In this talk, @hellemans.me will provide examples and a framework for analysing SERPs and understanding how to make a positive business impact with your SEO strategies. SERPs are more personalised than ever, and every results page is full of insights that most people aren’t paying attention to.

It includes a black-and-white portrait of Arnout smiling next to large red graphic elements with his name. Below his picture, a black section displays the talk title: "The SERPs hold more insights than you think." A blue footer at the bottom reads: "24 Sep, 2026 | Maddermarket Theatre, Norwich."

A couple of people DMd me about my eye in the Buzzstream podcast. In answer to your question, this was 2 days before recording. 😂 Happy Friday, have a laugh at my expense (excellent shot, almost ended that contest) 🥊

Since 5.4, ChatGPT query fan outs are doing specific site: searches. It is vital information to find out where you need to be to be. I spoke about this with Vince Nero a few months ago on the BuzzStream podcast. You can use QueryFan.com to find these at scale 😎
