Hundreds of 404 errors are showing up for pages that never existed
-
For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style, but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal?
-
There have been a few people at Moz with similar problems with GSC. People always throw a few ideas around: maybe Google is creating URLs to try to find pages that it can't find through crawling links alone? Maybe another site was trying to hack your site by creating URLs they were hoping would trigger certain content on your site (a laughable idea now, but I remember my college professor showing us a site that put cost parameters in the URL during check out)?
However they got there, though, Eric and Chris gave you some good ways to make sure that you're not still in trouble (if you ever were).
Hope this helps!

I agree with Eric here so I won't repeat what he has said, simply offer additional suggestions.
Firstly, you can click on each entry from that Crawl Errors window in your screenshot and from the window that pops up, check out the "Linked From" tab. It will show you all the pages this broken one has links from.
If you're having no joy finding them on the pages manually, you can try the Screaming Frog SEO Spider. Crawl the site and if the 404s show up here (if they don't they probably don't exist anymore and you can mark them as "fixed" in Search Console) then click them and check out the "Linked From" tab at the bottom. This tool shows you not only the pages it's linked from but also the anchor text so you can go to the linking pages and use ctrl+f to find the offening link(s).
Hope that helps!

The 404 errors and other crawl data is provided by a separate database in Google, so the timing of the links and the data you're seeing isn't exactly "in sync" so to speak. I would do a few things--look at the pages to see if there's something on your site that might be causing the errors.
Another option is to look at the link data to see if there are any links pointing to those pages. I would use another source, such as OSE or Majestic.com to see if there are links pointing to those pages that Google isn't reporting (which is often the case).

Customer Reviews on Product Page / Pagination / Crawl 3 review pages only
Hi experts, I present customer feedback, reviews basically, on my website for the products that are sold. And with this comes the ability to read reviews and obviously with pagination to display the available reviews. Now I want users to be able to flick through and read the reviews to help them satisfy whatever curiosity they have. My only thinking is that the page that contains the reviews, with each click of the pagination will present roughly the same content. The only thing that changes is the title tags which will contain the number in the H1 to display the page number. I'm thinking this could be duplication but i have yet to be notified by Google in my Search console... Should i block crawlers from crawling beyond page 3 of reviews? Thanks

Does a no-indexed parent page impact its child pages?
If I have a page* in WordPress that is set as private and is no-indexed with Yoast, will that negatively affect the visibility of other pages that are set as children of that first page? *The context is that I want to organize some of the pages on a business's WordPress site into silos/directories. For example, if the business was a home remodeling company, it'd be convenient to keep all the pages about bathrooms, kitchens, additions, basements, etc. bundled together under a "services" parent page (/services/kitchens/, /services/bathrooms/, etc.). The thing is that the child pages will all be directly accessible from the menus, so there doesn't need to be anything on the parent /services/ page itself. Another such parent page/directory/category might be used to keep different photo gallery pages together (/galleries/kitchen-photos/, /galleries/bathroom-photos/, etc.). So again, would it be safe for pages like /services/kitchens/ and /galleries/addition-photos/ if the /services/ and /galleries/ pages (but not /galleries/* or anything like that) are no-indexed? Thanks!

SERPs started showing the incorrect date next to my pages
Hi Moz friends, I've noticed since Tuesday, November 9, half of my post's meta dates have changed in regards to what appears next to the post in the search results. Although published this year, I'm getting some saying a random date in 2010! (The domain was born in 2013; which makes this even more odd). This is harming the CTR of my posts and traffic is decreasing. Some posts have gone from 200 hits a day to merely 30. As far as on our end of the website, we have not made any changes in regards to schema markup, rich snippets, etc. We have not edited any post dates. We have actually not added new content since about a week ago, and these incorrect dates have just started to appear on Tuesday. Only changes have been updating certain plugins in terms of maintenance. This is occurring on four of our websites now, so it is not just specific to one. All websites use Wordpress and Genesis theme. It looks like only half of the posts are showing weird dates we've never seen before (far off from the original published date as well as last updated date -- again, dates like 2010, 2011, and 2012 when none of our websites were even created until 2013). We cannot think of a correlation as to why certain posts are showing weird dates and others the correct. The only change we can think of that's related is back in June we changed our posts to show Last Updated date to give our readers an insight into when we changed it last (since it's evergreen content). Google started to use that date for the SERPs which was great, it actually increased traffic. I'm hoping it's a glitch and a recrawl soon may help sift it around. Anybody have experience with this? I've noticed Google fluctuates between showing our last updated date or not even showing a date at all sometimes at random. We're super confused here. Thank you in advance!

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

Why are these internal pages not showing any internal links?
If you look at Author profile pages like this one, http://experts.allbusiness.com/author/denise-oberry (THE top contributor on the site with over 82 posts under her belt), or any Author profile page, they show zero internal links or Page Authority. The same goes for most posts for each author on the site. Author pages should show internal links from every post the author has on the site. And specific posts should also have internal links from categories, etc. Yet they show zero. The only posts that show internal links and PA are ones that were either syndicated to the root domain's homepage, or syndicated to Fox Small Business. ZERO internal links. Does anyone know why this is? The root domain does not act this way with Author pages and posts. And I see nothing blocking links or indexing via the robots.txt file or page level nofollow tags. A real head scratcher for this SEO nerd, that I'm sure someone here will have a really simple answer to.

Home Page .index.htm and .com Duplicate Page Content/Title
I have been whittling away at the duplicate content on my clients' sites, thanks to SEOmoz's pro report, and have been getting push back from the account manager at register.com (the site was built here and the owner doesn't want to move it). He says these are the exact same page and he can't access one to redirect to the other. Any suggestions? The SEOmoz report says there is duplicate content on both these urls: Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/index.htm Durango Mountain Biking | Durango Mountain Resort - Cascade Village http://www.cascadevillagehotel.com/ Your help is greatly appreciated!

404 Errors After Site Migration
Hello - I'm working on a website selling fashion accessories. The site just went through a site migration from Yahoo! to Big Commerce. Now we have a high level of warnings and errors from the crawl. Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled. How can I fix or did I do something wrong with migration? I was running the website with minimal errors and now overwhelmed with errors all the error updates. If I can get some assistance on what could be wrong, I would greatly appreciate. Thanks.
