Welcome to the Q&A Forum

Hi all, I am launching a new website around the end of October and I have purchased a great domain to use for it. My question is should I put some kind of holding page up to try and start building up some domain authority in preperation for launch? Or maybe a blog at www.domain.com/blog and then keep all the blog content at the same location when the full site goes up? Or is it best to wait and just launch the site when the first version is complete? Thanks, Ben
