Why Google Removed Num=100

E934: Google's quiet removal of the num=100 parameter sent shockwaves through the SEO tooling ecosystem. Many called it an apocalypse. Others barely noticed.

I sit down with Jonathan Berthold, VP of Revenue at Moz, to unpack what actually happened, why Google made the change, and how it connects to a much bigger shift happening across search, AI, and zero-click results.

We cover how SEO is evolving under pressure from AI Overviews, LLMs, and generative search - and why most of the panic is misplaced.

Topics covered: - What the num=100 parameter was and why Google removed it - Whether this change was aimed at SEOs, tool providers, or OpenAI - How rank tracking, impressions, and average position were distorted before the change - Why keyword positions beyond page one rarely matter for real business outcomes - The rise of zero-click search and what it actually means for traffic - How AI Overviews and LLMs are reshaping informational search - Why commercial and transactional queries are far less impacted - The difference between SEO as a strategy vs SEO as a channel - Why brand is becoming the strongest long-term advantage in search - How Moz has adapted its product and analytics approach - What SEO agencies need to change when rankings stop being the primary KPI - Whether AI tools threaten SEO careers - or force better ones - Google vs OpenAI vs other LLMs and what's really at stake - Why "GEO" mostly looks like good SEO done correctly

Key takeaways: - The num=100 removal didn't break SEO - it exposed bad measurement habits - Traffic quality matters more than traffic volume - Informational content still matters, even when clicks decline - Brand visibility now extends beyond Google into AI systems - SEO success is increasingly tied to business outcomes, not rankings

This conversation goes deep into how search is changing without resorting to hype or fear. If you work in SEO, marketing, analytics, or product - and want a grounded view of where things are heading - this episode is for you.
