Small websites under one LLC?

I have several small websites that make a little each month. I've just recently formed my first LLC. I want to associate these small websites under this one LLC, but I'm not sure about some legalities.



Do I need to have DBAs(official fictitious names) for each of the sites? Or, are they just brands of my main LLC? My LLC is pretty generic, and I don't mind having it listed on the bottom of each site.



Any help or direction would be appreciated.



Thanks
