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

Good to use disallow or noindex for these?
Hello everyone, I am reaching out to seek your expert advice on a few technical SEO aspects related to my website. I highly value your expertise in this field and would greatly appreciate your insights.

Below are the specific areas I would like to discuss: a. Double and Triple filter pages: I have identified certain URLs on my website that have a canonical tag pointing to the main /quick-ship page. These URLs are as follows: https://www.interiorsecrets.com.au/collections/lounge-chairs/quick-ship+black
https://www.interiorsecrets.com.au/collections/lounge-chairs/quick-ship+black+fabric Considering the need to optimize my crawl budget, I would like to seek your advice on whether it would be advisable to disallow or noindex these pages. My understanding is that by disallowing or noindexing these URLs, search engines can avoid wasting resources on crawling and indexing duplicate or filtered content. I would greatly appreciate your guidance on this matter. b. Page URLs with parameters: I have noticed that some of my page URLs include parameters such as ?variant and ?limit. Although these URLs already have canonical tags in place, I would like to understand whether it is still recommended to disallow or noindex them to further conserve crawl budget. My understanding is that by doing so, search engines can prevent the unnecessary expenditure of resources on indexing redundant variations of the same content. I would be grateful for your expert opinion on this matter. Additionally, I would be delighted if you could provide any suggestions regarding internal linking strategies tailored to my website's structure and content. Any insights or recommendations you can offer would be highly valuable to me. Thank you in advance for your time and expertise in addressing these concerns. I genuinely appreciate your assistance. If you require any further information or clarification, please let me know. I look forward to hearing from you. Cheers!0 -
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!

Google serp pagination issue
We are a local real estate company and have landing pages for different communities and cities around our area that display the most recent listings. For example: www.mysite.com/wa/tumwater is our landing page for the city of Tumwater homes for sale. Google has indexed most of our landing pages, but for whatever reason they are displaying either page 2, 3, 4 etc... instead of page 1. Our Roy, WA landing page is another example. www.mysite.com/wa/roy has recently been showing up on page 1 of Google for "Roy WA homes for sale", but now we are much further down and www.mysite.com/wa/roy?start=80 (page 5) is the only page in the serps. (coincidentally we no longer have 5 pages worth of listings for this city, so this link now redirects to www.mysite.com/wa/roy.) We haven't made any major recent changes to the site. Any help would be much appreciated! *You can see what my site is in the attached image... I just don't want this post to show up when someone google's the actual name of the business 🙂 nTTrSMx.jpg C4mhfgh.jpg

Do I have a problem with missing pages in Screaming Frog?
We have category pages and some of those pages have pagination due to us having additional items. Screaming Frog could not find the items that were after page 1. Is this a problem for Google? These item pages are still in the sitemap. I am sure they can find them to index them but does it hurt rankings at all.

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Effective use of hReview
Hi fellow Mozzers! I am just in the process of adding various reviews to our site (a design agency), but I wanted to use the ratings in different ways depending on the page. So for the home page and the services (branding, POS, direct mail etc) I wanted to aggregate relevant reviews (giving us an average of all reviews for the home page, an average of ratings from all brand projects and so on). Then, I wanted to put specific reviews on our portfolio pages, so the review relates specifically to that project. This is the easiest to do as the hReview generator is geared up for reviews that come from one source, but I can't find a way of aggregating the star ratings to make an average rating rich snippet. Anyone know where I can get the coding for this? Thanks in advance! Nick.
