Launching a website is the peak of months of work, but a rushed launch is one of the most expensive digital mistakes. A bug that surfaces after launch both damages brand credibility and costs several times more to fix than before release. A complete pre-launch checklist dramatically lowers that risk. In this guide from the PBDP blog we list every essential item, grouped, so nothing is missed when you go live.

1) SEO and structure

Write a unique SEO title and relevant meta description for every page; keep URLs clean and readable; prepare and test sitemap.xml and robots.txt; and enable structured data (Schema). The full task list is in our step-by-step technical SEO guide.

2) Performance and speed

Optimize pages against Core Web Vitals: compress images and lazy-load them, enable browser and server caching, and remove or defer non-essential scripts. Measure speed on mobile too, since most traffic comes from there.

3) Security

Activate an SSL/HTTPS certificate and set a forced redirect from http to https. Protect forms against injection and abuse, and for assurance run a security review or penetration test within our web security and pen-testing service.

4) Forms and conversion path

Fill and submit every contact, signup and inquiry form for real, and confirm the data reaches its destination (email or panel). Review success and error messages and test the CTAs. If you have a landing page, apply the conversion principles from the landing page guide.

5) Responsiveness and user experience

Review rendering on mobile, tablet and desktop at various sizes. Menus, footers and widgets must work on every device. Revisit design built on UI principles and validate user paths with a quick test.

6) Broken links and placeholder content

Run a full crawl to find and fix broken internal and external links. Remove placeholder text, temporary logos and lorem ipsum; shipping sample content is one of the biggest credibility hits.

7) Analytics and tracking

Install traffic analysis tools and, if needed, conversion tags before launch so you have data from day one. How to interpret this data is explained in web analytics. Without tracking, post-launch optimization is impossible.

8) Backup and recovery

Back up the initial version of the site and test that a restore actually works. Set the backup and migration strategy so that if anything breaks after launch you can roll back to a healthy version within minutes.

9) Domain, DNS and corporate email

Verify DNS settings are correct, the domain is active and its expiry date is safe. Set up and test corporate email on the new domain so official correspondence looks professional from day one.

10) Final review and post-launch plan

Browse the whole site once as a brand-new visitor and note every small issue. After launch the site is not abandoned either; it needs updates, monitoring and continuous improvement, covered by our website maintenance and support service.

11) Duplicate content

Before launch confirm that no two pages carry identical content; duplicate text confuses Google and splits authority between pages. Keep a unique title and body for every page and, where needed, point low-value duplicates to the main version with a canonical tag so topical focus is preserved.

12) Accessibility

The site should work for every user: review image alt text, adequate colour contrast, proper form labels and keyboard navigation. Accessibility both improves the experience and helps the crawler understand structure, and it is an inseparable part of professional design built on the same UI principles you apply elsewhere.

13) Final form and notification test

Before launch, simulate the whole conversion funnel as a real user would: sign in, fill the form, see the confirmation message and verify that the notification email or SMS actually reaches its destination. SMTP settings and any payment or SMS gateway must be tested on the live domain, because many faults only surface in production, not on staging. Run one pass of test data through the admin panel and then delete it, so your early reports are not polluted with sample entries. Finally, capture a short screen recording of the happy path; it becomes a useful reference for training and for confirming that everything still works the same way weeks later. Do this whole sweep on a real phone over cellular data, not just office wi-fi, so you catch the network conditions most visitors actually experience and fix slow or broken steps before they cost you real leads.

FAQ

How far before launch should I run this checklist? Allow at least a week; some items such as indexing and speed testing need time and iteration.

What is the single most important item? If we had to name one, it is the forms and conversion path, because they directly affect revenue and failures there silently cost money.

Should SEO continue after launch? Yes; SEO is an ongoing process. The roadmap is in the SEO content strategy article.
