Why Website Performance Impacts Everything — From SEO to Sales
Introduction
A slow website doesn’t just annoy your visitors — it hurts your search rankings, conversions, and revenue.
In today’s fast-paced digital world, people expect websites to load in under 3 seconds. If your website responds slowly, most visitors will abandon your site quickly — and Google will notice (Bounce Rate).
Whether you’re running an eCommerce store, a local service business, or a national brand, website performance plays a direct role in your online success. Let’s break down what performance means, why it matters, and how to fix common issues.
What Is Website Performance?
Website performance refers to how quickly your website loads and responds to user actions. Key performance indicators include:
*Page load speed
*Time to first byte (TTFB)*
*Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift)
*Server response time
*Image and script optimization
*Caching and compression
TTFB measures how long it takes for a user’s browser to receive the first byte of data from your server after making an HTTP request.
It’s the time between:
The browser requesting a page, and
The first byte of the response being received from your server.
It’s measured in milliseconds (ms) and is the first indicator of whether your site/server is fast or slow.
Why Website Performance Matters
Google has confirmed that site speed is a ranking factor, especially on mobile. In this way Google penalizes slow websites.
53% of mobile users will abandon a site if it takes longer than 3 seconds to load. Your content or product won’t matter if they never see it.
Every second your site’s response to a User’s action reduces conversions by up to 20%. Fast sites build trust, reduce friction, and make people more likely to buy or engage.
Google’s Page Experience algorithm heavily weighs Core Web Vitals — and performance is the backbone of that.

*Too many plugins or third-party scripts
