Transfering newly created targeted landing pages on an existing domain to a new domain

[McCannSEO]

Hi - Hope someone can help me with this please

I have a question regarding if its possible or advisable to create and host targeted landing pages and a blog on an existing domain, and then move these pages only to a brand new domain?

The existing site has good authority and is established. Due to tight timescales in delivery I suggested creating specific landing pages and installing a blog to build authority and trust over time to target completely new keywords. Also the new pages will be helped by the existing domain authority.

I've just found out client may want a whole new site, complete with new branding etc and completely new domain in time.

Has anyone experienced migrating specific pages and a blog across to a completely new domain and leaving the existing site as it was.  I have a whole host of concerns over this, but the main one is that I will be building relationships and content to landing pages and the blog, aswell as linking out etc and then these URL's will have a re-direct on them, going to a completely new domain.
Also, the existing domain could lose any authority gained as although I wont only be targeting these pages, these will be the main ones being optimised and this will look unnatural. Do I?

A./ Create blog and new landing pages on existing domain eg - www.testing.com/blog
www.testing.com/new-landing-pages, and then migrate these across to a brand new domain.

or

B./ Create the new landing pages and blog and leave them on the existing domain - period? Concerns here;
Client wants to re-vamp and have a new style and these pages will not necessarily be supported by the existing site, there is no guarantee that we are even allowed to create new pages, let alone internal linking.

or

C./ Bite the bullet and simply suggest a brand new domain to start with and explain the timescales and its either complete new domain or work on existing one.

If anybody else has any other ideas I would really appreciate them. The client is re-branding and the company who host the existing domain, might not want to support the new pages and blog.

I was hoping to provide a short term and long term solution as a brand new domain will take time to build up, especially as they are also brand new keywords we are targeting. However, I dont want the existing domain to be hit with any penalties or flag anything un-natural to Google.

Many thanks in advance for any advice..

I don't understand..

The client wants a new site, new domain, and a re-branding.. why wouldn't they/you move their existing established name and brand entirely over to the new site/new brand with a site-wide 301? They want to keep both brands alive? I can't imagine a scenario where this is a good idea. a re-branding is a re-branding. Ask Moz!

Where is my confusing coming from here?

Hi Jesse

Thanks for getting back to me.

The client is launching a new product/service that is different from their existing products, they still want to keep the old site active, but the new products and blog is what is being re-branded and marketed, not the entire site.

Their current site is hosted and built by a different agency and the new product is being marketed by us. We are waiting to see if we can install a blog on their existing domain and it is not hosted by us. The client has not requested a new site, more asked about one.

Originally, before I knew all the history, I suggested landing pages on the existing domain for the short term and then if they still wanted to go ahead with the re-branding and new site then 301 the whole domain. Question on this though, if we don't really need to do a re-direct ie company name not changing, just a re-brand I think it would be a good idea to leave the domain as it is, as it has authority and history. What are your thoughts on this.

I wanted to get feedback to see if anyone else has ever re-directed part of a domain, rather than a whole site as I didn't think it would be a good idea either.

Thanks again for the response

Just a thought  - would a sub domain be a good idea here? So it would look something like; newbrand.testing.com as a sub domain to www.testing.com? This seems to be an alternative if the hosting is an option.

The blog would still be best placed to sit on the main domain, but any thoughts on this would be appreciated.

Thanks (sorry if I am just answering my own question here)
