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.

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

Rel Noindex Nofollow tag vs meta noindex nofollow
Hi Mozzers I have a bit of thing I was pondering about this morning and would love to hear your opinion on it. So we had a bit of an issue on our client's website in the beginning of the year. I tried to find a way around it by using wild cards in my robots.txt but because different search engines treat wild cards differently it dint work out so well and only some search engines understood what I was trying to do. so here goes, I had a parameter on a big amount of URLs on the website with ?filter being pushed from the database we make use of filters on the site to filter out content for users to find what they are looking for much easier, concluding to database driven ?filter URLs (those ugly &^% URLs we all hate so much*. So what we looking to do is implementing nofollow noindex on all the internal links pointing to it the ?filter parameter URLs, however my SEO sense is telling me that the noindex nofollow should rather be on the individual ?filter parameter URL's metadata robots instead of all the internal links pointing the parameter URLs. Am I right in thinking this way? (reason why we want to put it on the internal links atm is because the of the development company states that they don't have control over the metadata of these database driven parameter URLs) If I am not mistaken noindex nofollow on the internal links could be seen as page rank sculpting where as onpage meta robots noindex nofolow is more of a comand like your robots.txt Anyone tested this before or have some more knowledge on the small detail of noindex nofollow? PS: canonical tags is also not doable at this point because we still in the process of cleaning out all the parameter URLs so +- 70% of the URLs doesn't have an SEO friendly URL yet to be canonicalized to. Would love to hear your thoughts on this. Thanks, Chris Captivate.

Separate domain name for a subdomain?
I just created a subdomain to help our main TLD website. I was wondering if it's smart to create a separate TLD for this subdomain and set up a forward and build links to it. Reason I was thinking about it because it would be easier for people to remember instead of typing in subdomain.maindomain.com. But, I don't want the main website to suffer, since the purpose of creating this subdomain and it's content is to help the main domain. Any inputs on this? Thank you.

Can you block backlinks from another domain
Wondering if this is somehow possible. A site got hacked and created a /data folder with hundreds of .php files that are web pages selling all sorts of stuff. We deleted the /data folder and blocked Google from indexing it. Just noticed in Webmaster Tools that the site has 35,000 backlinks from other sites that got hacked with the same way. Is there a way to block these sites? I am assuming there isn't, but wanted to see if anyone ran into the same problem. It is a wordpress site is that helps.
