In a Google Webmaster Hangout, Google’s John Mueller mentioned splitting or merging websites. He outlined the difficulties and what internet publishers can do to be certain that rating alerts move. He additionally defined why merging web sites doesn’t assure a merging of the site visitors.

Transferring Sites is Straightforward

John Mueller said that shifting an internet site from one area to one other area is straightforward for Google to take care of. It’s been my expertise that shifting a web site from domains, sub-domains and shifting a number of hundred thousand pages and pictures to a renamed folder can go easily. In my expertise it took just a few weeks for Google to kind all of it out.

Google’s John Mueller discussing the difficulties involved in site migrations and how to successfully combine websites.

Google’s John Mueller discussing the difficulties concerned in web site migrations and the way to efficiently mix web sites.

John Mueller noticed:

“Transferring websites is usually loads simpler as a result of we are able to move all the alerts one to one.”

His comment about passing alerts one to one is necessary. This remark holds true with redirecting outdated URLs to new URLs and even with canonicals. One of the vital widespread errors I see is redirecting URLs to the house web page. That’s a positive method to waste your rating alerts in addition to present a poor person expertise.

John Mueller lately affirmed how to pass 100% of PageRank with a 301 redirectand it concerned a straight one to one matching of contact.

John Mueller additionally affirmed easy web site transfer is simpler to debug:

“It’s loads simpler for us to debug as effectively if one thing goes incorrect. Somebody can take a look at it and say… that is the outdated state and that is the brand new state and we are able to examine that.”

Splitting or Merging Sites and Google

John Mueller famous that splitting one web site into a number of websites is sophisticated. The complication derives in how the hyperlink and rating alerts will migrate to the brand new websites.

Many websites are created with interlinking components. There are hyperlinks from the house web page, from sitewide navigation and contextually from particular person pages.

As soon as a web site is break up into particular person web sites, these interconnections are typically misplaced. The interlinking may be retained however that generally defeats the aim of splitting one web site into particular person websites.

Right here’s what John Mueller stated:

“Splitting and merging websites is at all times actually tough for us. …for those who’re splitting or merging websites then there’s no actually clear and effectively outlined new and outdated state.

They’re not likely mapped one to one there since you’re taking one web site and turning it into 5 and it’s a very totally different state of affairs for every of these particular person websites.

In order that’s one thing that takes loads longer to be processed and errors they have an inclination to be extra seen I’d say as a result of it’s like we’ve got to reprocess the whole lot.

And if there’s a mistake in there…”

Combining Web sites is Troublesome

John Mueller noticed that the identical issues exist when combining a number of web sites right into a single web site. There’s a lot that wants to be thought of. For instance, legacy 301 redirects can complicate combining a number of web sites.

Right here’s what Google’s Mueller stated:

“…You could have the identical state of affairs for those who take a number of websites and also you merge them into one web site. That’s such as you at all times run into that as effectively.”

Combining Web sites and Elevated Site visitors

An fascinating remark about combining web sites is that the consequence isn’t at all times extra site visitors. One would assume that combining two web sites into one will end in a web site with the mixed power of the mixture. However John Mueller stated that’s not at all times the case:

“You could have like 5 websites it’s like what’s the remaining state? You may’t say like add all of them up and that’s the site visitors you’d get. It’s primarily inconceivable to guess forward of time and the way lengthy it takes.”

How to Successfully Mix Web sites

Google’s John Mueller stated that the best way to efficiently merge a number of websites right into a single web site is to deal with matching outdated legacy pages to new internet pages which might be as related as doable.

John Mueller stated:

“I believe it’s simply necessary to additionally guarantee that… from a content material standpoint you additionally ensure you have one thing that matches the outdated content material.

In order that people who find themselves explicitly searching for their outdated stuff they are going to have some place to go.”

He didn’t verify that 100% of the PageRank and different alerts will move. However it appears that evidently getting as shut to a one to one match is a greatest follow to comply with. And for those who’re searching for a site visitors enhance from combining websites, in accordance to John Mueller it’s not one thing that may be counted on.
