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.

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

301 Redirecting from domain to subdomain
We're taking on a redesign of our corporate site on our main domain. We also have a number of well established, product based subdomains. There are a number of content pages that currently live on the corporate site that rank well, and bring in a great deal of traffic, though we are considering placing 301 redirects in place to point that traffic to the appropriate pages on the subdomains. If redirected correctly, can we expect the SEO value of the content pages currently living on the corporate site to transfer to the subdomains, or will we be negatively impacting our SEO by transferring this content from one domain to multiple subdomains?

Several 301 Redirects to Same Page
Hi, I have 3 Pages we won't use anymore in our website. Let's call them url A, url B and url C. To keep their SEO strength on our domain, I've though about redirecting all of them to url D. For what I understand, when 301 redirecting, about 85-90% of the link SEO juice is passed. Then, if I redirect 3 URLs to the same page... does url D receive all the link SEO juices for URLs added up? (approximately)

e.g. future url D juice = 100% current url D juice + 85% url A juice + 85% url B juice + 85% url C juice Is this the best practice, or is there a better way? Cheers,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?

Can I dissavow links on a 301'd website?
So we are performing link removal for a client on his old website (A), which is being 301 redirected to his new website (B). We have identified toxic links on site A and are removing, once complete we will undo the current 301, confirm a new GWT account for website A, and then submit the disavow report. We would then like to reapply the 301 redirect to site B while we are waiting for Google to process the disavow report, the logic being we can retain some current rankings on site B while waiting for the disavow to process on site A. Has anyone had experience with this method? I foresee some potential issues here but am interested to here from others on this. Thanks!

301 Redirection and apostrophes in URLs
Hi I am experiencing trouble getting any redirects with apostrophes in the URLs to 301 redirect in order to eliminate 404 errors. I have tried replacing the instance of the apostrophe in the source URL field to %27 and variations of this but to no avail. The site is a wordpress site (the old URLS are legacies from the old Business Catalyst site) and I am using the redirection plug in. I have gone into some detail with a helpful soul here http://wordpress.org/support/topic/how-to-deal-with-apostrophes-in-source-url but unfortunately to no result. If anyone has any idea how to solve this puzzle I would be grateful for the help.

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
