Organizer Recap Tech SEO Summit 2025

Several weeks before our 2nd Tech SEO Summit in April we sold out the tickets. Wow. We’re still overwhelmed with all the positive vibes and feedback. Seems our vision of a nerdy technical SEO conference hits the right spot. 97% of attendees want to attend the summit in 2026 if time/budget allows for it. To name just a few attendee voices from our feedback survey:

“Finally, I can say that a conference was worth it!”

“You put together a hell of an event.”

“Best conference for SEO nerds!”

“Well worth the money and time. The depth and quality of the talks are on another level.”

“This conference made me forget all the others. The true tech focus makes it the best conference for me.”

Besides the more in-depth 45min technical SEO talks, while skipping the basics, I really like that our networking concept works out so well to connect like-minded SEOs. The nerdy conversations during the breaks and at the evening event are a joy to listen to. In addition, because of the nerdy audience, rather shy techies seem to connect more easily with other participants as well, which is awesome!

The real highlights are of course our speakers. This year’s talks were:

Conceptual models, video games, and Google exploits

Mark Williams-Cook expanded on the Google exploit they found, talked about topical authority, SERP composition, twiddlers, site quality score and much more. All neatly packaged with some Monkey Island and gaming memories.

JavaScript Performance Optimization Primer

Martin Splitt did a deep dive into performance optimization for JavaScript. While using the chrome devtools to showcase some performance killers, he even dropped out of his presentation and did some spontaneous “yolo” live coding on screen to explain details.

How to run SEO A/B testing for large websites

Gus Pelogia tried to answer the question “How do we know this is happening because of the things you did?” while using Causal Impact and explaining his approach to A/B testing. He shared some practical examples and learnings based on own tests.

Workflow automation for the productively lazy

Roxana Stingu confessed her main drive to automation is not wanting to do the same task again and again. She shared many examples from her automation flows and what triggers can be used to organize a multi-step process. She inspired us to reclaim hours of boring work.

What to do if Google doesn’t stop crawling?

Dan Taylor ♒ shared an extensive “fail case” with the audience. Describing in therapeutic detail what caused the issues and how the site tried to stop and remedy it… and failed. Adding details of what initially stalled and obfuscated the technical analysis.

Demystifying Organic Product Grids

Pascal Landau took the audience on his explorative journey into researching undocumented parts of the organic “grid system” for products and how to identify and classify them – using Google’s shopping graph for tracking of product offers.

I also want to thank Rene Dhemant again for agreeing to be the stand-by speaker if some last-minute obstacles would prevent someone else from speaking. Ungrateful gig, but it’s awesome when someone agrees to do it. And especially since he would have nevertheless brought new content with him.

Tech Tip Competition

We closed the conference part again with a competition: Each contender had a few minutes to present a tip, using only a few slides. We heard very different tips covering topics like intent gap analysis, strengthening entities with structured data, finding the perfect image size, up to leveraging chrome URLs for performance and debugging. In the end the audience-applausometer voted for Mark Williams-Cook to take home the trophy for the first place and a free ticket for the next summit.

Note: We heard your feedback about wanting more data about the competition ranking and will do live voting on the big screen next year. Nerds!

Mark shared his winning tip recently in a webinar, if you check the event in the comments, you can still find a recording of it:

Networking Event

After all brains had melted from a long conference day with ample input, we took a short stroll along the Hamburg harbor promenade to the evening venue and enjoyed a relaxed evening with lots of great food and drinks on board the museum ship Rickmer Rickmers, a barque built in 1896.

We asked our attendees for lengthy feedback after the conference and 65% filled out the survey, rating the speakers and providing a lot of input. Thank you for this, also in the name of our speakers. As it’s really valuable to get good feedback, we pass it on in summarized form (anonymized) to all speakers. We got very high praise from many and the overall rating for the conference, whether we have met the expectations of the attendees, was 4.8/5 stars, which is awesome for an advanced conference.

We already decided to organize the Tech SEO Summit in 2026 again, will post the date soon™ and open our speaker pitches again. I also never tire of mentioning that we are big supporters of events compensating their speakers at least somewhat and we pay up to 2.000 EUR, depending on travel distance, as a speaker budget. Other conferences should also do this if the content is new and the speakers have put a lot of effort into it. Fortunately, we are not doing this as a business purpose, Audisto is a technical SEO software company after all, but because we believe a nerdy industry meetup is needed and we’re having fun ourselves.
