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.

Does google sandbox aged domains too?
Hello, i have a question. Recently i bought a domain from godaddy auction which is 23 years old and have DA 37 PA 34 Before bidding i check out the domain on google using this query to make sure if pages of this website are showing or not (site:mydomain.com) only home page was indexed on google. Further i check the domain on archive web the domain was last active in 2015. And then it parked for long about 4 years. So now my question does google consider these type of domain as new or will sandboxed them if i try to rebuild them and rank for other niche keywords ? Because its been 4 weeks i have been building links to my domain send several profile and social signals to my domain. My post is indexed on google but not showing in any google serp result.

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 -

I would like to 301 redirect this way, both website contain the same niche. oldwebsite.com > newwebsite.com and also its pages..... oldwebsite.com/test >newwebsite.com/test So my question here is i would like to host my old domain and its pages in my new website hosting in order to redirect to my new domain and its pages how do i do that? would my previous page link overwrite my new page link? or it add on the juice link? Do i need to host the whole old domain website into my new hosting in order to redirect the old pages? really confusing here, thanks!

Why does expired domains still work for SEO?
Hi everyone I’ve been doing an experiment during more than 1 year to try to see if its possible to buy expired domains. I know its considered black hat, but like I said, I wanted to experiment, that is what SEO is about. What I did was to buy domains that just expired, immediately added content on a WP setup, filled it with relevant content to the expired domain and then started building links to other relevant sites from these domains.( Here is a pretty good post on how to do, and I did it in a similar way. http://searchenginewatch.com/article/2297718/How-to-Build-Links-Using-Expired-Domains ) This is nothing new and SEO:s has been doing it for along time. There is a lot of rumors around the SEO world that the domains becomes worthless after they expire. But after trying it out during more than 1 year and with about 50 different expired domains I can conclude that it DOES work, 100% of the time. Some of the domains are of course better than others, but I cannot see any signs of the expired domains or the sites i link to has been punished by Google. The sites im liking to ranks great ONLY with those links 🙂 So to the question: WHY does Google allow this? They should be able to see that a domain has been expired right? And if its expired, why dont they just “delete” all the links to that domain after the expiry date? Google is well aware of this problem so what is stopping them? Is there any one here that know how this works technically?

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.
