help Iago FAQ
Does Iago minify JavaScript?
The catalog description says it identifies issues such as unminified JavaScript, large images, and render-blocking resources. Identifying those issues is different from automatically fixing them, and the available record does not confirm automatic minification.
What web metrics would a tool like Iago improve?
Reducing script size, image weight, and blocking resources can improve loading metrics such as First Contentful Paint and Largest Contentful Paint. The actual result depends on the site's code, hosting, device, and network.
What are verifiable alternatives to Iago for website performance checks?
Google Lighthouse, PageSpeed Insights, and WebPageTest are established tools for analyzing web performance. They report measurements such as Core Web Vitals, resource loading, and rendering behavior.
