      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.

              302 > 302 > 301 Redirect Chain Issue & Advice

              Hi everyone, I recently relaunched our website and everything went well. However, while checking site health, I found a new redirect chain issue (302 > 302 > 301 > 200) when the user requests the HTTP and non-www version of our URL. Here's what's happening: • 302 #1 -- http://domain.com/example/ 302 redirects to http://domain.com/PnVKV/example/ (the 5 characters in the appended "subfolder" are dynamic and change each time)
              • 302 #2 -- http://domain.com/PnVKV/example/ 302 redirects BACK to http://domain.com/example/
              • 301 #1 -- http://domain.com/example/ 301 redirects to https://www.domain.com/example/ (as it should have done originally)
              • 200 -- https://www.domain.com/example/ resolves properly We're hosted on AWS, and one of my cloud architects investigated and reported GoDaddy was causing the two 302s. That's backed up online by posts like https://stackoverflow.com/questions/46307518/random-5-alpha-character-path-appended-to-requests and https://www.godaddy.com/community/Managing-Domains/My-domain-name-not-resolving-correctly-6-random-characters-are/td-p/60782. I reached out to GoDaddy today, expecting them to say it wasn't a problem on their end, but they actually confirmed this was a known bug (as of September 2017) but there is no timeline for a fix. I asked the first rep I spoke with on the phone to send a summary, and here's what he provided in his own words: From the information gathered on my end and I was able to get from our advanced tech support team, the redirect issue is in a bug report and many examples have been logged with the help of customers, but no log will be made in this case due to the destination URL being met. Most issues being logged are site not resolving properly or resolving errors. I realize the redirect can cause SEO issues with the additional redirects occurring. Also no ETA has been logged for the issue being reported. I do feel for you since I now understand more the SEO issues it can cause. I myself will keep an eye out for the bug report and see if any progress is being made any info outside of this I will email you directly. Thanks. Issue being Experienced: Domains that are set to Go Daddy forwarding IPs may sometimes resolve to a url that has extra characters appended to the end of them. Example: domain1.com forwards to http://www.domain2.com/TLYEZ. However it should just forward to http://www.domain2.com. I think this answers what some Moz users may have been experiencing sporadically, especially this previous thread: https://moz.com/community/q/forwarded-vanity-domains-suddenly-resolving-to-404-with-appended-url-s-ending-in-random-5-characters. My question: Given everything stated above and what we know about the impact of redirect chains on SEO, how severe should I rate this? I told my Director that I would recommend we move away from GoDaddy (something I don't want to do, but feel we _**have **_to do), but she viewed it as just another technical SEO issue and one that didn't necessarily need to be prioritized over others related to the relaunch. How would you respond in my shoes? On a scale of 1 to 10 (10 being the biggest), how big of a technical SEO is this? Would you make it a priority? At the very least, I thought the Moz community would benefit from the GoDaddy confirmation of this issue and knowing about the lack of an ETA on a fix. Thanks!

              Does removal of internal redirects(301) help in SEO

              I am planning to completely remove 301 redirects manually by replacing such links with actual live pages/links. So there will be no redirects internally in the website. Will this boost our SEO efforts? Auto redirects will be there for incoming links to non-existing pages. Thanks, Satish

              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,

              How do you 301 redirect URLs with a hashbang (#!) format? We just lost a ton of pagerank because we thought javascript redirect was the only way! But other sites have been able to do this – examples and details inside

              Hi Moz, Here's more info on our problem, and thanks for reading! We’re trying to Create 301 redirects for 44 pages on site.com. We’re having trouble 301 redirecting these pages, possibly because they are AJAX and have hashbangs in the URLs. These are locations pages. The old locations URLs are in the following format: www.site.com/locations/#!new-york and the new URLs that we want to redirect to are in this format: www.site.com/locations/new-york We have not been able to create these redirects using Yoast WordPress SEO plugin v.1.5.3.2. The CMS is WordPress version 3.9.1 The reason we want to 301 redirect these pages is because we have created new pages to replace them, and we want to pass pagerank from the old pages to the new. A 301 redirect is the ideal way to pass pagerank. Examples of pages that are able to 301 redirect hashbang URLs include http://www.sherrilltree.com/Saddles#!Saddles and https://twitter.com/#!RobOusbey.

              Can an incorrect 301 redirect or .htaccess code cause 500 errors?

              Google Webmaster Tools is showing the following message: _Googlebot couldn't access the contents of this URL because the server had an internal error when trying to process the request. These errors tend to be with the server itself, not with the request.  _ Before I contact the person who manages the server and hosting (essentially asking if the error is on his end) is there a chance I could have created an issue with an incorrect 301 redirect or other code added to .htaccess incorrectly? Here is the 301 redirect code I am using in .htaccess: RewriteEngine On RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/.]+/)*(index.html|default.asp)\ HTTP/ RewriteRule ^(([^/.]+/)*)(index|default) http://www.example.com/$1 [R=301,L] RewriteCond %{HTTP_HOST} !^(www.example.com)?$ [NC] RewriteRule (.*) http://www.example.com/$1 [R=301,L] Could adding the following code after that in the .htaccess potentially cause any issues? BEGIN EXPIRES <ifmodule mod_expires.c="">ExpiresActive On
              ExpiresDefault "access plus 10 days"
              ExpiresByType text/css "access plus 1 week"
              ExpiresByType text/plain "access plus 1 month"
              ExpiresByType image/gif "access plus 1 month"
              ExpiresByType image/png "access plus 1 month"
              ExpiresByType image/jpeg "access plus 1 month"
              ExpiresByType application/x-javascript "access plus 1 month"
              ExpiresByType application/javascript "access plus 1 week"
              ExpiresByType application/x-icon "access plus 1 year"</ifmodule> END EXPIRES (Edit) I'd like to add that there is a Wordpress blog on the site too at www.example.com/blog with the following code in it's .htaccess: BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On
              RewriteBase /blog/
              RewriteRule ^index.php$ - [L]
              RewriteCond %{REQUEST_FILENAME} !-f
              RewriteCond %{REQUEST_FILENAME} !-d
              RewriteRule . /blog/index.php [L]</ifmodule> END WordPress Thanks

              Too many 301 redirects?

              Hey, My company currently has one chief website with about 500-600 other domains that all feature the same material as the chief website.  These domains have been around for about 5 years and have actually picked up some link traffic. I have all of these identical web-pages utilizing rel=canonical but I was wondering if I would be better served, from SEO purposes, to 301 redirect all of these sites to their respective pages on our chief website?  If I add 500 301 redirects, will the major search engines consider this to be black-hat link-building even though the sites are related and technically already feature the same content? For an example, the chief website is www.1099pro.com and I would 301 redirect the below sites to the chief site: 1099softwarepro.com 1099softwarepro.info 1099softwarepro.net 1099softwarepro.biz 1099softwareprofessionals.com 1099softwareprofessionals.info ...you get the point

              301 or 302 Redirects to Mobile Site

              When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here? Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?

              Are there any negative effects to using a 301 redirect from a page to another internal page?

              For example, from http://www.dog.com/toys to http://www.dog.com/chew-toys. In my situation, the main purpose of the 301 redirect is to replace the page with a new internal page that has a better optimized URL. This will be executed across multiple pages (about 20). None of these pages hold any search rankings but do carry a decent amount of page authority.
