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?

1000 Pages on old website. What to do with the 301 redirects for this domain?
Hi Moz Community, I have a 301 redirect question... I just acquired an old domain: Totally in my niche Domain is 14 years old Website exists of 1000 pages Great amount of backlinks Website is offline since about 2 weeks Will place a new website online asap with new url structure For the 50 best scoring pages I wrote a new, but fully comparable/related article. I will put a 301 redirect from those old to the new pages. My question: What to do with the 950 other url's? Should I put a 301 redirect to the homepage? Should I forward those pages to the 404 page? Should I divide the 950 url's with a 301 redirect to the 50 new ones? Another solution maybe? Any idea what would be the best solution so we can save as much Google juice as possible? Thanks in advance!

Do web design footer links of websites you build have value?
Hi everyone. I am trying to build up DA for my site and create linking opportunities with my clients sites but I am not seeing any link value. I just did a redesign with another firm and we built out www.denbow.com . We have links to our sites in the footer but for some reason it's not being indexed. Can someone help me understand if it is good to put built by a href link in the footer? I've built almost 12 sites in my first 1.5 years of being in business for myself and I thought the links would pass some sort of value. Thanks in advance for the help and education. Regards, Noob Gary

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

How to create a tree-like structure map of a website?
Hi all, The online marketing manager requested to make a tree-like map of the website. He means that he would like to see a graphical representation of the website and his contents. This way we will be able to see if there are internal link issues. The problem is that there are thousands of pages and many subdomains, manual labour would make this a very tedious task. If you would get this question, how would you try to solve this? Any software recommendation?

Why is my website banned?
IMy website is Costume Machine at www.costumemachine.com . My site has been banned for 1 year now. I have requested that google reconsider my site 3 times without luck. The site is dynamic and basically pulls in feeds from affiliate sites. We have added over 1,500 pages of original content. The site has been running great since 2008 without any penalties. I don't think I got hit with any linking penalty. I cleaned up all questionable links last November when the penalty hit. Am I being hit with a "thin" site penalty? If that is the issue what is the best way to fix the problem?

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!

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!
