I am in charge of my companies website and one of my tasks is to improve SEO. Granted, I am new to this and have been researching for the past 6 months and had an idea. My plan is to build multiple websites and create a huge site using multiple domains. We offer different services and our main home page will have all of the services with links to the other websites which are the individual services so that I don't have to worry about duplicate page content.
www.companyname.com is the main site
www.service#1.com is one of our services
www.service#2.com is another one of our services etc.
Will this have an affect on our SEO in a positive way like I think or would it impact us negatively? and why?
