Performance at a Glance
Lightweight by Design
Made With Intent loads a lightweight snippet onto your website.
By default, the script loads asynchronously, meaning it does not block page rendering or impact core user experience.
The core Made With Intent script is approximately 18KB, gzip compressed, and cached in the browser for 30 minutes by default — keeping network overhead minimal.
Efficient Campaign Delivery
When you create campaigns in the Intent platform, they are bundled into a single campaign script (the “xp” script).
The size of this script scales with the number of active campaigns.
Archived campaigns are automatically excluded from the bundle.
This keeps the campaign layer efficient and fully optimised for performance.
Fast Response Times
The script and associated tracking requests typically complete in under 100ms, ensuring experiences respond quickly to real-time intent signals without degrading site performance.
No Render Blocking. No Forced Flicker Fixes.
Unlike traditional A/B testing platforms that often recommend render-blocking to prevent flicker, Made With Intent is built around real-time intent signals, not page-hiding hacks.
We are exponents of:
Reserving content blocks to prevent layout shift
Loading dynamic campaigns with graceful in-page transitions
Using lightweight animation within an appropriate stacking context using our site templates
Utilising our client-side SDKs in your theme and components to dynamically render content on the fly
This approach avoids blocking the page, prevents disruptive flashes of content, and maintains performance best practices.
Core Web vitals
In our lab testing, we found that there is no measurable impact on Core Web Vitals.
To verify these claims we ran controlled performance tests: the same page measured with the script on and off, across the two conditions that matter most for real-world traffic - a throttled mobile connection and a typical desktop broadband connection.
This mirrors the same testing profiles used by tools like Google PageSpeed Insights, so results are easy for any review board to reproduce.
Bottom line: across every Core Web Vital, on every device profile, the difference between script-on and script-off was too small to be considered a real effect.
Device profile | LCP (loading) | INP (responsiveness) | CLS (visual stability) |
Mobile (throttled, Slow 4G) | No material difference | No material difference | No material difference |
Desktop (broadband) | No material difference | No material difference | No material difference |
For context, on both profiles the page scored in Google's "Good" band for all three Core Web Vitals with the script enabled.
