Core Web Vitals
What are Core Web Vitals?
Core Web Vitals are the three measurements Google uses to score how a page actually behaves for the person loading it.
The three are Largest Contentful Paint, how long the main content takes to appear; Interaction to Next Paint, how quickly the page answers a tap; and Cumulative Layout Shift, how far the page moves around while it is still loading. Google's threshold for the first one is two and a half seconds.
We measured 27 storefront sites on W 231st Street and Broadway in Kingsbridge in August 2026. 24 of them took longer than three seconds to show their main content, and the middle of the pack took nine. Speed figures are lab measurements taken under controlled conditions, not readings from real visitors' phones.
This is the measurement, not the fix. A site that fails it is usually carrying photos nobody compressed, a page builder's worth of code the page never uses, or both.
Every plan on the board is built for the phone first, which is where these three are hardest to pass. See the board
Every word we use, in plain English.
