Seeking Advanced Monetization Strategies for a Long-Standing, High-Traffic (50M Clicks/Week) Gaming Site

I'm looking for some high-level advice from the community on how to best monetize a niche website I've been running for the past decade.

First, some quick context. The site is in the gaming niche and has a very stable, long-term traffic profile.

The Numbers:

• Google Search Clicks: ~50 million per week
• Google Search Impressions: ~80 million per week
• Audience: 99% Indian
• Monthly Operating Cost: ~$20

To be clear, these aren't new or fluctuating numbers. The site has performed at this level consistently for years, and the analytics are solid. I'm not here to question the traffic; I'm here because I'm certain I'm not maximizing its revenue potential.

My questions for the community are purely about monetization strategy:

1. Beyond AdSense, What's Next? For a site with this volume, what ad networks or ad management partners are best equipped to handle massive Indian traffic in the gaming niche? Who should I be talking to for premium CPMs/CPCs?
2. What's a Realistic Revenue Target? For those experienced with the Indian market, what kind of Revenue Per Mille (RPM) is achievable with this kind of niche traffic? I'm trying to set a realistic financial goal.
3. Untapped Revenue Streams? Beyond display ads, what are some powerful monetization models I should be exploring? I'm thinking about:
   • Affiliate Marketing: Are there specific Indian gaming or e-commerce affiliate programs that would convert well with this audience?
   • Direct Deals: How would you approach selling ad space directly to gaming companies, app developers, or other brands targeting the Indian market?
   • Lead Gen/PPL: Is there potential for pay-per-lead models related to gaming or draws in India?

I've been maintaining this site on a very low budget for a long time, and it's clear I'm sitting on a significant asset. I'm looking for actionable advice to help me build a serious monetization engine on top of the traffic foundation I have.

Thanks for sharing your expertise
