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.

Hi Shawn,
1, if you spot clearly spammy and unnatural links.. go ahead and disavow them. Keep in mind that there is the possibility to disavow entire domains. Here for more information about it. Disavow backlinks - Google Search Console.
2, No, sitewide links from a blog or in any part of your own website won't be a cause of penalty like this one. Google is able to recognize sitewide links a few years back. I wouldn't worry about that.
3, There are many areas to focus after an organic penalty. I'd suggest trying to understand which queries and URLs are the ones losing traffic and rankings, mostly from Google Search Console. Then, analyze what's going on with the User Experience and Site Speed, comparing your website with the ones that outrank you. And, last but not least, content! Check your content whether is the one that should be answering user's queries.
Hope it helps,
Best luck.
Gaston

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

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?

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:
White Hat / Black Hat SEO | | NurunMTL
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 -
Off-page SEO and link building
Hi everyone! I work for a marketing company; for one of our clients' sites, we are working with an independent SEO consultant for on-page help (it's a large site) as well as off-page SEO. Following a meeting with the consultant, I had a few red flags with his off-page practices – however, I'm not sure if I'm just inexperienced and this is just "how it works" or if we should shy away from these methods. He plans to: guest blog do press release marketing comment on blogs He does not plan to consult with us in advance regarding the content that is produced, or where it is posted. In addition, he doesn't plan on producing a report of what was posted where. When I asked about these things, he told me they haven't encountered any problems before. I'm not saying it was spam-my, but I'm more not sure if these methods are leaning in the direction of "growing out of date," or the direction of "black-hat, run away, dude." Any thoughts on this would be crazy appreciated! Thanks, Casey

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?

Separate domain name for a subdomain?
I just created a subdomain to help our main TLD website. I was wondering if it's smart to create a separate TLD for this subdomain and set up a forward and build links to it. Reason I was thinking about it because it would be easier for people to remember instead of typing in subdomain.maindomain.com. But, I don't want the main website to suffer, since the purpose of creating this subdomain and it's content is to help the main domain. Any inputs on this? Thank you.

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
