A web product launch fails or succeeds long before launch day, usually on things that were never written down. This checklist covers everything you need to check across four areas: technical readiness, product/UX, search visibility (SEO, AEO, GEO), and post-launch monitoring, organised by when each task actually needs to happen: before launch, on launch day, and in the weeks after.
Quick-Answer Summary: The 10 Things to Check First
If you only have time for one pass, verify these before anything else:
- The SSL certificate is active, and the site loads on HTTPS everywhere
- Core user flows (signup, login, checkout/upgrade) work end-to-end on mobile and desktop
- Meta titles, descriptions, and heading structure (H1–H3) are set on every key page
- The site is submitted to Google Search Console with a sitemap
- Analytics and error monitoring are live and tested
- Privacy policy, terms of service, and cookie consent are published
- 404s, broken links, and redirect rules are checked
- Page speed is tested on mobile (aim for under 2.5s LCP)
- FAQ and schema markup are in place for AI search visibility
- A rollback/incident plan exists in case something breaks on launch day
Everything below expands on these in the order you'll actually need them.
Phase 1: Pre-Launch Checklist (Do This Before You Announce Anything)
Product and Technical Readiness
| Task | Why it matters |
| Test core user flows on real devices, not just emulators | Emulators miss real-world touch, network, and OS quirks that break conversions |
| Load test for expected launch-day traffic | Traffic spikes on launch day routinely reveal issues beta testing never surfaces |
| Confirm backup and rollback procedures | If something breaks post-launch, you need a documented way back, not a scramble |
| Verify data migration accuracy (if replacing an existing product) | Silent data loss during migration is one of the most common launch failures |
| Set up uptime and error monitoring (e.g., server response times, error rates, database performance) | You cannot fix what you cannot see. Monitoring must be live before launch, not added after |
UX and Conversion Readiness
| Task | Why it matters |
| Build a guided first-run experience (in-app tooltips, onboarding emails, or a walkthrough) | Users who don't reach an "aha moment" in the first session rarely return |
| Remove placeholder and lorem ipsum content | Filler text left in footers or empty states is one of the most common last-minute finds |
| Add clear calls-to-action on every key page | Every page should tell the visitor what to do next; don't make them guess |
| Check accessibility basics (alt text, contrast, keyboard navigation) | Accessibility gaps are both a UX and a compliance risk, and increasingly an SEO signal |
Legal, Security, and Compliance
| Task | Why it matters |
| Publish privacy policy, terms of service, and cookie consent | Required in most markets and a trust signal to both users and search engines |
| Confirm SSL certificate is active site-wide | HTTPS is a baseline ranking factor and a baseline trust factor; never launch without it |
| Review data handling against relevant regulations for your target market | Compliance issues discovered post-launch are far more expensive to fix |
SEO, AEO, and GEO Readiness
This is the section most launch checklists skip and the one with the most compounding value.
| Task | Why it matters |
| Set unique meta titles and descriptions on every page | Duplicate or missing metadata is one of the fastest ways to suppress rankings before you've even started |
| Structure headings (H1–H3) around real search queries | Clear, query-matched headings help both Google and AI answer engines match your page to a search |
| Write descriptive, keyword-relevant alt text on all images | Supports both accessibility and image search visibility; don't keyword-stuff it. |
| Add FAQ content answering real questions your audience searches | FAQ content is one of the most reliably extracted formats for AI Overviews and chat-based search answers |
| Implement FAQ, Organization, and Article/HowTo schema markup | Structured data gives search engines and AI systems an explicit, machine-readable way to understand your content |
| Do keyword research before writing final page copy, not after | Retrofitting keywords into finished copy produces weaker, more awkward targeting than building around it from the start |
| Prepare 3–10 launch-ready blog posts answering audience questions | A backlog of content ready at launch avoids a content vacuum in your first indexing window |
| Submit your sitemap to Google Search Console and verify robots.txt isn't blocking key pages | Indexing can take days to weeks starting this early; shortening that window |
| Set up Open Graph tags for social sharing | Affects how your product looks when shared, which affects click-through from social referral traffic |
Phase 2: Launch Day Checklist
| Task | Why it matters |
| Monitor dashboards continuously (errors, downtime, response times) | Launch-day traffic and edge cases surface issues. Beta testing didn't catch fast detection limits damage |
| Assign one person whose only job is watching monitoring dashboards | Under launch-day pressure, monitoring is the first thing to get deprioritised if it isn't someone's sole responsibility |
| Respond to comments, support requests, and mentions quickly | Early responsiveness shapes first impressions of reliability more than almost anything else |
| Remove any noindex tags left over from staging | A page accidentally left noindexed can go unnoticed for weeks and quietly kill its own visibility |
| Publish your announcement content (blog post, social posts, email) | Launch day is a marketing moment as much as a technical one. Don't let it pass silently |
Phase 3: Post-Launch Checklist (30–90 Days)
| Task | Why it matters |
| Wait for meaningful data before making changes | Early metrics are noisy; give it at least a few weeks before drawing conclusions |
| Track SEO KPIs alongside business KPIs, not instead of them | A short-term ranking dip on a low-value keyword can be irrelevant if qualified conversions are up |
| Continue publishing content against your keyword roadmap | SEO compounds: the sites that keep publishing; after launch, they are the ones still ranking a year later |
| Monitor Core Web Vitals and page speed on an ongoing basis | Performance can degrade quietly as content and features are added post-launch |
| Build backlinks through guest content, partnerships, and outreach | Off-page SEO becomes the primary lever for competitive keywords once on-page basics are solid |
| Review analytics for drop-off points in onboarding | The first 30 days of real user behaviour data will show you exactly where your funnel leaks |
Common Launch Mistakes to Avoid
- Skipping validation testing—products that skip structured beta testing before launch fail at meaningfully higher rates.
- Treating SEO as a post-launch task — sites that build SEO foundations before launch index and rank faster than those that bolt it on afterward.
- No incident plan — assuming nothing will break is the single most common last-minute launch regret.
- Launching without analytics live — you cannot evaluate a launch you didn't measure from minute one.
- Ignoring AI search formatting entirely — content that isn't structured for extraction (clear headings, direct answers, FAQ, schema) is invisible to a growing share of search traffic that now comes through AI overviews and chat-based assistants rather than traditional blue links.
