Why should you fix core web vitals?
Imagine this: someone clicks your website link, a white screen appears, and then they leave the page before it even loads.
A 1-second delay in page load can reduce conversions by 7%.
20% if there is a 2-second delay.
If it’s more than 3 seconds, Ah! You just lost a potential customer.
If your website is slow, it’s silently declining your business growth daily, and most business owners don’t even know it.
Your site performance score should be over 9 to increase your business revenue. A higher score means a faster site. A lower score? That’s a red flag.
How to test core web vitals?
Tools to measure Core Web Vitals:
These tools set an environment for your website and run something like a Michelin test for a restaurant.
What are core web vitals?
Core web vitals are performance metrics introduced by Google to measure how your website feels to real users. They focus on three key areas: LCP, INP & CLS.
What is LCP in core web vitals?
LCP (Largest Contentful Paint) measures loading speed.
It should be under 2.5 seconds.
What is INP in core web vitals?
INP (Interaction to Next Paint) measures responsiveness.
It should be under 200 ms.
What is CLS in core web vitals?
CLS (Cumulative Layout Shift) measures visual stability.
It should be less than 0.1.
These scores impact your Google ranking and user experience. A low Web Core Vital score means slower pages, frustrated visitors, and lost conversions.
What are non-core web vitals?
These aren’t part of Google’s “Core” trio, but they still influence performance and user experience:
- TTFB (Time to First Byte): Shows the time it takes for the browser to get the first response from the server. Lower is better.
- FCP (First Contentful Paint): Time until the first piece of content appears on the screen.
- SI (Speed Index): How quickly content is visually displayed.
- TBT (Total Blocking Time): Time when a page is unresponsive due to heavy scripts.
While not “Core,” these metrics often affect Core Vitals and help identify deeper performance bottlenecks.
These metrics impact your site performance.
Core web vitals SEO impact
Does core web vitals affect SEO?
A slow website doesn’t just annoy your visitors. It hurts your Google search, too.
Here’s how page speed affects your technical SEO:
- Lower rankings: Google pushes faster sites higher in search results.
- Higher bounce rates: People leave if your site takes too long to load.
- Reduced crawl budget: Google crawls fewer pages on a slow site, which means some pages may not even get indexed.
- Not mobile optimized: Most users visit on mobile. Slow speed here = bad UX.

2. Reduce Unused CSS and JavaScript

3. Enable Browser Caching
- It stores parts of your site in the user’s browser so they don’t reload everything on repeat visits.
- Fix: Set cache headers via your server or use plugins.
4. Host on Fast, Reliable Servers
- Server response time affects TTFB and overall speed.
- Fix: You can choose a well-optimized hosting provider like DigitalOcean or AWS.
5. Use a CDN (Content Delivery Network)
- CDNs serve your content from servers close to your visitors for faster loading.
- Fix: Services like Cloudflare, BunnyCDN, or Amazon CloudFront improve load speed and security.
6. Mobile Performance Optimization

- Fix: Use responsive design, avoid heavy animations, and test mobile layout with Google’s Mobile-Friendly Test.
