Domain migration strategy
-
Imagine you have a large site on an aged and authoritative domain.
For commercial reasons the site has to be moved to a new domain, and in the process is going to be revamped significantly. Not an ideal starting scenario obviously to be biting off so much all at once, but unavoidable.
The plan is to run the new site in beta for about 4 weeks, giving users the opportunity to play with it and provide feedback. After that there will be a hard cut over with all URLs permanently redirected to the new domain.
The hard cut over is necessary due to business continuity reasons, and real complexity in trying to maintain complex UI and client reporting over multiple domains. Of course we'll endeavour to mitigate the impact of the change by telling G about the change in WMC and ensuring we monitor crawl errors etc etc.
My question is whether we should allow the new site to be indexed during the beta period?
My gut feeling is yes for the following reasons:
-
It's only 4 weeks and until such time as we start redirecting the old site the new domain won't have much whuffie so there's next to no chance the site will ranking for anything much.
-
Give Googlebot a headstart on indexing a lot of URLs so they won't all be new when we cut over the redirects
Is that sound reasoning? Is the duplication during that 4 week beta period likely to have some negative impact that I am underestimating?

I wouldn't sweat it. We left up www.bulwarkpest.com for several months while moving to www.bulwarkpestcontrol.com .... I know that there is some risk in it. But I think Google is pretty understanding of site migrations. Of course I am just a small pest control guy so they may not have ever noticed. Sooo.. take that with a grain of salt.
It's does make it easier to have the other site live so that you can redirect on a per page base and know that it's working. I would rather make sure the redirects are correct and working prior to moving the entire site over. But be warned.. site redirects may not always give you the same authority... research the online Yellow Pages.

My opinion of risk goes up much higher if this is a directory vs a site with original content articles.

Hi Aran, thanks for your response.
My thinking has also evolved a bit and I'm now thinking we ought to exclude the new site until we're ready to cut over as @EGOL suggested.
The critical info I didn't mention before was that there is important client ROI and reporting reasons that we need to ensure that the current site continues to perform right up until the cut over, at which point the 301s will be implemented. The cross domain canonical would address the dupliaction, but would also start to depreciate the current pages prematurely.
The thing that I was underestimating before was the negative impression that the new domain would give Google when it suddenly appeared with 1M+ pages of duplicate content plus no real link profile of its own (until we implement the 301s)...all the hallmarks of a scraper.
Better I think to avoid this by excluding the beta until we cut over, and make sure we prep well for that.

Agreed, though Charles could use canonical tags to tell Google that the new pages are authoritative. This may take a while to be indexed, but should prevent any detrimental effects with duplicate content.
-
Thanks very much for your thoughts. The root of my uncertainty is indeed the way Google in particular is viewing duplciated content today.
What if I told you that the site was a business directory and that the new site would be a big improvement in terms of on page optimization? By which I mean new/different (and much better) page titles and improved internal linking. I mention this only because the new site won't a direct replicar of the old one. Make a difference?
-
I have no factual data on this... just going with my gut....
Based upon how Google is acting these days I would not take chances with having two copies of the same site in the SERPs for an entire month. I would not want to see any pages on the new site filtered for being duplicates.
Most people don't get a new site indexed and those redirected domains normally go fairly well. So, I would be pleased with that and not take chances.
Safety might be better than going for some unknown gain.

Domain migration via Wordpress - organic still 60% down four months later
Hi guys!Almost four months ago I performed a Wordpress domain migration. Three pet-based sites were migrated into a new pet-based one that incorporated them all - the new site is petskb.com and 240 posts were migrated.The site migration was performed via 301 wildcard re-directs using the .htaccess files in the old domains, which are still in place and working. I also used the site move tool in GSC. Afterwards, I performed an audit of the new site to ensure that all the old urls were being re-directed to the new one, which they were (and are). There have been no manual actions reported in GSC.The results have been very poor. A small few of the articles that were in the top 10 moved over and I quickly claimed the same positions in the new site. Most did not though and still sit >100 in the SERP or absolutely nowhere (or even omitted) using the main keyword.I've created about 60 new articles (using the same SEO analysis I did previously) since that time on the new site and not one of them has ranked <100 in all that time, whereas on the old sites they would initially rank somewhere in the top 50 after a couple of days and work their way up over the months. These new posts haven't moved though. The posts that were published on the new site four months ago are still in the exact same position.So, I've created new content, re-submitted the sitemap and manually requested re-indexing of the posts. Nothing has changed. I've hired SEO's and not one has found any problems with my site or how I performed the migration. Clearly there is a problem though. The original posts that were ranking previously and all the new posts have not moved in the SERP. There were a few spammy links pointing to the new domain but nothing significant, I did disavow these though - no more than on the old sites though.As a test, I created a new post on another domain which has no posts with the same long-tail keyword as one that has been on my new site for almost four months. The one I posted on the new domain out-ranked the one on petskb after just two days.Can anyone help? If you can I will personally travel to where you live and buy you several beers.Thanks,Matt

Using a Sub Domain as a Main Domain?
Hi, I'm working on a site at the moment and the sub domain is acting as the main domain. This occurred when the site was redesigned and built on a sub domain for testing but it was never moved to the main domain when it went live (a couple of years ago). So little or no pages are live on domain.com but all on sub.domain.com. It's a large company but they have very poor rankings. Would you recommend that they move the sub domain back into the root folder? Does this involve renaming/re-pointing URLs? Thanks Louise

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Community inside the domain or in a separate domain
Hi there, I work for an ecommerce company as an online marketing consultant. They make kitchenware, microware and so on. The are reviewing their overall strategy and as such they want to build up a community. Ideally, they would want to have the community in a separate domain. This domain wouldn't have the logo of the brand. This community wouldn't promote the brand itself. The brand would post content occassionally and link the store domain. The reasoning of this approach is to not interfere in the way of the community users and also the fact that the branded traffic acquired doesn't end up buying at the store I like this approach but I am concerned because the brand is not that big to have two domains separated and lose all the authority associated with one strong domain. I would definitely have everything under the same domain, store and community, otherwise we would have to acquire traffic for two domains. 1. What do you think of both scenarios, one domain versus two? Which one is better? 2. Do you know any examples of ecommerce companies with successful communities within the store domain? Thanks and regards

SEO value in multiple backlinks from same domain and from various sub-domains.
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu

Move webshop domain to the brand domain?
Hello, A client of mine has a brand with a website for over 10 years now.
Intermediate & Advanced SEO | | Seeders
About 4 years ago the have opened a webshop on an other domain (like www.brandnamewebshop.com). At this moment the brand domain has a seomoz authority of 45.
The webshop domain authority is 25. The question:
Would it not be better to transfer the webshop to the brand domain because of the domain authority? If so, how can this be done the best way? With a 301?
I also think: what a loss of energy of building the authority on the other domain.
Is it an idea to use both domains for a webshop and rewrite the content? Or is there an other way to still make use of the built up domain authority? Would it really help the other domain when I make a 301 redirect (and make use of the pointing links to the webshop domain?). I hope somebody have some experience with this...
Looking forward to the possibilities! Gerjan0 -
