🚀 Maximizing Your Site’s Potential: A Comprehensive Pre-Launch Web Design Checklist
Launching a website isn’t just about going live—it’s about being ready. Whether you’re designing a site for a client or preparing your own business site, the pre-launch phase is critical. This is when your vision meets real-world functionality. It’s easy to get caught up in aesthetics and forget the technical groundwork, or vice versa. A well-structured pre-launch checklist ensures that your website isn’t just beautiful, but effective, fast, secure, and user-friendly from the first click.
✅ Mobile Responsiveness
With the majority of users now browsing from mobile devices, a responsive design is non-negotiable. This means your site must adapt fluidly across different screen sizes—from tablets to smartphones to extra-wide monitors. A site that looks stunning on desktop but breaks on mobile creates instant friction and drives visitors away. During the pre-launch phase, test every page on multiple devices and browsers. Buttons should be easy to tap, fonts should scale legibly, and layouts should not overflow or break. Tools like Chrome’s Developer Tools or BrowserStack can help simulate real-world mobile views to catch subtle layout issues before they go live.
📱 Mobile Responsiveness Pre-Launch Checklist
Layout & Structure
☐ All sections resize properly across devices (phones, tablets, phablets).
☐ No horizontal scrolling or broken overflow.
☐ Content stacks logically (e.g., 2-column desktop becomes 1-column mobile).
☐ Headers, sections, and footers are not overlapping or misaligned.
Navigation
☐ Mobile menu (hamburger) appears and functions correctly.
☐ Dropdowns and submenus are easily tappable.
☐ Sticky nav bars don’t obstruct content or interfere with scrolling.
☐ Logo is visible and links back to the homepage.
Text & Typography
☐ Body text is legible without zooming (minimum 16px).
☐ Headings scale appropriately and maintain hierarchy.
☐ Line spacing and padding enhance readability.
☐ Font families load correctly across devices.
Buttons & Touch Elements
☐ Buttons are at least 44x44px (thumb-friendly).
☐ Tap targets (forms, icons, CTAs) are spaced out properly.
☐ No hover-only interactions (they must work on tap).
☐ Tap feedback (color or animation) is visible on interaction.
Media & Visuals
☐ Images are responsive and do not stretch or pixelate.
☐ Background videos or parallax effects are optimized or removed for mobile.
☐ Sliders and carousels swipe smoothly with fingers.
☐ Icons and SVGs scale properly.
Forms
☐ Input fields fit within screen width (no cutoff).
☐ Keyboard adapts to input type (e.g., numeric for phone, email for email).
☐ Labels and error messages are legible and unobtrusive.
☐ Submit buttons are accessible and easy to tap.
Performance
☐ Page speed is optimized for mobile (test using Google PageSpeed Insights).
☐ Lazy loading is enabled for below-the-fold content.
☐ Critical CSS is loaded first to avoid content shifts.
Cross-Device Testing
☐ Tested on iOS and Android.
☐ Verified on major screen sizes: 320px, 375px, 414px, 768px.
☐ Browser-tested on Chrome, Safari, Firefox (mobile versions).
☐ No display issues when switching between portrait and landscape modes.
⚙️ Site Speed Optimization
A slow site is a silent killer of conversions. Users expect a page to load in under three seconds—any longer and they may bounce before even seeing your offer. Before launch, use tools like Google PageSpeed Insights, GTmetrix, or Lighthouse to identify and fix speed issues. Common culprits include oversized images, render-blocking JavaScript, unminified CSS files, and excessive HTTP requests. Compress images using tools like TinyPNG or WebP format, enable browser caching, and use lazy loading for below-the-fold media. A fast site doesn’t just retain users—it also ranks better in search engines.
⚙️ Site Speed Optimization Pre-Launch Checklist
Image Optimization
☐ Compress all images using tools like TinyPNG or WebP format.
☐ Use appropriate image dimensions to avoid unnecessary scaling.
☐ Implement lazy loading for below-the-fold images and media.
☐ Serve images in next-gen formats (e.g., WebP) where supported.
Code & Script Optimization
☐ Minify CSS, JavaScript, and HTML files to reduce file sizes.
☐ Combine CSS and JS files where possible to limit HTTP requests.
☐ Defer loading of non-critical JavaScript.
☐ Remove unused CSS and JavaScript files.
