The Fastest Way to Check Your
Core Web Vitals

Run Site Audit

Just enter your domain in the setup and set the
user agent to crawl the mobile or desktop version
of your site.

Review your Core
Web Vitals

Follow the simple recommendations we’ll provide
for each specific score, especially for pages that
are “poor.”

Share the results with
your development team

Share the instructions to optimize each page. After
you’ve implemented changes, re-run Site Audit and
monitor any change to your Core Web Vitals.

Keep historical data to
follow your progress

Semrush always saves your history of CWV scores so
you can track how much you’ve improved.

What Are Core Web Vitals?

There are three Core Web Vitals that Google is encouraging all website owners to
keep track of and improve in order to serve a better user experience.

Largest Contentful Paint (LCP)

Hurt by:

  • Slow server response time
  • Java and CSS that blocks rendering
  • Slow loading resources (especially image and video files)
  • Client side rendering
Check Your LCP
First Input Delay (FID)

We use TBT – a metric recommended by Google as a substitution to FID. It correlates with FID, captures issues that affect interactivity and can be obtained in laboratory conditions. Hurt by:

  • Long tasks
  • Long JavaScript execution time
  • Large JavaScript bundles
  • Render-blocking JavaScript
Check Your FID
Cumulative Layout
Shift (CLS)

Hurt by:

  • Ads causing any change in layout
  • Cookie banners / notices Images without dimensions
  • Dynamically injected content
  • Embeds and iframes without dimensions
  • Web fonts causing FOIT/FOUT
Check Your CLS

We Do The Audit. You Get The Results.
