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!

Duplicate, submitted URL not selected as canonical
Hi all, A number of our pages have dropped out of search rankings. It seems they are being marked as "Duplicate, submitted URL not selected as canonical" However, the page Google is choosing as the canonical is totally different - different headings, titles, metadata, content on the page. We are completely mystified as to why this is happening. If anyone can shed any light, it would be hugely appreciated! Example URL is this one:

Canonical Tags Before HTTPS MIgration
Hi Guys I previously asked a question that was helpfully answered on this forum, but I have just one last question to ask. I'm migrating a site tomorrow from http to https. My one question is that it was mentioned that I may need to "add canonical tags to the http pages, pointing to their https equivalent prior to putting the server level redirect in place. This is to ensure that you won't be causing yourself issues if the redirect fails for any reason." This is an e-commerce site with a number of links, is there a quick way of doing this? Many Thanks

Canonical tag or 301
Hi, Our crawl report is showing duplicate content. some of the report I am clear about what to do but on others I am not. Some of the duplicate content arises with a 'theme=default' on the end of the URL. Is this version of a page necessary for people to see when they visit the site (like a theme=print page is) in which case I think we should use a canonical tag, or is it not necessary in which case we should use a 301? Thanks

What does the Google Crawler see when crawling this page?
If you look at this page http://www.rockymountainatvmc.com/t/49/61/185/730/Batteries. You will see we have a vehicle filter on it. Right now you only see a picture of a battery and some bad text that needs to be updated ( We just hired a copywriter!). Our question is when google crawls this site will thy just see this or will they see all the products that appear after you pick a "machine type" "make" "model" and "year" Any help would be great. Right now we think it just sees this main page how we have set things up; however, we know that the crawler is also crawling some ajax. We just want to be sure of things.

Rel = author display issue
I want to enter some products as blog posts. I don't want users to see the post info, but do want SE's to see rel="author". I can do this by setting display to "none" in a CSS style. The post info does not appear in the browser but is still in the page source. Will search engines be able to see the post info?

Canonical tags
Hi there, I have just noticed that SEOmoz picked up some duplicates links that I would like to resolve but not sure how. For example, the "Finding work in the arts" article has two links: http://www.creative-choices.co.uk/develop-your-career/article/finding-work-in-the-arts http://www.creative-choices.co.uk/develop-your-career/article/finding-work-in-the-arts?utm_source=Website&utm_medium=Website&utm_content=Finding+work+in+the+arts&utm_campaign=Footer+Links Both links can be found on this page http://www.creative-choices.co.uk/industry-news-views/article/what-employers-are-looking-for (see attachment). Would automatically generated canonical tags by the CMS solve this issue? rmxiP

Should i use NoIndex, Follow & Rel=Canonical Tag In One Page?
I am having pagination problem with one of my clients site , So I am deciding to use noindex, follow tag for the Page 2,3,4 etc for not to have duplicated content issue, Because obviously SEOMoz Crawl Diagnostics showing me lot of duplicate page contents. And past 2 days i was in constant battle whether to use noindex, follow tag or rel=canonical tag for the Page 2,3,4 and after going through all the Q&A,None of them gives me crystal clear answer. So i thought "Why can't i use 2 of them together in one page"? Because I think (correct me if i am wrong) 1.noindex, follow is old and traditional way to battle with dup contents

2.rel=canonical is new way to battle with dup contents Reason to use 2 of them together is: Bot finds to the non-canonical page first and looks at the tag nofollow,index and he knows not to index that page,meantime he finds out that canonical url is something something according to the url given in the tag,NO? Help Please???0
