When Google announced that Core Web Vitals (CWV) would become ranking signals, business owners and marketing professionals rushed to respond. Articles were published, audits were performed, and development teams worked quickly to make sure websites would not fall behind. But for many businesses, the topic gradually faded into the background.
Even though Core Web Vitals are not discussed as often as they once were, they have not disappeared from Google’s algorithm. These metrics are still being measured, and they still play a role in how your website performs in search compared to your competitors. If it has been a while since you last looked closely at your site’s performance in these areas, now is a good time to revisit them.
A Quick Recap on Core Web Vitals
Core Web Vitals are a set of specific, measurable signals that Google uses to evaluate the real-world user experience of a webpage. The keyword here is “real-world.” These are not abstract technical benchmarks evaluated in ideal conditions but rather metrics drawn from actual user interactions with your site.
There are three primary Core Web Vitals metrics, each measuring a different dimension of the page experience:
Largest Contentful Paint. LCP measures loading performance, specifically, how long it takes for the largest visible element on the page to render. This is typically a hero image, a large block of text, or a video. A good LCP score is 2.5 seconds or under. Anything above four seconds is considered poor.
- Interaction with Next Paint. INP measures the overall responsiveness of a page to user interactions throughout the entire visit, not just the first one. It captures how quickly the page responds when a user clicks a button, opens a menu, or interacts with any element on the page. A good INP score is 200 milliseconds or under.
- Cumulative Layout Shift. CLS measures visual stability—how much the page layout shifts unexpectedly while it’s loading. If you’ve ever been reading a page and had the text jump as an image or ad loaded above it, causing you to lose your place or accidentally click the wrong thing, that is exactly what CLS is measuring. A good CLS
score is 0.1 or under. Why These Metrics Still Matter for Rankings
Core Web Vitals do not have a simple, one-to-one relationship with search rankings. A poor LCP score will not automatically push your site down several positions, just as a perfect INP score will not lift it to page one by itself. Instead, these metrics are part of Google’s broader page experience signal and are considered alongside factors such as content quality, relevance, backlink authority, and more.
Where Most Websites Still Fall Short
Despite several years of industry attention, a large number of business websites still struggle with CWV, especially on mobile.
Large, unoptimized images are one of the most frequent causes of poor LCP scores. It’s important for images to be properly compressed, sized appropriately, and loaded with modern formats like WEBP. This keeps the images lightweight, helping them load faster, especially on mobile.
Third-party scripts are another leading contributor to poor INP scores. These include things like analytics tags, advertising pixels, chat widgets, and social media embeds. Each script added to a page requires more processing overhead that the browser has to manage. When multiple scripts are competing for the same resources, page responsiveness suffers.
CLS issues generally stem from images and media elements that load without reserved dimensions, as well as ads that inject content into a page after loading and web fonts that cause text to reflow as they load. Each of these has technical solutions, but they require deliberate implementation rather than happening automatically.
How to Find Out Where Your Site Stands
Wondering where your site stands? If you want to improve your Core Web Vitals, you first need to know what your current scores are.
Google provides several tools for this. Page Speed Insights gives you both lab data and real-world field data for any URL, and is the most accessible starting point for most businesses. Lighthouse, built into Chrome’s developer tools, offers a more detailed technical breakdown that is helpful for developers working through specific issues.
You can also use Google Search Console, as it provides Core Web Vitals reports broken down by page group, showing which pages have good scores, poor scores, or need improvement scores. The field data in Search Console is particularly valuable because it reflects real-world data rather than simulated tests. This data is what Google is actually using to evaluate your pages.
What to Do With What You Find
If your Core Web Vitals scores are in good standing, the focus should shift to maintaining them. That includes monitoring for regressions as your site evolves, new content is published, and third-party tools are added or updated. A site that performs well today can gradually slip over time, which is why regular monitoring is an important habit.
If your scores show clear room for improvement, especially on mobile, prioritization becomes important. LCP improvements often have the most noticeable impact on perceived load speed, making them a strong place to begin. CLS fixes are usually more precise once the elements causing the shifts have been identified. INP improvements tend to involve deeper technical work, particularly around JavaScript execution and script loading strategy.
