A: Thanks for reaching out

Crezlo Tours are embedded using an iframe, which means they are hosted on our servers, not yours. Because of this:

✅ They do not significantly slow down your website
✅ Most of the heavy assets (images, rendering, scripts) are loaded externally
✅ Your core website performance and hosting are not impacted directly

Impact on site speed
There may be a slight impact on page load metrics (like LCP) if the tour loads immediately
However, this is generally minimal and manageable

Best Practice (Recommended)

To keep your site fast:

Use the tour below the fold (not at the very top), or
Load it on click (lazy load) instead of auto-loading

This way, your speed scores remain high while still offering an interactive experience.

So overall — yes, it performs well on websites, especially when embedded using best practices
