Kyupol and wolflu66 are right.
Post in Promotions but don't be obnoxious. If it says novel, and you have a comic, don't post and vice versa.

be patient. It honestly takes time. I uploaded every day for over a month and only just hit 100, likely because I could upload everyday and stay in the "just updated" category. If you can't, realize it may take longer.
Social media is great, but again, its good to connect with other creators. Boost their work to your followers and they'll usually do the same. Art trades are also great as it helps show that you, again, are engaging
