Fix the PDP that sells — not a Lighthouse slide.
We measure the pages that sell, in the field, then fix the dominant constraint — third-party tags, queries, or origin — and write a budget so the next campaign cannot undo it.

LCP is a hero image and fourteen tags
The marketing site added another pixel. Checkout pays for it.
The real critical path first. Pixels, chat, and experiment tags come off checkout until they earn a place in the budget.

Admin and PDP die on sale day
The homepage is fine. The pages that sell are not. The database has been “fine” for two years.
Indexes, cache, and what must never hit origin when the catalog is hot — so admin and the PDP survive sale day.
We “optimized” and conversion did not move
A 100 Lighthouse on a blog post. The PLP still waits on a waterfall.
We re-measure the same selling URLs and leave a performance budget. A Lighthouse slide on an empty catalog is not the product.
Same selling URLs, before and after. The cost is written down.
The work we actually deliver.
Baseline on selling URLs
Field data plus lab, on home, PLP, PDP, cart, and checkout — not a blog post with a 100 Lighthouse.
Third-party tags
The honest conversation: keep, delay, or kill the pixel sitting on checkout.
Query plans and indexes
N+1, missing indexes, and exhausted pools before a bigger instance.
Cache before origin
What must never hit origin when the catalog is hot.
Edge and bots
Cache headers, stale-while-revalidate, and a plan for bot noise.
Watch after we leave
How to watch it after we leave, so the next sale does not surprise you.
Storefront, backend, or edge.
Storefront
CWV, assets, and third-party scripts are the drag.
A ranked list, then the top fixes, then a budget so the next campaign cannot undo it.
Backend
N+1, missing indexes, exhausted pools.
Query plans, indexes, and a cap on the worst endpoints.
Edge
Origin is doing work a CDN should do, or bots are the traffic.
Cache headers, stale-while-revalidate, and a plan for bot noise.
No junior hand-offs after the proposal.
You see the real storefront, not a slide deck.
Launch week is the start of the engagement.
Every page leads to a real conversation.
