"guaranteed rate (cpm? cpc?)"

It was guaranteed revenue IIUC, something like "If you do not make at least $150M from this deal, Google will pay you the difference." That makes the deal a no-brainer for AOL, but puts Google on the hook for any shortfall, which could have potentially ended up bankrupting the company.

I couldn't find a great description of the deal terms. I did find mention that at least some of the guarantee needed to be paid up front. I suspect the guaranteed payment was contingent on some level of traffic though -- if AOL had turned off the placement, or lost a huge amount of users, then they probably couldn't keep the money.

Cost per mille or cost for 1000 clicks -its an old-school advertising term

CPM = Cost per mill (cost per 1000 views)

CPC = Cost per Click (cost per 1 click)

These terms are widely used today.
