shhhhh
Do you have one of those for each network/niche or one main control panel to control everything?
haha, I don't file this section away as top secret. There are simply just so few people who have the ability to do what I do. I've actually posted about it several times here.
But yes, 1 main domain control panel handles all of my networks. There's no need to duplicate this part IMO, once you've got several million search phrases + volume & cpc for each you're pretty much in all the niches. I just cherry pick the low hanging fruits or search for keywords in the domain to further develop a particular niche.
I forgot to mention the reason I separate networks: Regardless how hard you try, you'll always have some kind of footprint. By separating networks, it allows me to have multiple aff/adsense/epn/... accounts so if one network is breached by a competitor, they'll have a bitch-of-a-time finding everything.
