Use the deployment section as a model, but record the exact build, environment, and smoke-test steps for your own host.
Before you begin

What this lesson is really solving.

Test content, function, accessibility, performance, metadata, and links before deployment. Use the browser console, network panel, keyboard, device emulation, and at least one other real browser. Publish through a repeatable process and verify the production URL.

Why this works

Understand the idea before touching the steps.

Publishing is a release process: verify the artifact, route it through hosting, then observe it in production.

Do this

Follow these steps in order.

Take the action in each step; then use the deliverable below to prove the lesson is finished.

  1. 1

    Test navigation, forms, links, images, focus order, keyboard use, and responsive layouts on real narrow and wide screens.

  2. 2

    Check console errors, missing files, page title, description, favicon, not-found behavior, and secure HTTPS delivery.

  3. 3

    Compress assets, reserve image dimensions, remove unused code, and measure core performance in the target environment.

  4. 4

    Connect hosting and domain records using provider instructions, then verify both root and common URL variants.

Worked example

See the standard in context.

The tutor site receives a title and description, social preview, favicon, form destination, robots decision, and custom 404. A checklist catches a broken privacy link and a 4 MB hero image before deployment. The production form is submitted once end to end.

Quality check

Inspect before you move on.

  • Every internal route, external link, form, and interactive control was exercised.
  • The production site has HTTPS and no console or mixed-content errors.
  • Images, fonts, scripts, and third-party embeds are necessary and reasonably sized.
Make it real

Your deliverable

A live site plus a signed launch checklist covering content, function, access, speed, and metadata.

Common mistake

Watch for this

Calling the homepage done while links, form delivery, mobile overflow, or domain variants remain untested.

You’re ready when

Prove it—don’t just recognize it.

You can reproduce the release from source and verify the live version matches it.
