What needs attention

2 issues High impact

What is slow

The largest visible element appears to be text.

The largest delay is in Element render delay (2,294ms).

Likely cause

The text was available, but the browser waited before painting it. A web font, render-blocking CSS, JavaScript or an entrance animation is a likely cause.

Best first fix

Check the element’s font, CSS and visibility behaviour first.

  1. 1 Check whether the element uses a web font that loads late.
  2. 2 Preload the critical font and use font-display: swap.
  3. 3 Remove entrance animations or JavaScript-controlled reveals above the fold.
  4. 4 Reduce render-blocking CSS and defer non-critical JavaScript.
