Domain DNS

Before launch, verify the domain is pointing to the correct server and DNS propagation is complete (use whatsmydns.net to check). Set up WWW redirect to non-WWW or vice versa. Configure A record, CNAME, and MX record if email is needed.

Installation: SSL/HTTPS Launch

SSL must be installed before launch. Google demotes sites without HTTPS, and users see "Not Secure" in browsers. Install free Let's Encrypt or use hosting-provided SSL. Check for mixed content (HTTP links in HTTPS pages). Redirect HTTP to HTTPS via .htaccess or server config.

Backup: Backup Launch

Backup must be set up before launch, not after. Install a backup plugin (WordPress: UpdraftPlus) or backup script. Check if hosting provides daily backup. Test a restore from backup once before going live.

SEO

Every page needs unique title tags and meta descriptions. One H1 per page. robots.txt allows crawlers. sitemap.xml exists and is submitted to Google Search Console. Canonical URLs are correct with no duplicate content.

Installation: Analytics Launch

Install analytics before launch to collect data from day one. Options: Google Analytics 4 (free), Plausible.io (privacy-focused), Fathom, or StatPX (free tier available). Test tracking with real-time report.

Security Launch

Scan for vulnerabilities before launch using securityheaders.com (security headers) and ssllabs.com (SSL grade). WordPress: disable directory listing, change default admin username, remove unused themes/plugins, set up Fail2Ban or login attempt limiter.

Performance Speed

Before launch, test with PageSpeed Insights (Google) and GTmetrix. Goals: LCP ≤2.5s, FID ≤100ms, CLS ≤0.1. All images must be compressed and have width/height attributes. CSS/JS minified and images lazy-loaded.

Mobile Responsive

Test in Chrome DevTools: F12 → Toggle Device Toolbar. Test multiple viewports: 375px (iPhone SE), 768px (iPad), 1024px (tablet landscape). Verify text is readable, buttons are tappable, no horizontal scrolling.

Frequently Asked Questions (FAQ)

Should you launch a website at night?
It's recommended to launch during the lowest-traffic period — for Thai sites that's 01:00-05:00 — to reduce the impact if problems occur. The dev team may be sleepy, but if errors happen, fewer users are affected than during the day.
Do you need a Staging Environment before launching?
If the site is important, high-traffic, or E-commerce, it's highly recommended. Staging = a copy of production used to test changes before deploying live. Many hosts offer one-click staging, such as WP Engine and Kinsta; with a regular host, use a subfolder or subdomain instead.
How fast does Google index a new website?
There's no fixed timeframe — generally 1 week to 3 months. What you can do is submit sitemap.xml in Google Search Console, request indexing via the URL Inspection Tool, and use IndexNow to submit URLs immediately. A brand-new site may take longer than one with history.
What do you need to do after the launch is complete?
After launch: monitor analytics daily, check uptime with UptimeRobot or Better Uptime, submit your sitemap in Search Console, publish content consistently, do backlink building, submit to relevant directories, and monitor rankings with Google Search Console.
