Drop in DA across multiple sites
-
Hi
I monitor and track few Top sites that are Industry leaders. I got -1 to -3 in DA across this month. Has anyone else experienced this and the matter of fact is there has been rare or no change in the sites but the moz backlink data experienced a major drop "more then 100K backlinks were dropped for them in yesterday's report as compared to a 20 day old report".
Has anyone at Moz or anyone in the community experienced the same

I'm sorry about this!
Generally, we recommend using a wide variety of backlink tools to get the most illustrative picture of how your site's backlink profile looks. OSE and Ahrefs index differently and have different purposes. Ahrefs is good for quantity while OSE is great for finding higher quality links. You could always try Ahrefs to compare and potentially give your client the peace of mind that the links are still there.
Domain Authority is our own proprietary metric that is closely correlated to Google rankings, so our customers often use OSE to research influential sites to build links. (E.g. which links to try and target)

Thanks Eli for your quick response. This particular case is extreme and sudden - I'm trying to figure out the next step for my client. Everything else is going well with our SEO results - it's just DA and Moz not recognizing their backlinks in Feb - which dropped by 5K with the current index.
-
I also saw a drop in many of my client's DA with the most recent indexing, but I would agree with Eli – I work with small businesses, and so few of their links are of high quality, meaning it's likely Moz's index will be leaving them out.

Hey Linda,
Unfortunately it's impossible for me to predict whether they will be in our next index as I'm sure there were multiple factors that came into play when we released our latest index.

Sorry I can't be of anymore help!

Same problem. I had a client DA drop from 40 in January to 29 in Feb. Holy cow!
Looks like Moz did not recognize backlinks with 301 redirects that were previously recognized. Any thoughts on why these redirects were not included in the latest index? And - will this be reversed with the next index?
(redirects, in this case, were due to a new domain that was in place in mid-2017 - backlinks from the old domain had been included until this month).

Hey!
Thanks for reaching out to us!
Experiencing a lower Domain Authority drop like this is really nothing to worry about and is due to the fact that on the 5th February we released our latest index. Over the last few months, our index size has been fluctuating in size, and we simply may not have index certain websites / pages which are linking to your site, hence the fact that your DA reduced slightly.
Since Moz focuses on quality of links over quantity, we are always focused on the most relevant links to display to our users. It's possible that Moz's index will leave out some of the lower-quality links. So, that might explain why you may see some discrepancies with what other tools may be showing.
As a result, some of these metrics, like Domain Authority, can experience some unexpected trends. In general, I'd recommend keeping in mind that all of these metrics are relative with respect to the other sites included in the index. So, the metrics will probably have some additional context when compared to sites similar to your own.
If you'd like some extra info on how to interpret and investigate metrics like DA, be sure to check out this blog post from Rand: https://moz.com/community/q/da-pa-fluctuations-how-to-interpret-apply-understand-these-ml-based-scores
Hope this helps to explain and we hope our next release will bring your scores back up! (Around end of March) Feel free to reach out if there's anything else I can help with!

Moz was unable to crawl your site on Jun 22, 2020\. We were unable to access your site due to a page timeout on your robots.txt, which prevented us from crawling the rest of your site.
Site: www.kpmg.us Getting robots.txt timeout fail since 02/29/20. We've checked our server logs and see no errors. Went through all the steps of the "Troubleshooter". Updated robots.txt to allow rogerbot full access: User-agent: rogerbot

