The ultimate website launch checklist (don't go live without it)
Launching a new website is the moment small oversights become public — and expensive. This is the pre-launch checklist we run on every build, grouped so nothing slips through the cracks.
Launching a website is a big undertaking, and launch day is exactly when small oversights stop being internal notes and start being live, public problems. A broken form, a missing analytics tag or a slow-loading page can quietly cost you leads from the very first visitor.
This is the checklist we run before any site we build goes live. Work through it section by section and you'll launch with confidence rather than crossed fingers. Bookmark it for your next website project.
The point of a checklist is to make the invisible visible. The errors that hurt most on launch day are rarely dramatic — they're the small, easy-to-miss things no one thought to test.
Strategy and content
A website only works if it's built for a goal and an audience. Confirm the foundations before you sweat the pixels.
- ✓ The site was built with a clear end goal in mind — and it actively helps you reach it.
- ✓ It's optimised for your target market, and the messaging genuinely speaks to them.
- ✓ Every required feature is present (for example, a shopping cart if you sell online).
- ✓ All copy is accurate, current and proofread — spelling, grammar, punctuation and capitalisation.
- ✓ Contact details are visible on every page, paired with a strong call to action.
- ✓ Copyright dates are present and set to the current year.
Design and usability
Visitors judge in seconds. These checks make sure the site looks the part and is effortless to use.
- ✓ The site is fully responsive and looks great on desktop, tablet and mobile — where most of your traffic now is.
- ✓ Images and videos load with no errors.
- ✓ Colours and typography are complementary and on-brand.
- ✓ Body text is comfortably readable on every device.
- ✓ The site is consistent across browsers — Chrome, Safari, Firefox and Edge.
- ✓ Your logo links back to the homepage.
- ✓ There's a designed 404 page for handling errors gracefully.
- ✓ Social media icons work and point to the correct, current accounts.

Technical and functionality
This is where launches quietly break. Test every interactive element as if you were a customer.
- ✓ Every link works and leads to the right place — a free tool like a broken-link checker speeds this up.
- ✓ External links open in a new tab so visitors don't get led away from your site.
- ✓ Forms submit correctly, the data lands somewhere known, and the right staff member is notified.
- ✓ An autoresponder confirms receipt to anyone who submits a form.
- ✓ Page load times are optimised — measure with Google PageSpeed Insights and act on the results.
- ✓ Core Web Vitals are in the green: loading, interactivity and visual stability all matter to both users and Google.

SEO and analytics
A site that launches without these is invisible to search and impossible to measure. Don't skip them.
- ✓ Every page has a unique title (around 60 characters) and meta description (around 155 characters) — no duplicates.
- ✓ Your target keywords appear naturally in titles, headings and body copy. Our guide to keyword research shows how to choose them.
- ✓ Images have descriptive file names and alt text so search engines understand them.
- ✓ Canonical URLs are set and your preferred domain is submitted to Google.
- ✓ 301 redirects map every old URL to its new equivalent, preserving rankings and backlinks.
- ✓ Analytics (GA4 or your chosen tool) is installed and confirmed to be recording visits.
- ✓ Structured data (schema) is in place so you're eligible for rich results and AI answers — see how schema boosts visibility.
Security and legal
Finish with the safeguards that protect your business and your visitors.
- ✓ HTTPS is active across the whole site (look for the padlock).
- ✓ The site is backed up and security-monitored from day one — see how to protect your site from hackers.
- ✓ A privacy policy and cookie notice are present where required.
- ✓ Everything has been tested again — on different browsers and devices, ideally by a few different people.
There's no single perfect formula for a website, but there is a reliable way to launch one: methodically, with nothing left to chance. Work through these five sections and your site will be ready to earn from its first visitor. If you'd rather have it handled end to end, our web design team builds and launches sites to exactly this standard.
Frequently asked questions
What should be on a website launch checklist?
A website launch checklist should cover five areas: strategy and content, design and usability, technical functionality, SEO and analytics, and security and legal. Within those, check responsive design, working links and forms, page speed and Core Web Vitals, unique titles and meta descriptions, 301 redirects, analytics tracking, HTTPS and a privacy policy before going live.
Do I need 301 redirects when launching a new website?
Yes, you need 301 redirects whenever URLs change in a new website. A 301 redirect points each old address to its new equivalent, preserving the search rankings and backlinks the old pages earned. Skipping them is one of the most common — and most damaging — launch mistakes, often causing a sharp, avoidable drop in traffic.
How do I check my website's loading speed before launch?
Check your website's loading speed with a free tool like Google PageSpeed Insights, which scores both mobile and desktop and flags specific fixes. Aim to get your Core Web Vitals — loading, interactivity and visual stability — into the green, since slow pages increase bounce rates and are penalised in search rankings.
What SEO checks should I do before a website goes live?
Before a website goes live, confirm every page has a unique title and meta description, target keywords appear naturally in headings and copy, images have alt text, canonical URLs are set, 301 redirects are in place, analytics is recording, and structured data is added so you're eligible for rich results and AI answers.
Is HTTPS required for a new website?
Yes, HTTPS is effectively required for a new website. Browsers flag sites without it as "not secure", which scares off visitors, and it's a confirmed Google ranking signal. Installing an SSL certificate to enable HTTPS across the whole site is a quick, essential step that should be completed before you launch.
