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?

Redirecting an Entire Website?
Is it best to redirect an old website to a new website page by page to like pages or just the entire site all at once to the home page of the new site? I do have about 10 good pages on the site that are worth directing to corresponding pages on the new site. Just trying to figure out what is going to preserve the most link juice. Thanks for the help!

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?

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

pages and do nothing? We just received this in Google Webmasters tools: Google detected a significant increase in the number of URLs that return a 404 (Page Not Found) error. We have not updated the sitemap yet...Would this be enough to do or should we do more? You can view our website here: http://tinyurl.com/6la8 We removed the entire "Spring Planted Category"0 -
Sitemap for dynamic website with over 10,000 pages
If I have a website with thousands of products, is it a good idea to create a sitemap for this website for the search engines where you show maybe 250 products on a page so it makes it easy for the search engine to find the part and also puts that part closer to the home page? Seems like google likes pages that are the closest to the home page (less clicks the better)

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

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?
