Site migration/ CMS/domain site structure change-no access to search console
-
Hi everyone,
We are migrating an old site under a bigger umbrella (our main domain). As mentioned in the title, We'll perform CMS migration, domain change, and site structure change. Now, the major problem is that we can't get into google search console for the old site. The site still has old GA code, so google search console verification using this method is not possible, also there is no way developers will be able to add GTM or edit DNS setting (not to bother you with the reason why). Now, my dilemma is :
1. Do we need access to old search console to notify Google about the domain name change or this could be done from our main site (old site will become a part of) search console
2. We are setting up 301 redirects from old to the new domain (not perfect 1:1 redirect ). Once migration is done does anything else needs to be done with the old domain (it will become obsolete)?
3.The main site, Site-map... Should I create a new sitemap with newly added pages or update the current one.
4. if you have anything else please add:)
Thank you!

If your architecture is changing, (e.g: from non-www to www, then from HTTP to HTTPS) - just be careful that your developer's logic doesn't start 'stacking' redirect rules
You want to avoid this:
A) user requests http://oldsite.com/category/information
B) 301 Redirect to - http://newsite.com/category/information
C) 301 Redirect to - https://newsite.com/category/information
D) 301 Redirect to - https://www.newsite.com/category/information
Keep your redirects **strictly origin to final destination, and you'll probably be ok! **In the case of my example the redirect should go straight from A to D, not from A to B (hope that makes sense)
Install this Chrome extension so that you can see redirect paths in your Chrome extension buttons menu. It's very, very handy for testing redirects

Thank you for a detailed response.
It's a second scenario. Domain/hosting will stay stays for old domain and all redirects will point to relevant destination pages in our main website. We already performed a massive hybrid migration (main site ) that delivered a CMS change, site structure/URL change and content cut without losing any traffic (we actually gained north of 30% increase in post-migration period). Migration was done over 3 month period and it was done right. This time, the project was conceived and nearly finished in the bubble and got into my attention way too late.

You wanna' be really careful here. From the sounds of it you had a collection of 'web pages' under an old umbrella site (which contains loads of other stuff too) and you are 'extracting' those web pages and turning them into a new website. For most intents and purposes, a domain 'is' a website
If the old site is staying live with other stuff still on it, and only part of it is migrating - obviously you DON'T want to tell Google that the whole umbrella site is 'becoming' a much narrower site on a new domain. That's inaccurate information, and will kill off the main site's performance
Another issue. Currently your 'site section' which will become its own site, is receiving SEO authority through the main domain's backlinks, then transferred through the internal link structure. If the old site is staying live, most of it won't be redirected to the new 'extract' site. The internal linking from the main site will also be gone, which means a performance reset for those section of URLs is quite darn likely
There is some potential, that I got this exactly the wrong way around. Maybe you are saying that a previously external site is coming 'under' the big umbrella. That would be much easier to deal with!
In this second scenario, yes I'd recommend telling Google that one whole domain is becoming part of another domain using the domain migration tool within search console. I have seen migration projects succeed without this, but I've also seen Google's algos throw wobblies so... Yeah, I'd say do it to be safe
The old domain needs to still exist, with a hosting package - in order to perform your redirects. Redirects are handled by the .htaccess or web.config file(s) and they need hosting to live on. Without it, all your redirects will die. If you don't keep the redirects live for 6-12 months, prepare to lose some SEO authority as it won't have all translated across by then
Your new pages, regardless of whether they are on an external or internal domain, should be listed in an XML sitemap. Wherever they are moving to, that domain's XML sitemap needs to have the newly spawned URLs in
Hope that helps

Why do sites w/o structured data beat me for rich snippets?
I can't figure this out. For a number of search terms that I compete for, there are competitors that rank below me, but their pages are featured in a rich snippet. I wanted to see what kind of structured data these sites are providing, thinking maybe there's something I can learn. But when I run these URLs through Google's Structured Data Testing Tool, it tells me these pages contain no structured data! So how is it that Google think's my page is more relevant (I rank higher) and I have structured data, but Google chooses to feature a different page? Does anyone have ideas on how I can snag these rich snippets for myself?

