Page speed on a company site is whether a buyer on a phone reaches the enquiry button. If the first screen is late, the form stays empty. Measurement then reads the visit as a lack of interest. HED Creative does not sell a tool course. The scope carries three procurement questions: the mobile first screen, images, and third-party scripts. Berlin and Ankara check the same list.
Core Web Vitals is a procurement question
The three names mean this in a brief. When does the main content appear on a phone. When does the page answer a tap. Does the layout jump while it loads. That is the delay a buyer feels. A score is not written into the contract. What is written is which URLs are checked on a phone: the service that takes an enquiry, the product record, the contact page.
Images and third-party scripts
An uncompressed image delays the first screen. A chat box, a tag manager, a font file and a map that load before the page can answer freeze the button. Each script is named in discovery. If it earns its place, it stays and its cost is written. If it does not, it is out of scope. A pixel on every page is a speed decision, not decoration.
Measurement misreads a page that waits
On a slow page, form submits fall. A report can blame the ads. Comparing channels waits until the page answers. The event definition lives in the measurement plan. Speed is a condition of handover. They are not the same line of work. Both are written in the scope. A ranking promise does not enter that line.
The list that is handed over
The URLs that were checked, the image rule and the scripts that were stopped are written down. A picture of a score screen is not proof. Proof is the enquiry page opening on a phone and the form responding. One accountable partner applies the same list in both offices. Without the list, the speed work is not done.
To put speed on a scope line, start at website development. If search sits with the same owner, the SEO scope is a separate line. Related: website scope document.
