Why Our Cookie Banner is Blazing Fast (And Yours Isn't)

Discover the tech behind our sub-100ms cookie banner. Learn why 'Zero Layout Shift' and a lightweight script are critical for SEO and user experience.

The "Zero Layout Shift" Promise

One of the biggest factors in Google's Core Web Vitals is Cumulative Layout Shift (CLS).

Have you ever visited a site, tried to click a button, and suddenly a cookie banner loads, pushing the content down and making you click an ad? That's layout shift. It's a terrible user experience, and Google hates it.

Most cookie banners are injected after the page starts to load, causing this exact problem.

LoveCookies is built differently. Our script is engineered to load asynchronously and reserve its space before the page renders, guaranteeing zero layout shift.

Speed Is Not a Feature, It's a Requirement

Our script is tiny (under 10kb). This means it loads and executes almost instantly.

  • No Page Bloat: We don't load heavy JavaScript libraries.
  • No Render-Blocking: Our script never blocks your page from loading.
  • Sub-100ms Load: It's loaded and ready before your user even thinks about scrolling.

In a world where a 1-second delay can cost you 7% of conversions, a fast, non-intrusive cookie banner isn't just nice to have—it's a competitive advantage.