Top-10 ranked site dropping in/out of Google index?
I work for a company that makes an important product in a category. The company has a website (www.company.org); the product is at www.company.org/product. We recently (early May) redesigned and rearchitected the product site for SEO purposes. The company site talks about the category a bit (imagine the Colgate site; it talks about "toothpaste" a bit). The blog (blog.company.org/product) also talks about the category quite a bit (and links to the company site of course). The product is a major product in the category, among the top 3. The site and blog have been around for 15+ years. The site has appx. a billion backlinks, most branded links to the product. It's in the top 50 highest ranked sites among all sites on the internet in the ahrefs rank index. Imagine you are searching for our product category, "category". If you search for "category" in Bing today, my company's site is the 3rd result, and it's the 1st result from a company that makes a product in this category. If you search for "category" in Google today, our site is not in the top 150 results. In fact, the site keeps dropping out of Google's index. (See attached for what that looks like in the search console.) What might cause a site to jump from "ranked in top 10" to "not ranked" in Google -- back and forth every couple of days? Penalties? Our recent (early May) site rearchitecture? We're not making giant, index-shifting changes every day. wE0Bn

Sub Domain or New Domain?
Hi All, We have a client that has a business with three different services. 2 of these services compliment each other in a really obvious way, but the 3rd, while related is not such a obvious complimentary service. For this reason, service 3 kind of weakens the content of the website SEO wise for the two main services. Also, internally at the business it is run by an entirely different team so it feels culturally somewhat different. So, the client wants to pull all the content about service 3 and put it on a different website. Which would you chose as a domain for this new site: service3.existingdomain.co.uk or www.service3+brandname.co.uk

Migrating a site from a standalone site to a subdivision of large .gov.uk site
The scenario We’ve been asked by a client, a Non-Government Organisation who are being absorbed by a larger government ministry, for help with the SEO of their site. They will be going from a reasonably large standalone site to a small sub-directory on a high authority government site and they want some input on how best to maintain their rankings. They will be going from the Number 1 ranked site in their niche (current site domainRank 59) to being a sub directory on a domainRank 100 site). The current site will remain, but as a members only resource, behind a paywall. I’ve been checking to see the impact that it had on a related site, but that one has put a catch all 302 redirect on it’s pages so is losing the benefit of a it’s historical authority. My thoughts Robust 301 redirect set up to pass as much benefit as possible to the new pages. Focus on rewriting content to promote most effective keywords – would suggest testing of titles, meta descriptions etc but not sure how often they will be able to edit the new site. ‘We have moved’ messaging going out to webmasters of existing linking sites to try to encourage as much revision of linking as possible. Development of link-bait to try and get the new pages seen. Am I going about this the right way? Thanks in advance. Phil

Site dropped rankings when changing host from US to Spain
My site was ranked very well in the UK & US for multiple keywords but we changed hosting from the US to Spain and since then the rankings in the US & UK have dropped between 5 to 35 positions on all keywords and are showing no signs of returning 3 weeks later. What can be causing this? The site was down for about 3 to 5 hours a few days before we transferred hosting (this is why we changed hosting due to the previous hosting being down too often). It does seem as though the new location of the hosting server seems to be affecting rankings but I need confirmation on this or any other ideas why the rankings may have dropped. Thanks in advance

Our site is recieving traffic for both .com/page and .com/page/ with the trailing slash.
Our site is recieving traffic for both .com/page and .com/page/ with the trailing slash. Should we rewrite to just the trailing slash or without because of duplicates. The other question is, if we do a rewrite, google has indexed some pages with the slash and some without - i am assuming we will lose rank for one of them once we do the rewrite, correct?

WWW vs Non-WWW/Moving a site to a new CMS/Redirect all of the previous URLs
We are working on a new design for a website, which is currently on a CMS that has non-seo-friendly URLs. There is no redirection of 'www' to non-www or vice versa, or handling of homepage redirection so there is only one instance of 'home'. To move the site in the future, all of these URLs will have to be redirected to their new, and I hope, seo-friendly counterparts. Is it prudent now to redirect the four home page links so there is only one? and to redirect all non-www to 'www' so there is only one instance of each page? Or should I leave it and redirect all of them when the time comes?
