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?

Migrating micro site into existing website
My company is planning to migrate an existing (ecommerce) micro site - which sits on its own domain - into their main ecommerce site. This means that the content will be moved from www.microdomain.co.uk to www.maindomain.com/category. Some products already exist on the main domain. The micro site is fairly small with just over 400 pages - I am planning to map each URL to the new URL (exact corresponding page) and create 301 redirects for each. Where any additional content does not exist yet on the existing main domain, we will create it and 301 redirect to it. The micro site currently ranks fairly well for some keywords - being such a specialised micro site, (some of) the keywords also form part of the domain name, however, they won't on the main page although they may form part of the URL (category). As an example (using a made up URL), our micro site www.bread-sticks.co.uk ranks on page 1 for the keyword bread sticks - we don't just sell bread sticks on www.bread-sticks.co.uk but also rolls and bread though, bread sticks is one category of very closely related categories. Say our main domain is www.supermarket.co.uk (selling a wide range of food / drink products. The micro site will be moving to www.supermarket.co.uk/baked-products/ - which is a category. Within that category, there are sub categories, i.e. bread sticks, rolls and bread which will sit under www.supermarket.co.uk/bread-sticks/ etc. What would be the best way for ensuring that our main domain would take over the rankings from our micro site, given that it will be sitting on our main domain as a category (one of many)? Can we expect www.supermarket.co.uk/baked-products/ or www.supermarket.co.uk/bread-sticks/ to replace www.bread-sticks.co.uk in the rankings simply by 301 redirecting? Thanks for your help!

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?

Blog Ranking NOT home page main website?!
Hi, Our Blog (http://blog.thailand-investigation.com) is ranking for some of our major keywords but not our home page (http://www.thailand-investigation.com)!? Our blog is WordPress and our main website is HTML. It seems like the search engines consider that they are 2 separate websites!? When I check the incoming links to our website, I get also the blog links!!!??? Is it normal? Do I have to build a relation of some kind or write some code saying that it is our Blog... I don't know! I'm not a SEO specialist or even a webmaster. I'm a small business owner and take care on my website. I created by myself but never learned! So, please help! Thanks

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?

What is the best website structure for SEO?
I've been on SEOmoz for about 1 month now and everyone says that depending on the type of business you should build up your website structure for SEO as 1st step. I have a new client click here ( www version doesn't work)... some bugs we are fixing it now. We are almost finished with the design & layout. 2nd question have been running though my head. 1. What would the best url category for the shop be /products/ - current url cat ex: /products/door-handles.html 2. What would you use for the main menu as section for getting the most out of SEO. Personally i am thinking of making 2-3 main categories on the left a section where i can add content to it (3-4 paragraphs... images maybe a video).So the main page focuses on the domain name more and the rest of the sections would focus on specific keywords, this why I avoid cannibalization. Main keyword target is "door handles" Any suggestions would be appreciated.
