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.

Does having alot of pages with noindex and nofollow tags affect rankings?
We are an e-commerce marketplace at for alternative fashion and home decor. We have over 1000+ stores on the marketplace. Early this year, we switched the website from HTTP to HTTPS in March 2018 and also added noindex and nofollow tags to the store about page and store policies (mostly boilerplate content) Our traffic dropped by 45% and we have since not recovered. We have done I am wondering could these tags be affecting our rankings?

Category Page as Shopping Aggregator Page
Hi, I have been reviewing the info from Google on structured data for products and started to ponder.
Intermediate & Advanced SEO | | Alexcox6
https://developers.google.com/search/docs/data-types/products Here is the scenario.
You have a Category Page and it lists 8 products, each products shows an image, price and review rating. As the individual products pages are already marked up they display Rich Snippets in the serps.
I wonder how do we get the rich snippets for the category page. Now Google suggest a markup for shopping aggregator pages that lists a single product, along with information about different sellers offering that product but nothing for categories. My ponder is this, Can we use the shopping aggregator markup for category pages to achieve the coveted rich results (from and to price, average reviews)? Keen to hear from anyone who has had any thoughts on the matter or had already tried this.0 -
Splitting One Site Into Two Sites Best Practices Needed
Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter. The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

URL Rewriting Best Practices
Hey Moz! I’m getting ready to implement URL rewrites on my website to improve site structure/URL readability. More specifically I want to: Improve our website structure by removing redundant directories. Replace underscores with dashes and remove file extensions for our URLs. Please see my example below: Old structure: http://www.widgets.com/widgets/commercial-widgets/small_blue_widget.htm New structure: https://www.widgets.com/commercial-widgets/small-blue-widget I've read several URL rewriting guides online, all of which seem to provide similar but overall different methods to do this. I'm looking for what's considered best practices to implement these rewrites. From what I understand, the most common method is to implement rewrites in our .htaccess file using mod_rewrite (which will find the old URLs and rewrite them according to the rewrites I implement). One question I can't seem to find a definitive answer to is when I implement the rewrite to remove file extensions/replace underscores with dashes in our URLs, do the webpage file names need to be edited to the new format? From what I understand the webpage file names must remain the same for the rewrites in the .htaccess to work. However, our internal links (including canonical links) must be changed to the new URL format. Can anyone shed light on this? Also, I'm aware that implementing URL rewriting improperly could negatively affect our SERP rankings. If I redirect our old website directory structure to our new structure using this rewrite, are my bases covered in regards to having the proper 301 redirects in place to not affect our rankings negatively? Please offer any advice/reliable guides to handle this properly. Thanks in advance!

How do I get rel='canonical' to eliminate the trailing slash on my home page??
I have been searching high and low. Please help if you can, and thank you if you spend the time reading this. I think this issue may be affecting most pages. SUMMARY: I want to eliminate the trailing slash that is appended to my website. SPECIFIC ISSUE: I want www.threewaystoharems.com to showing up to users and search engines without the trailing slash but try as I might it shows up like www.threewaystoharems.com/ which is the canonical link. WHY? and I'm concerned my back-links to the link without the trailing slash will not be recognized but most people are going to backlink me without a trailing slash. I don't want to loose linkjuice from the people and the search engines not being in consensus about what my page address is. THINGS I"VE TRIED: (1) I've gone in my wordpress settings under permalinks and tried to specify no trailing slash. I can do this here but not for the home page. (2) I've tried using the SEO by yoast to set the canonical page. This would work if I had a static front page, but my front page is of blog posts and so there is no advanced page settings to set the canonical tag. (3) I'd like to just find the source code of the home page, but because it is CSS, I don't know where to find the reference. I have gone into the css files of my wordpress theme looking in header and index and everywhere else looking for a specification of what the canonical page is. I am not able to find it. I'm thinking it is actually specified in the .htaccess file. (4) Went into cpanel file manager looking for files that contain Canonical. I only found a file called canonical.php . the only thing that seemed like it was worth changing was changing line 139 from $redirect_url = home_url('/'); to $redirect_url = home_url(''); nothing happened. I'm thinking it is actually specified in the .htaccess file. (5) I have gone through the .htaccess file and put thes 4 lines at the top (didn't redirect or create the proper canonical link) and then at the bottom of the file (also didn't redirect or create the proper canonical link) : RewriteEngine on

Best practice for duplicate website content: same root domain name but different extension
Hi there I have a new client who has two websites: http://www.bayofislandsteambuilding.co.nz
Intermediate & Advanced SEO | | turnbullholdingsltd
http://www.bayofislandsteambuilding.org.nz They are the same in every regard apart from the domain extension (.co.nz & .org.nz) which is likely to be causing them issues with Google ranking given the huge amount of duplicate content. What is the best practice approach to fixing this? Normally, if I was starting from scratch, I would set one of the extensions as an alias which redirects to the main domain. Thanks in advance.

Domain Name Change - Best Practices?
Good day guys, We got a restaurant that is changing its name and domain. However they are keeping the same server location, same content and same pages (we are just changing the logo on the website). It just has to go a new domain. We don't want to lose the value of the current site, and we want to avoid any duplicate penalties. Could you please advise of the best practices of doing a domain name change? Thank you.
