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 At the moment we are manually trying to remove the links by using "Remove outdated content" tool whilst also creating a list of spammy links that might backlink to those spam pages we are removing, that were created by the virus.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

After hack and remediation, thousands of URL's still appearing as 'Valid' in google search console. How to remedy?
I'm working on a site that was hacked in March 2019 and in the process, nearly 900,000 spam links were generated and indexed. After remediation of the hack in April 2019, the spammy URLs began dropping out of the index until last week, when Search Console showed around 8,000 as "Indexed, not submitted in sitemap" but listed as "Valid" in the coverage report and many of them are still hack-related URLs that are listed as being indexed in March 2019, despite the fact that clicking on them leads to a 404. As of this Saturday, the number jumped up to 18,000, but I have no way of finding out using the search console reports why the jump happened or what are the new URLs that were added, the only sort mechanism is last crawled and they don't show up there. How long can I expect it to take for these remaining urls to also be removed from the index? Is there any way to expedite the process? I've submitted a 'new' sitemap several times, which (so far) has not helped. Is there any way to see inside the new GSC view why/how the number of valid URLs in the indexed doubled over one weekend?

URL Injection Hack - What to do with spammy URLs that keep appearing in Google's index?
A website was hacked (URL injection) but the malicious code has been cleaned up and removed from all pages. However, whenever we run a site:domain.com in Google, we keep finding more spammy URLs from the hack. They all lead to a 404 error page since the hack was cleaned up in the code. We have been using the Google WMT Remove URLs tool to have these spammy URLs removed from Google's index but new URLs keep appearing every day. We looked at the cache dates on these URLs and they are vary in dates but none are recent and most are from a month ago when the initial hack occurred. My question is...should we continue to check the index every day and keep submitting these URLs to be removed manually? Or since they all lead to a 404 page will Google eventually remove these spammy URLs from the index automatically? Thanks in advance Moz community for your feedback.

When should you 410 pages instead of 404
Hi All, We have approx 6,000 - 404 pages. These are for categories etc we don't do anymore and there is not near replacement etc so basically no reason or benefit to have them at all. I can see in GWT , these are still being crawled/found and therefore taking up crawler bandwidth. Our SEO agency said we should 410 these pages?.. I am wondering what the difference is and how google treats them differently ?. Do anyone know When should you 410 pages instead of 404 ? thanks Pete

Is a 404, then a meta refresh 301 to the home page OK for SEO?
Hi Mozzers I have a client that had a lot of soft 404s that we wanted to tidy up. Basically everything was going to the homepage. I recommended they implement proper 404s with a custom 404 page, and 301 any that really should be redirected to another page. What they have actually done is implemented a 404 (without the custom 404 page) and then after a short delay 301 redirected to the homepage. I understand why they want to do this as they don't want to lose the traffic, but is this a problem with SEO and the index? Or will Google treat as a hard 404 anyway? Many thanks

What are partial urls and why this is causing a sitemap error?
Hi mozzers, I have a client that recorded 7 errors when generating Xml sitemap. One of the errors appear to be coming from partial urls and apparently I would need to exclude them from sitemap. What are they exactly and why would they cause an error in the sitemap. Thanks!

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.

How important are sitemap errors?
If there aren't any crawling / indexing issues with your site, how important do thing sitemap errors are? Do you work to always fix all errors? I know here: http://www.seomoz.org/blog/bings-duane-forrester-on-webmaster-tools-metrics-and-sitemap-quality-thresholds Duane Forrester mentions that sites with many 302's 301's will be punished--does any one know Googe's take on this?
