What is a countdown timer embed

A countdown timer embed is a small widget that renders a real-time clock counting down to a deadline. You paste the snippet into your page where you want the clock to appear. The script loads asynchronously, reads your settings, and draws a responsive timer that updates in the browser.

Why teams use it:

• Clear deadline that nudges action

• Zero engineering dependency after initial paste

• Works with any modern CMS

• Lightweight and mobile friendly

Copy and paste setup

1. Generate your code with the tool above.

2. Copy the snippet.

3. Paste it where the clock should appear.

   • WordPress - use a Custom HTML block

   • Webflow - add an Embed component

   • Shopify - use a Custom Liquid section or an HTML block in your page builder

   • Squarespace, Framer, Wix - use their HTML or Embed block

4. Publish your page and validate that the clock is visible.

Tips:

• Keep the script async to avoid blocking rendering. See MDN on script loading attributes.

• If your site uses a strict Content Security Policy, allowlist your CDN domain.

• Use one embed per page section to avoid duplicate IDs.

Customization options

• Deadline and timezone - fixed UTC or auto detect

• Layout - inline, stacked, or flip clock

• Units - toggle days, hours, minutes, seconds

• Labels and localization - customize language strings

• Typography - font family, size, spacing

• Colors - brand hex values, light or dark theme

• Alignment - left, center, right

• Behavior at zero - hide, restart on an interval, or show custom text and a CTA

• Accessibility - ARIA roles and readable labels for screen readers

Best practices for higher conversions

• Place the timer above the fold with a single primary CTA

• State the exact end date and time near the timer to prevent confusion

• Pair the clock with proof and clarity - price, benefit, and next step

• Match contrast ratios for legibility on mobile. Use the WebAIM contrast checker

• Keep the script small and async to protect Core Web Vitals. Test with PageSpeed Insights
