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 At the moment we are manually trying to remove the links by using "Remove outdated content" tool whilst also creating a list of spammy links that might backlink to those spam pages we are removing, that were created by the virus.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

[Very Urgent] More 100 "/search/adult-site-keywords" Crawl errors under Search Console
I just opened my G Search Console and was shocked to see more than 150 Not Found errors under Crawl errors. Mine is a Wordpress site (it's consistently updated too): Here's how they show up: Example 1: URL: www.example.com/search/adult-site-keyword/page2.html/feed/rss2 Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword/page2.html Example 2 (this surprised me the most when I looked at the linked from data): URL: www.example.com/search/adult-site-keyword-2.html/page/3/ Linked From: www.example.com/search/adult-site-keyword-2.html/page/2/ (this is showing as if it's from our own site) http://a-spammy-adult-site.com/search/adult-site-keyword-2.html Example 3: URL: www.example.com/search/adult-site-keyword-3.html Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword-3.html How do I address this issue?

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!

I have a lot of spammy links coming to my 404 page (the URLs have been removed now). Should i re-direct to Home?
I have a lot of spammy links pointing at my website according to MOZ. Thankfully all of them were for some URLs that we've long since removed so they're hitting my 404. Should i change the 404 with a 301 and Re-Direct that Juice to my home page or some other page or will that hurt my ranking?

Weird 404 URL Problem - domain name being placed at end of urls
Hey there. For some reason when doing crawl tests I'm finding pages with the domain name being tacked on the end and causing 404 errors.

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!

Recovering from robots.txt error
Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

Do 404 pages pass link juice? And best practices...
Last year Google said bad links to 404 pages wouldn't hurt your site. Could that still be the case in light of recent Google updates to try and combat spammy links and negative SEO? Can links to 404 pages benefit a website and pass link juice? I'd assume at the very least that any link juice will pass through links FROM the 404 page? Many websites have great 404 pages that get linked to: http://www.opensiteexplorer.org/links?site=http%3A%2F%2Fretardzone.com%2F404 - that was the first of four I checked from the "60 Really Cool...404 Pages" that actually returned the 404 HTTP Status! So apologies if you find the word 'retard' offensive. According to Open Site Explorer it has a decent Page Authority and number of backlinks - but it doesn't show in Google's SERPs. I'd never do it, but if you have a particularly well-linked to 404 page, is there an argument for giving it 200 OK Status? Finally, what are the best practices regarding 404s and address bar links? For example, if
Intermediate & Advanced SEO | | Alex-Harford
www.examplesite.com/3rwdfs returns a 404 error, should I make that redirect to
www.examplesite.com/404 or leave it as is? Redirecting to www.examplesite.com/404 might not be user-friendly as people won't be able to correct the URL in the address bar. But if I have a great 404 page that people link to, I don't want links going to loads of random pages do I? Is either way considered best practice? If I did a 301 redirect I guess it would send the wrong signal to the crawlers? Should I use a 302 redirect, or even a 304 Not Modified redirect?1 -
How to prevent 404's from a job board ?
I have a new client with a job listing board on their site. I am getting a bunch of 404 errors as they delete the filled jobs. Question: Should we leave the the jobs pages up for extra content and entry points to the site and put a notice like this job has been filled, please search our other job listings ? Or should I no index - no follow these pages ? Or any other suggestions - it is an employment agency site. Overall what would be the best practice going forward - we are looking at probably 20 jobs / pages per month.
