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?

Concerned about Dup content between old and new website
I have an 8 year old plastic surgery website with my name in the url. I have just released a new website with a generic local plastic surgery url without my name. However my google authorship photo is appearing in listings from both sites with different URLs. So far Google is listing pages from both sites on the same google page result for similar search terms. However I am concerned that eventually I may be punished for dup content since I am the same author for both pages?

Website is not indexed in Google
Hi Guys, I have a problem with a website from a customer. His website is not indexed in Google (except for the homepage). I could not find anything that can possibly be the cause. I already checked the robots.txt, sitemap, and plugins on the website. In the HTML code i also couldn't find anything which makes indexing harder than usual. This is the website i am talking about: http://www.xxxx.nl/ (Dutch) The only thing that i am guessing now is the Google sandbox, but even that is quite unlikely. I hope you guys discover something i could not find! Thanks in advance 🙂

Duplicate Content within Website - problem?
Hello everyone, I am currently working on a big site which sells thousands of widgets. However each widget has ten sub widgets (1,2,3... say) My strategy with this site is to target the long tail search so I'm creating static pages for each possibly variation. So I'll have a main product page on widgets in general, and also a page on widget1, page on widget2 etc etc. I'm anticipating that because there's so much competition for searches relating to widgets in general, I'll get most of my traffic from people being more specific and searching for widget1 or widget 7 etc. Now here's the problem - I am getting a lot of content written for this website - a few hundred words for each widget. However I can't go to the extreme of writing unique content for each sub widget - that would mean 10's of 1,000's of articles. So... what do I do with the content. Put it on the main widget page was the plan but what do I do about the sub pages. I could put it there and it would make perfect sense to a reader and be relevant to people specifically looking for widget1, say, but could there be a issue with it being viewed as duplicate content. One idea was to just put a snippet (first 100 words) on each sub page with a link back to the main widget page where the full copy would be. Not sure whether I've made myself clear at all but hopefully I have - or I can clarify. Thanks so much in advance David

URL Duplicate Content Issues (Website Transition)
Hey guys, I just transitioned my website and I have a question. I have built up all the link juice around my old url styles. To give you some clarity: My old CMS rendered links like this: www.example.com/sweatbands My new CMS renders links like this: www.example.com/sweatbands/ My new CMS's auto-sitemap also generates them with the slash on the end. Also throughout the website the CMS links to them with the slash at the end and i link to them without the slash (because it's what i am used to). I have the canonical without the slash. Should I just 301 to the version with the slash before google crawls again? I'm worried that i'll lose all the trust and ranking i built up to the one without the slash. I rank very high for certain keywords and some pages house a large portion of our traffic. What a mess! Help! 🙂
