Why Website Performance Matters More Than Ever

User experience isn’t just a nice-to-have—it’s a core factor influencing your site’s search engine performance, bounce rate, and conversions. To stay ahead of the competition, website owners and developers must prioritize website speed optimization and understand the importance of core web vitals SEO.

At Decisive Design, we believe that optimizing these elements is not just a technical requirement—it’s a strategic advantage for brands looking to grow online.

A Quick Breakdown: What Are Core Web Vitals?

Core Web Vitals include three specific metrics used to evaluate your website’s performance:

First Input Delay (FID): Evaluates interactivity. Target: less than 100 milliseconds.
Cumulative Layout Shift (CLS): Tracks visual stability during loading. Target: below 0.1.

Improving these metrics is essential for both SEO and user experience, and is a critical component of any core web vitals SEO strategy.
