A reminder from Music 3.0 blog:
A website many times gets overlooked as an integral piece of your digital promotional life because there are so many other places that you can use as your online focal point. Having a Facebook page or Tumblr blog, or relying on another social network as your online central focus has a number of potential flaws, not the least is control of your message.
When you depend on a social network for your online presence, you’re ceding control to an unknown, unseen force that can change its will at any time with no regard to your online well-being. If you rely on an external network, sooner or later you’re going to get burnt. It’s the nature of the Internet to constantly change, and it’s too early to get a feel for the life span of even of the largest sites and networks.
An artist’s website is the only place online that you can control the look, feel, and information and never have to worry about it changing unless you want it to. Don’t trust your online presence to social networks.
This mirrors the first piece of advice I give every time I start consulting an artist or label. Relying solely on social media (or not having social media posts consistently point to the artist's website) is the most common and harmful mistake out there.
