WordPress website launch checklist for UK agencies

TL;DR:

  • A comprehensive WordPress launch checklist ensures site security, compliance, and performance before going live. Using role-based sign-off and thorough testing minimizes post-launch issues and supports recurring revenue. Structured procedures help agencies protect their creative capacity and provide consistent client care.

Use this role-based WordPress website launch checklist to take a client site from staging to live without security gaps, GDPR exposure, or post-launch emergencies. The delivery lead owns sign-off; no item ships without evidence. Before anything else, run these on staging:

Every launch is also a revenue moment. Run the WordPress Profit Calculator now to see how much recurring care revenue is sitting in your existing client base.

What does a WordPress website launch checklist actually cover?

The pre-launch QA stage is where most post-launch tickets originate. A senior developer or QA lead should own this stage and sign off before the client sees anything on staging.

Content and UX checks come first. Run a link checker across every page, verify all images load at the correct resolution, and confirm redirects resolve in a single hop. Check every form: submission, notification routing, and confirmation message. Test payment flows if applicable, and verify site search returns relevant results.

Accessibility is not optional. A quick WCAG scan using an automated tool such as WAVE or axe catches the most common failures: missing alt text, poor colour contrast, and unlabelled form fields. Follow that with a keyboard-only navigation pass. These checks take under an hour and prevent the client tickets that arrive within days of launch.

The single most damaging pre-launch mistake is showing the client a half-finished staging environment and treating their feedback as a sign-off. Structure the client review around completed pages only, with a defined scope. Present what is done; keep work-in-progress out of the session entirely.

Pro Tip: Create a client review document that lists exactly which pages are in scope for sign-off. Anything outside that list is marked “not for review.” This alone cuts rework cycles by removing ambiguous feedback on unfinished work.

Security hardening and backup verification every launch must include

The single highest-impact security step is enforcing HTTPS site-wide and verifying the full certificate chain before anything else ships. Everything else builds on that foundation. Many standard security hardening steps are recommended for client-facing deployments, and a prepared senior developer can work through the core list efficiently.

Run every item on this list before go-live:

Security plugins handle some of this, but they cannot verify headers at the edge. Use an independent tool such as securityheaders.com to test CSP and X-Frame-Options on the production domain, and document the results in the handover pack.

Pro Tip: Build your hardening steps into a reusable project template or deployment script. Applied consistently, this removes the risk of a rushed launch skipping critical items under time pressure.

Performance, caching and SEO checks to complete before launch

The performance owner should record a Lighthouse snapshot on staging before DNS cutover, so any post-launch regression has a baseline to compare against. Target LCP under 2.5 seconds on mobile, CLS under 0.1, and TTFB under 800ms on key page templates, not just the homepage.

For a structured SEO workflow at launch, run Screaming Frog or a comparable crawler on the production domain within the first hour of go-live to catch any configuration errors that only appear in production.

Generic privacy policies leave sites non-compliant because every site uses a different combination of plugins and third-party integrations. Customise the policy to reflect the site’s actual processing activities, not a template.

The ICO’s guidance on PECR is the authoritative reference for cookie consent requirements in the UK. Direct the client to it during handover so they understand their ongoing obligations.

Deployment runbook: DNS, SSL, cache and rollback

Lower DNS TTL values to 300 seconds at least 48 hours before cutover. On deploy day:

Rollback procedure: revert DNS to the previous A record, restore the pre-launch database snapshot, clear all caches, and confirm the previous site is loading before notifying the client. The deploy owner signs off on rollback; no one else initiates it.

Handover pack and how to transition the client to a care plan

A handover is more than a credentials document. Handover packs that include restore proof and changelogs reduce post-launch emergency tickets and client anxiety. It is also the moment to convert the project into recurring revenue.

Include in every handover pack:

Use the handover conversation to walk the client through what ongoing maintenance covers: security updates, plugin management, performance monitoring, and emergency response. Then show them the numbers. The WordPress Profit Calculator takes under 90 seconds and shows exactly how much recurring revenue your agency could be capturing from your existing client base.

Making QA repeatable: role-based sign-off and the 115-point quality standard

Assign roles, not people, to each QA stage. When a team member leaves, the role and its sign-off requirements remain. A static checklist without assigned ownership is a liability; map every item to a role and record evidence.

The 115-point quality standard from The Ethical Agency spans development, client review, and controlled go-live. Adapt it to a three-stage workflow:

  1. Development sign-off (senior developer): code review, security hardening, accessibility scan, performance baseline
  2. Client review sign-off (account manager): scoped page list, feedback documented, written approval received
  3. Pre-launch verification (deploy owner): DNS, SSL, backups, smoke tests, rollback plan confirmed

Each sign-off record should include: role, checklist subset completed, evidence link or screenshot, and timestamp. Store these in your project management tool against the project.

Pro Tip: Maintain the sign-off template as a role-owned document in your project management tool. Duplicate it for every launch. Zero reliance on memory means zero missed items when the team is under pressure.

Typical timeline and effort for a standard agency WordPress launch

A small to mid-size site launch typically involves a senior developer, an account manager, and a QA reviewer across two to three days of focused effort.

Task Estimated hours
Pre-launch QA (content, UX, forms, accessibility) 2–3 days
Security hardening 1–2 hours
Legal and GDPR checks 1–2 hours
Performance checks and baseline recording 1–2 hours
Deploy, DNS, SSL, smoke tests 1–2 hours
Handover pack preparation 1–2 hours
Total two to three days

Factors that push effort upward: e-commerce with payment flows, multilingual configuration, complex redirect mapping from a legacy site, or a client with limited technical familiarity requiring extended training. Build these into your project estimate, not your support budget.

Practical tools and templates to run the checklist faster

Three categories are worth investing in: staging and deployment automation, QA and scanning tools, and client handover templates.

Category Examples
Staging and CI WP Staging, Local by Flywheel, DeployHQ
Backup and restore UpdraftPlus, WP Time Capsule, ManageWP
Security scanners securityheaders.com, SSL Labs, WPScan
Accessibility checkers WAVE, axe DevTools, Lighthouse
Cookie consent CMP CookieYes, Complianz, Cookiebot
Link and crawl tools Screaming Frog, Sitebulb, Broken Link Checker
GDPR scanning UK GDPR Compliance Checker (WordPress.org)

Why agencies should stop treating launch as a one-off event

Most agencies treat launch as the finish line. It isn’t. It’s the moment the client’s site becomes a live liability, and without a structured handover and a care plan in place, every future issue lands back on your team’s desk at the worst possible time.

The agencies that protect their creative capacity are the ones that productise launch. They run the same checklist every time, assign clear ownership, and use the handover conversation to transition the client onto a support arrangement. That conversation is not a hard sell; it’s a natural extension of the work you’ve just done. You’ve documented the site, verified the backups, and hardened the security. The care plan is simply the continuation of that standard.

The 115-point quality standard and role-based sign-off process described in this article are not bureaucracy. They are the difference between a launch that generates a support ticket on day three and one that generates a recurring revenue line instead.
