Sub Domain rel=canonical to Main Domain
-
Just a quick one, i have the following example scenario.
Main Domain: http://www.test.com
Sub Domain: http://sub.test.com
What I am wondering is I can add onto the sub domain a rel=canonical to the main domain. I dont want to de-index the whole sub domain just a few pages are duplicated from the main site.
Is it easier to de-index the individual sub domain pages or add the rel=canonical back to the main domain.
Much appreciated
Joseph

Canonicalizing http://sub.test.com to http://www.test.com will tell Google that those two individual pages are the same and it should only index http://www.test.com--it won't affect other pages on the subdomain.
If you only have a few subdomain pages that are duplicates of root domain pages, you can just use canonicals to indicate which pages you want indexed. You won't need to noindex the duplicate ones--they will fall out of Google's index naturally once Google sees which are the preferred, canonical ones.

Hi there,
The Rel=canonical will not de-index those pages.
To de-index, add a rel=robots with a noindex tag. And also add the rel=canonical or just redirect 301 the page. Of course, do it to those selected pages only.
Hope it helps.
GR.

Do links from subdomains pass the authority and link juice of main domain ?
Hi, There is a subdomain with a root domain's DA 90. I can earn a backlink from that subdomain. This subdomain is fresh with no traffic yet. Do I get the ranking boost and authority from the subdomain? Example: I can earn a do-follow link from **https://what-is-crm.netlify.app/ **but not from https://netlify.app

Sitewide nav linking from subdomain to main domain
I'm working on a site that was heavily impacted by the September core update. You can see in the attached image the overall downturn in organic in 2019 with a larger hit in September bringing Google Organic traffic down around 50%. There are many concerning incoming links from 50-100 obviously spammy porn-related websites to just plain old unnatural links. There was no effort to purchase any links so it's unclear how these are created. There are also 1,000s of incoming external links (most without no-follow and similar/same anchor text) from yellowpages.com. I'm trying to get this fixed with them and have added it to the disavow in the meantime. I'm focusing on internal links as well with a more specific question: If I have a sitewide header on a blog located at blog.domain.com that has links to various sections on domain.com without no-follow tags, is this a possible source of the traffic drops and algorithm impact? The header with these links is on every page of the blog on the previously mentioned subdomain. **More generally, any advice as to how to turn this around? ** The website is in the travel vertical. 90BJKyc

Let me explain my confusion:
I’ve checked backlink profile of a website. He is not using his main domain while doing comment backlink. He put his another domain while doing comment backlink. The another domain redirect to the main domain. Why he use another domain while doing comment backlink?
Is it helpful to get better rank on Google? For example: My Main Domain = solutionfall.com
Another Domain= xyz.com (It redirect to solutionfall.com)
He just uses xyz.com while doing comment backlink. Thank You so much1 -

Penalised by Google - Should I Redirect to a new domain?
Last month my rankings dropped a couple of pages on Google and am no longer receiving as many visits from Google as I used to. It's coming up to summer which is the time my business naturally picks up yet I can't fix this problem. I have a crazy idea of redirecting my established site onto a new domain in hopes that the penalty would be removed. I have tried removing any manipulative links yet my ranking are not coming back. Anyone had success in redirecting to a new domain?
