Why would my domain and page authority drop from 11 and 21, respectively, to 1 overnight?
-
Overnight the domain authority dropped from 11 to 1 and the page authority dropped from 21 to 1 with out any changes being made to the website.

Hi Ralph,
As Gaston mentioned, it's very, very possible—probably, even—this what you're seeing is a result of this month's somewhat smaller index (161 billion vs. 92 billion URLs). I'd really recommend this Rand post on PA/DA fluctuations, along with the ones Gaston has already mentioned.
A PA/DA of 1 almost always means we don't have information on the URL in question in the index. If the sites linking to you weren't indexed, then it's likely your site wasn't, either.
It's very likely that your site will be back in the index after the next update.

Hi Paul,
This other question, aswered by Rand Fishkin, might help to understand.Domain authority get down significantly. Internal MOZ Issue? Google Algoritm Update? - Moz q&A
Best luck!

We are seeing this on one of our domains as well (DA went from 16 to 8 overnight). While at the same time another domain with very similar link profile shot up from 18 to 34. Hard to make sense of it at this point.

Hi Ralph,
There are updates once or twice a month. Check them put here: Mozscape API Update
The reason for the drop, could be thousands. One of the main reasons is the backlinks, check whether your linkprofile has decreased or added any spammy links.
Best luck.
GR.

Why Dropping pages from SERPS?
Our website for my olansi company in London, China has hundreds of pages dedicated to every service we provide to China local areas. The total number of pages is approximately 100. Google caters pretty well for long-tail searches when it indexes all these pages, so we usually get a fair amount of traffic when this happens. However, Google occasionally drops most of our indexed pages from search engine results for a few days or weeks at a time - for example, Google is currently indexing 60 pages while last week it was back at 100. Can you tell me why this happens? When these pages don't display, we lose a lot of organic traffic. What are we doing wrong? Site url:https://www.olanside.com

Why is the Page Authority for posts in my blog so low
I have noticed that the Page Authority for my posts in my blog are all hovering around 1 and the rest of the pages on my website are around 20. The Domain Authority for my website is 16 and I think the page authority of my posts are negatively affecting my Domain Authority as I write more content. Any suggestions or recommendations as to why posts have such low Page Authority compared to similar pages. I have images, links, and great content in my posts, but they are considerably lower in Page Authority*

Redesigned and Migrated Website - Lost Almost All Organic Traffic - Mobile Pages Indexing over Normal Pages
We recently redesigned and migrated our site from www.jmacsupply.com to https://www.jmac.com It has been over 2 weeks since implementing 301 redirects, and we have lost over 90% of our organic traffic. Google seems to be indexing the mobile versions of our pages over our website pages. We hired a designer to redesign the site, and we are confident the code is doing something that is harmful for ranking our website. F or Example: If you google "KEEDEX-K-DS-FLX38" You should see our mobile page ranking: http://www.jmac.com/mobile/Product.aspx?ProductCode=KEEDEX-K-DS-FLX38 but the page that we want ranked (and we think should be, is https://www.jmac.com/Keedex_K_DS_FLX38_p/keedex-k-ds-flx38.htm) That second page isn't even indexed. (When you search for: "site:jmac.com Keedex K-DS-FLX38") We have implemented rel canonical, and rel alternate both ways. What are we doing wrong??? Thank you in advance for any help - it is much appreciated.

What should I do about not found pages?
I took over a site that had been hacked. A bunch of pages were created that said domain.com/cms/viagra. The pages are gone but they still show in webmaster tools as not being found, which is what I want. However, should I do anything besides leaving them as 404?

Website ranking went from page one to not in top 50 overnight. Help/suggestions?
One of our customer's websites initially ranked very well. For approximately 3 months it sat atop of Google for their optimized keywords. Suddenly, on November 17th, the ranking dropped and they were no longer in the top 50 for any keywords. We went through Google Webmaster tools and found no violations, so we emailed Google to see if we violated something and if they would reconsider. They responded "We reviewed your site and found no manual actions by the webspam team that might affect your site's ranking in Google." This is a site built on WordPress, so we turned off a majority of plugins in case one was somehow affecting the site. They have an incredible amount of business partners that link their website from their partner's website menus, so they have about 15,000 links all with anchor text "insurance." (every page on partner site is seen as a different link). Think this is affecting it? Maybe Google sees it as artificial? (P.S. This has been set up this way for a while before they came on with us). The site ranks on page one of Bing and Yahoo, but nowhere in top 50 for Google. Any suggestions? Appreciate the help!

Testimonial pages
Is it better to have one long testimonial page on your site, or break it down into several smaller pages with testimonials? First time I've posted on the forum. But I'm excited! Ron

Old domain vs. New keyword domain - Thoughts?
Okay. I'd like to get opinions as to what everyone thinks about domains lately. Here is any example: The current domain is general in nature, in fact, it's a persons name because they are a real estate agent. So the domain is something like JohnDoe.com. Current stats: Has approx. 130 linking domains pointing to it. Has over 300 incoming links from these linking domains. The link profile is clean and not spammy (not to say there are not a few that might be here and there) Was bough in 1994 The new domain would have very little value except it would be keyword rich such as PortlandHomesForSale.com (just an example). What are your thoughts. Thank you.

Discrepency between # of pages and # of pages indexed
Here is some background: The site in question has approximately 10,000 pages and Google Webmaster shows that 10,000 urls(pages were submitted) 2) Only 5,500 pages appear in the Google index 3) Webmaster shows that approximately 200 pages could not be crawled for various reasons 4) SEOMOZ shows about 1,000 pages that have long URL's or Page Titles (which we are correcting) 5) No other errors are being reported in either Webmaster or SEO MOZ 6) This is a new site launched six weeks ago. Within two weeks of launching, Google had indexed all 10,000 pages and showed 9,800 in the index but over the last few weeks, the number of pages in the index kept dropping until it reached 5,500 where it has been stable for two weeks. Any ideas of what the issue might be? Also, is there a way to download all of the pages that are being included in that index as this might help troubleshoot?
