cross sub-domain behavior: PV/Visit, Bounce%

[H_L]

Hi there,

I got a question about cross sub-domain visit, generally speak:

Will cross sub-domain visit being counted as "Bounce"?

Background:

There are 2 sub-domains:

1.domain.com,

2.domain.com,

both tracking under same report suite: domainglobal

Recently, it's interested to see the PV/Visit is getting lower on 1.domain.com, but Bounce% is also lower.

in 1.domain.com, there is a button, once user click, will be direct to 2.domain.com, and the tracking is "Click" on 1.domain.com, but not PV

So, the question comes:

as in the first screen shot, the PV/Visit and Bounce% are only counted for 1.domain.com, will this be the reason of both down going PV/Visit and Bounce%?

There is another additional question:

On the other hand, IF there is no tracking "Other Click" for the click in 1.domain.com, will it be a bounce? (since after clicking, the PV is under 2.domain.com but not 1.domain.com)

This question was asked here, but didn't understand...., coz it's said "Bounce Rate is Calculated", but then followed by "there were 2 pages under single domain"....If it's 2 pages under 1 domain, then the bounce rate is NOT calculated...is it?

Thanks in advance for your inputs.

Have a good day.
