Definitely need to get your sites a secure cert, I'm not even sure if google will be adding non-secure pages from this point on. Same goes for responsive, if your new sites are like
Porn Nerd Network - Exclusive Network Of Adult Websites then your not going to be listed for mobile surfers, and you will be penalized even for desktop surfers.
Best advice is to get GA loaded for stats, and get profiles setup in webmaster tools so you can see what is going on behind the scenes with google
You should also link from your current sites that are crawled by google, and the spider will find you that way
Good Luck
