Why this matters

A website redesign is deceptively complex because it sits at the intersection of brand, technology, content, and SEO — and each of those stakeholders has different priorities. The designer wants a beautiful UI, engineering wants a clean codebase, marketing wants SEO preserved, and the CEO wants it done yesterday. The Gantt chart is what keeps these workstreams synchronized and prevents the project from becoming an 18-month odyssey.

When to choose this template

Use this template when you are redesigning your company website, migrating to a new CMS, or doing a major visual overhaul that requires coordinated design, development, content migration, and SEO work. It covers the full lifecycle from stakeholder interviews through go-live and post-launch monitoring.

Key considerations

Things to plan for before you start.

1Audit your current site's SEO performance before starting. Document every page's organic traffic, backlinks, and rankings. If you lose SEO during a redesign, it can take 6-12 months to recover.
2Content migration is always the bottleneck. You have more pages than you think, and each one needs to be reviewed, rewritten, or redirected. Start the content audit in the first month.
3Design system before pages. Build a component library first, then assemble pages from components. This prevents the 'every page looks different' problem and speeds up development.
4Plan your redirect map early. Every old URL needs to point somewhere — 301 redirects preserve SEO value. A missing redirect map on launch day means broken backlinks and tanking rankings.
5Test on real devices and browsers, not just Chrome on your MacBook. Safari, Firefox, mobile Chrome, and tablet viewports all have quirks that only surface in testing.
6Performance budget matters. Set a target for page load time (under 3 seconds) and largest contentful paint (under 2.5 seconds) before development starts. It is much harder to optimize after the fact.

Pro tips from experienced PMs

Hard-won advice to help you avoid expensive mistakes.

Get stakeholder sign-off on wireframes before moving to visual design. Changing layout in wireframes takes hours; changing it in high-fidelity designs takes days. Never skip this gate.

Use a staging environment that mirrors production from Day 1 of development. 'It works on my machine' does not count as QA.

Set a content freeze date 1 week before launch. No new pages, no copy changes, no 'just one more thing.' Content changes after code freeze introduce bugs.

Plan the go-live for a Tuesday or Wednesday morning. Never launch on a Friday (no support coverage for issues), Monday (team is still ramping up), or before a holiday.

Keep the old site running in parallel for 2 weeks after launch. If something goes catastrophically wrong, you can fail over to the old site while you fix the issue.

Common pitfalls to avoid

Mistakes that derail projects of this type.

Redesigning without a content strategy. A beautiful design with the same mediocre content is a waste of money. Content strategy should drive design, not the other way around.

Scope creep through 'just one more page.' Lock the sitemap after the design phase. New pages should go into a post-launch backlog, not into the current project.

Forgetting about forms, integrations, and third-party scripts. Your contact form, analytics, chat widget, CRM integration, and cookie consent all need to work on the new site. Test each one.

Not monitoring SEO for 4-6 weeks post-launch. Even with perfect redirects, rankings fluctuate after a redesign. Watch Google Search Console daily and fix crawl errors immediately.

Frequently asked

Is the Website Redesign template free?

Yes. The Website Redesign template is included in GANTT360°'s free plan. Create up to 3 charts for free with PNG export. For editable .pptx export and unlimited charts, upgrade to Pro at €12/month.

Can I customize this template?

Absolutely. Every element is editable — drag bars to change dates, add or remove tasks, rename groups, change colors with your own theme, and adjust milestones. The template is a starting point, not a locked layout.

What formats can I export to?

GANTT360° exports to editable PowerPoint (.pptx) with real shapes (not images), PDF (vector), and PNG. You can also generate a shareable link or embed the chart via iframe.

How long does a typical website redesign take?

For a mid-size corporate site (50-200 pages), plan for 3-5 months: 1 month for discovery and design, 6-8 weeks for development, 2-3 weeks for content migration, and 1-2 weeks for QA and launch. Larger sites with CMS migration or multilingual content can take 6-9 months.

Should we migrate CMS platforms during a redesign?

Only if the current CMS is a genuine blocker. A redesign plus a CMS migration is two projects disguised as one — each doubles the risk of the other. If you must migrate, do the CMS migration first with the old design, stabilize, then redesign. Or accept the longer timeline.

How do we protect SEO during a redesign?

Three non-negotiables: (1) Map every existing URL to its new URL and implement 301 redirects before launch. (2) Preserve page titles, meta descriptions, and H1 tags for high-traffic pages — rewrite them for quality, but keep the core keywords. (3) Submit the new sitemap to Google Search Console on launch day and monitor crawl errors daily for 4 weeks.
