Google printed a brand new video about web site migrations. John Mueller provided insights into how Google handles web site migrations and the way lengthy they will take. The foremost takeaways are that web site migrations might be tough and {that a} complete plan must be in place earlier than the migration.
The video begins with a query:
“We’re presently going by way of a web site migration and we’d additionally wish to restructure the URLs on the positioning. Does this impose any dangers?”
Migrating a web site usually means altering the area title, generally as a result of the corporate is merged with one other one or as a result of the branding modified.
Becoming a member of two websites collectively are the trickiest as a result of you must select what URLs will stay and which shall be merged into current pages which are related.
John Mueller answered:
“Sadly, whereas this may occasionally at first sound like a small change inside an internet site, it’s not that straightforward for engines like google.
Specifically, engines like google like Google retailer their index on a per-page foundation.
So should you change the deal with or the URL of a web page, that web page’s knowledge needs to be forwarded one way or the other, in any other case it will get misplaced.
It doesn’t matter should you’re fully rebuilding an internet site or should you’re simply eradicating a slash from the tip of URLs. These are all primarily web site strikes.”
John Mueller Presents Web site Migration Ideas
1. Analysis the Choices and Potential Results
Web site strikes might be disruptive so it’s necessary to plan out the transfer by mapping one web site to a different. One technique to do it’s to divide the 2 websites into sections and see if sections can map to one another.
From there it’s a matter of mapping URLs one to 1 and deciding which URLs can’t be moved to the brand new web site and will resolve to a 404 response, which might be powerful if there are hyperlinks pointing to these pages. Which is why it’s necessary to plan forward, totally.
Mueller suggested:
“Since these adjustments take time and have rating results, it’s additionally really helpful to contemplate the timing of once you make a transfer.”

2. Create a Listing of Outdated and New URLs
This is a crucial step.
In keeping with John:
“…This tip will assist allow you to to trace and examine the adjustments afterward.”
An excellent follow is to create a spreadsheet of URLs, which may simply be accomplished with Screaming Frog.
When you’ve obtained the redirects in place and the brand new URLs up, you possibly can examine the work by importing the listing of the previous web site construction to Screaming Frog in order that it may crawl the URLs.
That is simply accomplished by choosing Mode > Listing then clicking on the Add drop down menu tab and choosing the kind of file being uploaded.
Screaming Frog will crawl the previous URLs within the listing and present you which ones URLs are redirecting to the brand new URLs and which aren’t and returning a 404 web page not discovered error response code.
The 404 URLs will be the URLs that didn’t make it over to the brand new web site (in the event that they aren’t the URLs deliberate on being purposely dropped).
You’ll have to find out if the 404 is the proper response (you meant to try this) or if the URL was unintentionally omitted of the positioning migration and must be mapped to a brand new URL.
3. Implement the Migration
Mueller suggested:
“301 redirect all of the previous URLs to the brand new ones, additionally replace all inner mentions corresponding to:
- hyperlinks
- varieties
- structured knowledge
- sitemaps
- and the Robots.txt file”
4. Monitor the Migration
Mueller suggested utilizing Search Console for this:
“Test all pages for the redirect. In Google’s search console report you must see a fast change for an important pages after which a slower change as our techniques reprocess the remaining.”
Mueller cautioned that this final half can take months to complete. He’s talked about how figuring out total web site high quality can take months. Google has to mainly be taught what a web site is about, together with web site high quality and to grasp the place the positioning suits inside the Web.
John really helpful leaving the redirects in place for a minimum of one yr.
In my expertise, it could be obligatory to contemplate leaving the redirects in place for longer than a yr. The reason being as a result of previous URLs which have hyperlinks from different websites pointed at them will develop into damaged hyperlinks if the redirects are eliminated.
You’ll be able to create an outreach to contact websites which are linking to you and ask them to repair the hyperlinks to level to the modified URLs.
However you must remember that doing this type of outreach can backfire as a result of some websites, for a lot of causes, could determine to take away the hyperlink altogether.
Additionally, there could also be hyperlinks on the market that you just don’t learn about, so you possibly can by no means make sure that you had all of the inbound hyperlinks up to date. So for that cause, it could be essential to maintain these redirects in place and be able to replace them ought to a few of the URLs change once more, to keep away from creating chained redirects.
A sequence redirect is when an previous URL redirects to a different previous URL which itself redirects to a different previous URL earlier than it redirects to the ultimate URL. Through the years this will create a series of redirects which turns into problematic for crawling.
Web site Migrations are Powerful
As Mueller suggested, it’s necessary to plan forward. Map related pages collectively and be acutely aware about hyperlink fairness from inbound hyperlinks. Web site migrations may end up in a web site dropping search presence however it doesn’t must occur if it’s preceded with a radical migration plan.
