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!

Technical Site Migration
Hello All- I have been in the SEO industry for about 4 years and feel fairly confident in my technical SEO; however, I am being asked to conduct a migration that is both a platform change (step 1) then a consolidation change (think of combining websites when a company is acquired) all within a 4-5 month time span. I feel like as I begin to create this multi-step checklist I would love to hear of others that have gone through something similar or have resources you could point me to form more of a process/procedure standpoint. Again - I feel confident in the technical output but I have a fairly junior team and want to execute this smoothly. Feel free to add recommendations or ask for clarification if my discussion question doesn't make sense.

I need help on how best to do a complicated site migration. Replacing certain pages with all new content and tools, and keeping the same URL's. The rest just need to disappear safely. Somehow.
I'm completely rebranding a website but keeping the same domain. All content will be replaced and it will use a different theme and mostly new plugins. I've been building the new site as a different site in Dev mode on WPEngine. This means it currently has a made-up domain that needs to replace the current site. I know I need to somehow redirect the content from the old version of the site. But I'm never going to use that content again. (I could transfer it to be a Dev site for the current domain and automatically replace it with the click of a button - just as another option.) What's the best way to replace blahblah.com with a completely new blahblah.com if I'm not using any of the old content? There are only about 4 URL'st, such as blahblah.com/contact hat will remain the same - with all content replaced. There are about 100 URL's that will no longer be in use or have any part of them ever used again. Can this be done safely?

How much does URLs with CAPS and URLs with non-CAPS existing on an IIS site matter nowadays?
I work on a couple ecommerce sites that are on IIS. Both sites have return a 200 header status for the CAPS and non CAPS version of the URLs. While I suppose it would be ok if the canonicals pointed to the same version of the page, in some cases it doesn't (ie; /Home-Office canonicalizes to itself and /home-office canonicalizes to itself). I came across this article (http://www.searchdiscovery.com/blog/case-sensitive-urls-and-seo-case-matters/) that is a few years old and I'm wondering how much of an issue it is and how I would determine if it is/isn't?

Switching Url
I started working with a Roofer/Contractor about a year ago. His website is http://www.lancasterparoofing.com/. The name of his business is Spicher Home Improvements. He used to have spicherhomeimprovements.com, well he still does. He was focusing on Roofing and Siding but now would like to branch to other areas like Interior remodeling. So adding interior work under LancasterPaRoofing.com is not applicable. I do not think starting another domain and having two is the best option. I think he should go back to using SpicherHomeImprovements.com and I assume he would take a small hit but in time he should be better off. Plus the url is more applicable to the real name of his business. Thanks for any feedback I receive. Chad

301 forwarding old urls to new urls - when should you update sitemap?
Hello Mozzers, If you are amending your urls - 301ing to new URLs - when in the process should you update your sitemap to reflect the new urls? I have heard some suggest you should submit a new sitemap alongside old sitemap to support indexing of new URLs, but I've no idea whether that advice is valid or not. Thanks in advance, Luke

URL tracking on offline material
Hi there, Hope someone can give some advice. We are doing some magazine advertising, the main purpose of the advert is to promote one of our new products, however the URL goes something like this: http://www.domain.com/products/new-product-libra-furniture/ which is just too long for anyone to remember, I think it should be simply domain.com/libra which redirects to the product page, however how can I track this in Google Analytics? if using a 301 that's impossible? Any advice would be grateful.

URL language on Global Sites
Has anyone looked into a page not ranking as well because the URL is in English when the subdomain is geared for a different country and different language? I can defiantly see this taking away from the user experience, but didn't know if there was any concrete evidence or case studies that would show if it is a big deal or not for rankability? I know this is a backwards question to begin with because the priority over rankability is always UX, but there may not be a way to fix it unless I can prove it is a big deal.

URL Error or Penguin Penalty?
I am currently having a major panic as our website www.uksoccershop.com has been largely dropped from Google. We have not made any changes recently and I am not sure why this is happening, but having heard all sorts of horror stories of penguin update, I am fearing the worst. If you google "uksoccershop" you will see that the homepage does not rank. We previously ranked in the top 3 for "football shirts" but now we don't, although on page 2, 3 and 4 you will see one of our category pages ranking (this didn't used to happen). Some rankings are intact, but many have disappeared completely and in some cases been replaced by other pages on our site. I should point out our existing rankings have been consistently there for 5-6 years until today. I logged into webmaster tools and thankfully there is no warning message from Google about spam, etc, but what we do have is 35,000 URL errors for pages which are accessible. An example of this is: | URL: | http://www.uksoccershop.com/categories/5_295_327.html | | Error details In Sitemaps Linked from Last crawled: 6/20/12First detected: 6/15/12Googlebot 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. Is it possible this is the cause of the issue (we are not currently sure why the URL's are being blocked) and if so, how severe is it and how recoverable?If that is unlikely to cause the issue, what would you recommend our next move is?All help is REALLY REALLY appreciated 🙂
