On December 15, 2025, I had the incredible opportunity to join Emanuel Petrescu, founder of How About Some Marketing?, for a live, hands-on webinar: Using Custom GPTs to Create AI Agents for SEO & Marketing.” This session wasn’t just another AI webinar—it was a deep dive into the practical side of building powerful, no-code GPT agents that supercharge SEO, content creation, and marketing workflows.

If you missed the live session, here’s a behind-the-scenes look at what we covered—and why this topic is so essential for modern marketers and creators.

Here’s the presentation:


Why This Webinar Matters: The New Era of AI-Driven SEO

AI is no longer optional for marketers—it’s the core of modern strategy. But the real question isn’t should you use AI—it’s how you apply it in ways that amplify your content without losing your brand identity. That’s what this webinar tackled head-on.

We’re witnessing the rise of Generative Engine Optimization (GEO)—a shift from traditional SEO to optimizing for platforms like ChatGPT, Perplexity, and Gemini. In this new paradigm, marketers need to create content that is not only search-engine friendly but also AI-agent friendly.


What We Covered: Building Custom GPTs That Actually Work

In this session, I walked attendees through how to build custom GPTs trained on their own content, without needing to write a single line of code. Whether you’re a solopreneur or leading a team, this is the fastest way to automate content workflows and scale marketing output with precision and personality.

Key Takeaways:

1. Create GPTs Trained on Your Own Content

I showed how to upload your brand’s existing content and create GPT agents that mirror your tone, values, and style. The result? AI that sounds like you, not a robot.

2. Go From Keyword to Landing Page in Minutes

We built a workflow that goes from keyword research to fully formatted landing pages—complete with metadata, CTAs, and social content—in under 10 minutes.

3. Generate Social Media Content at Scale

I demoed AI agents that write tweets, LinkedIn posts, Instagram captions, and even full blog outlines that stay consistent with your brand voice.

4. Apply the C.L.E.A.R Prompting Framework

To ensure GPTs respond intelligently to messy or vague inputs, we applied my C.L.E.A.R. method for transforming unclear briefings into structured, high-performing prompts.


Live Demos: Watch AI in Action

We didn’t just talk—we built. I demoed several working GPT agents, including:

  • SEO Keyword Research Assistant

  • Social Media Content Generator

  • Assistant for Writing X (Twitter) Posts

  • Full-Service Marketing Assistant GPT

These GPTs are already saving marketers 10–20 hours per week, freeing up time for higher-level strategy and creative direction.


Why This Is a Game-Changer for SEO and AI Content Strategy

My goal in this webinar was to help marketers bridge the gap between theory and practice—especially in a world where visibility is moving beyond Google. Platforms like ChatGPT, Perplexity, and AI-powered search tools are becoming new gatekeepers of discovery.

To succeed, marketers need GEO, not just SEO. They need:

  • Content structured for AI comprehension

  • A strong entity-driven strategy

  • Real-time adaptability with AI-powered systems

Custom GPTs provide this bridge—helping you scale without sacrificing coherence, tone, or quality.
