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.

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

Hreflang and canonical tag for new country specific website - different base domain
I have a little different situation compared to most other questions which asks for hreflang and canonical tags for country specific version of websites. This is an SEO related question and I was hoping to get some insight on your recommendations. We have an existing Australian website - say - ausnight.com.au now we want to launch a UK version of this website - the domain is - uknight.co.uk please note, we are not only changing from .com.au to .co.uk.... but the base domain name as well changed - from ausnight to uknight as you can understand, the audience for both websites is different. Both websites has most pages same with same contents.... the questions I have is - Should we put canonical tag on the new website pages? If we don't put canon tag on new website pages, what is the impact on the SEO ranking of current website? I believe we need to put hreflang tag on both websites to tell google that we have another language version (en-au vs en-gb) of the same page. Is this correct?

Landing pages for paid traffic and the use of noindex vs canonical
A client of mine has a lot of differentiated landing pages with only a few changes on each, but with the same intent and goal as the generic version. The generic version of the landing page is included in navigation, sitemap and is indexed on Google. The purpose of the differentiated landing pages is to include the city and some minor changes in the text/imagery to best fit the Adwords text. Other than that, the intent and purpose of the pages are the same as the main / generic page. They are not to be indexed, nor am I trying to have hidden pages linking to the generic and indexed one (I'm not going the blackhat way). So – I want to avoid that the duplicate landing pages are being indexed (obviously), but I'm not sure if I should use noindex (nofollow as well?) or rel=canonical, since these landing pages are localized campaign versions of the generic page with more or less only paid traffic to them. I don't want to be accidentally penalized, but I still need the generic / main page to rank as high as possible... What would be your recommendation on this issue?

Adding hreflang tags - better on each page, or the site map?
Hello, I am wondering if there seems to be a preference for adding hreflang tags (from this article). My client just changed their site from gTLDs to ccTLDs, and a few sites have taken a pretty big traffic hit. One issue is definitely the amount of redirects to the page, but I am also going to work with the developer to add hreflang tags. My question is - is it better to add them to the header of each page, or the site map, or both, or something else? Any other thoughts are appreciated. Our Australia site, which was at least findable using Australia Google before this relaunch, is not showing up, even when you search the company name directly. Thanks!Lauryn

There's a website I'm working with that has a .php extension. All the pages do. What's the best practice to remove the .php extension across all pages?
Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.

Canonical Tag and Affiliate Links
Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!

Best practice to redirects based on visitors' detected language
One of our websites has two languages, English and Italian. The English pages are available at the root level:
Intermediate & Advanced SEO | | Damiano
www.site.com/ English homepage www.site.com/page1
www.site.com/page2 The Italian pages are available under the /it/ level:
www.site.com/it Italian homepage www.site.com/it/pagina1
www.site.com/it/pagina2 When an Italian visitor first visits www.mysit.com we'd like to redirect it to www.site.com/it but we don't know if that would impact search engine spiders (eg GoogleBot) in any way... It would be better to do a Javascript redirect? Or an http 3xx redirect? If so, which of the 3xx redirect should we use? Thank you0
