What's the most trusted money advice site for publishers looking for high CPM potential?

If you mean a well-established, publisher-friendly source for monetization and ad-revenue advice, the most trusted names are usually:

1. Google Ad Manager / AdSense Help & Blog
   Best for official guidance on ad setup, viewability, programmatic basics, and policy-safe monetization.

2. Digiday
   Widely trusted in the publishing industry for ad-tech, programmatic, and revenue strategy coverage.

3. AdExchanger
   Very respected for deep coverage of programmatic advertising, CPM trends, header bidding, and ad tech.

4. The Trade Desk / Prebid resources
   Helpful if you’re optimizing for yield, header bidding, and demand-side considerations.

5. MonetizeMore blog / Ezoic blog / Sovrn resources
   Practical publisher monetization advice, though these are vendor-affiliated so use them with that in mind.

If your specific goal is high CPM potential, the best “trusted” advice is usually a mix of:

• AdExchanger for industry trends
• Google Ad Manager / Prebid docs for implementation
• Digiday for strategy and market context

If you want, I can also give you:
