thing? Thank you

                Do I need to add canonical link tags to pages that I promote & track w/ UTM tags?

                New to SEOmoz, loving it so far. I promote content on my site a lot and am diligent about using UTM tags to track conversions & attribute data properly. I was reading earlier about the use of link rel=canonical in the case of duplicate page content and can't find a conclusive answer whether or not I need to add the canonical tag to these pages. Do I need the canonical tag in this case? If so, can the canonical tag live in the HEAD section of the original / base page itself as well as any other URLs that call that content (that have UTM tags, etc)? Thank you.

                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.
