We have written a short recap of the Tech SEO Summit 2025.
Conceptual models, video games, and Google exploits
An exploration into understanding how Google's algorithms fit together, based on new axioms from a Google exploit which revealed parameters and values used by Google, wrapped in a protocol buffer, in the framework of your favourite video game.

JavaScript Performance Optimization Primer
In this session we will look into a process to identify, hunt down and resolve performance issues stemming from JavaScript. We will explore the performance tab, performance tooling, parallelisation and more. We will also talk about the GPU and rendering performance a bit and see how a bit of CSS can make a big difference in performance.

How to run SEO A/B testing for large websites
Are you tired of saying “it depends” every other day? In this talk, Gus will show you how to run SEO A/B tests that will give more accurate answers to your optimization efforts. Content optimization, title changes, links, structured data and other optimization strategies can be measured using Causal Impact and measure how much a strategy impacted in your KPIs. You'll learn how to come up with a hypothesis, create control/test groups, run and improve tests - and talk about real business impact instead of SEO lingo.

Workflow automation for the productively lazy
What if you could reclaim hours of your day by automating the tasks you do over and over again? This talk dives into the practical and strategic side of workflow automation, showing you how to free up time, simplify repetitive processes, and turn “constructive laziness” into a powerful tool for productivity. You’ll leave with actionable insights to create scalable, efficient workflows that save time and deliver measurable results.

What to do if Google doesn’t stop crawling?
Imagine a website where Google accidentally gains access to two staging environments and starts crawling billions of URLs created by a technical flaw. What happens when Google stumbles into the wrong part of your website and how does this affect Google’s indexing and crawling attitude? In this session, we’ll answer this question by looking at a real example. We break down exactly how this happened, what analyzing log files revealed about Google’s crawl behavior, and the unexpected challenges of trying to undo the damage.

Demystifying Organic Product Grids
Did you know Google uses a “Global Product Cluster ID” for most of the products shown in Organic Product Grids? Or that there is an undocumented Google API hidden in the Chromium source code that provides this ID for a given product URL? These are some of the things we uncovered while deep-diving into the inner workings of Organic Product Grids and we’ll share our findings and our process to get there (cross referencing the leaked Content Warehouse API and the Chromium Code Search).
