About Viral content source

Hi
I'm starting a new Viral site + Adsense
I'm running a facebook ads campaign to get like to my page and until now i have more than 2k likes so i'm on the right way.

I know that to get my page more active i can use funny videos, funny pics, etc..
But my question is about articles that i will poste on the website. Basically, those articles must be more attractives to get viral.

I see that many Viral sites like ViralNova, BoredPanda, BuzzFeed, poste at less 5 or 6 viral articles everyday….
