What to Check Before Launching a Website?

Launching a website without rigorous technical and visual checks can lead to losing your first visitors and damaging your brand image. As a graphic designer, I have seen numerous projects where small details, from unoptimized images to broken forms, compromised the launch. Here is the complete checklist I use before publishing any project.

Why do I need a checklist before publishing my website?

A checklist prevents costly mistakes that can drive clients away within the first few seconds of launch. When building a presentation website, it is easy to overlook technical details while focusing on copy and visuals. Studies show that 88% of users do not return to a website after a bad user experience. Systematic verification reduces the risk of unfinished pages, display glitches on mobile devices, or slow loading times. Furthermore, a clean launch ensures proper indexing by search engines and delivers a professional impression from day one, much like a flawlessly executed visual identity package.

What visual and design checks should I perform on mobile?

On mobile devices, you must verify text readability, button sizes, and element spacing across at least three different screen resolutions. Over 60% of web traffic comes from smartphones, which means the mobile view is effectively the primary version of your business.

Mandatory mobile visual checks include:

• Font readability: base text size should be at least 16px to prevent automatic zooming on screens.
• Touch target sizes: buttons and links must have a minimum clickable area of 48x48 pixels.
• Navigation menu: verify that the hamburger menu opens smoothly without covering critical page content.
• Images and banners: ensure that graphics created through graphic design services are not cropped or distorted on small screens.

How do I ensure images do not slow down page speed?

Images must be optimized in size and format before being uploaded to the server, without sacrificing visual quality. A web page taking longer than 3 seconds to load loses roughly 40% of its visitors. To maintain a fast site, convert all graphical files to WebP or AVIF formats and limit individual image sizes to 150-200 KB maximum. For instance, a main hero banner should not exceed 1920px in width and 250 KB in file size. Always set explicit width and height attributes to prevent layout shifts during loading. Optimizing web images is just as critical as prepping print files for packaging or print collateral.

Which visual identity elements must be aligned across all pages?

Brand colors, typography, icon styles, and the favicon must be 100% consistent across every single page of the site. Visual discrepancies create confusion and lower visitor trust in your business. Check that HEX color codes match your brand guidelines and that no extra secondary fonts were loaded by accident, which slows down performance. Additionally, a vector logo design in SVG format should be placed clearly in the header and footer, with adapted versions for light and dark backgrounds. Don't forget the favicon (the browser tab icon), provided in ico and png formats at 32x32px and 180x180px for Apple devices.

How do I test if all links and forms work correctly?

Manual testing of every form and automated scanning of internal and external links are mandatory steps before launch. A single broken contact form can mean dozens of lost leads during your first month online.

Functional verification steps include:

• Submitting test messages through all forms (contact, quote request, newsletter sign-up) and confirming email notifications arrive.
• Checking the Thank You Page and on-screen confirmation messages.
• Identifying broken links (404 errors) using a free tool like Screaming Frog SEO Spider.
• Testing social media sharing by validating Open Graph tags via Facebook Sharing Debugger.

What technical SEO and visibility settings need to be configured?

You must set up Meta titles, descriptions, the sitemap.xml file, robots.txt, and the Google Search Console integration. Without these settings, search engines will not index your pages correctly or quickly. Today, it is equally vital to prepare your site for AI-driven search engines using modern GEO / AEO / AIO optimization techniques. This involves structuring data clearly (Schema.org), providing direct answers to common customer questions, and optimizing content for conversational queries. A clean semantic structure helps both Google and AI assistants understand exactly what services you offer.

What are the mandatory legal requirements for a business website?

A business website must include a Terms and Conditions page, a Privacy Policy (GDPR), a Cookie Policy, and visible legal disclaimers required in your jurisdiction. Missing these pages can lead to substantial fines from regulatory authorities. In the footer, display your complete business details (Company Name, Tax ID, Registration Number, Registered Address). Additionally, if you run analytics scripts such as Google Analytics or Facebook Pixel, you must implement a cookie consent banner that blocks scripts until the user explicitly opts in.

How long does final pre-launch testing take?

Final testing usually takes between 4 and 8 hours for a standard 5-10 page presentation website. This stage should never be rushed or combined with the official launch day. It is best to allocate a full day for testing in a staging environment and schedule the actual go-live for a Tuesday or Wednesday morning. Avoid launching on Fridays or weekends, because if unforeseen technical issues occur on the server or with DNS propagation, technical support or your designer may be harder to reach.
