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.

Sorry I can't go into any more detail, but hopefully these links can help you get a handle on it. Best of luck! -
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?

What Tools Should I Use To Investigate Damage to my website
I would like to know what tools I should use and how to investigate damage to my website in2town.co.uk I hired a person to do some work to my website but they damaged it. That person was on a freelance platform and was removed because of all the complaints made about them. They also put in backdoors on websites including mine and added content. I also had a second problem where my content was being stolen. My site always did well and had lots of keywords in the top five and ten, but now they are not even in the top 200. This happened in January and feb. When I write unique articles, they are not showing in Google and need to find what the problem is and how to fix it. Can anyone please help

Multilingual website
My website is https://www.india-visa-gov.in and we are doing multilingual. There are three options 1. TLD eg india-visa-gov.fr (French) india-visa-gov.de (German) 2. Subdomain eg: fr.india-visa-gov.in (French) de.india-visa-gov.in (German) 3. Folders https://www.india-visa-gov.in/fr/ (French) https://www.india-visa-gov.in/de/ (German) We have tried the 3rd option but need to know whether its better or not for the long term health from SEO. Does the MOZ DA carry better in Subdomain or TLD or Folders? What does MOZ recommend to maintain DA? Thanks

Any SEO benefits of adding a Glossary to our website?
Hi all, I manage a website for a software company. Many terms can be quite tricky so it would be nice to add a Glossary page. Other than that, I have 2 questions: 1. What would be the SEO benefits? 2. How would you suggest to implement this glossary so we can get as much SEO benefit as possible (for example how would we link, where would we place the glossary in the terms of the sitemap, etc.). Any advice appreciated! Katarina

I have a GoDaddy website and have multiple homepages
I have GoDaddy website builder and a new website http://ecuadorvisapros.com and I notices through your crawl test that there are 3 home pages http://ecuadorvisapros with a 302 temporary redirect, http://www.ecuadorvisapros.com/ with no redirect and http://www.ecuadorvisapros/home.html. GoDaddy says there is only one home page. Is this going to kill my chances of having a successful website and can this be fixed? Or can it. I actually went with the SEO version thinking it would be better, but it wants to auto change my settings that I worked so hard at with your sites help. Please keep it simple, I am a novice although I have had websites in the past I know more about the what's than the how's of websites. Thanks,

Has google panelized us ? If so, why ? How do I know if our website is panelized ?
We were ranked on first page among top 5 position a year ago for most of our pages. On one fine day, google decided to drop us from the results although google keeps indexing our pages. Google index our pages regularly but doesn't show them in its results. All google traffic we receive is for our own site name and its variations. I wanted to know - how do we know if google has panelized us. Why has google panelized us ? If they have panelized us, what can we do to get out of it ? Also I wanted to know if any tool will help me identify such thing. We have not done any link building. Our site page rank is 4 (it was 5 few months ago). All we did was on page optimization. Thanks for your help!

How to find a specific link on my website (currently causing redirects)
Hi everyone, I've used crawlers like Xenu to find broken links before, and I love these tools. What I can't figure out is how to find specific pieces of code within my site. For example, Webmaster Tools tells me there are still links to old pages somewhere on my website but I just can't find them. Do you know of a crawler that can search for a specific link within the html? Thanks in advance, Josh

Does 'framing' a website create duplicate content?
Something I have not come across before, but hope others here are able offer advice based on experience: A client has independently created a series of mini-sites, aimed at targeting specific locations. The tactic has worked very well and they have achieved a large amount of well targeted traffic as a result. Each mini-site is different but then in the nav, if you want to view prices or go to the booking page, that then links to what at first appears to be their main site. However, you then notice that the URL is actually situated on the mini-site. What they have done is 'framed' the main site so that it appears exactly the same even when navigating through this exact replica site. Checking the code, there is almost nothing there - in fact there is actually no content at all. Below the head, there is a piece of code: <frameset rows="*" framespacing=0 frameborder=0> <frame src="[http://www.example.com](view-source:http://www.yellowskips.com/)" frameborder=0 marginwidth=0 marginheight=0> <noframes>Your browser does not support frames. Click [here](http://www.example.com) to view.noframes> frameset> Given that main site content does not appear to show in the source code, do we have an issue with duplicate content? This issue is that these 'referrals' are showing in Analytics, despite the fact that the code does not appear in the source, which is slightly confusing for me. They have done this without consultation and I'm very concerned that this could potentially be creating duplicate content of their ENTIRE main site on dozens of mini-sites. I should also add that there are no links to the mini-sites from the main site, so if you guys advise that this is creating duplicate content, I would not be worried about creating a link-wheel if I advise them to link directly to the main site rather than the framed pages. Thanks!
