Basic knowledge of web marketing techniques.
Basic knowledge of social media platforms.

Perhaps if I can add to your Roadmap one more point that is important and often difficult to handle… that is Client communication skills. It’s all well and good to learn web design but being able to communicate to the client is also fundamentally required. To get the information we need in order to successfully design a site for someone else can be a challenging marathon of email and phone calls that no innocent should be allowed to experience without fair warning – challenging is the polite adjective!

There are of course different dynamics involved in dealing with small businesses versus clients with an HR and Purchasing department but your Roadmap addresses the typical client when web designers first start out. I like it!
