The 15 things to check before your website goes live fall into six groups: content accuracy, brand consistency, visual QA at three viewports, working links and forms, performance and SEO, and security and accessibility. Nothing ships until every blocking item shows green.
Launching a website without a QA checklist is like sending an email without proofreading it: the mistakes are permanent and public. We built a 15-section checklist that every site must pass before deployment. Nothing ships until every blocking item shows green.
Content: No placeholder text. Correct business name, phone, address, and hours. No emojis (they look unprofessional in professional services). Brand consistency: brand colors applied throughout, real photos (not stock), founder headshots with matching color grading.
Visual QA at three viewports: desktop (1440px), tablet (768px), and mobile (375px). We capture automated screenshots at all three widths. Code reviews cannot catch visual bugs. Only screenshots can.
Every navigation link must resolve. Every form must submit successfully. Every booking embed must load and function. These are not unit tests. They are user journey tests: start as a visitor, end as a lead, and verify the lead actually appears in the CRM.
Performance: Lighthouse mobile score 90+, Largest Contentful Paint under 2.5 seconds, all images optimized, total assets under 1MB. SEO: complete metadata (title, description, keywords), JSON-LD structured data, sitemap, robots.txt, Open Graph tags for social sharing.
Security headers must be configured: X-Content-Type-Options, X-Frame-Options, referrer policy, and content security policy. Accessibility: skip navigation link, contrast ratios passing 4.5:1, keyboard navigation through all interactive elements.
