Understanding Google Certified Publishing Partners (GCPP)
Not every ad management company can earn Google’s certification. Being a Google Certified Publishing Partner means the company meets strict standards for trust, transparency, and performance.
For publishers, this certification ensures:
- Better access to premium demand
- Safer monetization practices
- Verified expertise in ad optimization
In short, choosing a GCPP like OKO reduces the risk of scams while ensuring you’re getting the best from Google’s advertising ecosystem.
Overview of OKO
Founded in the UK, OKO has been in the ad monetization space for years, helping publishers improve their ad revenues through advanced optimization strategies. Over time, the company has grown into one of the most respected GCPPs, working with both small blogs and enterprise-level publishers.
By 2025, OKO is seen as a reliable middle ground—offering premium ad tech solutions without making publishers feel locked into restrictive contracts.
Key Features of OKO
1. Access to Google AdX
Unlike AdSense, which is open to all, Google Ad Exchange (AdX) is invitation-only. Through OKO, publishers get access to AdX, which typically offers higher CPMs and premium advertisers.
2. Advanced Header Bidding
OKO uses both client-side and server-side header bidding to increase competition for ad space, ensuring publishers earn more per impression.
3. Real-Time Reporting Dashboard
OKO provides a clean and detailed reporting system, allowing publishers to track earnings, CPMs, and ad performance without delays.
4. Ad Optimization Services
From ad placement testing to layout suggestions, OKO helps maximize revenue while maintaining user experience.
5. Dedicated Account Management
Every publisher gets assigned a real account manager, making it easier to get personalized recommendations.
6. Page Speed & Core Web Vitals Optimization
Slow ads kill user experience. OKO ensures ads are lightweight and fast, helping websites maintain good rankings on Google.
7. Fraud Prevention & Brand Safety
With advanced fraud detection, OKO keeps publishers safe from invalid traffic and risky advertisers.

OKO’s biggest strength is revenue maximization. Here’s how:
- Better fill rates through multiple demand partners

This means publishers aren’t relying solely on AdSense but instead benefit from a multi-network strategy.
