Tech SEO Summit Talks 2025
Here you find detailed information about the confirmed speakers and topics. All conference topics are hand-picked by Tobias, Sören and Gerd. It’s our nerdy wish list what we deem currently important for Technical SEO and what we want to hear ourselves. We reserve the right to modify the program of the event, including a change of speakers.
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

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.

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).

What language will the talks be in?
All presentations will be in English language. The speakers at this summit come from a diverse international background. Every attendee will be able to speak and understand English.
We value our speakers and their time!
Disclosure: We believe the hard work a speaker puts into a professional presentation should at least be somewhat compensated. We will pay all our speakers between 1.000–2.000 Euro (depending on the distance they have to travel) for travel/accommodation/effort. If a speaker can’t accept or invoice the money due to company policy, we will donate it to a good cause.
Pitch a tech focused session for 2026
