Measured on the connection that fetched the HTML. Every other request on the page waits for the end of this bar before it can start.

Score history

2 tests of this URL, oldest to newest: 94 → 94 out of 100. The top line is a perfect score.

What these numbers mean

  • The first byte arrived in 202 ms. That is workable, and the cheapest win left is caching or a warmer connection.
  • The page transfers 357.7 KB over 26 request(s). Javascript files are 56% of it, so defer what is not needed for the first screen, and drop tags nobody uses.
  • The HTML itself arrives br-compressed.
  • It runs over HTTP/3, so the assets share a connection instead of opening one each.
  • 56% of the weight comes from other hosts (analytics, fonts, embeds), which also means their slow day becomes your slow day.
  • The largest element painted at 372 ms, inside the 2.5 s Google calls good.
  • Layout shift is 0.271 (good is under 0.1): something without a reserved size is loading late - an image, an ad, or a font swap.
  • The main thread was blocked for 225 ms, so taps and scrolling wait while scripts run.

Fix first: Compress text responses - Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.

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.

What the page is made of

Javascript 1 request

Transfer size, compressed as sent. 26 request(s) in total, 357.7 KB across all of them.

Top issues

Compress text responses

high impact

1 text response(s) of 10 KB or more are sent uncompressed, and the document itself is not compressed. That is 201.2 KB of compressible text.

Fix: Turn on brotli (preferred) or gzip for text/css, javascript and text/html in the web server. This is the cheapest win available on almost any site.

Render-blocking resources

high impact

4 render-blocking resource(s) in the document head (0 script(s), 4 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.

JavaScript weight

medium impact

1 JavaScript file(s) over 200 KB: adsbygoogle.js (201.2 KB)

Fix: Split routes, remove unused dependencies, and prefer a two-file build (one pinned library, one application bundle) over many small ones.

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.

Each bar is one request's own response time, scaled to the slowest. Assets were fetched in parallel, so the bars overlap in real time rather than stacking. first party third party
