Built a Simple Core Web Vitals Tool After Getting Frustrated with Slow Audits

A few months ago, I was helping a client improve their site's performance and realized I was spending more time jumping between tools than actually fixing problems.

Most reports would tell me a score, but not clearly explain why the page was slow or which issue would have the biggest impact.

That frustration led me to start using a workflow focused on Core Web Vitals, waterfall analysis, and render-blocking resources in one place. It helped me spot things like oversized images, third-party scripts, and font-loading issues much faster.

One thing I've learned is that improving performance usually isn't about one big fix. It's often a collection of small improvements that add up over time.

For anyone building websites or SaaS products, how much attention do you pay to Core Web Vitals? Have you seen a noticeable impact on rankings, conversions, or user engagement after improving them?
