Glossary

The vocabulary, without the hand-waving

Every term this site uses, defined in a paragraph, with why it costs a store money and how to check it on your own site. Written for owners, not for developers who already know.

LCP (Largest Contentful Paint): How long until the main thing on the page appears.
INP (Interaction to Next Paint): How long the page takes to respond when you tap it.
CLS (Cumulative Layout Shift): How much the page jumps around while it loads.
TTFB (Time to First Byte): How long the server takes to start answering.
Field data: Measurements from your real visitors, not a simulation.
Redirect map: The spreadsheet that decides whether a migration keeps its traffic.
Cart fragments: The WooCommerce request that keeps the mini-cart fresh — on every page.
Headless commerce: The storefront and the commerce backend are separate systems talking over an API.
Crawl budget: How much of your site a search engine bothers to fetch.
Faceted navigation: Filters that generate URLs — usually far too many of them.
Structured data: Machine-readable facts about the page, in a format crawlers parse.
Staging environment: A copy of the store where changes are tested before customers see them.
AOV (Average Order Value): Revenue divided by orders — the lever that is not conversion.
Cart abandonment: Checkouts started that never became orders.
WISMO: "Where is my order" — usually the largest support category a store has.
hreflang: The signal that tells search engines which language version to show.
Canonical URL: Which version of a duplicated page is the real one.
WooCommerce REST API: The interface a separate storefront uses to read your store.
Static rendering and revalidation: Pages built ahead of time and refreshed on a schedule or on demand.
Core Web Vitals: Google's three measures of how a page feels to a real visitor.
