Every report published here is in this comparison, so it is a reference population of pages tested from one server - not a benchmark of the whole web.

What these numbers mean

The first byte arrived in 284 ms. That is workable, and the cheapest win left is caching or a warmer connection.
The page transfers 878.5 KB over 26 request(s). Images files are 83% of it, so resize and recompress the largest images before anything else.
The HTML itself arrives gzip-compressed.
It runs over HTTP/3, so the assets share a connection instead of opening one each.
The largest element painted at 672 ms, inside the 2.5 s Google calls good.
Layout stayed still (CLS 0.005), so nothing jumps under the reader's cursor.
The main thread was blocked for 260 ms, so taps and scrolling wait while scripts run.

Fix first: Image delivery and format - Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.

Read on one shared server, not a visitor's phone: use it to compare pages against each other, not as a promise about every connection. We fix what these tests find.

Top issues

Image delivery and format

high impact

1 image(s) over 200 KB and 0 large image(s) still served as JPEG or PNG.

Fix: Serve WebP or AVIF with a JPEG fallback, size images to the space they occupy, and lazy-load anything below the fold. Images are usually more than half of a slow page.

Render-blocking resources

high impact

10 render-blocking resource(s) in the document head (1 script(s), 9 stylesheet(s)). The page cannot paint until each one arrives.

Fix: Add defer or async to scripts that do not change the first paint, inline the critical CSS, and load the rest with media="print" plus an onload swap.

Avoid extra redirects

medium impact

1 redirect hop(s) before the page load started, each one a full round trip before the first byte.

Fix: Link to the canonical URL (and make sure http, the apex domain and www all point at it) so no visitor pays a redirect first.
