Diagnosing Canonical Errors Is Screaming frog reliable?
-
Morning from suny & warm wetherby UK

On this page http://www.goldsboroughestates.co.uk/how-we-care-for-you/right-to-manage/ screaming frog is citing a canonical error but I'm confused as this piece of code is in place:
http://www.goldsboroughestates.co.uk/About/right-to-manage" />
So my question is please - "Does this page http://www.goldsboroughestates.co.uk/how-we-care-for-you/right-to-manage/ have a caninical error or is screaming frog useless?
Other examples where screaming frog is picking up canonical errors include:
http://www.goldsboroughestates.co.uk/what-our-customers-say/right-to-manage/
http://www.goldsboroughestates.co.uk/buying-a-home/right-to-manage/Oh forgot to say the preffered version is http://www.goldsboroughestates.co.uk/About/right-to-manage/
Any insights welcvome

Hey,
Long time since the Question, I was just wondering if you worked it out or not.

I think Screaming Frog is just warning you that the canonical version doesn't seem to match the display URL. They can't really tell (we have the same problem in SEOmoz tools) what the "right" canonical is - they can just warn of a mismatch.
I'm a bit confused as to the purpose of the dual URLs here. The best canonical implementation is to use one URL. The canonical tag can act as a band-aid, but consistency is still the best defense. Having multiple paths to the same page is rarely beneficial.

Having spoke to oiur internal helpdesk (Who I trust & do know what theyre talking about) theyve taken a look at:
http://www.goldsboroughestates.co.uk/footer-links/left/right-to-manage/
http://www.goldsboroughestates.co.uk/how-we-care-for-you/right-to-manage/
http://www.goldsboroughestates.co.uk/buying-a-home/right-to-manage/
http://www.goldsboroughestates.co.uk/what-our-customers-say/right-to-manage/
and I'm afraid they have a different perspective which is they see no canonical problem
Hey ho think I'll just set my head on fire then maybe things will be more clearer

Wow great anser, I'm on to this now & will updat you with how things went

Hey there!
I think I have found what your problem is with you canonical link

In your code you have:
And probably you are somewhere forcing the URls to have a / at the end.
So basically you are confusing browsers and search engine bots, because they now cannot tell which is the real version:
SE enters the page. Then it sees that the right version should be the one WITHOUT a "/" at the end, then that pages has a 301 redirect to the version which HAS a "/" at the end of the URL (but that has a canonical which points out that the preffered version should be ). So it is a non-ending circle.
So if you add a / to the end of your URl, your problem should be solved.
Final thought: Screaming Frog is working well.
I hope this was a solution.
Cheers,
Istvan

520 Error from crawl report with Cloudflare
I am getting a lot of 520 Server Error in crawl reports. I see this is related to Cloudflare. We know 520 is Cloudflare so maybe the Moz team can change this from "unknown" to "Cloudflare 520". Perhaps the Moz team can update the "how to fix" section in the reporting, if they have some possible suggestions on how to avoid seeing these in the report of if there is a real issue that needs to be addressed. At this point I don't know. There must be a solution that Moz can provide like a setting in Cloudflare that will permit the Rogerbot if Cloudflare is blocking it because it does not like its behavior or something. It could be that Rogerbot is crawling my site on a bad day or at a time when we were deploying a massive site change. If I know when my site will be down can I pause Rogerbot? I found this https://developers.cloudflare.com/support/troubleshooting/general-troubleshooting/troubleshooting-crawl-errors/

Trailing slash URLs and canonical links
Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
Technical SEO | | GhillC
However, it sticks to domain names only.
What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
https://www.domain.com
https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!

Subdomain 403 error
Hi Everyone, A crawler from our SEO tool detects a 403 error from a link from our main domain to a a couple of subdomains. However, these subdomains are perfect accessibly. What could be the problem? Is this error caused by the server, the crawlbot or something else? I would love to hear your thoughts.

Does Google read dynamic canonical tags?
Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

URL query strings and canonical tag
Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks

Duplicate canonical URLs in WordPress
Hi everyone, I'm driving myself insane trying to figure this one out and am hoping someone has more technical chops than I do. Here's the situation... I'm getting duplicate canonical tags on my pages and posts, one is inside of the WordPress SEO (plugin) commented section, and the other is elsewhere in the header. I am running the latest version of WordPress 3.1.3 and the Genesis framework. After doing some testing and adding the following filters to my functions.php: <code>remove_action('wp_head', 'genesis_canonical'); remove_action('wp_head', 'rel_canonical');</code> ... what I get is this: With the plugin active + NO "remove action" - duplicate canonical tags

With the plugin disabled + NO "remove action" - a single canonical tag
With the plugin disabled + A "remove action" - no canonical tag I have tried using only one of these remove_actions at a time, and then combining them both. Regardless, as long as I have the plugin active I get duplicate canonical tags. Is this a bug in the plugin, perhaps somehow enabling the canonical functionality of WordPress? Thanks for your help everyone. Robert Dempsey0
