Most launch checklists read like a wish list. They tell you to make the site fast and accessible, then leave you to guess how. This one is different. It is the sequence we actually run before and after a site goes live, grouped so you can work through it without wondering what comes next.

Before you launch: content and structure

Start with the words, not the pixels. Read every page out loud. Check that each page has one clear job and one primary call to action. Confirm your page titles and meta descriptions are written, unique, and under the limits search engines respect. Make sure headings follow a real hierarchy, with a single H1 per page and H2s that describe the sections beneath them.

Then check the plumbing. Every internal link should resolve. Every image should have descriptive alt text. Forms should submit to the right place and send confirmation to the right inbox. If you are replacing an old site, map every old URL to its new home with a 301 redirect so you keep the ranking and trust you already earned.

Before you launch: technical checks

Test the site on a real phone, not just a resized browser window. Layouts that look fine on a laptop often break on a small screen, and most of your traffic is likely mobile. Check load speed on a normal connection and fix the obvious drags first, usually oversized images and render-blocking scripts.

Confirm your analytics and any conversion tracking fire correctly in a test session before launch, not after. Set up a custom 404 page that helps people find their way back. Verify SSL is active so the whole site loads over HTTPS. If you use a cookie or consent banner, make sure it works and defaults to the privacy-respecting choice.

Launch day: the switch

Take the site live at a quiet time for your audience, not the middle of a busy morning. Submit your sitemap to Google Search Console and Bing Webmaster Tools so search engines find the new structure quickly. Do a final crawl to catch any link that broke during the final push. Clear your caches, including any CDN, so visitors see the current version rather than a stale one.

After you launch: the part people skip

Launch is a milestone, not a finish line. In the first week, watch Search Console for crawl errors and pages that fell out of the index. Check your analytics to confirm data is flowing and goals are recording. Read the real session data to see where people actually land and where they leave.

Ask a few people outside your team to complete a core task, like booking a call or finding a specific service, and watch where they hesitate. Those small moments of friction are the cheapest wins you will ever get. Fix them while the project is still fresh in everyone's mind.

Keep the checklist honest

A checklist only helps if it matches how you actually build. Ours changes with every project, because a marketing site, a product launch and a content-heavy rebuild each stress different things. The habit that matters is separating content, structure and technical checks so nothing important hides behind something pretty.

If you want a second set of eyes on a launch, or a partner who handles design, build and the growth work that follows, we do this every week. Book a discovery call and tell us what you are shipping.
