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.

301 Redirect in breadcrumb. How bad is it?
Hi all, How bad is it to have a link in the breadcrumb that 301 redirects? We had to create some hidden category pages in our ecommerce platform bigcommerce to create a display on our category pages in a certain format. Though whilst the category page was set to not visable in bigcommerce admin the URL still showed in the live site bread crumb. SO, we set a 301 redirect on it so it didnt produce a 404. However we have lost a lot of SEO ground the past few months. could this be why? is it bad to have a 301 redirect in the breadrcrumb.

Is there any benefit to changing 303 redirects to 301?
A year ago I moved my marketplace website from http to https. I implemented some design changes at the same time, and saw a huge drop in traffic that we have not recovered from. I've been searching for reasons for the organic traffic decline and have noticed that the redirects from http to https URLs are 303 redirects. There's little information available about 303 redirects but most articles say they don't pass link juice. Is it worth changing them to 301 redirects now? Are there risks in making such a change a year later, and is it likely to have any benefits for rankings?

1 duplicate I have recently transfered my old html site to wordpress.
To keep the urls the same I am using a plugin which appends .htm at the end of each page. My old site home page was index.htm. I have created index.htm in wordpress as well but now there is a conflict of duplicate content. I am using latest post as my home page which is index.php Question 1.
Should I also use redirect 301 im htaccess file to transfer index.htm page authority (19) to www.example.com If yes, do I use
Redirect 301 /index.htm http://www.example.com/index.php
or
Redirect 301 /index.htm http://www.example.com Question 2
Should I change my "Home" menu link to http://www.example.com instead of http://www.example.com/index.htm that would fix the duplicate content, as indx.htm does not exist anymore. Is there a better option? Thanks0 -
Changing URL structure of date-structured blog with 301 redirects
Howdy Moz, We've recently bought a new domain and we're looking to change over to it. We're also wanting to change our permalink structure. Right now, it's a WordPress site that uses the post date in the URL. As an example: http://blog.mydomain.com/2015/01/09/my-blog-post/ We'd like to use mod_rewrite to change this using regular expressions, to: http://newdomain.com/blog/my-blog-post/ Would this be an appropriate solution? RedirectMatch 301 /./././(.) /blog/$1

Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?
We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

Moving half my website to a new website: 301?
Good Morning! We currently have two websites which are driving all of our traffic. Our end goal is to combine the two and fold them into each other. Can I redirect the duplicate content from one domain to our main domain even though the URL's are different. Ill give an example below. (The domains are not the real domains). The CEO does not want to remove the other website entirely yet, but is willing to begin some sort of consolidation process. ABCaddiction.com is the main domain which covers everything from drug addiction to dual diagnosis treatment. ABCdualdiagnosis.com is our secondary website which covers everything as well. Can I redirect the entire drug addiction half of the website to ABCaddiction.com? With the eventual goal of moving everything together.

Splitting one Website into 2 Different New Websites with 301 redirects, help?
Here's the deal. My website stbands.com does fairly well. The only issue it is facing a long term branding crisis. It sells custom products and sporting goods. We decided that we want to make a sporting goods website for the retail stuff and then a custom site only focusing on the custom stuff. One website transformed and broken into 2 new ones, with two new brand names. The way we are thinking about doing this is doing a lot of 301 redirects, but what do we do with the homepage (stbands.com) and what is the best practice to make sure we don't lose traffic to the categories, etc.? Which new website do we 301 the homepage to? It's rough because for some keywords we rank 3 or 4 times on the first page. Scary times, but something must be done for the long term. Any advise is greatly appreciated. Thank you in advance. We are set for a busy next few months 🙂
