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.

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

Question regarding subdomains and duplicate content
Hey everyone, I have another question regarding duplicate content. We are planning on launching a new sector in our industry to satisfy a niche. Our main site works as a directory with listings with NAP. The new sector that we are launching will be taking all of the content on the main site and duplicating it on a subdomain for the new sector. We still want the subdomain to rank organically, but I'm having struggles between putting a rel=canonical back to main site, or doing a self-referencing canonical, but now I have duplicates. The other idea is to rewrite the content on each listing so that the menu items are still the same, but the listing description is different. Do you think this would be enough differentiating content that it won't be seen as a duplicate? Obviously make this to be part of the main site is the best option, but we can't do that unfortunately. Last question, what are the advantages or disadvantages of doing a subdomain?

Hiding content or links in responsive design
Hi, I found a lot of information about responsive design and SEO, mostly theories no real experiment and I'd like to find a clear answer if someone tested that. Google says:

Sites that use responsive web design, i.e. sites that serve all devices on the same set of URLs, with each URL serving the same HTML to all devices and using just CSS to change how the page is rendered on the device
https://developers.google.com/webmasters/smartphone-sites/details For usability reasons sometimes you need to hide content or links completely (not accessible at all by the visitor) on your page for small resolutions (mobile) using CSS ("visibility:hidden" or "display:none") Is this counted as hidden content and could penalize your site or not? What do you guys do when you create responsive design websites? Thanks! GaB0 -
Disavow - Broken links
I have a client who dealt with an SEO that created not great links for their site. http://www.golfamigos.co.uk/ When I drilled down in opensiteexplorer there are quite a few links where the sites do not exist anymore - so I thought I could test out Disavow out on them .. maybe just about 6 - then we are building good quality links to try and tackle this problem with a more positive approach. I just wondered what the consensus was?

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.
