Why my DA dropped Suddenly?
-
-
I need info on embedding youtube videos inside blog posts as well. As per a study i found after inclusion of youtube embeds inside posts, the DA drops allot. But when we remove the embeds then DA comes back to normal.
Can somebody explains what is it with this behavior of DA?

Hi there,
Sam from Moz's Help Team here!
The change you've noticed would be due to the fact that we updated the way in which we calculate DA as of March 5th. The new DA has been launched with the purpose of improving our ability to predict a site’s ranking ability with even better accuracy. This update aims to give us a more accurate depiction of your site’s influence over time.
This doesn't mean we’ve started from scratch with our calculations; in fact, all of the features that went into the old DA model are also present in the new DA model as we’ve added more complexity around them. This includes a better understanding and consideration for the quality of the site linking to the site you’re researching, and links to a page that redirect to another page.
Please note, when tracking your DA and the Link Building work you’re performing, DA should always be looked at in comparison to your target competitors, never as a standalone metric.

I hope this helps but please let us know if there's more we can help to clarify!

How to increase the DA of a site?
I have done work on my site for 6 months, and still, I cannot find any progress because the DA in the MOZ is not increasing, and of course, I'm not getting rankings. What should I do now? I have been producing unique and new content too. Check my Site: http://www.apksoldier.com/avg-cleaner-pro-apk/

Same domain, different DA? (OSE)
Bit of an odd one here, anyone seen this before: https://i.gyazo.com/aa083d07c58623e101fc84b8b569a0cc.png

Could be the PA greater than the DA?
Hello users MOZ:

I have a question about page and domain authority. It is OK that sometimes PA is greater than the DA? I think that's not right, but it happens in some domains, for example in the attached image. uB7HZhr.png1 -
DA/PA Fluctuations: How to Interpret, Apply, & Understand These ML-Based Scores
Howdy folks, Every time we do an index update here at Moz, we get a tremendous number of questions about Domain Authority (DA) and Page Authority (PA) scores fluctuating. Typically, each index (which release approximately monthly), many billions of sites will see their scores go up, while others will go down. If your score has gone up or down, there are many potential influencing factors: You've earned relatively more or less links over the course of the last 30-90 days.
Link Explorer | | randfish
Remember that, because Mozscape indices take 3-4 weeks to process, the data collected in an index is between ~21-90 days old. Even on the day of release, the newest link data you'll see was crawled ~21 days ago, and can go as far back as 90 days (the oldest crawlsets we include in processing). If you've done very recent link growth (or shrinkage) that won't be seen by our index until we've crawled and processed the next index. You've earned more links, but the highest authority sites have grown their link profile even more
Since Domain and Page Authority are on a 100-page scale, the very top of that represents the most link-rich sites and pages, and nearly every index, it's harder and harder to get these high scores and sites, on average, that aren't growing their link profiles substantively will see PA/DA drops. This is because of the scaling process - if Facebook.com (currently with a DA of 100) grows its link profile massively, that becomes the new DA 100, and it will be harder for other sites that aren't growing quality links as fast to get from 99 to 100 or even from 89 to 90. This is true across the scale of DA/PA, and makes it critical to measure a site's DA and a page's PA against the competition, not just trended against itself. You could earn loads of great links, and still see a DA drop due to these scaling types of features. Always compare against similar sites and pages to get the best sense of relative performance, since DA/PA are relative, not absolute scores. The links you've earned are from places that we haven't seen correlate well with higher Google rankings
PA/DA are created using a machine-learning algorithm whose training set is search results in Google. Over time, as Google gets pickier about which types of links it counts, and as Mozscape picks up on those changes, PA/DA scores will change to reflect it. Thus, lots of low quality links or links from domains that don't seem to influence Google's rankings are likely to not have a positive effect on PA/DA. On the flip side, you could do no link growth whatsoever and see rising PA/DA scores if the links from the sites/pages you already have appear to be growing in importance in influencing Google's rankings. We've done a better or worse job crawling sites/pages that have links to you (or don't)
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 I 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. Long term, we are building a new indexing system that can process in real time and scale much larger, but this is a massive undertaking and is still a long time away. In the meantime, as our crawl shape changes to imitate Google, we may miss links that point to a site or page, and/or overindex a section of the web that points to sites/pages, causing fluctuations in link metrics. If you'd like to insure that a URL will be crawled, you can visit that page with the Mozbar or search for it in OSE, and during the next index cycle (or, possibly 2 index cycles depending on where we are in the process), we'll crawl that page and include it. We've found this does not bias our index since these requests represent tiny fractions of a percent of the overall index (<0.1% in total). My strongest suggestion if you ever have the concern/question "Why did my PA/DA drop?!" is to always compare against a set of competing sites/pages. If most of your competitors fell as well, it's more likely related to relative scaling or crawl biasing issues, not to anything you've done. Remember that DA/PA are relative metrics, not absolute! That means you can be improving links and rankings and STILL see a falling DA score, but, due to how DA is scaled, the score in aggregate may be better predictive of Google's rankings. You can also pay attention to our coverage of Google metrics, which we report with each index, and to our correlations with rankings metrics. If these fall, it means Mozscape has gotten less Google-shaped and less representative of what influences rankings. If they rise, it means Mozscape has gotten better. Obviously, our goal is to consistently improve, but we can't be sure that every variation we attempt will have universally positive impacts until we measure them. Thanks for reading through, and if you have any questions, please leave them for us below. I'll do my best to follow up quickly.13 -
6 Months and still no PA/DA or links by Moz Explorer?
Hi, It's been 6 months and my site is still showing no PA/DA or backlinks according to moz opensite explorer. I know that it has backlinks as I created them myself, and I know its crawlable and the links is there as GWT tells me so. Also you can check for yourself on ahrefs.com. Is Moz indexed pages that much smaller then the other crawlers? The site in question is amanandvan247.com. Thanks.

DA hasn't Moved over
We moved our site over a couple of weeks ago from bi-mi.com to bimi.co - its a magento site. We followed instructions to wait 2 weeks and upload a coming soon page etc to help google realise it was not just a parked domain. We moved everything over and then set a hta record up to redirect the "bi-mi" base domain to "bimi" , we then logged teh site move within web master tools also and I set the bimi.co preferred url etc. However its been about a week and half now and the DA is still showing as 1 and bi-mi (the old site that is redirecting) is showing as 18 Is it just patience needed here or have any of you also come across this issue?
