Engage and communicate more in the forums and the main web. Make friends, subbing to their story, and the like.
Talk and banter with other creators in the forums and supports their series with liking and commenting on their stories to get noticed, and if they would like to clicked on your profile, you might get a few more subs if it pique their interest. But one thing you need to consider is:
DON'T ADVERTISE YOUR STORY ON THEIR SERIES AND PROFILE COMMENTS PAGE.
It will come out as annoying and obnoxious to everyone since they use it as a way to engage with their reader and want you to comments about their story, not advertising 'your' story.
Also, in the forums, you can promote your series by making a new thread, or putting the links and description on the exiting thread (just search novel). There's quite s lot of novel only thread where you can post it, but don't over do it.
Ask for guidance and their opinions of your series, and you're expected to be able to take criticism when you're the one asking for it.
And I will say that this worked with both comic and novel.
You're new and still unknown, not to mention that the novel section is also a new addition I'm the tapas web, so take it easy.
I can't say that this is a 'pro' tips as I don't even have any daily reader (lol), but its something I know by engaging with the community, and the community is really nice, and who knows, it might worked.
