Scripts are snippets of code that extend your store’s functionality and tracking capabilities. They let you connect third-party tools, run custom interactions, and measure performance across your funnel.

​
Why ecommerce stores need scripts

Scripts power essential parts of your marketing stack. Without them, you can’t track conversions, optimize campaigns, or create personalized experiences. Tracking and measurement — Scripts from analytics platforms and ad networks (Meta Pixel, Google Analytics, TikTok Pixel) capture visitor behavior, clicks, and purchases. This data feeds into your CAC, CVR, and ROAS calculations so you can see what’s working. Interactive experiences — Page-level scripts enable quizzes, personalization apps, exit-intent pop-ups, and cart abandonment flows. These tools improve conversion rates by creating more engaging, tailored experiences for visitors. Integration with marketing tools — Scripts connect your store to email platforms (Klaviyo), SMS tools (Postscript, Attentive), and other services that power your customer acquisition and retention workflows.

​
When to use site-wide vs. page-level scripts

Use site-wide scripts for tools that need to track activity across your entire store.Best for:
  • Analytics and tracking pixels (Meta Pixel, Google Analytics, TikTok Pixel)
  • Performance measurement (CTR, CVR, conversion tracking)
  • Tools that should fire on every page visit
  • Universal integrations (payment processors, shipping calculators)

FAQ

Typically, no. Most scripts should only be added once. Adding a script in both places usually results in duplicate tracking, which skews your data. In addition, adding unnecessary scripts globally slows down your shop. Choose site-wide if you need it everywhere, or page-level if it’s page-specific.
Yes. After adding scripts—whether site-wide or page-level—you need to republish your pages for the changes to go live. Site-wide scripts apply to all pages on your next publish; page-level scripts only apply to the specific page you updated.
Most tracking scripts have browser extensions or test tools (Meta Pixel Helper, Google Tag Assistant) that verify scripts are firing correctly. Check your analytics dashboard or ad platform to confirm events are being tracked. For page-level scripts, test the functionality directly on your published page.
