Rel Canonical Crawl Notices
-
Hello,
Within the Moz report from the crawl of my site, it shows that I had 89 Rel Canonical notices. I noticed that all the pages on my site have a rel canonical tag back to the same page the tag is on. Specific example from my site is as follows: http://www.automation-intl.com/resistance-welding-equipment has a Rel Canonical tag <link rel="<a class="attribute-value">canonical</a>" href="http://www.automation-intl.com/resistance-welding-equipment" />. Is this self reference harmless and if so why does it create a notice in the crawl?
Thanks in advance.

Thanks Martijn

Just some more information about canonical tags, Matt Cutts has said that self-referring canonical tags like the one you described won't hurt your site. However, Bing said that it could negatively impact rankings, and to not put a tag if it lists its own url. If you are getting the majority of traffic from people using Bing (although it's not likely), you might want to consider removing the canonical tag.
Like Martijn said though, canonical tags are fine when used correctly.

Hi Eric,
Your canonical URL on this page is totally OK like this, as Moz also mentions in the report about the rel canonicals it's just a notice so not a warning or an error. They just give you a notice that this page is containing a canonical tag to make sure you're aware of this!
Hope this answers your question!

Rel=canonical and redirect on same page
Hi Guys, Am I going slightly mad but why would you want to have a redirect and a canonical redirecting back to the same page. For Instance https://handletrade.co.uk/pull-handles/pull-handles-zcs-range/d'-pull-handle-19mm-dia.-19-x-150mm-ss/?tag=Dia.&page=2 and in the source code:- <link href="<a class="attribute-value">https://handletrade.co.uk/d'-pull-handle-19mm-dia.-19-x-150mm-ss/</a>" rel="<a class="attribute-value">canonical</a>" /> Perfect! exactly what it is intended to do. But then this page is 301 redirected tohttps://handletrade.co.uk/pull-handles/pull-handles-zcs-range/d'-pull-handle-19mm-dia.-19-x-150mm-ss/ The site is built in open cart and I think it's the SEO plugin that needs tweaking. Could this cause poor SERP visibility? This is happening across the whole site. Surely the canonical should just point to the proper page and then there is no need for an additional bounce.

Crawl errors: 301 (permanent redirect)
Hi, here are some questions about SEO Crawl Diagnostics. We've recently found out this 301 (permanent redirect) errors in our website and we concluded that the two factors below are the causes. 1. Some of our URLs that has no / at the end is automatically redirected to the same URL but with / at the end. 2. For SEO reasons we have designed our website in a way that when we type in a URL it will automatically redirect to a more SEO friendly URL. For example, if one of the URLs is www.example.com/b1002/, it will automatically redirect to www.example.com/banana juice/. The question is, are these so significant for our SEO and needs to be modified? One of the errors in our blog was having too many on-page links. Is this also a significant error and if so, how many on-page links are recommended from the SEO perspective? Thanks in advance.

What is the best way to use canonical tag
Hi, i have been researching this since yesterday and have looked at this subject many times before but still cannot get my head around it. i done a report on my site which was very useful, i used http://www.juxseo.com for my site www.in2town.co.uk and it brought me some useful information but part of that info was it was telling me that i should have on my home page a canonical tag which would improve my seo. Now i am using sh404sef for my friendly urls and i am using joomla 3.0 and when i approached the makers of the sh404sef to ask about the tag they said i would need to be careful of using it as it could damage my site and my rankings. i have read lots of information but still do not have a clear understanding behind it. can anyone please explain the best way to use this and should i be using where i may have some sort of duplicate page, any help to understand this would be great.

Strange Webmaster Tools Crawl Report
Up until recently I had robots.txt blocking the indexing of my pdf files which are all manuals for products we sell. I changed this last week to allow indexing of those files and now my webmaster tools crawl report is listing all my pdfs as not founds. What is really strange is that Webmaster Tools is listing an incorrect link structure: "domain.com/file.pdf" instead of "domain.com/manuals/file.pdf" Why is google indexing these particular pages incorrectly? My robots.txt has nothing else in it besides a disallow for an entirely different folder on my server and my htaccess is not redirecting anything in regards to my manuals folder either. Even in the case of outside links present in the crawl report supposedly linking to this 404 file when I visit these 3rd party pages they have the correct link structure. Hope someone can help because right now my not founds are up in the 500s and that can't be good 🙂 Thanks is advance!

Magento Canonical Tags
Magento pages have been giving me a lot of trouble with the canonical tags. In some cases duplicate pages are showing up, so I need to add the canonical tag. In other cases I'm getting an error that there are multiple canonical tags per page. How can I get my pages canonized without duplicate tags? It seems like it's either too much or not enough, no matter what I do. Note: this only applies to category and product pages.

Should Canonical URLs be used in Wordpress?
Wordpress offers Canonical URLs in the "All in one SEO" settings. I know that canonical tags for page content will cause the search engine to ignore the content, but I don't understand this setting in Wordpress. The Canonical URLs box for my blog had been checked until a couple weeks ago. I unchecked it (removing the canonical tag) and now I have about 300 duplicate content pages acccording to my SEOMoz reports. It appears that it's just the blog tag in the url now that is causing the confusion. Here's an example of the same url with two tags: http://www.rmtracking.com/blog/tag/aclu/ http://www.rmtracking.com/blog/tag/rfid/ Should I activate the canonical URL setting in Wordpress again. If not, how can I fix this? Your assistance is greatly appreciated. Regards, Brad
