We built a new website for one of our clients. Covering services A B C mostly commercial and industrial B2B construction service. We bought him a brand new domain called serviceAcompanyname.com The website uses a brand new domain and as no DA and PA yet.
The client wants a new section added to the Website concerning a new service ( we are going to call it service D) which is still a local service but offered to Home owners.
Should we buy a new domain called serviceD-region-companyname.com and make a microsite covering the topic and work on backlinks and links in parallel for both sites, or would we be better off just adding a new section to the existing website and work on the main DA.
Will it be easier in the future to enhance 2 different domains or a single one even though all services are not targeting the same audience.
