Website Launch Checklist: What Should You Check?

Launching a new website without a meticulous QA checklist is the primary reason why 40% of first-time visitors leave a page within 3 seconds. Visual bugs on mobile screens, unoptimized images, or broken contact forms directly damage your brand's reputation and bottom line. This checklist outlines the exact verification protocol I apply as a graphic designer before publishing any digital project.

Why is a strict checklist needed if the website already looks great in testing?

A website that looks flawless on the developer's monitor can easily suffer from broken layouts, illegible typography, or slow load times on other screen sizes and browsers. Isolated testing creates a false sense of security that breaks down when real users arrive. When I build a presentation website, quality assurance involves testing across at least 5 distinct screen resolutions, as well as Retina displays and low-refresh-rate monitors. A structured checklist removes guesswork and prevents lost conversions caused by hidden technical flaws.

Which visual and branding assets must be reviewed right before launch?

Before going live, you must verify vector asset scaling, favicon compatibility, typography rendering, and strict adherence to brand color codes. A professional logo design must be exported in SVG format to remain crisp on 4K displays without pixelation or unwanted white background boxes on dark themes.

• Favicon & App Icons: Clean .ico and .png files in 32x32px, 180x180px, and 512x512px formats across browsers.
• Logo Variants: Primary logo, monochrome version, and a compact mark for the sticky navigation header.
• Font Consistency: Checking H1–H6 hierarchy, mobile scaling, and loading via @font-face to prevent layout flashes.
• Unified Palette: Ensuring CTA button colors match the established brand identity guidelines accurately.

How can I ensure images do not slow down website loading speeds?

Every graphic asset uploaded to the site must be compressed and served in next-gen formats like WebP or AVIF, scaled exactly to its display container. A raw 5 MB photograph straight from a camera will destroy page load performance and Google scores. Through performance-focused graphic design services, images are resized to a maximum of 1920px for hero banners and 800px for inline blog graphics before deployment.

• Lossless Compression: Utilizing tools like TinyPNG or ShortPixel to keep image file sizes below 150 KB.
• ALT Tags: Adding clear, descriptive alternate text (5–10 words) for accessibility and search engines.
• Explicit Dimensions: Defining width and height attributes to eliminate Cumulative Layout Shift (CLS).
• Lazy Loading: Enforcing native lazy loading for all images located below the fold.

What technical and functional checks are mandatory for mobile devices?

On mobile devices, all interactive elements must have a touch target of at least 48x48 pixels and remain easy to operate with one thumb. Over 65% of global web traffic originates from mobile devices, making mobile optimization the main priority rather than an afterthought. The mobile navigation menu must expand smoothly without obstructing scrolling or jumping unexpectedly. Input fields should automatically trigger the correct virtual keyboard (such as numeric keypads for phone fields). Verify that phone numbers in the header or footer trigger direct calls using tel: links. Test pages across Safari (iOS), Chrome, and Samsung Internet (Android) to catch browser-specific rendering bugs.

How do I test whether all links and contact forms function correctly?

Validating forms and internal links requires executing real user conversions and scanning the site for 404 error pages. Send at least 3 test submissions through every contact form to confirm notification delivery directly to your inbox without landing in Spam folders.

• Custom 404 Page: Include a helpful message, search bar, and a direct button back to the homepage.
• Form Validation: Display explicit error messages when required fields are missing or email formats are invalid.
• 301 Redirects: Set up permanent redirects if launching a new site that replaces an older URL structure.
• External Links: Ensure all outbound links open in a new tab (target="_blank" rel="noopener") to prevent traffic leakage.

What legal pages and privacy settings must be live on day one?

Any website collecting user data requires a Privacy Policy, Terms & Conditions, Cookie Policy, and mandatory regulatory compliance badges. Missing legal pages expose your business to severe fines and can block paid advertising campaigns on Google or Meta platforms. Your cookie consent banner must block tracking scripts (such as Google Analytics or Meta Pixel) until the user gives explicit consent. If offering paid services, display complete company details (tax registration number, registered address) in the footer for full commercial transparency.

How does optimizing for search engines and AI answer engines help before launch?

Implementing technical SEO and structured data prepares your website for both search engines and generative AI tools that synthesize direct answers. Integrating a modern strategy for GEO / AEO / AIO optimization ensures search algorithms and AI bots understand your site's structure accurately.

• Meta Titles & Descriptions: Unique titles under 60 characters and descriptions under 155 characters per page.
• Open Graph Tags: Custom preview titles and images when links are shared on social media or messaging apps.
• Sitemap & Robots.txt: Generate valid XML sitemaps and configure crawling rules before submitting to Google Search Console.
• Structured Data (Schema.org): Add Organization, LocalBusiness, or Service schema markups for enhanced indexing.

What free tools can I use for a quick pre-launch performance audit?

You can use Google PageSpeed Insights, GTmetrix, and Screaming Frog SEO Spider to run comprehensive performance and technical audits. Google PageSpeed Insights provides a performance score from 0 to 100 for both mobile and desktop, highlighting render-blocking JavaScript or CSS assets. GTmetrix lets you simulate load times from different geographical locations while reporting total page size and request counts. To discover broken internal links and missing alt tags, Screaming Frog is the most efficient free crawler for up to 500 URLs. Aiming for a score above 85 on mobile ensures a seamless user experience.
