            Thanks for quoting me in the answer. I didn't realize the original answer was so popular, either. Glad it's one that's easily understood.

                To lift a quote from Keri Morgret in this thread from a few years ago:

                "It refers to the part of the IP address that's different. The same class C address means something has the same third octect in the address. In the following, the first three IPs are in the same class C, and the fourth address is not.

                192.168.1.1
                192.168.1.2
                192.168.1.3
                192.168.100.4

                ...it's a hint to Google that the sites are all related to each other and on the same server, and that the links may not be very natural since there is the good possibility that the same person set them up."

                  How Long Do The Link Tracking Lists Take To Update?

                  Hi, How long do the link tracking lists take to update? It's been over a week and each is still showing a red cross. The reason I created it was because I migrated to a new domain name and Moz is still showing the backlinks on the old property and not the new (the domain swap happened in December 2020). I can see that Ahrefs has picked up all of the links - Both new and redirected - but Moz has not. When will this be reflected in Moz as it has already been over three months? Is there a reason for the above questions? I appreciate any response here. 🙂

                  Competitor getting External Links from search.aol.com

                  Recently, I noticed that one of the competitors I track within my Moz campaign received about 12 new inbound  links. As a result, there DA jumped about 10 points. I reviewed these new external links and was surprised to see that they are all "search.aol.com/aol/search?query= ..." with Link Anchor Text that is good for the industry we compete in. Can anyone tell me why these are being counted as "Inbound Links". It just doesn't seem right. Is this some sort of black hat seo tactic?

                  Whether or not to remove a link from a website with high spam score on Open Site Explorer

                  Hello Moz! I just subscribed for your Moz Pro program. Amazing stuff! On open site explorer, I found a number of links to my site from a page called with a very high page authority and high domain authority, but also a high spam score (8 or 9, one with a 10). I say multiple spam scores, because it's strange, there are what appears variations of the same url, and each one is considered a link.  For instance, there's an abc.linkstomysite.com and xyz.linktomysite.com, and 123.linktomysite.com... there are about 15 of these (all with the spam scores mentioned above)! This must have been some old SEO work done I payed for back in the prehistoric SEO days. However, my fear is the following: Removing these links, and then losing some potentially strong link juice.  I don't have many high DA or PA links to my site, and these are some major ones. The domain in question "linktomysite.com", when entered into OSE, only has a spam score of 4, and it has a domain authority of 45 and page authority of 37.  My site has a spam score of 2 and no messages from google regarding a penalty, but an overall reduction in google traffic over the years (just keeps slowly dropping... as if a weight is pulling me down?) What do you think, should I leave, or remove?  The linkstomysite page is just a LONG page full of links, with short descriptions, nothing of value, but with a an old domain age (relatively). Most important for me is keeping at least some ranking/visibility, while I personally work on building quality links and helpful content. thanks!

                  How do Infographics provide links? (example inside)

                  Hi, I don't get it...
                  I've encountered the following infographic that seemed to do well: http://www.brilliance.com/4cs-of-diamonds-infograph As you can see, the page has thousands of social shares from Tweets to Facebook and obviously Pinterest. However, when I placed this page on Open Site Explorer (click to view) I see only 9 external links and page authority of 28/100. And this seems to me like a successful infographic. Any explanations? Thanks

                  Percentage of good links vs. bad

                  Hi Does anyone know the best way of determining good links from bad links using the SEO Moz tools? I bought some directory links to two or three pages on my site a few years back. The were all very obviously spammy because of the anchor text and I didn't have a high enough ratio of good links to counteract them. I read somewhere that if more than 10% of the links to a page have the same (or similar) anchor text, it's obvious that you're on the bad list.

                  How can I reduce the number of links on a page and keep the site easy to navigate?

                  The SEOmoz Site Crawl indicates that we have too many on page links on over 9,970 pages. This is an ecommerce site with a large number of categories. I have a couple of questions regarding this issue: How important is the "too many on page links" factor to SEO? What are some methods of reducing the number of links when there are a large number of categories? We have main categories with dropdown menus currently and have found that they are used to browse and shop the store.