Caching Strategies
☐ Enable browser caching for static assets (images, CSS, JS).
☐ Implement server-side caching (e.g., using a caching plugin).
☐ Use a Content Delivery Network (CDN) to serve global visitors faster.
☐ Set appropriate cache headers in .htaccess or server config.
Hosting & Infrastructure
☐ Use a reliable, performance-oriented hosting provider.
☐ Ensure your server response time is under 200ms.
☐ Enable HTTP/2 if supported by your server.
☐ Use a fast DNS provider.
Database Optimization
☐ Clean up post revisions, spam comments, and trash items.
☐ Optimize database tables regularly (especially in WordPress).
☐ Limit the use of resource-heavy plugins or extensions.
☐ Use indexing on key database queries if custom-built.
Performance Testing Tools
☐ Run tests using Google PageSpeed Insights, GTmetrix, or Lighthouse.
☐ Review and address suggestions from performance audits.
☐ Test performance on both desktop and mobile profiles.
☐ Benchmark before and after changes to measure improvements.
🔐 Security Fundamentals
Security must be baked in—not bolted on. Before you launch, make sure your SSL certificate is active and every page redirects to HTTPS. This not only protects user data but also builds trust. Check your site for outdated plugins, unused themes, and admin panel vulnerabilities. Ensure your login page isn’t easy to brute-force, and consider adding two-factor authentication for administrators. If you’re handling user data or payments, compliance with regulations like GDPR or POPIA is also essential. Finally, set up regular automated backups—preferably stored offsite—so you can recover quickly if something ever goes wrong.
⚙️ Site Speed Optimization Pre-Launch Checklist
SSL Certificate Installation and HTTPS Enforcement
☐ Without HTTPS, user data (like form entries or login credentials) can be intercepted.
☐ Most modern browsers now display a “Not Secure” warning on non-HTTPS sites.
☐ Set up 301 redirects from HTTP to HTTPS to avoid duplicate content issues and ensure SEO consistency.
Update CMS, Plugins, and Themes
☐ Outdated software is one of the most common entry points for hackers.
☐ Delete unused themes and plugins to reduce your attack surface.
☐ Only use reputable, actively maintained plugins and themes from trusted sources.
Secure Administrator Credentials
☐ Use strong, unique passwords for all administrator and backend accounts.
☐ Change the default admin username (e.g., avoid “admin” or “root”).
☐ Limit the number of admin-level accounts and review user roles regularly.
☐ Rename the login URL (e.g., from wp-login.php) using security plugins to reduce brute-force attacks.
Two-Factor Authentication (2FA)
☐ Adds a secondary layer of protection even if the password is compromised.
☐ Many platforms support 2FA via authenticator apps, SMS codes, or email.
☐ Enforcing 2FA greatly reduces the risk of unauthorized access.
Implement Firewall and IP Blocking
☐ Helps protect against common threats like SQL injection, XSS, and DDoS.
☐ Block suspicious IP addresses or geographic regions known for bot attacks.
☐ Consider both server-side firewalls and application-level firewalls (like Wordfence or Sucuri for WordPress).
Regular Automated Backups
☐ Store backups offsite (e.g., on cloud storage like Google Drive, Dropbox, or a secure SFTP server).
☐ Ensure full backups include the database, files, themes, plugins, and media.
☐ Test your restore process at least once to confirm backups are viable.
Limit Login Attempts
☐ This helps prevent brute-force attacks where bots try multiple password combinations.
☐ Use plugins that log failed login attempts and temporarily ban IPs after multiple failures.
Security Headers Configuration
☐ Content-Security-Policy (CSP): Helps prevent cross-site scripting (XSS) attacks.
☐ X-Frame-Options: Protects against clickjacking by controlling frame embedding.
☐ Strict-Transport-Security (HSTS): Forces browsers to access the site only over HTTPS.
☐ Strict-Transport-Security (HSTS): Forces browsers to access the site only over HTTPS.
Scan for Malware and Vulnerabilities
☐ Use services like Sucuri SiteCheck, Wordfence (for WP), or your hosting provider’s built-in scanner.
☐ Check core files for tampering or injections.
☐ Schedule automated scans post-launch to run daily or weekly.
Permissions and File Hardening
Database Security
☐ Use a strong, unique database username and password.
