Field data first, lab data second
Chrome User Experience Report numbers are what Google uses. A Lighthouse run on a developer laptop over fibre is a debugging tool, not a measurement. We start with what your real visitors experience on real phones.

The problem
Speed work is usually sold as a package and delivered as a plugin. The score moves in the lab and nothing moves in the field, because the thing actually costing you Largest Contentful Paint was a hero image nobody resized or a third-party script loaded in the head.
How we do it
What the work actually involves
The ordered list, with expected gains
Each finding gets an estimated saving and an effort level. Frequently three changes account for most of the improvement and the rest is not worth buying — you should be able to see that and stop.
Third-party scripts audited by what they earn
Chat widgets, heatmaps, six analytics tags and a tag manager firing them all. Every one has a cost in milliseconds; few have an owner who can say what it returns. We put the cost next to the name.

Book 30 minutes with a strategist. No deck, no pitch — just answers about your situation.
Book a callDirectly, it is a small one — Core Web Vitals are a tiebreaker rather than a lever. Indirectly it matters much more, because a slow page loses people before they convert, and bounce behaviour feeds back into how the page performs. We sell this on conversion, not on rankings.
