Často kladené otázky
Základní odpovědi na technické otázky hodnocení a indexace.
What are Core Web Vitals?
Google’s key UX metrics: Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS). They reflect loading, interactivity, and visual stability.
Where do the PageSpeed numbers come from?
Zetawala calls the Google PageSpeed Insights API for the URL and strategy you choose. Scores and opportunities come from that API response.
Does AI change my PageSpeed score?
No. Performance and vitals are from PageSpeed Insights. AI only explains opportunities and suggests beginner-friendly next steps from that data.
Should I prioritize mobile or desktop?
Google uses mobile-first indexing for most sites, so mobile Core Web Vitals are usually the first priority.
Will fixing PageSpeed guarantee higher rankings?
No single fix guarantees rankings. Better speed and CWV often improve UX and engagement, which supports SEO alongside content and authority.
Is this PageSpeed tool free?
Yes. Zetawala’s PageSpeed Insights analyzer is free to run on public URLs (subject to API availability and fair use).
