      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

          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.

          Old subdomains - what to do SEO-wise?

          Hello, I wanted the community's advice on how to handle old subdomains. We have https://www.yoursite.org. We also have two subdomains directly related to the main website: https://www.archive.yoursite.org and https://www.blog.yoursite.org. As these pages are not actively updated, they are triggering lots and lots of errors in the site crawl (missing meta descriptions, and much much more). We do not have particular intentions of keeping them up-to-date in terms of SEO. What do you guys think is the best option of handling these? I considered de-indexing, but content of these page is still relevant and may be useful - yet it is not up to date and it will never be anymore. Many thanks in advance.

          Sub Domain rel=canonical to Main Domain

          Just a quick one, i have the following example scenario. Main Domain: http://www.test.com Sub Domain: http://sub.test.com What I am wondering is I can add onto the sub domain a rel=canonical to the main domain. I dont want to de-index the whole sub domain just a few pages are duplicated from the main site. Is it easier to de-index the individual sub domain pages or add the rel=canonical back to the main domain. Much appreciated Joseph

          Are All Paid Links and Submissions Bad?

          My company was recently approached by a website dedicated to delivering information and insights about our industry. They asked us if we wanted to pay for a "company profile" where they would summarize our company, add a followed link to our site, and promote a giveaway for us. This website is very authoritative and definitely provides helpful use to its audience. How can this website get away with paid submissions like this? Doesn't that go against everything Google preaches? If I were to pay for a profile with them, would I request for a "nofollow" link back to my site?

          How to 301 redirect from old domain and their pages to new domain and pages?

          Hi i am a real newbie to this and i hope for a guide on how to do this. I seen a few moz post and is quiet confusing hopefully somebody able to explain it in layman terms to me. I would like to  301 redirect this way, both website contain the same niche. oldwebsite.com > newwebsite.com and also its pages..... oldwebsite.com/test >newwebsite.com/test So my question here is i would like to host my old domain and its pages in my new website hosting in order to redirect to my new domain and its pages how do i do that? would my previous page link overwrite my new page link? or it add on the juice link? Do i need to host the whole old domain website into my new hosting in order to redirect the old pages? really confusing here, thanks!

          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/

          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?
