The process that you might follow is that you write some form of content, perhaps a blog, and in that content, you put at least one call-to-action. Once your reader clicks on the call-to-action, he or she will eventually arrive at your contact page. That page should be perfectly suited to your needs.
The Contact page is an extremely valuable aspect of your website and you may feel that it is working well for your business but it may actually not be working well as all. However, there are ways to make improvements.
A large (and early part) of your professional process that eventually leads to greater success and higher revenue is lead generation. Once you have taken those leads and converted them into clients (eventually), you need to maintain the relationships that you have formed with those clients.
