    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:

      https://github.com/vigetlabs/redirector

      I hope that helps.

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

          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.

            301 redirect hops from non-https and www

            It's best practice to minimize the amount of 301 redirect hops. Ideally only one redirect hop. It's also best practice to 301 redirect (or at least canonical) your non-https and/or your non-www (or www) to the canonical protocol/subdomain. The simplest (and possibly the most common) way to implement canonical protocol/subdomain redirects is through a load balancer or before your app processes the request. Both of which will just blanket 301 to the canonical domain/protocol regardless if the path exists or not In which case, you could have: Two hops. i.e. hop #1 http://example.com/foo to https://example.com/foo, hop #2 https://example.com/foo to https://example.com/bar 301 to a 404. Let's say https://example.com/dog never existed, but somebody for whatever reason linked to it (maybe a typo). If I request https://www.example.com/dog, the load balancer would 301 to a 404 page. Either scenario above should be fairly rare. However, you can't control how people link to you. Should I care about either above scenario? I could have my app attempt to check if the page exists before forwarding, but that code could be complicated.

            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?

            Should we 301 redirect old events pages on a website?

            We have a client that has an events category section that is filled to the brim with past events webpages.  Another issue is that these old events webpages all contain duplicate meta description tags, so we are concerned that Google might be penalizing our client's website for this issue.   Our client does not want to create specialized meta description tags for these old events pages. Would it be a good idea to 301 redirect these old events landing pages to the main events category page to pass off link equity & remove the duplicate meta description tag issue?   This seems drastic (we even noticed that searchmarketingexpo.com is keeping their old events pages).  However it seems like these old events webpages offer little value to our website visitors. Any feedback would be much appreciated.

            For URLs that require login, should our redirect be 301 or 302?

            We have a login required section of our website that is being crawled and reporting as potential issues in Webmaster Tools. I'm not sure what the best solution to this is - is it to make URLs requiring a login noindex/nocrawl? Right now, we have them 302 redirecting to the login page, since it's a temporary redirect, it seems like it isn't the right solution. Is a 301 better?

            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?

            Geoip redirection, 301 or 302?

            Hello all Let me first try to explain what our company does and what it is trying to achieve. Our company has an online store, sells products for 3 different countries, and two languages for each country. Currently we have one site, which is open to all countries, what we are trying to achieve is make 3 different stores for these 3 different countries, so we can have a better control over the prices in each country. We are going to use Geoip to redirect the user to the local store in his country. The suggested new structure is to add sub-folders as following: www.example.com/ca-en
            www.example.com/ca-fr
            www.example.com/us-en
            ... If a visitor is located outside these 3 countries, then she'll be redirected to the root directory www.example.com/en We can't offer to expand our SEO team to optimize new pages for the local market, it's not the priority for now, the main objective now is to be able to control the prices for different market. so to eliminate the duplicate issue, we'll use canonical tags. Now knowing our objective from the new URL structure, I have two questions: 1- which redirect should we use? 301, 302? 
            If we choose 301, then which version of the site will get the link juice? (i.e, /ca-en or /us-en?)
            if we choose 302, then will the link juice remain in the original links? is it healthy to use 302 for long term redirections? 2- Knowing that Google bots comes from US-IP, does that mean that the other versions of the site won't be crawled (i.e, www.example.com/ca-fr), this is especially important for us as we are using AdWords, and unindexed pages will effect our quality score badly. I'd like to know if you have other account structure in your mind that would be better than this proposed structure. Your help is highly highly appreciated.
            Thanks in advance.

            301 Redirect - What happens to backlinks

            Hello... One of my sites is losing rankings in G. I received the webmaster notification of unnatural links... My question is, should i do a 301 redirect of every page on my site to a new domain? If so, do the backlinks (which i believe are causing my rankings to drop) carry over? How about the good backlinks? Also, what would happen to the rankings i currently have on page 1? Thanks

            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!
