Service 02 of 04
A fixed-fee diagnostic. I measure your site the way Google does, find the causes, and hand your team a ranked backlog.
A Lighthouse score is one test on one simulated phone. Google’s Core Web Vitals assessment uses 28 days of real visits from Chrome. A site can score in the 90s in the lab and still fail in the field, and the reverse. The diagnostic measures both and shows which one is costing you.
Scope
Core Web Vitals from real-user data and lab tests, side by side, on the pages that carry your traffic and your conversions
Every third-party script and tag on those pages, what it weighs and what it blocks
Technical SEO: crawling, indexing, redirects, structured data and international setup
The templates behind your key pages, so one fix covers many URLs
A written audit with the root causes
A backlog of user stories your developers can start on
An executive readout, as a document and a deck, with the changes that matter most
The data: a tag census spreadsheet and the Core Web Vitals dataset
About 3 weeks from access to readout.
