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.

301 Redirects to relative URLs not absolute a problem?
Hi we recently did a migration and a lot of content changed locations see: https://d.pr/i/RvqI81 Basically, the 301 goes to the correct location but its a relative URL (as you can see from the screenshot) rather than absolute URL. Do you think this is a high priority issue from an SEO standpoint, should we get the developer to change the redirects to absolute? Cheers.

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

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.

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
Intermediate & Advanced SEO | | ajarad
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.

.htaccess 301 Redirect Help! Specific Redirects and Blanket Rule
Hi there, I have the following domains: OLD DOMAIN: domain1.co.uk NEW DOMAIN: domain2.co.uk I need to create a .htaccess file that 301 redirects specific, individual pages on domain1.co.uk to domain2.co.uk I've searched for hours to try and find a solution, but I can't find anything that will do what I need. The pages on domain1.co.uk are all kinds of filenames and extensions, but they will be redirected to a Wordpress website that has a clean folder structure. Some example URL's to be redirected from the old website: http://www.domain1.co.uk/charitypage.php?charity=357 http://www.domain1.co.uk/adopt.php http://www.domain1.co.uk/register/?type=2 These will need to be redirected to the following URL types on the new domain: http://www.domain2.co.uk/charities/ http://www.domain2.co.uk/adopt/ http://www.domain2.co.uk/register/ I would also like a blanket/catch-all redirect from anything else on www.domain1.co.uk to the homepage of www.domain2.co.uk if there isn't a specific individual redirect in place. I'm literally tearing my hair out with this, so any help would be greatly appreciated! Thanks

Merging Sites: Will redirecting the old homepage to an internal page on the new site cause issues?
I've ended up with two sites which have similar content (but not duplicate) and target similar keywords, rather than trying to maintain two sites I would like to merge the sites together. The old site is more of a traditional niche site and targets a particular set of keywords on its homepage, the new site is more of an authority site with a magazine type homepage and targets the same set of keywords from an internal page. My question is: Should I redirect the old site's homepage to the relevant internal page on the new website...
Intermediate & Advanced SEO | | lara_dar
...or should I redirect the old site's homepage to the new site's homepage? (the old site's homepage backlinks are a mixture of partial match keyword anchor text, naked URLs and branded anchor text) I am in two minds (a & b!) (a) Redirecting to the internal page would be great for ranking as there are some decent backlinks and the content is similar (b) But usually when you do a 301 redirect the homepage usually directs to the new homepage and some of the old site's links are related to the domain rather than the keyword (e.g. http://www.site.com) and some people will be looking for the site's homepage. What do you think? Your help is much appreciated (and hope this makes sense...!)0 -
