URL Migration: Better to have .301s processed or 200s?
-
I'm migrating sub-domains to sub-folders, but this question is likely applicable for most URL migrations.
For example: subdomain1.example.com to example.com/subdomain1 and any child pages.
Bear with me as it may just be me but I'm having trouble understanding whether internal links (menu, contextual etc and potentially the sitemaps) should be kept as the pre-migration URL (with .301 in place to the new URL) to give Google a chance to process the redirects or if they should be updated straight away to the new URL to provide a 200 response as so many guides suggest.
The reason I ask is unless Google specifically visits the old URL from their index (and therefore processes the .301), it's likely to be found by following internal links on the website or similar which if they're updated to reflect the new URL will return a 200. I would imagine that this would be treated as a new page, which is concerning as it would have a canonical pointing toward itself and the same content as the pre-migrated URL.
Is this a problem? Do we need to allow proper processing of redirects for migrations or is Google smarter than this and can work it out if they visit the old URL at a later date and put two and two together? What happens in-between? I haven't seen any migration guides suggest leaving .301s in place but to amend links to 200 as soon as possible in all instances.
One thought is I guess there's also the Fetch as Google tool within Search Console which could be used with the old URLs - could this be relied on?
Apologies if this topic has been covered before but it's quite difficult to search for without returning generic topics around .301 redirects.
Hope it makes sense - appreciate any responses!

Hi Amy,
Great question! In our experience, if you're migrating, the best choice is to put 301 temporary redirects in place until Google has the chance to index your new pages.
Be sure to submit all of your new pages to Google Search Console for indexing once migration is complete: https://www.google.com/webmasters/tools/submit-url
Hope this helps!

Should I include URLs that are 301'd or only include 200 status URLs in my sitemap.xml?
I'm not sure if I should be including old URLs (content) that are being redirected (301) to new URLs (content) in my sitemap.xml. Does anyone know if it is best to include or leave out 301ed URLs in a xml sitemap?

URL mapping for site migration
Hi all! I'm currently working on a migration for a large e-commerce site. The old one has around 2.5k urls, the new one 7.5k. I now need to sort out the redirects from one to the other. This is proving pretty tricky, as the URL structure has changed site wide. There doesn't seem to be any consistent rules either so using regex doesn't really work. By and large, the copy appears to be the same though. Does anybody know of a tool I can crawl the sites with that will export the crawled url and related copy into a spreadsheet? That way I can crawl both sites and compare the copy to match them up. Thanks!

Ecommerce Link Juice and Canonical URLs
Hello all. I am optimising an E-Commerce site and I have a questions about Products in several categories & Canonical URL's. Using Magento Platform. site.com/category1/product1/ ( link from category is site.com/product1/ )
Intermediate & Advanced SEO | | s_EOgi_Bear
site.com/category2/product1/ ( link from category is site.com/product1/ )
site.com/category2/subcategory1/product1 ( link from category is the same , as is the canonical URL )
site.com/product1/ ( this is where other categories link to ) Canonical links for all the above is site.com/category2/subcategory1/product1 which takes care of duplicate content correctly. I just wonder if we would get more link juice if ALL the links from all categories went to site.com/category2/subcategory1/product1 ( instead of some going to site.com/product1/ ) Thanks in advance 🙂0 -
More Indexed Pages than URLs on site.
According to webmaster tools, the number of pages indexed by Google on my site doubled yesterday (gone from 150K to 450K). Usually I would be jumping for joy but now I have more indexed pages than actual pages on my site. I have checked for duplicate URLs pointing to the same product page but can't see any, pagination in category pages doesn't seem to be indexed nor does parameterisation in URLs from advanced filtration. Using the site: operator we get a different result on google.com (450K) to google.co.uk (150K). Anyone got any ideas?

What Is The Preferred Url Structure For Se’s?
Here is my issue, my domain is abcdomian.com and I’m trying to rank the site for the keyword “example”. All of my content is under “abcdomain.com/folder/example/” and building content off of “abcdomain.com/example” is not an option. So I’m thinking about moving the content to “abcdomain.com/online-example/” and 301ing the old pages . Of the two paths below, which will have a greater impact on my rankings for the term “example”? Current: abcdomain.com/folder/example/

Capitals in url creates duplicate content?
Hey Guys, I had a quick look around however I couldn't find a specific answer to this. Currently, the SEOmoz tools come back and show a heap of duplicate content on my site. And there's a fair bit of it. However, a heap of those errors are relating to random capitals in the urls. for example. "www.website.com.au/Home/information/Stuff" is being treated as duplicate content of "www.website.com.au/home/information/stuff" (Note the difference in capitals). Anyone have any recommendations as to how to fix this server side(keeping in mind it's not practical or possible to fix all of these links) or to tell Google to ignore the capitalisation? Any help is greatly appreciated. LM.
