Landing Pages: New Domain or Sub Folder?

[homebizsmart]

I use premise for landing pages.

I have some extra domain names that are fantastic in my industry.

I'm wondering if I should use those domains for these landing pages?

The header, nav, footer, would be the same as my main site,  the body and content would be totally different.

will google penalize me if I have the same header and footer on a landing page?

If you think people may link to these landing pages, you'd be better off putting them on your main domain, so these pages help contribute to your main domains rank.  Generally it's better to put quality pages on your domain, instead of putting landing pages on these extra domains, and pointing them to your site.  It doesn't sound like your extra domains will have much pagerank to pass to your main domain.

Also, more importantly (for me at least), it would be strange to arrive at a landing page, and click a nav link, and arrive at a completely different domain that uses the same nav/header/footer.  I'd feel like there was some spoofing going on...

I'd just set up these extra domains to 301 redirect to my main domain, and leave it at that.

As John mentioned page rank will be minimal and new domains won't have much domain rank either (likely a lot less than your main established domain) if you're wanting them for organic search purposes.

Unless you're wanting to keep building upon the domain and establish them as more than 'one off' landing pages (link building etc) then using them over your main domain wont do you much good short term or long.
