Near 40% CTR, but low traffic, how to improve it?

Hi guys,
I’ve signed up with http://www.namedrive.com, it’s a domain parking service.
I’ve added a 41 domain portfolio, I’ve chosen namedrive by recommendation and because it allows me to add my adult domain portfolio as well. I have 18 adult domains.
I’m having great CTR on the adult domains:
views: 197
clicks: 76
CTR: % 38.58
However, this is very low traffic for 18 domains in 2 weeks. Do you think this CTR will mantain good if I get some untargeted traffic (even if it drops a little) ? I think these landing pages are effective but i need more traffic, to get more revenue. But im uncertain how to get traffic to parking domains
thanks in advance
