Hello there Michael Davis!
Regardless whether you have integrated your Google Adsense account in your Hubpages Account or not, there will still be ads in your Hubs.
This is because your hubs are practically operating under Hubpages (which is Adsense integrated as a whole). What does it mean to us, hubbers?
Well, it's simple. Hubpages will get all the revenues from Google Adsense 100% of the time, instead of the 40% (and 60% will be yours) when you have your adsense integrated.
I hope this helps. :)
