Everyone is vying for that elusive first-place organic result on Google because ranking in the top position earns you a 39.8% click-through rate. 75% of users don’t even view second-page results!

So, what can you do to lift your organic results?

One of the key tactics in boosting your organic results is improving your website for an optimal Core Web Vitals score. Understanding and optimising for Core Web Vitals are essential for securing higher search rankings, enhancing user experience, and ultimately attracting and converting traffic.

What are Core Web Vitals?


LCP = Largest Content Paint

Measures the time it takes for the largest content element of a webpage to become visible. This metric is important because it indicates how quickly a visitor sees that the URL is actually loading.


FID = First Input Delay

Gauges the responsiveness of a webpage by measuring the time between a user's first interaction and the browser's response. This is important on pages where the user needs to take action because it measures the time it takes to respond.


    CLS = Cumulative Layout Shift

    Quantifies the visual stability of a webpage by measuring unexpected layout shifts during page loading. This is important because having page elements shift while a user is trying to interact with it is considered a bad user experience.