☐ Rename default table prefixes (e.g., change wp_ to something obscure).
☐ Restrict database user permissions—only allow what is necessary (read/write, not full privileges).
Error Handling and Debug Settings
☐ Public error messages can leak sensitive information about your server or application.
☐ Disable error display in production environments by editing configuration files (e.g., WP_DEBUG = false).
☐ Set custom 404 and 500 error pages for a branded, user-friendly experience.
Security Monitoring Setup
☐ Set up notifications for suspicious activity (like multiple failed logins or file changes).
☐ Monitor logs (server, access, and error logs) regularly or automate this process.
☐ Some plugins and cloud services allow weekly or daily summaries of security events.
🔎 SEO Setup and Metadata
Search Engine Optimization (SEO) is not something you “add later.” It begins before your site ever goes live. Ensure every page has a unique title tag and meta description that not only include your focus keywords but also entice users to click. Your headings should be structured hierarchically using H1, H2, and H3 tags to communicate content hierarchy to both users and search engines. Every image should have descriptive alt text—not just for accessibility, but also for image-based search indexing. If your site uses WordPress, install an SEO plugin like Rank Math or Yoast and audit your pages before launch. Make sure your sitemap is ready and connected to Google Search Console.
⚙️ SEO Setup & Metadata Pre-Launch Checklist
Unique Page Titles (Title Tags)
☐ Ensure each page, post, and product has a unique <title> tag.
☐ Limit title length to 50–60 characters to avoid truncation in search results.
☐ Include the primary keyword near the beginning of the title.
☐ Make it human-readable—balance SEO with a compelling phrase (e.g., “Affordable Web Design Services in Durban | AddWeb”).
Meta Descriptions
☐ Write a custom meta description for every indexable page.
☐ Limit length to 150–160 characters.
☐ Use an action-oriented tone that encourages clicks.
☐ Include the target keyword naturally—Google may bold it in results.
Heading Hierarchy (H1–H6)
☐ Use only one H1 tag per page, usually for the page’s main title.
☐ Follow a logical structure (H1 > H2 > H3…) for subtopics and sections.
☐ Include target keywords in headers without keyword stuffing.
☐ Avoid using H tags for styling purposes alone—use CSS for formatting instead.
URL Structure & Slugs
☐ Use clean, keyword-rich URLs (e.g., /web-design-portfolio/ instead of /page?id=1432).
☐ Use hyphens (not underscores) to separate words.
☐ Keep slugs concise, descriptive, and lowercase.
☐ Avoid unnecessary stop words (e.g., “and,” “with,” “to” unless needed for clarity).
Image SEO (Alt Text & Filenames)
☐ Add descriptive alt attributes to every image.
☐ Use natural, short descriptions that reflect the image’s purpose (e.g., alt="Responsive web design layout").
☐ Rename image files to be meaningful (e.g., responsive-design.jpg instead of IMG_0032.JPG).
☐ Avoid keyword stuffing in alt tags—keep them honest and relevant.
Internal Linking Strategy
☐ Link to related pages using descriptive anchor text (e.g., “view our pricing plans” instead of “click here”).
☐ Make sure every important page is linked from at least one other page.
☐ Avoid orphan pages (pages with no incoming links).
☐ Create contextual links that add value and improve the site’s navigability.
Canonical Tags
☐ Use <link rel=”canonical” href=”…” /> on all pages to define the preferred version of each URL.
☐ Prevent duplicate content caused by URL variations, query strings, or pagination.
Robots.txt File
☐ Create a robots.txt file at the root of your domain (e.g., example.com/robots.txt).
☐ Allow crawling of public-facing pages and assets.
☐ Block access to private directories (admin areas, staging folders).
☐ Include a link to your XML sitemap if applicable.
XML Sitemap
☐ Generate an XML sitemap listing all indexable pages (tools like Yoast, Rank Math, or Screaming Frog can help).
☐ Submit the sitemap to Google Search Console and Bing Webmaster Tools.
☐ Link to your sitemap from your robots.txt file.
☐ Keep it updated automatically when content changes.
Mobile-Friendliness Confirmation
☐ Use Google’s Mobile-Friendly Test to confirm usability on mobile devices.
☐ Ensure text is readable without zooming, buttons are tappable, and layout adapts fluidly.
☐ Avoid mobile-only popups or interstitials that block content.