Open Site Explorer Messge - Mysite.com redirects to www.mysite.com
Hello All, When I plug in my site's URL http://mysite.com ( Not my actual URL of-course) into the OpenSiteExplorer tool I get the following message: "You entered the URL http://Mysite.com which redirects to http://www.Mysite.com/.
Link Explorer | | jjimen03
Because it's likely to have more accurate metrics, we're showing data for the redirected URL instead.
Click here to analyze http://Mysite.com instead?" Not sure why I am getting this message. On my hosting server, I have defined my preferred domain to be the non-www. version. I have also used a Canonical Tag on Mysite.com/index.html file ( ). In addition, on Google Search Console ( Webmaster Tools ) , I have added both the www. and non-www. properties, where on both property settings, I have defined the non-www. version as my preferred one. Also, on my server, I have not implemented any 301 redirects at all. So my questions are: Why am I receiving this message when plugging in my non-www. URL version of my website into OpenSiteExplorer? Is my DA or PA possibly being split up between the two versions as a result? Should I be concerned? How can I fix this? Thanks in advance.0 -
Why do my spammy backlinks still appear on my Open Site Explorer page after removal?
I used the organic spam backlink removal tactic of emailing owners of sites of spam rank 7 or higher on my page. It has been weeks since many of the harmful links were removed, yet they remain listed on my Open site Explorer page. My fear is that somehow simply getting these links removed doesn't exempt me from the potential to be penalized by Google crawlers. Does it take longer than a few weeks for these links to disappear from the Open Site Explorer, or is there something else I need to be doing? Any and all advice appreciated. Ben

How can I use Open Site Explorer to Identify why my own URL's are appearing as inbound links
I'm a new member of Moz, and am trying to understand why I am seeing my sites URL's in my Inbound Link results in Open Site Explorer. There are quite a few, and they are all product category URL's that are generated by my stores database. This is not happening with .html URL's. Any thoughts?

Open Site Explorer Recently Discovered Links Question
Hey Mozzers, I have a question regarding the Open Site Explorer Recently Discovered Links. I know that I have receive follow link from a few sites that have more DA than my site. I am wondering why it is taking so long for OSE to discover these links? I double checked the sites to make sure that they don't have NOFOLLOW (sorry for the double negative), and the sites have linked to my site for over a month now. Any ideas? I'm not concerned about it because Search Engines have discovered those links. I am just curious why this is, or if it is normal. Cheers!

Open Site Explorer not reporting all 301 redirected links
Our site had over 2,000 root domains linking to it as reported in MOZ Open Site Explorer (and Google Webmaster Tools). We then changed the domain and made sure that 301 redirects were set up for all pages across the site. That was about 1 month ago. Open Site Explorer is now reporting less than 300 linking root domains. For the links that it is reporting the majority of these are being 301 redirected to the new URLs (some of them we changed the links directly). However the majority of the links that are being 301 redirected are not being reported. It is reporting most of the links coming from the old to the new domain. Google Webmaster Tools is reporting over 1,000 linking root domains to the new domain (it has a max of 1,000). We did notice that MOZ took some time to update the domain authority of the new domain. It was 1 for along time and it has now jumped up to 46 ( it was previously at 74). Maybe this is a time delay thing and eventually Open Site Explorer will report all of the 301 redirected links? It is a bit frustrating at the moment as we can't fully analyse the links to the site to try to focus on the high domain linking sites to get them to change the link directly. Also, If all links are being 301 redirected to the new domain should the authority not be close to where it was previously after one month? Our search traffic has dropped considerably since the launch of the new site and hasn't returned yet, so just wondering if the 301 redirected links pass on as much value as thre original direct links. Thanks, Damien

Removing the clutter of site-wide links
I have a multi-part question with regard to the moz link index and some presentation suggestions. Firstly I would be interested to know how the link index treats site-wide links with regard to metrics such as DA, and PA. We all know that it is highly likely that SE's are unlikely to pass full link value across from sitewide links, and therefore it would make sense for Moz values to account for this as well - if they do not already. One annoying thing that also relates to sitewides is that they tend to clutter the much of the information presentation in a few of the tools (you can't see wood for trees as it were). This is most prominent in the "Just Discovered" page - if you have a sitewides on a large site, you can often find that this screen is just totally filled with these links as they are found. It would be very useful to be able to filter these out, as they are of little interest - currently I can't see a way of filtering them out. A further value where they create to much noise is the 'Total Links' value. Where sitewides are included in this value, the value actually becomes pretty meaningless as you can find that the majority of that value is sitewides. It would therefore be useful if there was another value for 'Total Links - Excluding Sitewides' where maybe value of 1 was just added to the count for a site wide
