Website developers are generally not marketing inclined. Sure they can build you a website, but chances are they can't tell you how to use it effectively to get more traffic to your website or leads for your business. For that, you would need someone who is familiar with general marketing concepts, say for example a marketing guy or digital strategist.

The same goes for graphic designers, they can create a new banner for your home page, but can they actually add the banner to your website after creating it? Probably not. For that they would need a website developer or coder. The point is this. It takes more for a brand to become and remain successful, then just a website, or a marketing guy - it takes a team.
