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 do you test your website score?
To test your Google Web Core vitals, you can use tools like
These tools set an environment for your website and run something like a Michelin test for a restaurant.
What are web core vitals?
Web Core Vitals are performance metrics introduced by Google to measure how your website feels to real users. They focus on three key areas:
- LCP (Largest Contentful Paint): Measures loading speed. It should be under 2.5 seconds.
- INP (Interaction to Next Paint): Measures responsiveness. It should be under 200 ms.
- 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-web core 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.
Why Page Speed Matters for 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.
- Poor mobile experience: Most users visit on mobile — slow speed here = bad UX.

You can see many case studies of companies that have improved their revenue.

The fix
You should have a performance score of over 90 to rank on Google.
Some of the most effective improvements include
1. Compress Large Images
- Images are primarily the main reason for making the site slow
- Fix: The website should use modern image formats like Webp or AVIF
2. Reduce Unused CSS and JavaScript
- Unused resources will cost you load time and block rendering.
- Fix: Use tools like PurgeCSS, UnCSS, or the built-in audit from Lighthouse to find and remove dead code.
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. Optimize for Mobile First
- Over 60% of traffic comes from mobile. Google also prioritizes mobile-first indexing.
- Fix: Use responsive design, avoid heavy animations, and test mobile layout with Google’s Mobile-Friendly Test.
