This question already has an answer here:
I have a question regarding canonical URLs. My problem is that I think I understand canonical URLs but I am also not entirely sure.
I have a website that is starting to score really well in Google. So that's fine. However I want to create some promo sub-pages. And using canonical URLs is good. But I am afraid that if my logic has some errors I might screw up that what I've obtained and worked very hard for to obtain.
So here is my situation.
I have a website : www.example.com
We have several pages on this website
Now we would like to add some promo landingpages at promotion.example.com This page should have the following pages
- promotion.example.com/about-us.html (duplicate from the main domain)
- promotion.example.com/our-priceplan.html (* new priceplan, just for this promotion *)
- promotion.example.com/contact-us.html (*duplicate from the main domain *)
Are duplicates from the original ones set in the main domain example.com, I understand that I should set for the first :
<link rel="canonical" href="https://example.com/about-us.html" />
<link rel="canonical" href="https://example.com/contact-us.html" />
for the second.
My question is.. Did I understand this correctly to avoid any penalty. There is a lot depending on it for me. Hence my question.
Thanks in advance.
