Hacked website - Dealing with 301 redirects and a large .htaccess file
-
One of my client's websites was recently hacked and I've been dealing with the after effects of it. The website is now clean of malware and I already appealed to Google about the malware issue. The current issue I have is dealing with the 20, 000+ crawl errors which are garbage links that were created from the hacking.
How does one go about dealing with all the 301 redirects I need to create for all the 404 crawl errors? I'm already noticing an increased load time on the website due to having a rather large .htaccess file with a couple thousand 301 redirects done already which I fear will result in my client's website performance and SEO performance taking a hit as well.

This is the correct answer.
To expand on this slightly, just make sure none of the 404s are internal (ie there are no links on your site pointing to one of these dodgy pages as a result of the hack) and you're all good.
Remove the entries from your htaccess file to avoid having to parse them constantly and let any external links to dodgy pages 404. This sort of circumstance is exactly what 404s are made for!
The only site at risk of a ranking drop from these 404s is the one pointing to those dodgy pages - who cares about your hackers' rankings?

So robots part could be at the end but in my case it worked fine too.

Just a correction here. Â I agree with all the items above, with one very, very, very, very, very important change.
DO NOT set the corrected urls to disallow in your robots.txt
If you do not allow Google to crawl the pages, Google will not see that the links were removed, that the page is now 4xx, etc. If you were to disallow all those pages, all the clean up work that you have done will not be seen by Google and would be for naught.
If you later want to disallow those pages, that would be fine, but you need to let Google see your clean up work first.

Hi
I just finished similar job.
What you should do:
- collect all bad "pages" and links pointing to them
- find a pattern like some kind of directory
- set them (directories I believe?) 410, not 404
- set robots to disallow those directories
- push all pages and links to reindex
- remove from Google index
- done (need to wait some time)
Important thing is to get rid of all bad links pointing to those pages. If you do that, then there'll be no issues. However this could be ongoing negseo. If you need help with that, pm me.

If they are garbage links, why are you redirecting them? Let them 404. Having not found pages does not lead to penalties, in and of itself.

Someone redirected his website to ours
Hi all, I have strange issue as someone redirected website http://bukmachers.pl to ours https://legalnibukmacherzy.pl We don't know exactly what to do with it. I checked backlinks and the website had some links which now redirect to us. I also checked this website on wayback machine and back in 2017 this website had some low quality content but in 2018 they made similar redirection to current one but to different website (our competitor). Can such redirection be harmful for us? Should we do something with this or leave it, as google stop encouraging to disavow low quality links.

301 Redirects to relative URLs not absolute a problem?
Hi we recently did a migration and a lot of content changed locations see: https://d.pr/i/RvqI81 Basically, the 301 goes to the correct location but its a relative URL (as you can see from the screenshot) rather than absolute URL. Do you think this is a high priority issue from an SEO standpoint, should we get the developer to change the redirects to absolute? Cheers.

Will 301 Redirects Slow Page Speed?
We have a lot of subdomains that we are switching to subfolders and need to 301 redirect all the pages from those subdomains to the new URL. We have over 1000 that need to be implemented. So, will 301 redirects slow the page speed regardless of which URL the user comes through? Or, as the old urls are dropped from Google's index and bypassed as the new URLs take over in the SERPs, will those redirects then have no effect on page speed? Trying to find a clear answer to this and have yet to find a good answer

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 -
Php 301 redirect
Hi I am migrating an old wordpress site to a custom PHP site and the URL profiles will be different, so want to retain all link profiles and more importantly if a user visits the old urls via search then they are seamlessly transferred to the new equivalent page For example www.domain.com/about-us is going to need to redirect to www.domain.com/aboutus.php www.domain.com/furniture is going to need to redirect to www.domain.com/furniture-collections.php etc What is the best way of achieving this apart from .htaccess as not 100% confident of doing this.  Could it be done via PHP or using meta tags?

How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it. How can it possible & How Google can crawl removed pages? You can see following image to know more about it. First & Second

Any way to find which domains are 301 redirected to competitors' websites?
By looking at the work from an SEO collegue it became clear that his weak linkbuilding graph probably is not the cause for his good rankings for a pretty competitive keyword. (also no social mentions where found) I was wondering what it could be, site structure and other on page optimization factors seems to be ok and I don't think there will be exceptionally good or bad user behavior... Finally I looked at the competitors and found that they have more links, better content en better design, so I got a little stuck. The only reason I can think of is that he is doing 301 redirects (or is rel=canonical tags). Is there a way to trace these redirects back to the source in order to include this important variable in your competitor research? thnx

301 Redirect With A Message And Delay
Hello, I'd like to sell a site I own. I'd like the site to be redirected to the buyers site with a 301 redirect. But I'd like the viewer to be informed that the site was purchased by this company and they will be redirect in 5 seconds.I'd like for the redirect to be a complete 301 and pass as much linklove as possible. Are you familiar with how to do this? Thanks, Tyler
