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. 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.

How to handle potentially thousands (50k+) of 301 redirects following a major site replacement
We are looking for the very best way of handling potentially thousands (50k+) of 301 redirects following
Intermediate & Advanced SEO | | GeezerG
a major site replacement and I mean total replacement. Things you should know
Existing domain has 17 years history with Google but rankings have suffered over the past year and yes we know why. (and the bitch is we paid a good sized SEO company for that ineffective and destructive work)
The URL structure of the new site is completely different and SEO friendly URL's rule. This means that there will be many thousands of historical URL's (mainly dynamic ones) that will attract 404 errors as they will not exist anymore. Most are product profile pages and the God Google has indexed them all. There are also many links to them out there.
The new site is fully SEO optimised and is passing all tests so far - however there is a way to go yet. So here are my thoughts on the possible ways of meeting our need,
1: Create 301 redirects for each an every page in the .htaccess file that would be one huge .htaccess file 50,000 lines plus - I am worried about effect on site speed.
2: Create 301 redirects for each and every unused folder, and wildcard the file names, this would be a single redirect for each file in each folder to a single redirect page
so the 404 issue is overcome but the user doesn't open the precise page they are after.
3: Write some code to create a hard copy 301 index.php file for each and every folder that is to be replaced.
4: Write code to create a hard copy 301 .php file for each and every page that is to be replaced.
5: We could just let the pages all die and list them with Google to advise of their death.
6: We could have the redirect managed by a database rather than .htaccess or single redirect files. Probably the most challenging thing will be to load the data in the first place, but I assume this could be done programatically - especially if the new URL can be inferred from the old. Many be I am missing another, simpler approach - please discuss0 -
Website Redesign, 301 Redirects, and Link Juice
I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

Language Detection redirect: 301 or 302?
We have a site offering a voip app in 4 languages. Users are currently 302 redirected from the root page to /language subpages, depending on their browser language. Discussions about the sense of this aside: Is it correct to use a 302 redirect here or should users be 301 redirected to their respective languages? I don't find any guideline on this whatsoever...

Moving Content To Another Website With No Redirect?
I've got a website that has lots of valuable content and tools but it's been hit too hard by both Panda and Penguin. I came to the conclusion that I'd be better off with a new website as this one is going to hell no matter how much time and money I put in it. Had I started a new website the first time it got hit by Penguin, I'd be profitable today. I'd like to move some of that content to this other domain but I don't want to do 301 redirects as I don't want to pass bad link juice. I know I'll lose all links and visitors to the original website but I don't care. My only concern is duplicate content. I was thinking of setting the pages to noindex on the original website and wait until they don't appear in Google's index. Then I'd move them over to the new domain to be indexed again. Do you see any problem with this? Should I rewrite everything instead? I hate spinning content...!

Can I make 301 redirects on a Windows server (without access to IIS)?
Hey everyone, I've been trying to figure out a way to set up some 301 redirects to handle the broken links left behind after a site restructuring, but I can only ever find information on 2 methods that I can't use (as far as I can tell). The first method is to do some stuff with an htaccess file, but that looks like it only works on Linux-based servers. The method described for Windows servers is generally to install this IIS rewrite/redirect module and run that, but I don't think our web hosting company allows users to log directly into the server, so I wouldn't be able to use the IIS thing. Is there any other way to get a 301 redirect set up? And is this uncommon for a web hosting company to do, or do you all just run your sites on Linux-based servers or your own Windows machines? Thanks!

Multiple 301 Redirects for the Same Page
Hi Mozzers, What happens if I have a trail of 301 redirects for the same page? For example,
Intermediate & Advanced SEO | | Travis-W
SiteA.com/10 --> SiteA.com/11 --> SiteA.com/13 --> SiteA.com/14 I know I lose a little bit of link juice by 301 redirecting.
The question is, would the link juice look like this for the example above? 100% --> 90% --> 81% -->72.9%
Or just 100% -----------------------------------------> 90% Does this link juice refer to juice from inbound links or links between internal pages on my site? Thanks!0 -
301 or 302 Redirects to Mobile Site
When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here? Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?
