Canonical issues using Screaming Frog and other tools?
-
In the Directives tab within Screaming Frog, can anyone tell me what the difference between "canonicalised", "canonical", and "no canonical" means? They're found in the filter box. I see the data but am not sure how to interpret them. Which one of these would I check to find canonical issues within a website? Are there any other easy ways to identify canonical issues?

Hello
I spotted this thread and was just about to reply, but Dirk has answered it all perfectly. Thanks Dirk!
Under 'reports' there's also a 'canonical errors' report which will show canonicals with various technical issues - Those that are blocked by robots.txt, have no response, 3XX redirect, 4XX or 5XX error (essentially anything other than a 200 ‘OK’ response). It will also show any URLs discovered only via a canonical, that are not linked to internally from the sites own link structure (in the ‘unlinked’ column when ‘true’).
Hope that helps anyway.
Cheers!

Hi,
The difference between them
-
canonical : url has a canonical url - which can be self-referencing (canonical url = url) or not
-
canonicalised: url has a canonical url which is not self-referencing (canonical url <> url)
-
no canonical : quite obvious - the url has no canonical.
Potential issues could be - url's that you would like to have a canonical don't have a canonical or url's that are canonicalised don't have the right canonical url. You can use the lists (both canonicalised & no canonical) from Screaming Frog to check them - but it's up to you to judge whether the canonical is ok or not (no automated tool can guess what your intentions are).
Typical mistakes with canonicals: all url's have the same canonical url (like the homepage), or have canonical url's that do not exist. You could also check this with Screaming Frog using the setting "respect canonicals" - this way only the canonical url's will be shown in the listing.Also keep in mind that canonical url's are merely a friendly request to Google to index the canonical rather than the normal url - but it's not an obligation for Google to do this (check https://support.google.com/webmasters/answer/139066?hl=en quote: "the search results will be more likely to show users that URL structure. (Note: We attempt to respect this, but cannot guarantee this in all cases.)"

Does using a canonical with ?utm_source=gmb cause any issues?
All of our URLs in Google My Business are tagged with ?utm_source=gmb. This way when people click on it within a Google Map listing, knowledge graph, etc we know it came from there. I'm assuming using a canonical on all ?_utm_source _pages (we have others, including some in the index) won't cause any problems with this, correct? Since they're not technically traditional organic SERPs? Dumb question I know, but better safe than sorry. Thanks.

Should I use a canonical URL for images uploaded to a blog post in Wordpress?
Hi, I have a wordpress website that has articles/news posts witch contain imagery. I've noticed that in the Media Library, when you upload an image to a blog post it generates a new permalink ...article-name/article-image-01.jpg I have Yoast SEO plugin and have the option to set a canonical URL for this image. Should I point it back to the actual article? Thanks for any helpers with this.

If I'm using a compressed sitemap (sitemap.xml.gz) that's the URL that gets submitted to webmaster tools, correct?
I just want to verify that if a compressed sitemap file is being used, then the URL that gets submitted to Google, Bing, etc and the URL that's used in the robots.txt indicates that it's a compressed file. For example, "sitemap.xml.gz" -- thanks!

Sitelinks Issue - Different Languages
Hey folks, We run different ccTLD's for revolveclothing.com (revolveclothing.es, revolveclothing.com.br, etc. etc.) and they all have their own WMT/Google Console with their own href lang tags etc. The problem is this. https://www.google.fr/#q=revolve+clothing When you look at the sitelinks, you'll see that one of them (sales page) happens to be in Portuguese on the French site. Can anyone investigate and see why?

Canonical Tag when using Ajax and PhantomJS
Hello, We have a site that is built using an AJAX application. We include the meta fragment tag in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

Using the Google Remove URL Tool to remove https pages
I have found a way to get a list of 'some' of my 180,000+ garbage URLs now, and I'm going through the tedious task of using the URL removal tool to put them in one at a time. Between that and my robots.txt file and the URL Parameters, I'm hoping to see some change each week. I have noticed when I put URL's starting with https:// in to the removal tool, it adds the http:// main URL at the front. For example, I add to the removal tool:- https://www.mydomain.com/blah.html?search_garbage_url_addition On the confirmation page, the URL actually shows as:- http://www.mydomain.com/https://www.mydomain.com/blah.html?search_garbage_url_addition I don't want to accidentally remove my main URL or cause problems. Is this the right way this should look? AND PART 2 OF MY QUESTION If you see the search description in Google for a page you want removed that says the following in the SERP results, should I still go to the trouble of putting in the removal request? www.domain.com/url.html?xsearch_... A description for this result is not available because of this site's robots.txt – learn more.

Redirect non-www if using canonical url?
I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks
