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?

My website is constantly decreasing
For few weeks ago my website is constantly decreasing in search position. I lost keywords and is gooooing down.
Technical SEO | | Dan_Tala
Although it is well rated on several on page and off page seo verification software that I have tried.
I checked Google search console and Analytics and found no major problems. However… from one day to another it keeps going down.
I also checked what the main competitors are doing and they are not doing well, at all.
The main competitor actually has a creepy website. Totally devoid of onpage or offpage SEO but with an enormous number of backlinks. And of a very bad quality, which should disqualify it, still…
Few weeks ago I changed something.
In the pages I had H1, 4xH2, no H3 and an H4 without content.
An unnatural H tag structure.
Now I have H1, H2, H3, 3xH4, with the coherent information.
Theoretically, Google should have been “happy” or I’m missing something. I use a SAAS platform.
I just found out that they made changes to the keywords (tags).
I am selling toner cartridges for printers.
So…
The tags are printer models and generate a url in which they have the products.
Ex. https://www.sertit.ro/cartus-imprimanta-cilindru-color-hp-laserjet-pro-m-177fw goes to the products for that printer model.
The question is… should I make tag canonical?
Is it possible for products to loose so much in Google search?0 -

What can I do to stop ranking for a keyword that has nothing to do with the companies website?
A website that we maintain keeps ranking for the keyword 'homeless shelter'. The company is UTILIS USA and they produce heavy duty shelters for military personnel. They have nothing to do with homeless shelters but continue to receive traffic concerning the phrase.

Fixing a website redirect situation that resulted in drop in traffic
Hi, I'm trying to help someone fix the following situation: they had a website, www.domain.com, that was generating a steady amount of traffic for three years. They then redesigned the website a couple of months ago, and the website developer redirected the site to domain.com but did not set up analytics on domain.com. We noticed that there was a drop in traffic to www.domain.com but have no idea if domain.com is generating any traffic since analytics wasn't installed. To fix this situation, I was going to find out from the developer if there was a good reason to redirect the site. What would have prompted the developer to do this if www.domain.com had been used already for three years? Then, unless there was a good reason, I would change the redirect back to what it was before - domain.com redirecting to www.domain.com. Presumably this would allow us to regain the traffic to the site www.domain.com that was lost when the redirect was put in place. Does this sound like a reasonable course of action? Is there anything that I'm missing, or anything else that I should do in this situation? Thanks in advance! Carolina

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?

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?
