Website Redesign Checklist: Plan, Build and Launch Without Losing Traffic

A website redesign checklist matters because redesigns rarely fail on design. They fail when pages that brought in traffic disappear, forms stop sending leads, or tracking breaks and nobody notices for a month. The checklist below is the order we work in on redesign projects, grouped into seven phases. Copy it into your project tool and assign an owner to every line.

How Do You Redesign a Website?

You redesign a website by planning first and designing second: set goals and a baseline, inventory every page and URL, plan the structure, then design, build, test, launch and monitor. Planning a website redesign mostly means deciding what the new site must protect (pages that rank, forms that convert, integrations that run the business) before anyone opens a design tool.

How to Use This Website Redesign Checklist

Work through the phases in order. Phases 1 and 2 happen before any design starts, because they decide what the new site must protect and improve. If the redesign also changes platform, for example from WordPress to Shopify or to a custom CMS, treat it as a migration as well and pair this list with our SEO migration checklist.

Phase 1: Goals and Baseline

• Write down why you are redesigning: more leads, better conversion, a new brand, a slow or hard-to-edit site, or a platform change.
• Turn each reason into a measurable target, such as form submissions per month or conversion rate on key pages.
• Record a baseline from GA4 and Search Console: traffic, conversions, top landing pages and top queries for the last twelve months.
• Note current Core Web Vitals for key templates (LCP, INP and CLS) so you can prove the new site is faster.
• List every form, integration and third-party script on the current site.
• Talk to a handful of customers, or read recent sales and support notes, to learn what visitors come to the site to do and where they get stuck.

Phase 2: Content and URL Inventory

• Crawl the current site with Screaming Frog or Sitebulb and export every indexable URL.
• Add traffic, conversions and backlinks for each URL from GA4, Search Console and a backlink tool.
• Mark each page keep, improve, merge or remove. Pages with traffic, conversions or links are never removed without a redirect.
• Build a redirect map: every old URL that changes gets a 301 to its closest new equivalent, not to the homepage.
• Save copies of current titles, meta descriptions and page content for pages that rank well.
• Run the current site through an SEO audit checklist so you fix existing problems instead of copying them.

Phase 3: Structure and Design

• Define the main user tasks, such as request a quote, compare plans or find a product, and design navigation around them.
• Plan the new sitemap and URL structure before wireframes. Keep existing URLs where they already make sense.
• Wireframe key templates: home, service or category, product or detail, article, contact.
• Set up a small design system (color tokens, type scale, buttons, form fields and spacing rules) so every template stays consistent after launch.
• Design mobile first, since that is often where most visits happen.
• Check color contrast, font sizes and focus states against WCAG accessibility guidelines during design, not after build.
• Write or rewrite copy before visual design is final, so layouts fit real content rather than placeholder text.

Phase 4: Build and Technical Setup

• Build on a staging site blocked from search engines with password protection or noindex.
• Set one title tag, meta description and H1 per page, and carry over the strong ones from the old site.
• Add structured data where it applies, such as Organization, Product, Article and FAQ schema.
• Optimize images (modern formats, correct sizes, lazy loading below the fold) and limit third-party scripts.
• Generate an XML sitemap and a clean robots.txt for production.
• Set canonical tags, and make sure pagination and filtered pages behave as intended.
• Rebuild tracking in Google Tag Manager: GA4 events, ad platform conversions and, for EEA visitors, a consent banner that supports Google Consent Mode v2.

Phase 5: Pre-Launch QA

• Test every form end to end: submission, confirmation message, notification email and CRM entry.
• Test the redirect map on staging where possible, and check for redirect chains.
• Crawl staging to find broken links, missing titles, duplicate content and orphan pages.
• Test on real iPhone and Android devices plus Chrome, Safari, Firefox and Edge on desktop.
• Run Lighthouse or PageSpeed Insights on each key template and compare against your baseline.
• Check tracking in GA4 DebugView and Tag Assistant so every conversion fires once.
• Confirm legal pages, cookie consent and accessibility basics such as alt text and keyboard navigation.

Phase 6: Launch Day

• Launch early in the week, never before a weekend or a major sale.
• Remove staging password or noindex, and check robots.txt allows crawling.
• Apply redirects and spot-check your top fifty old URLs.
• Submit the new XML sitemap in Google Search Console and Bing Webmaster Tools.
• Confirm the SSL certificate, the www or non-www version and HTTP to HTTPS redirects.
• Place a test conversion and confirm it appears in GA4 and your ad platforms.

Phase 7: The First Weeks After Launch

• Check Search Console daily for the first two weeks for crawl errors, 404s and indexing drops.
• Compare traffic and conversions against the baseline weekly, by page, not just site-wide.
• Fix any 404s with traffic or backlinks by adding redirects.
• Review session recordings with Microsoft Clarity or Hotjar to spot confusion in the new navigation.
• Keep the old site's crawl export and redirect map on file for at least a year.

How Do You Redesign a Website Without Losing SEO?

You redesign a website without losing SEO by keeping or redirecting every URL that earns traffic or links, preserving the content that ranks, and checking crawling and indexing closely for weeks after launch. The website redesign SEO checklist, pulled from the phases above, is short:

1. Export every indexable URL with its clicks, conversions and backlinks before design starts.
2. Keep URLs that already work; map every changed URL with a page-to-page 301.
3. Carry over titles, headings and body content on ranking pages, and improve rather than replace them.
4. Keep internal links pointing at final URLs, not at redirects.
5. Lift noindex and staging blocks on launch day and submit the new XML sitemap.
6. Watch Search Console coverage and page-level clicks weekly for at least two months.

How Long Does a Website Redesign Take?

A website redesign takes several weeks for a small marketing site with a clear scope, and a few months for a larger site with many templates, integrations, content rewrites or a platform change. Planning and inventory take the first stretch, design and copy the next, then build, QA and launch.

The phases themselves rarely cause delays. Waiting does: for copy, product photos, approvals from several stakeholders, or access to old hosting and analytics accounts. Assign one decision-maker, agree on feedback rounds up front and get content moving in Phase 1, and the timeline usually holds.

Common Website Redesign Mistakes

• Deleting pages that ranked. A cleaner sitemap is not worth losing the pages that brought traffic.
• Redirecting everything to the homepage. Search engines tend to treat this like a missing page, and visitors land somewhere unhelpful.
• Launching with noindex still in place. It happens more than anyone admits; check it on launch day.
• Rebuilding tracking last. Without matching events, you cannot tell whether the new site performs better.
• Designing with placeholder text. Real content breaks layouts that looked perfect in mockups.
• Choosing a platform by habit. A redesign is the right time to ask whether your platform still fits; our custom CMS vs WordPress comparison helps with that decision.

If you want a team to run the whole project, our website redesign services follow this checklist from baseline to post-launch monitoring, with the code and accounts owned by you. Before you start, a free audit of your current site will show what needs protecting and what needs fixing. More guides are on the 95 Solutions blog.
