Welcome to the Q&A Forum

We are in the process of completely rebuilding our web presence.  We went ahead and started a blog using Hubspot while we are redesigning everything and writing all new content.  The new site will be live in early August.  The question is when do we start making a big push with Linkbuilding?  I am currently trying to promote the Blog but I'm wondering about linkbuilding for the rest of the site?  Do we wait until the new site is live or do we start doing it now?  The new site will be completely different from the old site?
