What was its core prior to advertising? I mean a money-making core.
It wasn't. Every search engine at the time had struggled to make money. It wasn't until Google "borrowed" pay-per-click auction bidding from Overture that advertising became their focus.

But, by that stage, their ad revenue was killing everything.
