Core Web Vitals are a set of three main numbers

1. Largest Contentful Paint (LCP)

LCP shows how long it takes for the biggest part of your page, like a hero image or headline, to load. It tells you when people can first see and start using what is on your page.

Ideal Score: Less than 2.5 seconds.
Common issues: Big image files, slow server reply, things that stop pages from loading fast.

Tips to Improve LCP:

Compress and optimize images.
Use a fast hosting provider.
Minimize CSS and JavaScript blocking resources.

2. First Input Delay (FID)

FID shows the time it takes your site to react when someone clicks a link or taps a button. It lets Google know how fast and responsive the site is for people.

Ideal Score: Less than 100 milliseconds.
Common issues: A lot of JavaScript runs at the same time. Some third-party scripts are not set up to work well.

Tips to Improve FID:

Reduce JavaScript execution time.
Break up long tasks into smaller ones.
Load third-party code at the same time, if you can.

Ideal Score: Less than 0.1.
Common issues: Missing image sizes, changing ads, fonts that load late.

Tips to Improve CLS:

Set fixed dimensions for images and videos.
Reserve space for ads or dynamic content.
Use font-display, swap so people can read the text right away while the new font loads.

Quick Fixes to Improve Core Web Vitals

What About Mobile?

Google uses mobile-first indexing. This means your site’s mobile performance is very important for ranking. Many Core Web Vitals problems appear more often on phones than on computers. For example, slow LCP or bigger layout changes. These issues happen because of smaller screens and slower internet speeds.

Test and improve your site for mobile users first. Most people now use their phones to go online.

Common Mistakes to Avoid

Overloading your homepage with large media files.
Using third-party tools (like chat widgets or ads) that make the page take more time to show up.
Not improving images for websites or using old types (like BMP).
Not putting important content at the top, so the page takes longer to load and LCP is slow.

Keep your pages simple. Make them clear and quick to load. If your site has too much stuff, it hurts SEO. It also makes the experience bad for people.

Frequently Asked Questions (FAQs)

Frequently Asked Questions

How often should I check my Core Web Vitals?

It’s ideal to check them at least once a month. Frequent monitoring helps you catch performance drops caused by new plugins, content changes, or updates to your website theme. If you're running a high-traffic site, weekly reviews are even better. Continuous tracking ensures long-term stability and SEO growth.

How do Core Web Vitals affect my overall SEO ranking?

You should expect a structured process that includes onboarding, goal setting, strategy development, regular communication, execution of campaigns, and performance reporting. A good agency will act as a partner collaborating with you to understand your business, crafting a custom plan, and keeping you informed about progress and results.

What types of websites are most affected by Core Web Vitals?

Vanity metrics are data points that look impressive but don’t directly impact your bottom line, such as social media likes, page views, or email open rates. While they can indicate visibility, they’re not strong indicators of business success. What’s more important are actionable metrics like lead quality, conversion rate, and return on investment (ROI). Looking for more details? Contact us today before your competitors do.

Can Core Web Vitals impact conversion rates?

High traffic without conversions often points to deeper issues such as: Poor targeting (the wrong audience is visiting), weak calls-to-action or unclear messaging, website usability issues or slow load times, lack of trust signals (like reviews or security).

Your marketing should not just drive visits; it should drive the right visitors and guide them to act.

Can a slow server impact my Core Web Vitals score?

You’ll know it’s working when you see measurable progress toward your business goals, more qualified leads, better engagement, increased sales, or stronger ROI. Regular reports, clear KPIs, and consistent communication from your agency are key to evaluating success.

Do Core Web Vitals replace other SEO ranking factors?

Organic marketing (like SEO, blogging, and social media engagement) often takes 3 to 6 months to start showing results and may take 6–12 months for significant impact. It builds trust and authority over time, and while slower than paid marketing, it often yields more sustainable growth.

What should I prioritize first when improving Core Web Vitals?

A good marketing report should cover: Key performance indicators (KPIs) tied to your goals, traffic and conversion data, campaign performance summaries, ROI or cost-per-lead/acquisition, insights and recommendations for improvement, clear next steps or action items.
It should be easy to understand, jargon-free, and focus on outcomes. Learn more—how we drive revenue?
