We have an existing large site with strong, relevant traffic, including excellent SEO traffic. The company wants to launch a new business offering, specifically targeted at the "small business" segment. Because the "small business" customer is substantially different from the traditional "large corporation" customer, the company has decided to create a completely independent microsite for the "small business" market. Purely from a Marketing and Communications standpoint, this makes sense. From an SEO perspective, we have 2 options: Create the new "small business" microsite on a subdomain of the existing site, and benefit from the strong domain authority and trust of the existing site. Build the microsite on a separate domain with exact primary keyword match in the domain name. My sense is that option #1 is by far the better option in the short and long run. Am I correct? Thanks in advance!
