      I've read through the forum, but I'm confused as to what "Number of Linking Root Domains" means in the Linking Domains report. For example, if the root domain is Moz.com and the number is 135,000 does that mean there are 135,000 links from Moz pointing back to my site or does it mean there are 135,000 sites linking back to Moz?

      Any help is appreciated. Thank you!

            That sounds correct to me - if the number of Linking Root Domains associated with SearchEngineLand is 135,000, that's links pointing to SearchEngineLand's domain, not Moz's domain. 🙂

              Hello there!
              Just to help Tawny clarify this.

              In those reports, " Root Domain" means just the domain. In the case of Moz, it is moz.com. This also means that they are taking into account the whole site.
              So, for example, consider that you have 3 pages:

              1. site.com
              2. site.com/landing-page-A
              3. site.com/important-keyword

              On one hand, if every page has one separate link pointing, fron different sites. Let's say: example-1.com, my-blog.org and site-overseas.com
              In the report, when checking for site.com, you'll fine 3 root domain links.
              On the other hand, if every page ( just to keep it generalistic, but it could be applied for just onepage) gets a link from the same root domain, but from diffetent pages (let's say: site-A.net/page1, site-A.net/keyword-two and site-A/whatever) in the repport you'll see just **ONE **root domain link.

              Can you see the difference?

              Hope I've helped.
              GR.

                Thanks Tawny. So just to make sure I absolutely understand, here's another example:

                If the root domain I entered in Open Site Explorer is www.moz.com and one of the root domains that appears in the resulting Linking Domains report is SearchEngineLand and the number of Linking Root Domains associated with SearchEngineLand is 135,000, that means SearchEngineLand has 135,000 sites linking back to it -- not Moz right?

                  Hey there! Tawny from Moz's Help Team here!

                  The number of Linking Root Domains you see is links from other sites pointing back to your root domain (or the root domain you entered in the search bar in Open Site Explorer). So, in your example, that would be 135,000 sites linking back to moz.com somewhere on the site.

                  I hope that helps! If you have any more questions, feel free to drop us a line at help@moz.com and we'll answer them for ya! 🙂

                    da page authority

                    Hello everyone. My website (I am attaching the link to it, if you cannot attach the link remove it but please give me an answer) https://mejorhora.com/ 3 MONTHS ago I made different redirections from other websites that I have with high authority in order to increase both the Da and the DR since I sell links to that website and it suits me. Ahref showed me all the links after a few days, also in search console. However, in Moz it does not recognize more than 500 new domains that give me links. Because? It's been 3 months... What should I do?

                    link explorer backling issue

                    When looking at the backlinks for a client's competitor I found that they had a backlink on search.yahoo.com/reviews and our domain (harmonyhit.com) did not. I was using the Link Explorer tool. However, when I go to yahoo Search I see that the website of harmonyhit.com is indexed in Yahoo search and has links to the site. Also, it's sitemap has been recently crawled in Bing webmaster tools which Yahoo uses. Why does our client have the backlink accounted for and we do not?

                    If I migrate to a new domain, does my Domain Authority score get migrated also?

                    For business reasons, I migrated my domain with a DA score of 85 to a new domain.  After some time, the DA score on the new domain is only 45.  My migration plan and redirects went smooth and all redirected with best practices in mind.  I am still ranking well for almost all of the keywords where I've 301 redirected old URL to new. Any feedback welcome!

                    WP Events Calendar Creates URLs Too Long in Site Crawler

                    My travel/tourism site is on WP and using an Events plugin that ads a calendar of events to many pages. The MOZ crawler is indexing almost 46K links with a URL too long, but the site only has about 3.8K pages indexed in Google. I can tell MOZ is indexing the same pages over and over again but just adding a random calendar month and year.  Here are some examples. https://www.visitcurrituck.com/four-day-stay/?full=1&long_events=1&country[0]=US&ajaxCalendar=1&mo=10&yr=2003 https://www.visitcurrituck.com/four-day-stay/?full=1&long_events=1&country%5B0%5D=US&ajaxCalendar=1&mo=10&yr=2034 https://www.visitcurrituck.com/beach-houses-family-time/?full=1&long_events=1&country%5B0%5D=US&ajaxCalendar=1&mo=1&yr=1873 Any advice on how to prevent MOZ from indexing this way? I don't believe that Google is seeing this also, but maybe they are. I just know my site has over 63K issues and I'm sure at least 75% or more is because of the way they are picking up on the events calendar. Thanks!

                    How does spammy linked site have zero spam score?

                    I came across a law firm site with hundreds of horrible spam links to it. Of the 3330 links, all but 231 links have anchor text that has to do with "jordan 11s for sale". I'm trying to see how useful the moz spam score is, but clearly it's not reliable if this site has a score of zero. Many of the obviously spammy sites linking to it also have low to zero spam scores, although there are plenty in the 5-10 range. (see attached image). I also noticed that many sites were legit sites, but if you look at the source code, there's tons of hidden spam links in the code (e.g., www.chickasawgardens.net) Why would this site have a zero spam score? If you're curious, put it into open site explorer and have a look. It's a law firm based in Pennsylvania, most anchor text has to do with jordan sneakers and most links are foreign: penn-criminallawyers.com Is the spam score too lenient? Is the moz tool unable to find spam links coming from legitimate sites with hidden spam links? DrokMbP
