Google published a caller video astir tract migrations. John Mueller offered insights into however Google handles website migrations and however agelong they tin take. The large takeaways are that tract migrations tin beryllium hard and that a broad program needs to beryllium successful spot earlier the migration.

The video begins with a question:

“We’re presently going done a tract migration and we’d besides similar to restructure the URLs connected the site. Does this enforce immoderate risks?”

Migrating a tract typically means changing the domain name, sometimes due to the fact that the institution is merged with different 1 oregon due to the fact that the branding changed.

Joining 2 sites unneurotic are the trickiest due to the fact that you person to take what URLs volition stay and which volition beryllium merged into existing pages that are similar.

John Mueller answered:

“Unfortunately, portion this whitethorn astatine archetypal dependable similar a tiny alteration wrong a website, it’s not that elemental for hunt engines.

In particular, hunt engines similar Google store their scale connected a per-page basis.

So if you alteration the code oregon the URL of a page, that page’s information has to beryllium forwarded somehow, different it gets lost.

It doesn’t substance if you’re wholly rebuilding a website oregon if you’re conscionable removing a slash from the extremity of URLs. These are each fundamentally tract moves.”

John Mueller Offers Site Migration Tips

1. Research the Options and Potential Effects

Site moves tin beryllium disruptive truthful it’s important to program retired the determination by mapping 1 tract to another. One mode to bash it is to disagreement the 2 sites into sections and spot if sections tin representation to each other.

From determination it’s a substance of mapping URLs 1 to 1 and deciding which URLs cannot beryllium moved to the caller tract and should resoluteness to a 404 response, which tin beryllium pugnacious if determination are links pointing to those pages. Which is wherefore it’s important to program ahead, thoroughly.

Mueller advised:

“Since these changes instrumentality clip and person ranking effects, it’s besides recommended to see the timing of erstwhile you marque a move.”

2. Create a List of Old and New URLs

This is an important step.

According to John:

“…This extremity volition assistance help you to way and cheque the changes afterward.”

A bully signifier is to make a spreadsheet of URLs, which tin easy beryllium done with Screaming Frog.

Once you’ve got the redirects successful spot and the caller URLs up, you tin cheque the enactment by uploading the database of the aged tract operation to Screaming Frog truthful that it tin crawl the URLs.

This is easy done by selecting Mode > List past clicking connected the Upload driblet down paper tab and selecting the benignant of record being uploaded.

Screaming Frog volition crawl the aged URLs successful the database and amusement you which URLs are redirecting to the caller URLs and which are not and returning a 404 leafage not recovered mistake effect code.

The 404 URLs whitethorn beryllium the URLs that didn’t marque it implicit to the caller tract (if they aren’t the URLs planned connected being purposely dropped).

You’ll person to find if the 404 is the close effect (you meant to bash that) oregon if the URL was unintentionally near retired of the tract migration and needs to beryllium mapped to a caller URL.

3. Implement the Migration

Mueller advised:

“301 redirect each the aged URLs to the caller ones, besides update each interior mentions specified as:

  • links
  • forms
  • structured data
  • sitemaps
  • and the Robots.txt file”

4. Monitor the Migration

Mueller advised utilizing Search Console for this:

“Check each pages for the redirect. In Google’s hunt console study you should spot a speedy alteration for the astir important pages and past a slower alteration arsenic our systems reprocess the rest.”

Mueller cautioned that this past portion tin instrumentality months to finish. He’s talked astir however determining wide tract prime tin instrumentality months. Google has to fundamentally larn what a tract is about, including tract prime and to recognize wherever the tract fits wrong the Internet.

John recommended leaving the redirects successful spot for astatine slightest 1 year.

In my experience, it whitethorn beryllium indispensable to see leaving the redirects successful spot for longer than a year. The crushed is due to the fact that aged URLs that person links from different sites pointed astatine them volition go breached links if the redirects are removed.

You tin make an outreach to interaction sites that are linking to you and inquire them to hole the links to constituent to the changed URLs.

But you person to beryllium alert that doing this benignant of outreach tin backfire due to the fact that immoderate sites, for galore reasons, whitethorn determine to region the nexus altogether.

Also, determination whitethorn beryllium links retired determination that you don’t cognize about, truthful you tin ne'er beryllium definite that you had each the inbound links updated. So for that reason, it whitethorn beryllium indispensable to support those redirects successful spot and beryllium acceptable to update them should immoderate of the URLs alteration again, to debar creating chained redirects.

A concatenation redirect is erstwhile an aged URL redirects to different aged URL which itself redirects to different aged URL earlier it redirects to the last URL. Over the years this tin make a concatenation of redirects which becomes problematic for crawling.

Site Migrations are Tough

As Mueller advised, it’s important to program ahead. Map akin pages unneurotic and beryllium conscious astir nexus equity from inbound links. Site migrations tin effect successful a tract losing hunt beingness but it doesn’t person to hap if it’s preceded with a thorough migration plan.
