Why did my website DA fell down?
-
Hello,
Could you please let me know why might my website's DA have fallen down in merely a week? What might be a reason? I also noticed traffic from google dropped down at the very same week. Will be very thankful for any advise!

Sometimes Building backlinks from websites have high spam score might be the reason.

Hi there! Kristina from Moz's Help Team here.
Sorry to hear about your DA dropping. The reasoning behind this can be hard to pinpoint without the help of an SEO consultant or the specific web designer for your website. Domain and Page Authority scores are both calculated using Moz's Ranking Models. In essence, we take a lot of rankings data from the search engines (by running queries) and then try to build a predictive scoring system using our own on-page analyses and Mozscape link data to construct an algorithm that will effectively reproduce the search engines' results. Our current accuracy hovers in the 70% range, but over time, we expect to improve.
Once we have a ranking model (which we internally call "uber"), we can create scores that best approximate the combinations of all our page-specific link metrics or domain-specific link metrics (removing the keyword-specific features like anchor text, on-page keyword usage, etc). These scores represent the model's query-independent or non-keyword-based ranking inputs.
In simple terms, Domain Authority is our best prediction about how content would perform in search engine rankings on one site vs. another. Page Authority answers the same question for an individual page. Both are amalgamations of all the link metrics (number of links, linking root domains, mozRank, mozTrust, etc.) we have into a single, predictive score.
It's important to note that both Domain Authority and Page Authority are on a 100-point, logarithmic scale. Thus, it's much more difficult to grow your score from 70 to 80 than it would be to grow from 20 to 30.
It is also important to note that if the higher authority sites that your site is seeded from drop in score, it will ripple down to all of the other links branched off from the very top. A good place to start is to compare the DA from the linking root domains from the previous index. Also take a look at your competitors scores to see how much they have dropped as well. As our indexes grow in size, there are more links that are included in our calculations.
We recommend keeping track of how many linking root domains you have from index to index, as this will be a quick way to confirm possible reasons for an increase/decrease in the score.

5 to 1. Yeah then you probably were in the previous batch of data and are not included this time I guess. But do you also see a decrease in organic search traffic as for now you've only based it on this metric for now.
-
It was 5, and now it is 1. I am wondering what might have affected it at all? I have a service request form on my website, people used to fill it in, and now I don't get any inquiries at all. Yet I've been doing SEO for three months: I've build backlinks, my social accounts are active, I've optimized titles, meta descriptions, IMG Alts, and website content. Could you please tell me what might have gone wrong?

Hi,
The Domain Authority metric is only updated every couple of months. So that's why it could be that overtime it can drop a bit more then usual. What are you seeing of a kind of drop?

How valuable is a link with a DA 82 but a PA of 1?
Our county's website has a news' blog, and they want to do an article about an award we won. We're definitely going to do it, and we're happy about the link. However, all the other news' articles they have only have a PA of 1. The DA is 82, and the link is completely white hat. It's a govt site in our locale, however, with such a terrible PA, I'm don't think the link is really all that great from an SEO stand point. Am I right or wrong (or is it some dreadful murky grey area like everything else in this industry (which I'm thankful to be a part of 🙂 )? Thanks so much for any insights! Ruben

Website credits for designers - good or bad
Hi My core service is web design and development. I often place a credit on my clients websites pointing them back to my web design or web development pages. Is this a wise practice with penguin and panda updates? Would this also pull my ranking down?

Google is Showing Website as "Untitled"
My freelance designer made some changes to my website and all of a sudden my homepage was showing the title I have in Dmoz. We thought maybe the NOODP tag was not correct, so we edited that a little and now the site is showing as "Untitled". The website is http://www.chemistrystore.com/. Of course he didn't save an old copy that we can revert to. That is a practice that will end. I have no idea why the title and description that we have set for the homepage is not showing in google when it previously was. Another weird thing that I noticed is that when I do ( site:chemistrystore.com ) in Google I get the https version of the site showing with the correct title and description. When I do ( site:www.chemistrystore.com ) in Google I don't have the hompage showing up from what I can tell, but there are 4,000+ pages to the site. My guess is that if it is showing up, it is showing up as "Untitled". My question is.... How can we get Google to start displaying the proper title and description again?

Sitemap for dynamic website with over 10,000 pages
If I have a website with thousands of products, is it a good idea to create a sitemap for this website for the search engines where you show maybe 250 products on a page so it makes it easy for the search engine to find the part and also puts that part closer to the home page? Seems like google likes pages that are the closest to the home page (less clicks the better)

If a redirecting URL has more value than the website should I move it?
Client has two website addresses: Website A is a redirect to Website B. It has one indexed page. But this is the URL being used in collateral. It has the majority of back links, and citations everywhere list Website A as the URL. Website B is where the actual website lives. Google recognizes and indexes the 80+ pages. This website has very few backlinks going to it. This setup does not seem good for SEO. Moreover, the analytics data is completely messed up because Website B shows that the biggest referral source is... you guessed it Website A. I'm thinking going forward, I should: Move all the content from Website B to Website A. Setup Website B to permanently 301 Redirect to Website A. Is that the best course of action?
