New Subdomain SEO questions

[leadforms]

I have a main site - mysite.com. I just created a subdomain - leadform.mysite.com

I plan to use the leadform.mysite.com as a 1 page lead form only.

I will link to leadform.mysite.com from mysite.com and also from other websites I own (myothersite.com etc.) - filtering all traffic to this form to capture leads.

(Note - the leadform.mysite.com has CNAME to other server that hosts the backend of the form)

My questions are:

1. How should I link from mysite.com to leadform.mysite.com? With dofollow or nofollow? (mysite.com has 1000's of pages and would link from every page with "get a quote' type button)

2) How should I link from myothersite.com to leadform.mysite.com? With dofollow or nofollow? Any SEO risk linking to leadform.mysite.com from an outside domain? (myothersite.com has 1000's of pages and would link from every page with "get a quote' type button)

3. Does it make sense to build links from outside sites to leadform.mysite.com directly to try to get that lead capture page to rank on it's own?

4) Does it make sense to link back from leadform.mysite.com back to mysite.com for seo value? With dofollow or nofollow?

Thanks in advance for any help.

I have to note, as with any SEO question, the answer is just my opinion and not knowing the full and specific scenario, take it with a grain of sale.

As a general rule in that scenario though I'd simply let the bots do what they will with it but make sure to canonical the page to itself so if the other sub you're CNAMEing gets picked up it canonical's back to the real one.

In essence, let the link weight flow as it will - just make sure you don't get hit with a dup-content issue on the page.

As for ranking ... I'd focus your energies on the main site unless there's a term that the page lends itself to. But then ... that's pretty much a global truth: focus on rankings a page with content that lends itself to the term you want to rank for.

Good luck !!!
