15 Things to Check Before Going Live With Your Website

You have spent months building. The design is pixel-perfect, the copy is polished, and the product is ready. Your finger is hovering over the "Deploy" button. But then, that familiar feeling of anxiety hits.

Did I check the mobile view? Did we remove the ‘lorem ipsum’ text from the privacy policy? Is the contact form actually sending emails to the right inbox?

Launching a website is a high-stakes moment. A single "silent fail"—like a broken signup link or a hidden noindex tag—can ruin your first impression, kill your conversion rate, and waste your marketing budget. In the world of web development, what you don't know can hurt you.

This is why pilots use checklists, and why web developers should too.

In this guide, we will walk you through the essential before launching a website checklist. We will cover the 15 critical manual checks you must perform to ensure stability, security, and SEO visibility. Furthermore, we will review the top 5 automated tools that can run these audits for you in seconds, giving you the confidence to press "publish" without the panic.

Why You Need a ‘Before Launching a Website Checklist’

It is tempting to think, "I built it, so I know it works." However, functionality in a development environment rarely translates perfectly to a live production server. The stakes are much higher once you go live.

The Cost of "Launch Day" Disasters

First impressions are sticky. If a user visits your site on day one and encounters a specialized 404 error or a broken payment gateway, they are unlikely to return. You only get one chance to launch. A checklist acts as your safety net against revenue-killing bugs.

SEO Implications are Immediate

Search engines like Google effectively start crawling your site the moment they discover a link to it. If you accidentally leave your staging environment's noindex directives on your live site, you tell Google not to list you. This simple mistake can set your organic traffic growth back by weeks or even months.

Automating the Process

While manual reviews are necessary, they are also prone to human error. You might check the home page but forget the "About Us" page. This is where automation comes in. Tools like Shipcheck and others we will review later can scan hundreds of pages in minutes, catching issues that the human eye often misses.

The 15-Point Pre-Launch Checklist (Manual Review)

Before we look at the automated tools, run through this manual before launching a website checklist. These are the fundamental pillars of a healthy launch.

Technical & Security Checks

1. SSL Certificate Validation

Launching without HTTPS is no longer an option. Browsers like Chrome will flag your site as "Not Secure," frightening users away immediately. Ensure your SSL certificate is active. Crucially, check for "mixed content" warnings—this happens when a secure HTTPS page tries to load an insecure HTTP image or script.

2. Robots.txt & Sitemap

The robots.txt file is the instruction manual for search engine crawlers. In staging environments, developers often set this to "Disallow: /" to keep the unfinished site private. You must remove this line when going live. Additionally, verify that your sitemap.xml is generated correctly and only lists pages you want indexed.

3. Site Speed Performance

A slow site is a rejected site. Use Google PageSpeed Insights to check your Core Web Vitals. You want to look specifically at LCP (Largest Contentful Paint). If your hero image takes 4 seconds to load, your bounce rate will skyrocket.

4. Mobile Responsiveness

Do not just resize your desktop browser window to check responsiveness. Test your site on actual devices or accurate emulators. Check that buttons are large enough for thumbs (touch targets), text is readable without zooming, and no elements overflow the screen horizontally.

5. Broken Link Sweeping

Click every link. It sounds tedious, but it is necessary. Check internal navigation, footer links, and social media icons. Ensure external links open in a new tab (target="_blank") so you do not send users away from your site permanently.

SEO & Content Checks

6. Title Tags & Meta Descriptions

Every single page needs a unique Title Tag and Meta Description. These are your "ad copy" in search results. A common mistake is duplicating the home page title across every sub-page. This confuses search engines and lowers click-through rates.

7. Header Hierarchy (H1-H6)

Structure matters. Your page should have exactly one H1 tag (the main topic). Subsections should be H2s, and points within those should be H3s. This hierarchy helps screen readers navigate your content and helps Google understand the semantic structure of your article or landing page.

8. Image Optimization

Giant images are the number one cause of slow websites. Ensure all images are compressed (formats like WebP are best) and properly sized. Also, verify that every image has descriptive alt text for accessibility and image search SEO.

9. Favicon Functionality

The favicon is the tiny icon that appears in the browser tab. It is a small detail that screams "professionalism." Ensure it loads correctly and looks good in both light and dark mode browser themes.

10. Spell Check & Grammar

Nothing kills credibility faster than a typo in a headline or leftover "Lorem Ipsum" text in a text block. Read your copy aloud to catch awkward phrasing. Do a distinct "placeholder hunt" to ensure no development notes were left in the code or copy.

Functionality & Compliance

11. Form Testing

Do not assume your forms work. Fill out your contact form, newsletter signup, and lead magnet forms. Verify two things:

1. The user gets a "Success" message or redirection.
2. You actually receive the data in your email or CRM.

12. Analytics Installation

You cannot improve what you do not measure. Check that your Google Analytics 4 (GA4), Facebook Pixel, or privacy-friendly alternatives like Plausible are firing. Check real-time reports while you browse the site to confirm data receipt.

13. Social Open Graph Tags

When someone shares your link on Slack, Twitter/X, or LinkedIn, what generates? If you haven't set Open Graph (OG) tags, it will likely be a random image or nothing at all. Use a social preview tool to ensure your shared links look enticing.

14. Legal Pages

To run ads or operate legally in many jurisdictions, you need a Privacy Policy and Terms of Service. Ensure these are accessible (usually in the footer). If you have users in Europe or California, ensure your cookie consent banners are functioning correctly.

15. 404 Custom Page

Users will eventually type a wrong URL. Do not show them a generic clear server error. Create a helpful custom 404 page that guides them back to the homepage or shows them popular links. This keeps users on your site longer.

Frequently Asked Questions (FAQs)

How long before launching a website should I start the checklist?

Ideally, you should run your first full audit on your staging environment one week before launch. This gives you time to fix complex technical issues like slow load times or SSL configuration errors. Run a final specific "sanity check" audit 24 hours before going live.

Is a manual checklist enough, or do I need software?

You can technically do everything manually, but it is risky. Software catches "invisible" errors that human eyes miss—such as broken internal redirects, missing canonical tags, or mixed content warnings deep in your blog archives. A hybrid approach (Manual for UX, Software for Code/SEO) is best.

What is the most common mistake people make before launching?

The most frequent and damaging mistake is leaving noindex tags on the production website. Developers often add these tags during the staging phase to keep the unfinished site private, but forgetting to remove them upon launch blocks Google from indexing your site entirely.

Can I run these checks on a password-protected staging site?

Yes! Tools like Shipcheck (via its Launch Mode features) and Checkbot (via your local browser session) allow you to audit password-protected or local environments. Most cloud-based SEO crawlers cannot access password-protected sites, so be sure to choose a tool that supports staging audits.
