      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.

          Too many dofollow links = penalty?

          Hi. I currently have 150 backlinks, 90% of them are dofollow, while only 10% are nofollow. I recently hit position #10 for my main keyword, but now it is dropped to #16 and a lot of related keywords are gone. So I have a few questions: 1. Was my website penalized for having an unnatural backlink profile (too many dofollow links), or maybe this drop in positions is just a temporary, natural thing? 2. Isn’t it too late for making the backlink profile look more natural by building more nofollow backlinks and making it 50%/50%? Thank you!

          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.

          Dealing with links to your domain that the previous owner set up

          Hey everyone, I rebranded my company at the end of last year from a name that was fairly unique but sounded like I cleaned headstones instead of building websites. I opted for a name that I liked, it reflected my heritage - however it also seems to be quite common. Anyway, I registered the domain name as it was available as the previous owner's company had been wound up. It's only been in the last week or two where I've managed to have a website on that domain and I've been tracking it's progress through Moz, Google & Bing Webmaster tools. Both the webmaster tools are reporting back that my site triggers 404 errors for some specific links. However, I don't have or have never used those links before. I think the previous owner might have created the links before he went bust. My question is in two parts. The first part is how do I find out what websites are linking to me with these broken URL's, and the second is will these 404'ing links affect my SEO? Thanks!

          Do I lose link juice if I have a https site and someone links to me using http instead?

          We have recently launched a https site which is getting some organic links some of which are using https and some are using http. Am I losing link juice on the ones linked using http even though I am redirecting or does Google view them the same way? As most people still use http naturally will it look strange to google if I contact anyone who has given us a link and ask them to change to https?

          Internal Links to Ecommerce Category Pages

          Hello, I read a while back, and I can't find it now, that you want to add internal links to your main category pages. Does that still apply? If so, for a small site (100 products) what is recommended? Thanks

          How do you change the 6 links under your website in Google?

          Hello everyone, I have no idea how to ask this question, so I'm going to give it a shot and hopefully someone can help me!! My company is called Eteach, so when you type in Eteach into Google, we come in the top position (phew!) but there are 6 links that appear underneath it (I've added a picture to show what I mean). How do you change these links?? I don't even know what to call them, so if there is a particular name for these then please let me know! They seem to be an organic rank rather than PPC...but if I'm wrong then do correct me! Thanks! zorIsxH.jpg

          Partners and Customers logo listing and links

          We have just created a program where we list the customers that use our software and a link to their websites on a new "Customers" page. We expect to have upwards of 100 logos with links back to their sites.  I want to be sure this isn't bordering on gray or black hat link building. I think it is okay since they are actual users of our software.  But there is still that slight doubt. Along these same lines, would you recommend adding a nofollow or noindex tag? Thanks for your help.
