Not found errors (404) due to being hacked
-
Hi Moz Guru's
Our website was hacked a few months ago, since then we have taken various measures, last one being redesigning the website all together and removing it from a WordPress platform. So far all is going well, except that the 404 not found errors keeps coming up in Google Webmaster tools. The URLs are spam pages that were created by the virus. And these spam pages have been indexed by Google, and now we are struggling to get rid of them.
Is there any way we can deal with these 404 spam pages links? Is marking all of them as fixed in the webmaster tools - search console- crawl errors helpful in any way? Can this have a negative impact on the SEO ?
Looking forward to your answers.
Many thanks.

I have a new client and just discovered on Open Site Explorer hundreds of links to ghost pages. The anchor text is stuff like Criminal Background Checks Las Vegas or Find Missing Persons.
I am not the webmaster. What advice should I give him?

Green Stone,
Thank you for your reply. At the moment we are manually trying to remove the links by using "Remove outdated content" tool whilst also creating a list of spammy links that might backlink to those spam pages we are removing, that were created by the virus.
Thank you.

Monica,
Sounds like you guys have taken the necessary steps to clean up the website and prevent it from occurring again. 404 spam links are a pain, that can often take some time to be removed from google's index all-together.
- A way to speed up the process is by changing the 404 status of these pages, and having it return a "410" error instead. This tells google it is a permanent non-existent page, and thus it will fall out of the index more quickly than a regular 404.
- In the meantime, if the number of 404 errors aren't overwhelming, you could try the "remove urls" tool within search console for these pages, which will temporarily remove them from the index all together. (emphasis on temporary)
- Marking them as fixed wouldn't be helpful, as the errors still exist, and would return to your search console not long after. (it certainly wouldn't harm your SEO, it just wouldn't be very helpful in this specific instance).
Hope that helps.

Moved company 'Help Center' from Zendesk to Intercom, got lots of 404 errors. What now?
Howdy folks, excited to be part of the Moz community after lurking for years! I'm a few weeks into my new job (Digital Marketing at Rewind) and about 10 days ago the product team moved our Help Center from Zendesk to Intercom. Apparently the import went smoothly, but it's caused one problem I'm not really sure how to go about solving: https://help.rewind.io/hc/en-us/articles/*** is where all our articles used to sit https://help.rewind.io/*** is where all our articles now are So, for example, the following article has now moved as such: https://help.rewind.io/hc/en-us/articles/115001902152-Can-I-fast-forward-my-store-after-a-rewind- https://help.rewind.io/general-faqs-and-billing/frequently-asked-questions/can-i-fast-forward-my-store-after-a-rewind This has created a bunch of broken URLs in places like our Shopify/BigCommerce app listings, in our email drips, and in external resources etc. I've played whackamole cleaning many of these up, but these old URLs are still indexed by Google – we're up to 475 Crawl Errors in Search Console over the past week, all of which are 404s. I reached out to Intercom about this to see if they had something in place to help, but they just said my "best option is tracking down old links and setting up 301 redirects for those particular addressed". Browsing the Zendesk forms turned up some relevant-ish results, with the leading recommendation being to configure javascript redirects in the Zendesk document head (thread 1, thread 2, thread 3) of individual articles. I'm comfortable setting up 301 redirects on our website, but I'm in a bit over my head in trying to determine how I could do this with content that's hosted externally and sitting on a subdomain. I have access to our Zendesk admin, so I can go in and edit stuff there, but don't have experience with javascript redirects and have read that they might not be great for such a large scale redirection. Hopefully this is enough context for someone to provide guidance on how you think I should go about fixing things (or if there's even anything for me to do) but please let me know if there's more info I can provide. Thanks!

Site structure: Any issues with 404'd parent folders?
Is there any issue with a 404'd parent folder in a URL? There's no links to the parent folder and a parent folder page never existed. For example say I have the following pages w/ content: /famous-dogs/lassie/
Intermediate & Advanced SEO | | dsbud
/famous-dogs/snoopy/
/famous-dogs/scooby-doo/ But I never (and maybe never plan to) created a general **/famous-dogs/ **page. Sitemaps.xml does not link to it, nor does any page on my site. Is there any concerns with doing this? Am I missing out on any sort of value that might pass to a parent folder?0 -
This url is not allowed for a Sitemap at this location error using pro-sitemaps.com
Hey, guys, We are using the pro-sitemaps.com tool to automate our sitemaps on our properties, but some of them give this error "This url is not allowed for a Sitemap at this location" for all the urls. Strange thing is that not all of them are with the error and most have all the urls indexed already. Do you have any experience with the tool and what is your opinion? Thanks

Should I Keep adding 301s or use a noindex,follow/canonical or a 404 in this situation?
Hi Mozzers, I feel I am facing a double edge sword situation. I am in the process of migrating 4 domains into one. I am in the process of creating URL redirect mapping The pages I am having the most issues are the event pages that are past due but carry some value as they generally have one external followed link. www.example.com/event-2008 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2007 301 redirect to www.newdomain.com/event-2016 www.example.com/event-2006 301 redirect to www.newdomain.com/event-2016 Again these old events aren't necessarily important in terms of link equity but do carry some and at the same time keep adding multiple 301s pointing to the same page may not be a good ideas as it will increase the page speed load time which will affect the new site's performance. If i add a 404 I will lose the bit of equity in those. No index,follow may work since it won't index the old domain nor the page itself but still not 100% sure about it. I am not sure how a canonical would work since it would keep the old domain live. At this point I am not sure which direction I should follow? Thanks for your answers!

Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
We are building URLs dynamically with apache rewrite.
Intermediate & Advanced SEO | | lcourse
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0 -
What are Soft 404's and are they a problem
Hi, I have some old pages that were coming up in google WMT as a 404. These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page. However these are now listed in WMT as soft 404's. I'm not sure what this means and whether google is saying it doesn't like this? Any advice welcomed.

Generating 404 Errors but the Pages Exist
Hey I have recently come across an issue with several of a sites urls being seen as a 404 by bots such as Xenu, SEOMoz, Google Web Tools etc. The funny thing is, the pages exist and display fine. This happens on many of the pages which use the Modx CMS, but the index is fine. The wordpress blog in /blog/ all works fine. The only thing I can think of is that I have a conflict in the htaccess, but troubleshooting this is difficult, any tool I have found online seem useless. Have tried to rollback to previous versions but still does not work. Anyone had any experience of similar issues? Many thanks K.
