PageSpeed-style reading
Clear mobile and desktop metrics, with priorities.

Semdash service
We look at what users, crawlers and measurement tools feel: load time, JavaScript cost, CSS weight, TTFB, Core Web Vitals, cache and server configuration.
What we measure
LCP, CLS, INP/TBT logic and user-perceived loading experience.
TTFB, cache, compression, HTTP/2, TLS, DNS and hosting response.
JavaScript cost, CSS weight, render-blocking resources and critical path.
We can optimize templates, assets, server settings and deployment workflow.
Deliverables
Clear mobile and desktop metrics, with priorities.
Cache, compression, images, JS/CSS, server and rendering path.
The goal is to prove gains, not just claim them.
