Personalization without the bloat: a CMS-driven approach
Most personalization tools add 200ms of JS. Here’s how to do it server-side and stay fast.
Most personalization tools add 200ms of JS to your store. We run personalization through the CMS layer instead — server-rendered, zero added JS, full Lighthouse score.
The pattern
Identify the customer at edge (cookie, header, or session). Resolve their segment. Pull the matching content variant from the CMS at render time. Cache aggressively at the CDN with Vary on segment.
What we personalize
- Hero copy and image based on referrer + segment
- Featured collection ordering by purchase history
- PDP cross-sells by category affinity
- Email-capture popup framing by visit count
What we don’t
Pricing. We do not run personalized pricing without explicit program design. The fairness/regulation risk is not worth a 3% CR lift.
Personalization without latency is a competitive edge. With latency, it’s a tax.
