Frequently Asked Questions

What are Core Web Vitals and why do they matter?
Core Web Vitals are Google's set of standardized performance metrics: LCP (loading speed), FID/INP (interactivity), and CLS (visual stability). They are an official Google ranking signal, meaning poor scores can negatively affect your search rankings.
What is a good page load time?
Google recommends that Largest Contentful Paint (the main content loading) happens within 2.5 seconds. Pages loading under 1 second feel instant; above 3 seconds users start abandoning the page.
What are the most common ways to speed up a web page?
The highest-impact improvements are usually: compressing and serving images in WebP format, enabling browser caching, minifying CSS/JS, using a CDN, reducing server response time (TTFB), and eliminating render-blocking resources.
