Short answer is yes. But there are some caveats:
- The urls will all point to the same site, though you can have them point to different parts of the site. For example, mysite.com can point to your home page, and mygirlsite.com can point to /mygirl within that site.
- They will all share the same site resources and admin settings.
- They will share the same analytics
- Keeping the sites organized will likely end up being more of a pain than it is worth.
Thank you Adam.
At the end is better keep all separated.
Depends on the circumstance, but for the most part, yeah, separate is better.
You can have different analytics running if you use google analytics Adam as a note.
While I agree with Adam here is a case that I used one BC account with multiple URLs:
I built a site for a small app company. I built the main company site on BC. Then each app they have also has a page with its own domain. There was no need to create multiple BC accounts for what is essentially a few page site. So I put both under one site and it works well. The site is small so it is easy to manage. Trying to do this with a larger site is much more difficult.
As a note I did add canonical URLs in the page so Google wouldn't index the incorrect pages.
