Welcome to the Q&A Forum

Dear SeoMAN, Thanks for your answer. I just tried at google, its shows normal, I just checked google search console and webmaster tools, there is nothing serious shows. Can it be possible to try to find out what was the main cause. Is I taken the right image, is I searched exactly what you are asking about? Many thanks. 7J2WLXd

I just got done reading the discussion between Brian Dean and Gianluca Fiorelli in reference to the "200 Google Ranking Factors" slightly throwing me for a loop on my thoughts for this. If we went by Brian, AKA Backlinko's methodology of site level factors theres kind of a mechanism behind the URL Extensions usage, and the actual domain name/subdomain. Assuming that Brian's factors are close to Googles actual algorithm and we take it to be accurate, the trump card is an exact match domain. second to that is when the site contains keywords in the beginning of name but not the entire phrase and then next is keywords anywhere in domain. Then Sub Domains, and lastly url extensions. for your 2nd url, I wouldn't use the url extension you selected because it's in the domain name. I kind of had a similar link structure on my first drop shipping store and I kept using "Burlesque" for every single thing, and I don't think it gave me an edge. One of my best structured sites was an adult affiliate domain and I basically took 1 thing that was pretty much just 1 single genre and just completely dissected it into hair color, eye color, nationality, wardrobe, celebrities on and on and on. Basically what I'm eluding to is that im not knowledgable in this particular vastu buildings, but you certainly are.  Perhaps the way to structure it would be based upon different sub types, maybe even the historians that developed and found their variances, like.. Silpa Prakasa? Because then you'd have more keywords and an exansion of relevance in your content increasing the odds of longtails. As far as clarity and simplifying the obstacle at hand which is to get in the top ranks of the key term I think perhaps something innovative and unique implemented into your content would add some new flavor and obtain the audiences reactions necessary to boost you back into the game. Videos Infographs Images with superiorly optimized dimensions and metrics that include captions I think those would be game breaking! Where it stands your domain's DA matches the difficulty of the key term. So I theorize adding some amazing to the content would be the game changer needed! You see "Stealing Backlinks my little baby blog couldn't possibly make board against neil patel and brian dean in the race. But image number 4 was number 1 for like a month. Google has some amazing dynamic to it's algorithm and if you produce high grade stuff, it knows! dDuM7jJ.png

Hi there, Thanks for writing in - Sam from Moz's Help Team here! That's such a good question, we made an entire resource page about it. (https://moz.com/learn/seo/domain-authority) There's also a video! Here's a preview: Domain Authority is a score (on a 100-point scale) developed by Moz that predicts how well a website will rank on search engines. Use Domain Authority when comparing one site to another or tracking the “strength” of your website over time. We calculate this metric by combining all of our other link metrics—linking root domains, number of total links, MozRank, MozTrust, etc.—into a single score. In terms of DA dropping, we do get a number of questions about this - overall, DA numbers dropping with an index update is a fairly common problem and can be attributed to a few things: 1.You've earned relatively more or less links over the course of the last 30-90 days. 2. You've earned more links, but the highest authority sites have grown their link profile even more. 3. The links you've earned are from places that we haven't seen correlate well with higher Google rankings. 4. We've done a better or worse job crawling sites/pages that have links to you (or don't). It's a bit difficult to isolate the exact cause of what happened without your own SEO consultant or developer being able to take a dive into this, but you can definitely read more specific information here: https://moz.com/community/q/da-pa-fluctuations-how-to-interpret-apply-understand-these-ml-based-scores if you'd like to understand more about the process:). A great place to start with improving DA could be to focus on link building! You can learn more about link building here and get a more detailed explanation of Domain Authority through this resource. In general, I'd recommend keeping in mind that all of these metrics are relative with respect to the other sites included in our index. The metrics will probably have some additional context when compared to sites similar to your own, including your competitors. Feel free to give those resources a once over to see if they help clarify some of your questions! I hope this helps!
