Half of All Websites Fail Core Web Vitals — Here’s Why That’s Your Advantage

Here’s a stat that should make you feel optimistic: only 48% of mobile pages pass all three Core Web Vitals metrics.

That means more than half your competitors are handing you an advantage by having slow, janky websites. And they might not even know it.

A quick refresher on Core Web Vitals.

Google uses three metrics to measure page experience:

• Largest Contentful Paint (LCP): How fast does the main content load? Target: under 2.5 seconds.
• Interaction to Next Paint (INP): How quickly does the page respond when you click or tap something? Target: under 200 milliseconds.
• Cumulative Layout Shift (CLS): Does the page jump around while loading? Target: under 0.1.

INP replaced the old First Input Delay (FID) metric in March 2024. It’s a tougher standard — it measures responsiveness across the entire visit, not just the first interaction. And 43% of sites still fail to meet the 200ms INP threshold.

Speed directly affects clicks and conversions.

The data here is clear:

• A 1-second delay in page load time drops conversions by 7%
• Loading just 0.1 seconds faster increases conversions by 8.4%
• 63% of visitors bounce from pages that take 4 or more seconds to load

These aren’t vanity metrics. Every bounce is a wasted click. And in Google’s NavBoost system, a click followed by a quick bounce looks like a bad result. A click followed by a long, engaged visit looks like a good one.

Speed turns “good clicks” into “bad clicks.”

This is where Core Web Vitals and CTR connect directly. Imagine you’ve optimized your title tags, earned more clicks, and moved from position 6 to position 3. Great. But if your page takes 5 seconds to load on mobile, a significant percentage of those hard-earned clicks will result in immediate bounces.

Google sees that pattern. NavBoost sees users clicking your result and then hitting the back button. That’s not the engagement signal you want to send.

A fast page does the opposite. It rewards the click. The user stays, reads, engages. Google registers a satisfied click. Your CTR gains stick.

52% of the field is failing this test.

That’s the opportunity. If your site passes all three Core Web Vitals thresholds while your competitors’ sites don’t, your pages will:

• Keep visitors instead of bouncing them
• Convert more clicks into actual engagement
• Send stronger positive signals to Google’s ranking systems

You don’t need to be the fastest site on the internet. You just need to be faster than the majority — and right now, the majority is failing.

Page speed is CTR’s silent partner. Earning the click is step one. Making the click count is step two. And right now, more than half the web is dropping the ball on step two.

That’s not a problem for you. That’s an opening.

Please note: there are no guarantees in search engine optimization, ever. There are innumerable factors that can affect search engine rankings. And, realistically, most sites should focus their efforts on traditional SEO before even thinking about using non-traditional techniques like SerpClix. All SEO efforts can involve an element of risk. Some techniques are certainly more risky than others. SerpClix employs real human clickers, so we think our service is far less risky than trying to use automated or robotic click methods. But, like all SEO strategies, there is an element of risk because Google’s algorithm is unknown and subject to change at any time. For more information please see our Buyer FAQs.
