Why relaunches fail
Relaunches are open-heart surgery on your marketing engine. Done well they lift conversions and rankings; done poorly they can cost 30–80% of organic traffic. The usual failure pattern: beautiful design, missing redirects, weak QA and no monitoring. This checklist reflects dozens of launches as a web design agency.
When to relaunch vs iterate
- End-of-life CMS or security risk
- Chronic Core Web Vitals failures
- Structural SEO issues (duplicates, cannibalisation)
- Business model or brand pivot
- Maintenance cost explosion
If only one factor applies, sometimes targeted fixes beat a full rebuild.
Phase 1 – Planning
1 Goals and stakeholders
Define measurable outcomes—leads, speed, conversion—and assign a single decision-maker.
2 Timeline
Typical SME marketing sites: discovery and IA 3–4 weeks, design 3–4 weeks, build 4–8 weeks, migration 2–4 weeks, QA 1–2 weeks, launch + 4 weeks watch—add 20–30% buffer.
3 SEO baseline crawl
Export URLs, titles, metas, canonicals, internal links; pull Search Console top pages and backlink targets.
4 URL mapping
Every old URL maps to new destination, 301, 410 or unchanged—this document is non-negotiable.
5 Content audit
Keep, merge, retire or rewrite—consolidation is a major SEO opportunity.
6 UX and conversion requirements
Wireframes before pixels; validate journeys for each segment.
7 CMS / stack choice
Compare performance, editor needs, SEO control, TCO—see Next.js when performance is paramount.
8 Keyword refresh
Relaunch is the moment to fix topic gaps—engage SEO early.
9 Conversion review
Keep what converts; redesign what data proves weak.
10 Tracking blueprint
GA4 events, consent, Tag Manager, server-side if needed—no launch without a measurement spec.
Phase 2 – Build
11 Staging
Block indexing until launch; password or robots disallow.
12 Redirect implementation
301 chains avoided; deleted pages 410 or purposeful redirect; never blanket-homepage dumps for content URLs.
13 On-page SEO
Unique titles, metas, single H1, clean URLs, image alt and compression, internal links updated.
14 Technical SEO
Sitemap, robots, canonicals, hreflang if multilingual, schema (Organization, Article, FAQ, LocalBusiness as relevant), HTTPS everywhere.
15 Performance
Target healthy Core Web Vitals on key templates—LCP, INP, CLS.
16–18 Mobile, cross-browser, migration QA
Real devices; Chrome/Firefox/Safari/Edge; crawl staging for broken links and missing assets.
19 Forms and CTAs
End-to-end tests including CRM and thank-you tracking.
20 Accessibility
Contrast, keyboard use, semantics—many EU sites face strengthened accessibility obligations.
Phase 3 – Launch day
21 Timing
Prefer Tuesday–Wednesday mornings—not Friday evenings.
22 DNS / TLS
Mixed content resolved; certs valid; apex vs www consistent.
23 Redirect smoke tests
Spot-check top traffic and backlink URLs immediately.
24 Search Console
Submit sitemap; inspect priority URLs; monitor coverage.
25 Go-live list
robots allows crawl; staging noindex removed; favicon and OG tags; consent banner functional; analytics live; backups of legacy site archived.
Phase 4 – Post-launch (4+ weeks)
26–30 Monitoring
Daily organic traffic vs baseline; fix new 404s fast; watch CWV field data; validate conversions; collect qualitative feedback (sales, support, Hotjar).
Classic SEO-killer mistakes
- No redirects
- Deleting high-equity URLs
- Slower new templates
- Broken tracking
- Editing live without staging
- Broken internal links from migrated content
- Staging robots left enabled
FAQ
Ranking recovery time?
With clean 301s and better tech, often weeks; without redirects, months or never.
Change URL structure?
Only with strong reason—every change needs redirects and risk assessment.
Cost ballpark?
Varies by scope—WordPress refits vs Next.js builds differ; add SEO support separately.
