Why Speed Matters for SEO

In the fast-paced digital world, speed is money. Google has explicitly stated that Page Speed is a ranking factor for both desktop and mobile searches. A slow website frustrates users, increases bounce rates, and lowers your conversion rates.

Our Website Speed Test connects directly to Google's Lighthouse API to provide you with the same data Google uses to rank your site. It breaks down complex metrics into a simple score out of 100, helping you identify exactly what is slowing you down.

Key Features

Core Web Vitals

Get a Pass/Fail assessment on the three critical metrics: LCP, INP, and CLS.

Mobile Simulation

Tests your site on a simulated 4G mobile network to show real-world performance.

SEO Audit

Checks for meta tags, accessibility issues, and best practices alongside speed.

Detailed Diagnostics

Identifies large images, unused JavaScript, and render-blocking CSS slowing you down.

How to Analyze Your Website

Optimizing your site starts with a diagnosis. Follow these 3 steps:

1

Enter URL

Paste your full website address (e.g., https://example.com) into the input box.

2

Choose Device

Select 'Mobile' or 'Desktop'. We recommend optimizing for Mobile first as Google does.

3

Analyze

Click the button. In a few seconds, you'll get a score out of 100 and a list of fixes.

Understanding Core Web Vitals

New Metric Alert: In March 2024, Google replaced FID (First Input Delay) with INP (Interaction to Next Paint). Our tool is updated to reflect this change.

1. Largest Contentful Paint (LCP)

This measures Loading Performance. It marks the time when the largest image or text block is fully visible.
Target: 2.5 seconds or less.

2. Interaction to Next Paint (INP)

This measures Responsiveness. It checks how quickly your page responds after a user clicks a button or taps a link.
Target: 200 milliseconds or less.

3. Cumulative Layout Shift (CLS)

This measures Visual Stability. Does your content jump around while loading? (e.g., an ad pops in and pushes text down). A high CLS is frustrating for users.
Target: 0.1 or less.

Frequently Asked Questions

Why is my mobile speed score lower than desktop?
Mobile scores are strictly simulated using a slower 4G connection and a mid-range device CPU (like a Moto G4) to represent real-world conditions. Desktop tests assume a fast fiber connection and powerful processor, making it easier to score 90+.
What is LCP (Largest Contentful Paint)?
LCP measures loading performance. It marks the point when the main content of the page (usually a hero image or H1 heading) has likely loaded. A good LCP score is 2.5 seconds or less.
How does Core Web Vitals affect SEO?
Google uses Core Web Vitals as a direct ranking factor. Sites that pass the assessment (Good LCP, CLS, and INP) may receive a ranking boost over slower competitors, especially in mobile search results.
What is the difference between Lab Data and Field Data?
'Lab Data' is a simulation run right now in a controlled environment (Lighthouse). 'Field Data' (CrUX) comes from real users who have visited your site over the last 28 days via Chrome.
How can I improve my CLS score?
Cumulative Layout Shift (CLS) happens when elements move unexpectedly. To fix it, always set explicit width and height attributes on images and videos, and reserve space for ads so content doesn't jump when they load.