Page Speed Optimization
☐ Test using Google PageSpeed Insights or GTmetrix.
☐ Address any issues flagged under “Opportunities” and “Diagnostics.”
☐ Optimize Core Web Vitals metrics (LCP, FID, CLS).
Structured Data Markup (Schema)
☐ Add Schema.org markup to important content types (e.g., products, reviews, FAQs, events, articles).
☐ Use JSON-LD format where possible.
☐ Validate your markup using Google’s Rich Results Test.
404 Page and Redirects
☐ Create a custom 404 error page with navigation links or search functionality.
☐ Set up 301 redirects for any removed or renamed pages.
☐ Avoid redirect chains and loops.
Noindex/Index Meta Tags
☐ Use <meta name="robots" content="noindex"> only on pages that should not appear in search results (e.g., thank-you pages, staging areas).
☐ Double-check that your homepage and key pages are set to index, follow.
☐ Remove all noindex tags before launch unless intentional.
SEO Plugin or Toolkit Setup (If Using a CMS)
☐ Install and configure a reputable SEO plugin like Rank Math, Yoast SEO, or SEOPress.
☐ Review each page’s on-page SEO status using built-in checklists.
☐ Enable automatic XML sitemaps and breadcrumb support.
☐ Set global metadata defaults (e.g., for archives, custom post types, and taxonomies).
📊 Analytics and Tracking
Launching without analytics is like sailing without a compass. Before your site goes public, integrate Google Analytics (GA4) or your preferred analytics tool. This lets you track visitor behavior, monitor bounce rates, and evaluate traffic sources in real time. Don’t forget to set up conversion goals—like form submissions, purchases, or newsletter signups—to help measure success against business objectives. In addition, implement tracking pixels for any active ad campaigns (Facebook Pixel, LinkedIn Insights, etc.), so you can gather remarketing data from day one. It’s also wise to exclude your own IP and team members’ IPs from analytics to maintain clean data.
⚙️ Title
Install a Primary Analytics Tool (e.g., Google Analytics 4)
☐ Create a Google Analytics 4 (GA4) property for your site if one doesn’t already exist.
☐ Generate a Measurement ID (starts with G-) in the GA4 interface.
☐ Add the global site tag (gtag.js) just before the closing </head> tag on every page, or use Google Tag Manager (GTM) if managing multiple tags.
☐ Confirm that the tag is firing using Google Tag Assistant or the GA4 DebugView tool.
Set Up Google Tag Manager (Optional but Recommended)
☐ Create a Google Tag Manager container and install its two-part code snippet on every page—one in the <head>, one in <body>.
☐ Test installation using GTM’s Preview mode.
☐ Migrate other scripts (GA, Meta Pixel, Hotjar, etc.) into GTM for centralized tag control.
☐ Use variables and triggers to fire tags based on scroll depth, clicks, form submissions, or pageviews.
Define and Set Up Conversion Goals (GA4 Events & Conversions)
☐ Identify key business actions to track (e.g., contact form submission, newsletter signup, purchase completion).
☐ Configure event tracking using GA4’s “Enhanced Measurement” features and/or custom events.
☐ Mark important events as “conversions” in GA4 (e.g., generate_lead, purchase, sign_up).
☐ Test each event in real-time using DebugView.
Exclude Internal Traffic (Your IP and Team’s)
☐ Set up internal traffic filters in GA4 using a predefined rule (e.g., match your office’s static IP).
☐ Use browser extensions like GA Debugger to ensure you’re excluded from live data during testing.
☐ If working remotely, consider filtering by hostname, login state, or browser parameters (if IP filtering is unreliable).
Enable Enhanced Measurement Features in GA4
☐ Activate Enhanced Measurement to automatically track common interactions: Page scrolls, Outbound link clicks, Site search queries, Video engagement, File downloads
☐ Review settings per page type to disable irrelevant features (e.g., video tracking on pages without media).
Install Facebook Pixel (Meta Pixel) if Running Ads
☐ Create a Meta Pixel in your Business Manager.
☐ Add the base pixel code to every page via GTM or manually.
☐ Set up and test standard events such as: PageView, Lead, AddToCart, Purchase
☐ Use Meta Pixel Helper to confirm event firing.
Add Other Ad Platform Tracking Tags
☐ Install Google Ads Conversion Tracking if running paid search campaigns.
