Why Is Domain Strategy Important for SEO?
Domains build search power. For most companies, this involves building as much equity and strength for their core domain as possible (www.domain.com). If a company ends up having twelve separate domains, all focused on the same vertical or subject matter, then it can be splitting its search strength across those domains...

For example, let?s say the twelve domains I mentioned above (all focused on the same vertical) each have 5,000 pages indexed and 12,000 inbound links. They all have low to moderate SEO power and each is struggling to rank for target keywords. Imagine you were able to combine those domains and organize them in logical subdirectories (where you can silo content by category). Then you would have 45,000 pages indexed and 25,000 inbound links for one domain. You can start to build more strength in the core domain and leverage all of your valuable content to build traffic, links, and ultimately more search power (and better rankings)....

... I?m not saying to always have just one domain (especially if you?re a large company that focuses on several verticals or has multiple brands). But, don?t have 15 domains per brand, 250 domains for marketing campaigns, or 300 subdomains for random purposes.
