What Are Core Web Vitals?
Customers expect a seamless experience from websites. When a site loads slowly or doesn’t display correctly, users quickly abandon the site.
To measure how well your page is loading for users, Google considers certain performance measurements related to how well your page loads, displays, and unexpectedly changes. There are three Core Web Vitals metrics that contribute to user experience and rankings:
Largest Contentful Paint (LCP)
This measures how long it takes the largest element — usually an image or video — to load on a page. It’s a shorthand measure for how long it takes for the page to be visible to visitors.
Interaction to Next Paint (INP)
This metric measures how long it takes different elements on a page to respond after a user interaction, like a click or hover. INP replaced First Input Delay (FID) as a Google Core Web Vitals metric in 2024.
Cumulative Layout Shift (CLS)
This tracks how many objects shift unexpectedly on your page as users scroll down or additional content loads.
Taken together, these three metrics give a good measurement of how well your page displays to users. Higher individual scores are considered better for your Core Web Vitals SEO.
Why Core Web Vitals Matter for SEO
Google and other search engines reward websites that provide visitors with useful content on a well-functioning website. Since Core Web Vitals measure the real-world experience on your site, they are a critical factor in Google’s ranking system.
Improving SEO Core Web Vitals means achieving and maintaining high Core Web Vitals scores by optimizing the three main performance measures.

Our Core Web Vitals Optimization Process
Just like a car’s tune-up includes diagnostics and incremental improvements, our Core Web Vitals consulting program follows a carefully determined process.
Step 1 — Performance Audit
We analyze your Core Web Vitals metrics using industry-standard diagnostic tools, like Lighthouse and PageSpeed Insights. Using multiple tools allows us to run a deeper, more complex core web services audit that gets to the root of performance problems.
Our team measures server response time using real-world field data gathered from your website and compares it to Google-provided lab data. Synthesizing multiple streams of data lets us accurately interpret discrepancies and provide the most accurate representation of your site’s performance.
Step 2 — Issue Identification
Your Core Web Vitals scores help identify areas where your website may need help under the hood.
Our team pinpoints the issues leading to undesirable scores and locates them specifically within LCP, CLS, or INP. Some sites have problems across metrics, while others simply have issues with one.
Step 3 — Technical Optimization
Once our team has clearly diagnosed the technical problems harming your SEO Core Web Vitals, we will get started on your personalized Core Web Vitals optimization. This is tailored specifically to your audit, so you won’t pay for unnecessary updates.
While we address the particular problems diagnosed in your audit, there are a few that frequently need fixing, including:
- Image compression issues
- Unstable layouts
- Too many HTTP redirects
- Disabled page caching
- Lack of a content delivery network (CDN) to distribute information closer to users
We see these problems all the time, so our team can quickly identify and update these seemingly small issues that have a big impact on your site’s appearance and performance.
Step 4 — Continuous Monitoring
Web development, just like any complex system, benefits from small, trackable, and incremental improvements. Each update is designed to improve your site’s performance and Core Web Vitals scores. Continuous monitoring ensures that we catch future inefficiencies early on — before they slow down your website and cost you customers and sales.
Benefits of Core Web Vitals Optimization
Your website is your most important marketing tool. When it’s running at peak efficiency, your site loads quickly, displays accurately, and provides a positive user experience for all visitors. This improves your overall conversion rates and search engine rankings.
Who Needs Core Web Vitals Optimization?
The biggest culprits in slow, poorly displayed pages are sites with a lot of content. This typically includes e-commerce sites, which have a lot of product photos, and content-heavy sites that include interactive elements like maps or AI-augmented tools. Heavy traffic can also place additional demands on your site, leading to server errors. Basically, any site with low Core Web Vitals scores can benefit from Core Web Vitals optimization services.

What are the three Core Web Vitals metrics?
The three main Google Core Web Vitals are:
LCP: Largest Contentful Paint measures how long the largest element on a page takes to load — usually an image or video.
INP: Interaction to Next Paint measures how long it takes page elements to respond after a user interacts with them. It replaced First Input Delay (FID), which only tracked the user’s first interaction with a page element.
CLS: Cumulative Layout Shift tracks unexpected layout changes on your page; the fewer, the better.
How long does it take to fix Core Web Vitals issues?
It depends on the size of your website and the number of technical issues that need to be fixed. Think of it like a car tune-up — a brand-new sedan will take less time to optimize than a classic sports car that’s been sitting in a garage without maintenance for years.
