Speed & delivery

What makes the page slow, and what the loading experience measures.

✕ 4! 2i 1✓ 646% · needs work

Rendered page

The page as it rendered on a mobile viewport during the performance test — **Mobile**, measured

The page as it rendered on a desktop viewport — **Desktop**, measured

LCP Poor

6.23s

Largest Contentful Paint

Target ≤ 2.5s

What this measures

How long until the largest thing on screen, usually the hero image, video or headline block, has finished rendering. It is a proxy for "when did this page feel loaded".

What moves it: Serve the hero image in a modern format at the size it is displayed, preload it, and remove render-blocking CSS and JavaScript ahead of it. A slow server response delays it too, so check TTFB first.

INP Needs work

403ms

Interaction to Next Paint

Target ≤ 200ms

What this measures

How long the page takes to respond visibly after a tap, click or key press, measured across every interaction, not just the first. High INP is what makes a page feel unresponsive even once it looks ready.

What moves it: Break up long JavaScript tasks so the main thread is free to respond, defer work that is not needed for the interaction, and avoid large re-renders on every event.

CLS Needs work

0.118

Cumulative Layout Shift

Target ≤ 0.1

What this measures

How much visible content jumps around while the page loads. This is what makes someone tap the wrong thing because a banner or image pushed the layout down underneath their finger.

What moves it: Give images and video explicit width and height so the browser reserves the space, reserve room for ads and embeds, and avoid inserting content above what is already on screen.

FCP Poor

3.35s

First Contentful Paint

Target ≤ 1.8s

What this measures

How long until anything at all appears, the first text or image painted. It separates "the page starts slowly" from "the biggest element is slow": a fast FCP with a slow LCP points at the hero, while both slow points at the server.

What moves it: Cut render-blocking CSS and JavaScript in the head, inline the styles needed for the first screen, and improve the server response time.

TTFBNo data

Real-user response time

Needs real-user data from Chrome UX Report

Render-blocking resources 29 found

29 resources in <head> block the first paint, delaying when anything appears on screen.

What to fix first

Ranked by impact against effort, the top of this list buys the most for the least work.

✕ Critical Largest Contentful Paint is 6.2s (lab data), above the 2.5s target and in the poor range.

Optimise the hero image, remove render-blocking CSS and JS, and improve server response time.

moderate

✕ Critical 1 image has no alt attribute, so screen readers announce nothing and engines cannot read them.

<img src="…" alt="What the image shows">, use alt="" only for decorative images.

quick fix

! Recommended 9 images have no width and height, so the page shifts as they load (hurting CLS).

<img src="…" width="800" height="600">, the browser reserves the space before decoding.

quick fix

! Recommended 29 resources in <head> block the first paint, delaying when anything appears on screen.

Add defer to scripts, inline critical CSS, and load the rest asynchronously.

moderate

! Recommended 9 third-party services account for 67% of what this page downloads, 1.1 MB and 732ms of main-thread time.

Audit what each service earns its weight doing, remove any that duplicate another, and load the rest after the page is interactive.

moderate

! Recommended 30 images below the fold load eagerly, competing for bandwidth with the visible page.

Add loading="lazy" to images below the first screen.

quick fix

! Recommended 24 links have no anchor text, so its purpose is unreadable without sight of the layout.

Add link text, or an aria-label where the link is an icon.

quick fix

! Recommended No Strict-Transport-Security header, so a first visit over HTTP can be intercepted before the redirect.

Strict-Transport-Security: max-age=31536000; includeSubDomains

quick fix

! Recommended Nothing prevents this page being embedded in a frame, which allows clickjacking.

Content-Security-Policy: frame-ancestors 'self'

quick fix

! Recommended Cumulative Layout Shift is 0.118 (lab data), above the 0.1 target.

Set width and height on images, reserve space for ads and embeds, and preload webfonts.

quick fix

! Recommended No heading is followed by a concise 40 to 60 word answer, the shape featured snippets and AI overviews extract.

Open at least one section with a direct 40 to 60 word answer to the question its heading poses.

moderate

! Recommended "und" makes up 4.7% of the page text, which reads as unnatural repetition rather than writing.

Rewrite so the term appears where it reads naturally. Search engines match meaning, not repetition.
