What is Page Speed? Why Does It Matter?
Page speed is the time it takes for a webpage to fully load when someone visits it. A fast-loading website improves user experience, reduces bounce rates, and ranks better on search engines like Google. In simple terms, if your site loads quickly, visitors are more likely to stay, browse, and even make a purchase.
Imagine clicking on a website and waiting too long for the content to appear it’s frustrating, right? That’s why businesses and website owners focus on improving page speed. A slow website can drive users away, while a fast one keeps them engaged.
Key Components of Page Speed
Several factors affect how quickly a webpage loads. Here are the most important ones:
-
Largest Contentful Paint (LCP): This measures how long it takes for the biggest visible content (like an image, heading, or video) to load. A good LCP score is under 2.5 seconds. Faster LCP means users see important content quickly.
-
First Input Delay (FID): This checks how fast a webpage responds when a user clicks a button or link. Ideally, it should be under 100 milliseconds. A quick response time makes the website feel smooth and interactive.
-
Cumulative Layout Shift (CLS): Have you ever clicked on something, but the page suddenly shifts, making you tap the wrong button? That’s bad, CLS. A stable page layout prevents these annoying shifts, improving usability.
-
Time to First Byte (TTFB): This measures how quickly the server starts sending data to the browser. A lower TTFB means the page begins loading faster, improving overall speed.
-
Total Blocking Time (TBT): This tracks how long a page remains unresponsive due to background scripts running. Optimizing JavaScript helps reduce TBT, making the site more responsive.
-
Render Time: This refers to how fast the browser displays content on the screen. The quicker this happens, the smoother the browsing experience.