☐ Include LinkedIn Insight Tag, TikTok Pixel, Pinterest Tag, or Twitter Pixel where applicable.
☐ Ensure UTM parameters are added to all ad URLs to track sources in GA4.
Heatmaps and Session Recording (Optional Tools)
☐ Set up tools like Hotjar, Microsoft Clarity, or Crazy Egg.
☐ Install their tracking scripts site-wide.
☐ Configure behavior triggers (e.g., record only after 30 seconds or on specific pages).
☐ Test session recordings and heatmaps for functionality.
Link Google Search Console to Your Analytics Account
☐ Verify site ownership in Google Search Console using any method (HTML tag, DNS, GA, GTM).
☐ Submit your sitemap to Search Console.
☐ Link your Search Console property to GA4 to enrich SEO reporting.
☐ Monitor impressions, click-through rates, and indexed pages.
UTM Tagging for Campaign Tracking
☐ Use UTM parameters to track the performance of email, social, or paid campaigns.
☐ Standard parameters include: utm_source, utm_medium, utm_campaign, (Optional: utm_term, utm_content)
☐ Maintain a consistent naming convention and log all UTMs in a spreadsheet for reference.
Configure Data Retention and Privacy Settings
☐ Set GA4 data retention to the appropriate length (e.g., 14 months instead of the default 2).
☐ Enable IP anonymization if required by GDPR/POPIA.
☐ Customize cookie consent banners and tracking opt-in mechanisms for legal compliance.
Verify Data in Real-Time Dashboards
☐ Visit your live site in incognito mode and monitor real-time data in GA4.
☐ Confirm that key actions (e.g., form submissions, page views, outbound clicks) are triggering correctly.
☐ Check that conversions appear in the real-time panel.
☐ Use preview/debug tools in GTM to inspect events.
Backup and Document Your Tracking Setup
☐ Document where all scripts and tags are placed.
☐ Record trigger rules and event names for GA4 and GTM.
☐ Save your UTM template, pixel IDs, and tag versions.
☐ Export tag configurations from GTM as a JSON backup.
📝 Legal & Trust Pages
A professional website isn’t complete without foundational legal pages. These include a privacy policy, terms of service, refund or returns policy (if applicable), and a cookie notice if you’re collecting any kind of data. These pages do more than satisfy regulations—they build credibility. Visitors often scroll to the footer looking for reassurance, and the absence of such pages may signal a red flag. If you’re targeting international users, be mindful of laws like GDPR in the EU or POPIA in South Africa. It’s better to launch with boilerplate legal pages than none at all—though ideally, consult a legal professional for tailored content.

🧭 UX & Functionality Testing
User experience (UX) testing should simulate how real visitors will interact with your site. Walk through the customer journey—on both desktop and mobile—starting from the homepage through to your contact form, cart, or lead magnet. Do buttons work as expected? Are CTAs clearly visible? Does the menu function correctly on mobile? Test forms by submitting real entries. If you’re running an eCommerce platform, perform a mock transaction using various payment methods. Functional glitches at launch erode trust, especially when they block conversions. Also consider accessibility: screen readers, keyboard navigation, and contrast ratios must be tested for inclusivity.

📄 Content Review & Proofreading
Nothing undermines credibility like a typo or placeholder text. Review every headline, paragraph, product description, and footer note. Check for spelling, grammar, brand tone, and consistency. Also, verify that dynamic content—like blog feeds, testimonial sliders, or automated product grids—are populating correctly. If you’re using lorem ipsum or dummy content for layout testing, replace it completely before launch. Double-check contact details, social media links, and downloadable files. It’s surprisingly common for sites to go live with broken links or outdated information. A polished, error-free experience communicates professionalism and care.

🧰 Quality Assurance (QA) & Final Tech Checks
Before launch, clear your caching plugins and browser cache to see the site as a fresh visitor would. Check 404 pages and redirect loops. Validate your forms are sending to the correct email addresses. Ensure your favicon is displaying and your robots.txt file isn’t accidentally blocking indexing. Test across different devices and browsers—Chrome, Firefox, Safari, Edge, and mobile—because consistency matters. If you’re using third-party integrations (email tools, CRMs, booking systems), ensure they’re fully connected and responsive. Backup the final version of the site before going live, just in case a quick rollback is needed.
