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.

Google Is Indexing my 301 Redirects to Other sites
Long story but now i have a few links from my site 301 redirecting to youtube videos or eCommerce stores. They carry a considerable amount of traffic that i benefit from so i can't take them down, and that traffic is people from other websites, so basically i have backlinks from places that i don't own, to my redirect urls (Ex. http://example.com/redirect) My problem is that google is indexing them and doesn't let them go, i have tried blocking that url from robots.txt but google is still indexing it uncrawled, i have also tried allowing google to crawl it and adding noindex from robots.txt, i have tried removing it from GWT but it pops back again after a few days. Any ideas? Thanks!

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?

Remove URLs that 301 Redirect from Google's Index
I'm working with a client who has 301 redirected thousands of URLs from their primary subdomain to a new subdomain (these are unimportant pages with regards to link equity). These URLs are still appearing in Google's results under the primary domain, rather than the new subdomain. This is problematic because it's creating an artificial index bloat issue. These URLs make up over 90% of the URLs indexed. My experience has been that URLs that have been 301 redirected are removed from the index over time and replaced by the new destination URL. But it has been several months, close to a year even, and they're still in the index. Any recommendations on how to speed up the process of removing the 301 redirected URLs from Google's index? Will Google, or any search engine for that matter, process a noindex meta tag if the URL's been redirected?

How to 301 redirect old wordpress category?
Hi All, In order to avoid duplication errors we've decided to redirect old categories (merge some categories).
Intermediate & Advanced SEO | | BeytzNet
In the past we have been very generous with the number of categories we assigned each post. One category needs to be redirected back to blog home (removed completely) while a couple others should be merged. Afterwords we will re-categorize some of the old posts. What is the proper way to do so?
We are not technical, Is there a plugin that can assist? Thanks0 -
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...!

301 - should I redirect entire domain or page for page?
Hi, We recently enabled a 301 on our domain from our old website to our new website. On the advice of fellow mozzer's we copied the old site exactly to the new domain, then did the 301 so that the sites are identical. Question is, should we be doing the 301 as a whole domain redirect, i.e. www.oldsite.com is now > www.newsite.com, or individually setting each page, i.e. www.oldsite.com/page1 is now www.newsite.com/page1 etc for each page in our site? Remembering that both old and new sites (for now) are identical copies. Also we set the 301 about 5 days ago and have verified its working but haven't seen a single change in rank either from the old site or new - is this because Google hasn't likely re-indexed yet? Thanks, Anthony

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 Redirects After Company Acquisition
We recently acquired a company, and now we are going to redirect all of the pages on their site to their respective pages on our site. Do we need to keep the original pages on their site active? For how long? Ideally, we would like to redirect everything and remove the old site entirely so we don't have to pay to keep hosting it. Is this possible? Thanks!
