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.)"

Should we use Cloudflare
Hi all, we want to speed up our website (hosted in Wordpress, traffic around 450,000 page views monthly), we use lots of images. And we're wondering about setting up on Cloudflare, however after searching a bit in Google I have seen some people say the change in IP, or possible sharing of Its with bad neighbourhoods, can really hit search rankings. So, I was wondering what the latest thinking is on this subject, would the increased speed and local server locations be a boost for SEO, moreso than a potential loss of rankings for changing IP? 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.

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

Canonical homepage link uses trailing slash while default homepage uses no trailing slash, will this be an issue?
Hello, 1st off, let me explain my client in this case uses BigCommerce, and I don't have access to the backend like most other situations. So I have to rely on BG to handle certain issues. I'm curious if there is much of a difference using domain.com/ as the canonical url while BG currently is redirecting our domain to domain.com. I've been using domain.com/ consistently for the last 6 months, and since we switches stores on Friday, this issue has popped up and has me a bit worried that we'll loose somehow via link juice or overall indexing since this could confuse crawlers. Now some say that the domain url is fine using / or not, as per - https://moz.com/community/q/trailing-slash-and-rel-canonical But I also wanted to see what you all felt about this. What says you?

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!

Is using a Href in Div OK?
Hi, I was just wondering what your thoughts are on using a Href in a Div, which contains anchor text. We currently use the Href on the div, as opposed to just the anchor text as I want the whole div to be clickable as opposed to just the anchor text. So currently I have: Keword 1

Keyword 2 However I would assume a search engine is smart enought to know its the same thing??? Thanks0 -
Use of Meta Tag - MSSmartTagsPreventParsing
We've inherited some sites from another developer that had the following tag: All references I can find to it are from 2004. What is the purpose and is it worth including in pages/sites we build?
