Page takes too long to become usable

What this means for your business

Your page takes a long time before menus, buttons, and forms start working. Visitors who click something during this window get no response — which feels like a broken site.

How to fix it
Hard
2–5 hours

  1. 1Time to Interactive is how long until your page actually responds to clicks. A page can look loaded but still be frozen — high TTI is almost always caused by too much JavaScript running at startup.
  2. 2Audit every plugin, app, and third-party tool on your site. Each one adds JavaScript that runs on every page load. Remove anything you don't actively use.
  3. 3Ask your developer to delay code for things visitors haven't interacted with yet — popups, dropdowns, forms halfway down the page. Load those on demand, not upfront.
  4. 4Replace heavy analytics or marketing scripts with lighter alternatives. Some tools are significantly more efficient than others for the same function.
  5. 5Check if you're loading full libraries when you only use a small part — a common example is loading all of Bootstrap or jQuery for just a few features.

On WordPress

WP Rocket's "Delay JavaScript" and "Remove Unused CSS" features directly improve TTI. Enable both in the plugin settings.

On Shopify

Go to Online Store → Themes → View report (the Speed report) — Shopify shows your store's performance score and the top factors dragging it down. This tells you where to focus before making any changes.
