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!
Dan

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.)"

What Tools Should I Use To Investigate Damage to my website
I would like to know what tools I should use and how to investigate damage to my website in2town.co.uk I hired a person to do some work to my website but they damaged it. That person was on a freelance platform and was removed because of all the complaints made about them. They also put in backdoors on websites including mine and added content. I also had a second problem where my content was being stolen. My site always did well and had lots of keywords in the top five and ten, but now they are not even in the top 200. This happened in January and feb. When I write unique articles, they are not showing in Google and need to find what the problem is and how to fix it. Can anyone please help

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.

Duplicate Content Issues with Pagination
Hi Moz Community, We're an eCommerce site so we have a lot of pagination issues but we were able to fix them using the rel=next and rel=prev tags. However, our pages have an option to view 60 items or 180 items at a time. This is now causing duplicate content problems when for example page 2 of the 180 item view is the same as page 4 of the 60 item view. (URL examples below) Wondering if we should just add a canonical tag going to the the main view all page to every page in the paginated series to get ride of this issue. https://www.example.com/gifts/for-the-couple?view=all&n=180&p=2 https://www.example.com/gifts/for-the-couple?view=all&n=60&p=4 Thoughts, ideas or suggestions are welcome. Thanks

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

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.

Is there a tool to see all redirects?
I'm thinking this is a silly question, but I've never had to deal with it I thought I'd ask. Ok is there a tool out there that will show all the redirects to a domain. I'm working on a project that I keep stumbling on urls that redirect to the site I'm studying. They don't show up in Open Site or ahrefs as linking domains, but they keep popping up on me. Any thoughts?

Rel canonical between mirrored domains
Hi all & happy new near! I'm new to SEO and could do with a spot of advice: I have a site that has several domains that mirror it (not good, I know...) So www.site.com, www.site.edu.sg, www.othersite.com all serve up the same content. I was planning to use rel="canonical" to avoid the duplication but I have a concern: Currently several of these mirrors rank - one, the .com ranks #1 on local google search for some useful keywords. the .edu.sg also shows up as #9 for a dirrerent page. In some cases I have multiple mirrors showing up on a specific serp. I would LIKE to rel canonical everything to the local edu.sg domain since this is most representative of the fact that the site is for a school in Singapore but...
Technical SEO | | AlexSG
-The .com is listed in DMOZ (this used to be important) and none of the volunteers there ever respoded to requests to update it to the .edu.sg
-The .com ranks higher than the com.sg page for non-local search so I am guessing google has some kind of algorithm to mark down obviosly local domains in other geographic locations Any opinions on this? Should I rel canonical the .com to the .edu.sg or vice versa? I appreciate any advice or opinion before I pull the trigger and end up shooting myself in the foot! Best regards from Singapore!0 -
Using a non-visible H1
I have a developer that wants to use style="text-indent:-9999px" to make the H1 non-visible to the user. Being the conservative person I am, I've never tried this before and worry that Search Engines may think this is a form of cloaking. Am I worrying about nothing? And apologies if it's already been covered here. I couldn't find it. Thanks in advance!!!!
