I used to have my own site (as part of a requirement for my bfa undergrad) but stopped paying for it after a couple years post-graduation. It didn't really help me at all as I found sites that could do everything I needed presented in a more professional layout, like portfolios and comics.
On the one hand, it's nice to have a page where you can have your entire body of work, and there are no limitations on the content you can post.
But overall it's just not worth the money and effort for me personally.
Speaking as a consumer, I rarely visit artists' personal sites. In the past six months I've only maybe visited 2, just to find their shopfronts to buy merch. Instead I follow people on the sites where there's a community and an amalgamation of multiple creators, like instagram, tapas, artstation, etc.
Heck, even just looking through artist's portfolio, I find I get a broader sense of their work on their instagram than what they present on their personal site (particularly when I was looking at tattoo artists).
