Reminds me of the whale oil business being replaced by petroleum. Except the ad-based economy was effectively a google monopsony. I'm surprised the OP managed to make ad revenue for a decade, but to me at always seemed about casino-ish and snake-oily. A decade is impressive but I think we all knew where this was going. I think the question is: will another monopsony for ads arise or will it be content based only? It seems YouTUbe is poised to be the next google since more people watch YouTube than cable, so the audience is captive since there's no alternative (yes I realize Google owns YouTube). But that's still a parasitic economy sucking from google. "Where to go now?" depends on if another ad server can gain dominance, otherwise the answer is "nowhere".
