Technical SEO nightmares on client-side react web apps

brightonSEO October 2025

This talk is suitable for people with a couple of years of technical SEO under their belt and a knack for rendering and indexing conundrums.


In this talk, Simone lifts the lid on how JavaScript affects what search engines actually see - starting from the basics of indexation, then diving into a site migration gone sideways due to a dodgy client-side routing configuration in a React app.

It’s one for the technically curious: think rendering quirks, indexing bottlenecks, and sharp lessons from the technical SEO front lines.
