      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

          Have 1 performing domain (Monthly - 4M visitor ) now we want to change domain name ( Brand name like SEOMOZ to Moz ). I have general knowledge about domain changing prevention tips like 301 redirection and other thing. My concern is about backlinks and DA. How can I prevent any lose from SEO Point of view. (backlink lose) Do I need to change all backlink form source or redirection is enough to get all reference traffic from that backlinks?

          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

          How do you change the 6 links under your website in Google?

          Hello everyone, I have no idea how to ask this question, so I'm going to give it a shot and hopefully someone can help me!! My company is called Eteach, so when you type in Eteach into Google, we come in the top position (phew!) but there are 6 links that appear underneath it (I've added a picture to show what I mean). How do you change these links?? I don't even know what to call them, so if there is a particular name for these then please let me know! They seem to be an organic rank rather than PPC...but if I'm wrong then do correct me! Thanks! zorIsxH.jpg

          Link Building using Badges

          In light of penguin update, is link building using badges(like "I love SEOMOZ" badge) still considered a white hat tactic? I have read old posts on SEOMOZ blog about this topic and wondering if this method is still effective. Look forward to feedback from MOZers.

          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?

          Penalised by Google - Should I Redirect to a new domain?

          Last month my rankings dropped a couple of pages on Google and am no longer receiving as many visits from Google as I used to. It's coming up to summer which is the time my business naturally picks up yet I can't fix this problem. I have a crazy idea of redirecting my established site onto a new domain in hopes that the penalty would be removed. I have tried removing any manipulative links yet my ranking are not coming back. Anyone had success in redirecting to a new domain?

          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
