Unable to fully see full spectrum of links built on some backlink checkers
-
We have built various links in directories and blogs to our website. We can clearly see that these links have been established on these websites. Some we have built well over 6 months ago.
However, upon using a range of tools such as Moz Open Explorer, Cognitive SEO Backlink Explorer and SEM Rush's Backlink Checker, we cannot see in any of these backlink checking tools the full spectrum of links we know we have built displayed. In instances of using these tools, we are only seeing a very small sample of links that we have built.
Our question here is then threefold:
- Why is it that a lot of these tools don't pick up the links we know we have built?
- Does google eventually see all the links we have built? Or does it suffer from the same problem as backlink checkers, unable to identify all built links?
- Is there a backlink checker that is throughly comprehensive, or close to, in its ability to identify all links? We have heard good things about Ahrefs and would love to hear people's thoughts here.

Thanks Jordan and Tawny! That is a good idea to check in GWT for link profiles of our sites that we want to check. We would love to find also though a link checking tool that is quite comprehensive. Thanks Tawny for your recommendation to check out Ahrefs. It is a tool we have trailed and do find quite effective!

Hi there! Tawny from Moz's Help team here. Thanks for writing in with a great question!
Since most backlink checkers don't have the massive resources that a search engine like Google has, it's unlikely that you'll be able to see all your backlinks using any one of them exclusively. For instance, Open Site Explorer is limited to showing you up to 10,000 backlinks at a time (any more than that and you'd need to use the Moz API), and from those, we can only show the top 25 links from each unique linking root domain.If you're not seeing all the backlinks you know you've earned using a backlink checker, but you do see it indexed in the search engines, it's probably because the search engine has used different means of finding those links. It's unlikely that search engines will have the same difficulty finding your backlinks as various backlink checkers will.
Moz is constantly working to improve the shape of our index - choosing which pages to crawl and which to ignore. Our goal is to build the most "Google-shaped" index we can, representative of what Google keeps in their main index and counts as valuable/important links that influence rankings. We make tweaks aimed at this goal each index cycle, but not always perfectly (you can see that in 2015, we crawled a ton more domains, but found that many of those were, in fact, low quality and not valuable, thus we stopped). Moz's crawlers can crawl the web extremely fast and efficiently, but our processing time prevents us from building as large an index as we'd like and as large as our competitors (you will see more links represented in both Ahrefs and Majestic, two competitors to Mozscape that we recommend). Moz calculates valuable metrics that these others do not (like PA/DA, MozRank, MozTrust, Spam Score, etc), but these metrics require hundreds of hours of processing and that time scales linearly with the size of the index, which means we have to stay smaller in order to calculate them.
I hope this helps! If you have follow-up questions, feel free to write in to help@moz.com!

This may be a silly question but have you checked in Google Webmaster tool's? I have noticed for some clients I work on Moz may not always show all the backlinks but it is still a good starting point to see if you have any questionable links pointing to your domain. Whereas Search Console or Webmaster tools gives a more complete breakdown of all my backlinks.
If you have Search Console set up download all your backlinks and compare it the other backlink checking tools you have.

In "Link Opportunities" is there a way to filter by external follow links that pass equity?
In Open Site Explorer, the "Link Opportunities" feature does not seem to have a way to filter for external follow links that pass equity. This would be very useful. Is this a feature in the pipeline or is there already a way to do this?

Not existing domains linking to my website (spam)
Hello, When i run my platform www.taobao.nl through https://moz.com/researchtools/ose/ i see a lot of nasty adult domains that link to my platform. These give a very negative (spam)score to my platform. I already disavowed quite a few via Webmastertools, but they keep coming. When i check the names in the Whois, they don't even seem to exist! (anymore) What could cause this and how can i end it?? Thanks for your help! Sander

Are Just Discovered Links Reports Working?
I can't find my 4 month old site in Open Site Explorer. But as the site has had all of its posts tweeted I checked the Just Discovered Links reports to see if it was mentioned there. My domain is http://www.genesisclub.training but the problem is that if I target "this root domain" - I get a bunch of links that are nothing to do with my site. For example the root domain report includes sites linking to www.tinmagpie.training www.goahead.training powerquery.training http://videoproduction.training http://www.eti.training http://linkedinsales.training and more, as sites linking to my root domain. In which universe? The Just Discovered algorithm looks like it isn't coping with the .training TLD. It is treating my domain as if it were genesisclub.training.com so now anything.training is in my root domain.

Linking C Blocks
Hello everyone! Just looking to get more information in regards to Linking C Blocks in layman's terms? We have dropped from 10 to 2 since the latest Moz Open Explorer update and are concerned about this score. Our highest competitor has doubled what they had on the last update. Anyone who can provide more information about this, we would greatly appreciate it. Thanks ahead of time!

Drastic Monthly Fluctuations in Page Link Metrics
We have experienced very drastic changes in our root domain numbers and as a result, have seen an odd impact on our DA. The data does not seem at all reliable at all. We went one month with over 50 recorded root domains and the next month that dropped over 75%. It doesn't make sense to be paying for a monthly pro account when the data is so clearly unreliable. What is going on? Looking for a good answer before closing our account!

Links from no-indexed pages in Open Site Explorer
I just looked up a site in Open Site Explorer. After putting in the site, I get a list of domains, links etc which is very useful. At the bottom is a note which I have pasted below. It mentions "24 links from no-indexed pages" and says we can't get any info on these. Is there a way to see what the 24 links are so I can investigate further?"Why does my number of inbounds links listed not match my total links count? The listed number may be slightly different because we only show 25 links per domain (so that you see a variety). Additionally you have 24 links from no-indexed pages. Unfortunately, we can't get info for those links."

Is there an efficient way to use Open Site Explorer to find unnatural or harmful links
We have a new client with 8 sites that we would like to 301 to a new site. However, before doing so we want to make sure that the backlinks are not unnatural or harmful in any way. Using open site explorer (other than just looking at exact anchor text vs brand anchor text ratio) is there a way to determine low quality inbound sites linking in? or any type of links google will find manipulative?

How Is a Page Crawled by Moz When Moz Says 'No Links'?
As above, really. I've crawled a new client's site to find the Moz crawler has identified a handful of 404 errors. The Moz crawler says these pages have '0 linking domains', and OSE has no data for these pages. So how are these pages being crawled by Moz and what should I advise my client?
