Moz Q&A is closed.
After more than 13 years, and tens of thousands of questions, Moz Q&A closed on 12th December 2024. Whilst we’re not completely removing the content - many posts will still be possible to view - we have locked both new posts and new replies. More details here.
Would you disavow links that have a Moz Spam score of 5?
-
As the question suggests...
-
Spam score can be a useful adjunct when helping you decide which links to disavow, but you should never make a disavow decision based on spam score alone.
The disavow tool should be used by site owners who have a huge problem with unnatural links. If you know that this link is one that you yourself made for SEO purposes alone and that you have lots of links like this, then yes, you should probably disavow it.
But otherwise I wouldn't be too concerned.

No problem. I've expanded upon the original answer to clarify what the Spam Score references. This may be useful. (Read from UPDATE: down).
I hope that helps.

Thank you!

Nope. Moz suggest you don't get too excited about anything below an 8 and even then proceed with caution. Disavowing links is not usually something Google would expect you to need to get involved in, unless you are dealing with thousands of links.
"This [Disavow backlinks] is an advanced feature and should only be used with caution. If used incorrectly, this feature can potentially harm your site’s performance in Google’s search results. We recommend that you disavow backlinks only if you believe you have a considerable number of spammy, artificial, or low-quality links pointing to your site, and if you are confident that the links are causing issues for you. In most cases, Google can assess which links to trust without additional guidance, so most normal or typical sites will not need to use this tool."
From: https://support.google.com/webmasters/answer/2648487
EGOL (who is wise in such matters) references this in a recent Q and A post and says he has never disavowed a single backlink, I've only ever done so once, in a panic and don't see myself doing so again. Much better to concentrate your efforts into countering the spammy links with great content.
UPDATE: Another thing to consider, if you click on Open Site Explorer > Spam Analysis - You'll see a number of these flags are issues you can fix without disavowing links. More often than not, you can fix a few of those. And remember, the Spam Score is not some hard and fast rule that Google follows; they are just a set of signals that Moz believe to have a correlation to Google penalties.

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.

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

Pinging Links
Interested to know if anybody still uses the strategy of pinging links to make sure they get indexed, there are a number of sites out there which offer it. Is it considered dangerous/spamy?

How/Why do I have so many Spam backlinks?
I was looking in GWT yesterday and found we have several thousand "spam" backlinks...I am curious why this happens and how this happens? There are some links from websites/domains that are not mine that appear to be spam. However, we own a large group of domains and have noticed some of the links are coming from 2 of those sites/domains we own to my main site. The sites/domains are not active, we just own them. I am wondering how someone could access these domains that are not active and create spammy backlinks to my main website? (They created about 20,000 links). Thanks.

Footer Link in International Parent Company Websites Causing Penalty?
Still waiting to look at the analytics for the timeframe, but we do know that the top keyword dropped on or about April 23, 2012 from the #1 ranking in Google - something they had held for years, and traffic dropped over 15% that month and further slips since. Just looked at Google Webmaster Tools and see over 2.3MM backlinks from "sister" compainies from their footers. One has over 700,000, the rest about 50,000 on average and all going to the home page, and all using the same anchor text, which is both a branded keyword, as well as a generic keyword, the same one they ranked #1 for. They are all "nofollows" but we are trying to confirm if the nofollow was before or after they got hit, but regardless, Google has found them. To also add, most of sites are from their international sites, so .de, .pl, .es, .nl and other Eurpean country extensions. Of course based on this, I would assume the footer links and timing, was result of the Penguin update and spam. The one issue, is that the other US "sister" companies listed in the same footer, did not see a drop, in fact some had increase traffic. And one of them has the same issue with the brand name, where it is both a brand name and a generic keyword. The only note that I will make about any of the other domains is that they do not drive the traffic this one used to. There is at least a 100,000+ visitor difference among the main site, and this additional sister sites also listed in the footer. I think I'm on the right track with the footer links, even though the other sites that have the same footer links do not seem to be suffering as much, but wanted to see if anyone else had a different opinion or theory. Thanks!

Does anyone have any suggestions on removing spammy links?
I have some clients that recently got hit by "Penguin" they have several less than desireable backlinks that could be the issue? Does anyone have any suggestions on getting these removed? What are the odds that a webmaster on these spammy sites are going to remove them, and is it worth the time and effort?

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
