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
-
Any subdomain links shared won't contribute to your main site's link authority or ranking in search results because they are (basically) considered two sites, they just have a lot of links between them.

Spam Score & Redirecting Inbound Links
Hi, I recently downloaded a spreadsheet of inbound links to my client sites and am trying to 301 redirect the ones that are formatted incorrectly or just bad links in general (they all link to the site domain, but they used to have differently formatted urls on their old site, or the link URL in general has strange stuff on it). My question is, should I even bother redirecting these links if their spam score is a little high (i.e. 20-40%)? it already links to the existing domain, just with a differently formatted URL. I just want to make sure it goes to a valid URL on the site, but I don't want to redirect to a valid URL if it's going to harm the client's SEO. Also not sure what to do about the links with the --% spam score. I really appreciate any input as I don't have a lot of experience with how to deal with spammy links.

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.

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

How to 301 redirect from old domain and their pages to new domain and pages?
Hi i am a real newbie to this and i hope for a guide on how to do this. I seen a few moz post and is quiet confusing hopefully somebody able to explain it in layman terms to me. 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!

Disavow links leading to 404
Looking at the link profile anchor text of a site i'm working on new links keep popping up in the reports with let's say very distasteful anchor text. These links are obviously spam and link to old forum pages for the site that doesn't exist any more, so the majority seem to trigger the 404 page. I understand that the 404 page (404 header response) does not flow any link power, or damage, but given the nature and volume of the sites linking to the "domain" would it be a good idea to completely disassociate and disavow these domains?

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?

Site being targeted by hardcore porn links
We noticed recently a huge amount of referral traffic coming to a client's site from various hard cord porn sites. One of the sites has become the 4th largest referrer and there are maybe 20 other sites sending traffic. I did a Whois look up on some of the sites and they're all registered to various people & companies, most of them are pretty shady looking. I don't know if the sites have been hacked or are deliberately sending traffic to my client's site, but it's obviously a concern. The client's site was compromised a few months ago and had a bunch of spam links inserted into the homepage code. Has anyone else seen this before? Any ideas why someone would do this, what the risks are and how we fix it? All help & suggestions greatly appreciated, many thanks in advance. MB.

Would linking out to a gambling/casino site, harm my site and the other sites it links out to?
I have been emailed asking if I sell links on one of my sites. The person wants to link out to slotsofvegas[dot]com or similar. Should I be concerned about linking out to this and does it reduce the link value to any of the other sites that the site links out to? Thanks, Mark
