From Zero to Hero: How Core Web Vitals Transformed Our Organic Ranking

Blog

The digital ecosystem is unforgiving. In the pursuit of the perfect user experience, Google has established Core Web Vitals and SEO as fundamental pillars. These metrics aren't just numbers; they're the yardstick by which your website's speed, interactivity, and visual stability are measured, directly influencing how the search engine treats you. If you're wondering how to go from mediocre performance to dominant organic ranking, the answer lies in optimizing these three key metrics.

The challenge for many website managers is similar: how to decide which optimization actions to prioritize to achieve the greatest impact in the shortest amount of time? Sometimes, it's difficult to discern which adjustments will make a difference. Fortunately, the Google team has shared a series of practical recommendations applicable to the vast majority of websites, simplifying this decision-making process. Our goal at Click Online 360 is to help you break down and implement this roadmap so your website becomes a model of speed and usability.

Mastering Largest Contentful Paint (LCP)

Largest Contentful Paint (LCP) is the metric that measures the time it takes to load and render the largest main content element on a page. A fast LCP is synonymous with a perception of instant loading, and it's a battle that, according to Google, only half of websites are winning. To transform your LCP, focus on the following:

  1. Immediate Visibility of the LCP in HTML : In most cases, the main content is an image. For the browser to load it quickly, its URL must be easily accessible from the HTML source code without waiting for heavy CSS or JavaScript files to be downloaded and processed.

  2. Prioritize the LCP Resource: Even if you use a standard <img> tag, the presence of multiple <script> elements in the <head> can delay the loading of the LCP image. It's crucial to avoid actions that lower its priority, such as the loading="lazy" attribute. Beware of image optimization tools that apply lazy loading indiscriminately!

  3. Reduce Time To First Byte (TTFB) with a CDN: TTFB is the time it takes for a browser to receive the first byte of the server's response. To minimize this, it's recommended to use a Content Delivery Network (CDN). A CDN serves your content from geographically close locations to your users and uses caching efficiently, dramatically speeding up your website's initial loading time.

Visual Stability with Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) assesses visual stability, specifically how much content shifts unexpectedly while the page loads. A "bad" CLS is frustrating for users and penalized by Google. Approximately 25% of websites still fail to meet this standard.

  1. Define Specific Dimensions: The main cause of shifts or movement is images, ads, and iframes without a defined size. It's vital to set the width and height attributes, or their CSS equivalents. A modern solution is to use the aspect-ratio property, which allows the browser to automatically calculate the height based on the width.

  2. Ensure Bfcache Eligibility : Browser back-forward caching (bfcache) allows pages to load almost instantly using a snapshot. If your page is bfcache-eligible, you eliminate any possibility of layout changes when navigating backward or forward. Check compatibility with Chrome DevTools.

  3. Avoid Unnecessary Animations: Animating elements can shift content, negatively impacting CLS. Google notes that pages with animations are 15% less likely to have a good CLS. If you must animate, use the CSS transform property to ensure smoother transitions and avoid costly redrafts.

Interactivity and Responsiveness: FID/INP

Responsiveness is critical. First Input Delay (FID) measures how quickly a page responds to a user's first interaction. While many sites have good FID, Google is promoting Interaction to Next Page (INP) as its potential successor, which measures the latency of all interactions. The following recommendations are key to improving both:

  1. Divide and Conquer: Long Tasks: Browser tasks that exceed 50 milliseconds block the main thread and prevent a fast response. The trick is to break these long JavaScript tasks into smaller subtasks. This allows the browser to process interactions and rendering updates more quickly.

  2. Remove Unnecessary JavaScript: Too much unnecessary JavaScript creates a competition for tasks that impacts responsiveness. Use tools like Chrome DevTools to audit and remove code that isn't essential for the initial load process, ensuring your page responds smoothly and quickly.

  3. Intelligent Rendering: The rendering process can be expensive. To make updates lighter, Google recommends: avoiding using `requestAnimationFrame()` for non-visual work, keeping the DOM (Document Object Model) size small, and using the CSS `containment` property to isolate areas of the page and improve rendering performance.
