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
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 discuss

Sorry to hear of your woes.
Depending on the structure of the URLS you could create some simple pattern matches rules within .htaccess? If you could a few dozen rules could handle many thousands of redirects. If there isn't any easily identifiable pattern to match then a DB will, indeed, be your best option.
One of the web devs I used to work with (who was considerably smarter than me) faced a similar issue (with a 'mere' 10k+ redirects) and used some Ruby on Rails middleware as a redirector: This may have been the solution he used:

I hope that helps.
I hope you're able to get this sorted without too much pain. Good Luck!

Thank for the very quick response - you have picked my favourite solution. It will be interesting to hear other views and comments.

Hi,
1. Usually won't work and with 50k extra rules in your htaccess file it will for sure slow down the site as for every request to your server it has to go through the htaccess file.
For now I would recommend going with 6. with the information that you've provided. By doing it like this you can do a very quick check on your database and also in the request have the user send to the right page.
Martijn.

All URLs in the site is 302 redirected to itself
Hi everyone, I have a problem with a website wherein all URLs (homepage, inner pages) are 302 redirected. This is based on Screaming Frog crawl. But the weird thing is that they are 302 redirected to themselves which doesn't make any sense. Example:

https://www.example.com.au/ is 302 redirected to https://www.example.com.au/ https://www.example.com.au/shop is 302 redirected to https://www.example.com.au/shop https://www.example.com.au/shop/dresses is 302 redirected to https://www.example.com.au/shop/dresses Have you encountered this issue? What did you do to fix it? Would be very glad to hear your responses. Cheers!0 -
How to handle individual page redirects on Wix?
I switched from one domain to another because I wanted a domain that had our company name so it was more brand-y. However, the old domain had better DA/PA. Originally I set up a global 301 from the old to the new, but now I'm finding that I actually need to set up individual 301's from each URL of the old site, or at least from each page. However, I am using Wix so it looks like I can't always do URL-URL 301's, although I can redirect any URL to a page on the new website. The problem is that, in some cases, the content on the new site is different (or, for example, I can only link a particular blog post on the old site back to the new site's blog's main page). How closely do URLS/pages need to resemble each other for link juice to be transferred? Also, should I try to set up all these redirects manually or bite the bullet and go back to using the old domain? The problem is that I did a lot of beginner SEO junk for the new domain, like submitting to a few higher-quality directories, and getting our website on various industry resource sites, etc. I'd need to re-do this entirely if I go back to the old page. What do you think?

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?

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 🙂

Is it ok to use both 301 redirect and rel="canonical' at the same time?
Hi everyone, I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions. To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated. Would it be a problem to have both methods set up? Is it a problem to have a on a page that is redirecting to another one? Is it advisable to have a rel="canonical" tag on every single page? Thanks for reading!

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
