I use Deviant Art, Pixiv, Twitter, Instagram, NewGrounds and Tumblr and that's also the order from most interaction to the least. In DA, Pixiv and NewGrounds your tags will decide if people see you at all so do use relevant tags that people actually search for. People don't serach "blackandwhite", "sketch", "study", "fanart", "girl", "man" and other ambigious things. They search for character names, series names, niches, fetish and so on, detailed things. In Pixiv when you adding tags, search for tag and check which one is more popular, the english one or the japanese one and use the more popular one because Pixiv only lets you use 10 tags per work.
Establish clearly what's your main subject and make sure it's something you yourself enjoy drawing and have the know-how of. Let people with the shared interest find and pick you up.
t. having drawn for 4 years, 6k followers in DA, 3k in Pixiv and 1k in Twitter
