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

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/

Should I Do a Social Bookmarking Campaign and a Tier 2 Linking?
I don't see anything bad in manually creating links on different (about 50) social bookmarking services. Is this method labeled as White Hat? I was wondering if it would be fine to create Tier 2 linking (probably blog comments) for indexing of the social bookmarking links? Please share your thoughts on the topic.

Subdomains vs. Subfolders Wordpress Multisite
I am in the process redesigning my organization's website using wordpress multisite. I am currently planning on creating subdomains for each of the locations, as I thought that having a keyword saturated domain name would provide the best rankings. So the Omaha office would look like this: omaha.example.com Would it be better to go with example.com/omaha? Things to consider: Google adwords is currently a huge source of our traffic. Despite having very good organic rankings, we receive most of our traffic from pay-per-click sources. The "display URL" has dramatic effect on our CTR, so I want to avoid subfolders if possible. (example OmahaEmergencyDental.com receives far more click thru's than EmergencyDental.com) Each location currently has it's own domain and website (omahaemergencydental.com) these sites/pages have been in place for several years Thanks in advance!

Deny visitors by referrer in .htaccess to clean up spammy links?
I want to lead off by saying that I do not recommend trying this. My gut tells me that this is a bad idea, but I want to start a conversation about why. Since penguin a few weeks ago, one of the most common topics of conversation in almost every SEO/Webmaster forum is "how to remove spammy links". As Ryan Kent pointed out, it is almost impossible to remove all of these links, as these webmasters and previous link builders rarely respond. This is particularly concerning given that he also points out that Google is very adamant that ALL of these links are removed. After a handful of sleepless nights and some research, I found out that you can block traffic from specific referring sites using your.htaccess file. My thinking is that by blocking traffic from the domains with the spammy links, you could prevent Google from crawling from those sites to yours, thus indicating that you do not want to take credit for the link. I think there are two parts to the conversation... Would this work? Google would still see the link on the offending domain, but by blocking that domain are you preventing any strength or penalty associated with that domain from impacting your site? If for whatever reason this would nto work, would a tweak in the algorithm by Google to allow this practice be beneficial to both Google and the SEO community? This would certainly save those of us tasked with cleaning up previous work by shoddy link builders a lot of time and allow us to focus on what Google wants in creating high quality sites. Thoughts?

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.
