Is it best practice to have a canonical tags on all pages
-
The website I'm working on has no canonical tags. There is duplicate content so rel=canonicals need adding to certain pages but is it best practice to have a tag on every page ?
-
ColesNathan,
Have you seen what Google has to say about canonicals? https://support.google.com/webmasters/answer/139066?hl=en
You might find it helpful. They list reasons why you might want to use a canonical tag including those identified above and a few others, for example, for letting Google know your priorities when it comes to crawl budget and SERP display.
Canonicals can also help undermine plagiarism. If scrapers leave your self-referencing canonical intact, it will tell Google you are the originator of that content and consolidate link signals into your URL.
-
Correct, I would usually advise adding in a self-referencing canonical tag to make it easier for audits and search engines to understand what the actual content is on the page.
-
Hi, thanks for getting back to me. Ok so you don't need a canonical on every page unless its required.
However, for tracking purposes it is good practice to have one set up on all pages?
Have I got that right ?

Hi there!
It is a best practice as long as you have a CMS or any system that allows you to control them. In the case of Wordpress with YOAST it is pretty easy to set up.
Why would you want a canonical on every page? This is useful when you have different campaigns and you use url parameters for tracking (the common _utm from Google analytics), and that is correctly taken care of with wordpress+YOAST.If you see that you dont need canonicals on any page, then dont use it. Just be sure that when generating parameters o duplicate content, there is a canonical.
Hope i´ve helped.
Best luck.

Would You Redirect a Page if the Parent Page was Redirected?
Hi everyone! Let's use this as an example URL: https://www.example.com/marvel/avengers/hulk/ We have done a 301 redirect for the "Avengers" page to another page on the site. Sibling pages of the "Hulk" page live off "marvel" now (ex: /marvel/thor/ and /marvel/iron-man/). Is there any benefit in doing a 301 for the "Hulk" page to live at /marvel/hulk/ like it's sibling pages? Is there any harm long-term in leaving the "Hulk" page under a permanently redirected page? Thank you! Matt

Spammy page with canonical reference to my website
A potentially spammy website http://www.rofof.com/ has included a rel canonical tag pointing to my website. They've included the tag on thousands of pages on their website. Furthermore http://www.rofof.com/ appears to have backlinks from thousands of other low-value domains For example www.kazamiza.com/vb/kazamiza242122/, along with thousands of other pages on thousands of other domains all link to pages on rofof.com, and the pages they link to on rofof.com are all canonicalized to a page on my site. If Google does respect the canonical tag on rofof.com and treats it as part of my website then the thousands of spammy links that point to rofof.com could be considered as pointing to my website. I'm trying to contact the owner of www.rofof.com hoping to have the canonical tag removed from their website. In the meantime, I've disavowed the www.rofof.com, the site that has canonical tag. Will that have any effect though? Will disavow eliminate the effect of a rel canonical tag on the disavowed domain or does it only affect links on the disavowed website? If it only affects links then should I attempt to disavow all the pages that link to rofof.com? Thanks for reading. I really appreciate any insight you folks can offer.

Htaccess - Redirecting TAG or Category pages
Hello Fellow Moz's, We have an issue redirecting some /TAG and /Category pages to inner pages. As an example we use: RedirectMatch 301 /category/Sample-Category(.*) https://OurDomain.com.au/New-Page//$1 That works well. The issue is we have other categories and tags that are named similar to /Sample-Category As an example, if we try to redirect /Sample-Category-1 to /New-Page-1 - it will not work, and redirects to /New-Page I assume this is because /Sample-Category is already being redirected, so anything after /Sample-Category like -1 or -2 or -3 etc, will not be recognized. Anyone know of a workaround?

Image URLs - best practice
Hi - I'm assuming image URL best practice follows same principles as non image URLs (not too many files and so on) - I notice alot of web devs putting photos in subdomains, so wonder if I'm missing something (I usually avoid subdomains like the plague)!

Duplicate Title tags even with rel=canonical
Hello, We were having duplicate content in our blog (a replica of each post automatically was done by the CMS), until we recently implemented a rel=canonical tag to all the duplicate posts (some 5 weeks ago). So far, no duplicate content were been found, but we are still getting duplicate title tags, though the rel=canonical is present. Any idea why is this the case and what can we do to solve it? Thanks in advance for your help. Tej Luchmun

Should you use a canonical tag on translated content in a multi-language country?
A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
Intermediate & Advanced SEO | | Zanox
At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???0 -
How does a canonical work and is it necessary to also have a no index, follow tag in place?
Across our site, we have canonical tags in place for URLs that contain duplicate content and for URLs without a trailing slash since we are using URLs WITH a trailing slash for all URLs across our site. We also recently added a no index, follow tag to all non-canonical URLs since we noticed a high number of duplicate content URLs in Google Webmaster Tools. The first part of my question is: How does a canonical work? Does the robot read the canonical and immediately go to the canonical URL or does it continue to read past the canonical tag and get to the no index, follow tag if there is one present? The second part of my question is: Is it necessary to have both a canonical tag and no index, follow tag in place? Or should the canonical tag be sufficient to avoid duplicate content? And lastly, if both a canonical tag and no index, follow tag are in place, should they be in a specific order? Canonical tag first then no index, follow tag second or no index, follow tag first then canonical tag second? I would appreciate any insight you can give. Thank you!
