How can you promote a sub-domain ahead of a domain on the SERPs?

[nathangdavidson2]

I have a new client that wants to promote their subdomain uk.imagemcs.com and have their main domain imagemcs.com fall off the SERPs.

Objective? Get uk.imagemcs.com to rank first for UK 'brand' searches.

Do a search for 'imagem creative services' and you should see the issue (it looks like rules have been applied to the robots.txt on the main domain to exclude any bots from crawling - but since they've been indexed previously I need to take action as it doesn't look great!).

I think I can do this by applying a permanent redirect from the main domain to the subdomain at domain level and then no-indexing the site - and then resubmit the sitemap.

My slight concern is that this no-indexing of the main domain may impact on the visibility of the subdomains (I'm dealing with uk.imagemcs.com, but there is us.imagemcs.com and de.imagemcs.com) and was looking for some assurance that this would not be the case. My understanding is that subdomains are completely distinct from domains and as such this action should have no impact on the subdomains.

I asked the question on the Webmasters Forum but haven't really got anywhere

Can anyone suggest a course of action?

many thanks,

Hi there,

Yeap, subdomains are different sites to google from the root domain.

What you are willing to do is to non index the root domain.
Of course one way is to make a 301 redirect, if you still want to preserve the root domain visible I'd do these steps:
1. Set canonical tag in the home to the sudomain
2. Set meta robots tag to noindex in the root domain
3. Update the sitemap, leaving only what you want in the root domain. Update in SC.
4. Create a SC profile for the subdomain, create a sitemap and upload it to SC.
5. Wait

Hope I've helped.
Best luck.
GR.
