Web Marketing is not on Two Domains only
Traditional Web Marketing in recent years maintains the practice that the scope of a program is often on two domains only. This would include the domain of the corporation (example: company.com) and that search engine we all use (google.com)
Domain One: “www.anycompany.com”
Web Marketing departments often focus on building out product and solution pages, industry accolades, and a pumping of news from press releases or other timely information.
