Core Web Vitals: A Simple Guide to What Actually Impacts Rankings

I spent months obsessing over Core Web Vitals scores before realizing something important: chasing perfect scores was wasting my time. Let's talk about what actually moves the needle for your rankings.

The Basics You Need to Know

Core Web Vitals sound complicated, but they're really just three ways Google measures user experience:

LCP (Largest Contentful Paint) Think of this as your page's first impression. How long does someone wait to see your main content? Under 2.5 seconds is what you're aiming for. Any longer and you're losing visitors before they even start reading.

FID (First Input Delay) This is all about responsiveness. When someone clicks a button or link on your page, how long do they wait? You want this under 100 milliseconds. Ever clicked something and waited... and waited? That's poor FID in action.

CLS (Cumulative Layout Shift) You know when you're about to click something and the page suddenly jumps? That's what CLS measures. Keep it under 0.1 and your visitors won't be playing whack-a-mole with your content.

The Truth About Rankings

Here's what I've learned about Core Web Vitals and rankings:

Mobile experience matters most. Google cares way more about how your site performs on phones than desktop. Makes sense - that's where most people are browsing.

"Good enough" is actually good enough. You don't need perfect scores. Focus on getting into the "good" range and then move on to other improvements.

Real user experience trumps lab data. Google cares more about how your site performs for real visitors than in testing tools.

Making Real Improvements

Let's keep this practical. Here's where to focus:

Images are usually the biggest culprit:

• Compress them properly

• Use modern formats

• Don't skip setting dimensions

• Lazy load when it makes sense

Your hosting matters:

• Good hosting is worth paying for

• Use caching (it really helps)

• Consider a CDN for global visitors

Keep your layout stable:

• Set sizes for images and ads

• Don't let your header jump around

• Watch out for font loading issues

Focus Your Efforts

Start with:

• Your homepage

• Main landing pages

• Pages that make you money

• High-traffic blog posts

Don't waste time optimizing every single page to perfection. Focus on the pages that matter most to your business.

What's Next?

Core Web Vitals will keep evolving, but the basics stay the same: make your site fast, responsive, and stable. Focus on real user experience, and the rankings will follow.

Remember: Perfect scores look nice in screenshots, but good enough scores with great content will outrank them every time.

Keep it simple, focus on what matters, and don't let perfect be the enemy of good.
