      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.

          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?

          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?

          Suspicious external links to site have 302 redirects

          Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/

          Are link directories still effective? is there a risk?

          We've contracted a traditional SEO firm, mostly for link building. As part of their plan they want to submit our site to a large list of link directories, and we're not sure if that's a good option. As far as we know, those directories have been ineffective for a long time now, and we're wondering if there is the chance of getting penalized by google. When I asked the agency their opinion about that, they gave me the following answer - Updated and optimized by us - We are partnered with these sites and control quality of these sites. Unique Class C IP address - Links from unique Referring Class C IP plays a very important role in SEO. Powered by high PR backlinks Domain Authority (DA) Score of over 20 These directories are well categorized. So they actually control those directories themselves, which we think is even worse. I'm wondering what does the Moz community think about link directory submission - is there still something to be gained there, is there any risk involved, etc. Thanks!

          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! GaB
