How do you test your website after launch?

Overview

I’ve been thinking a lot about what “post‑launch testing” means in 2025.

We all check the usual stuff — Lighthouse scores, mobile responsiveness, SEO, performance.

But now we’ve also got AI agents crawling, parsing, and even trying to use our sites.

The evolving landscape of post‑launch testing

AI‑driven traffic is becoming a significant part of how users interact with websites.
Beyond traditional metrics, we need to consider how well an AI can understand and navigate our UI.

Tool spotlight: AgentRank.it

I just tried a new tool called AgentRank.it that lets a Vision AI agent navigate your UI and report where it gets stuck.
Pretty interesting idea, especially as AI‑driven traffic grows.

Key questions to consider

• What do you test once your site is live?
• Do you check for accessibility, UX flows, automated browsing, AI‑readability, or something else entirely?
