A Website Redesign Checklist: Plan It Before You Design It

A website redesign is often treated as a design project. In practice, it is a business project with a design stage in the middle. The decisions that matter most, such as what the site is for, what content stays and how existing search traffic is protected, are made before anyone chooses a colour palette.

This checklist is written for business owners and marketing managers who are about to commission or manage a redesign. Work through it in order and you will avoid the most common and most expensive mistakes.

1. Be clear about why you are redesigning

“The site looks dated” is a fair starting point, but it is not a goal. Before you brief anyone, write down what the new site needs to achieve. Useful goals are specific and measurable, for example:

• More enquiries or quote requests from the website each month.
• Fewer support calls because customers can find answers themselves.
• A site your team can update without calling a developer.
• Faster pages, particularly on mobile.

Agree two or three priorities with the people who will sign off the project. When disagreements come up later, and they will, these goals settle them.

2. Record a baseline before you touch anything

You cannot tell whether a redesign worked unless you know where you started. Before work begins, record:

• Monthly organic traffic and your main landing pages, from GA4 and Google Search Console.
• The search queries and pages that bring in the most clicks.
• Conversions, such as form submissions, calls and sales, and the pages that drive them.
• Current page speed and Core Web Vitals results for key templates.

Export this data and keep it somewhere safe. It becomes your benchmark for the first few months after launch.

3. Audit your existing content

List every page on the current site. A crawling tool or your CMS export will help. For each page, decide on one of four actions:

1. Keep: the page performs well and is still accurate.
2. Improve: the topic is right but the content is thin, outdated or poorly structured.
3. Merge: several pages cover the same ground and would be stronger combined.
4. Remove: the page has no traffic, no links and no business purpose.

Be careful with “remove”. A page that looks unimportant may have backlinks from other websites or rank for a useful query. Check before you delete.

4. Plan the structure around your customers

Navigation should reflect how customers think, not how your organisation is arranged internally. Group services the way buyers search for them, keep the main menu short and make sure every important page is reachable within a few clicks.

Sketch a simple sitemap showing the main sections and the pages under each. Share it with a few customers or front-line staff and ask whether they could find what they need. This costs very little and often exposes gaps early.

5. Protect your search visibility

Redesigns are one of the most common causes of sudden drops in organic traffic. Usually the cause is avoidable. Build these steps into the plan:

• Map every old URL to a new one. Where a URL changes, set up a permanent 301 redirect to the most relevant new page, not simply to the home page.
• Keep what ranks. Carry across page titles, headings and core content for pages that already perform, unless you have a good reason to change them.
• Preserve metadata and structured data. Titles, meta descriptions, canonical tags and schema markup are easy to lose in a rebuild.
• Block the staging site. Keep the development version out of search results, then remember to remove that block at launch.

6. Write the content before the design is final

Designing around placeholder text is one of the main reasons redesigns overrun. Real content changes layouts: headings are longer, services need more explanation and images are not always available. Aim to have draft copy for the key pages ready before designs are signed off, so designers work with what will actually appear.

7. Decide on the platform and who will maintain it

Choose the content management system based on who will update the site and how often, not only on what the agency prefers. Ask practical questions. Who applies security updates? Who can add a new page? What happens if a plugin or module stops being supported? Agree maintenance responsibilities in writing before launch.

8. Build in accessibility and performance from the start

Retrofitting accessibility and speed is harder than designing for them. Include them in the brief:

• Sufficient colour contrast, readable font sizes and clear focus states for keyboard users.
• Meaningful alternative text for images and proper heading structure.
• Targets for Core Web Vitals: LCP of 2.5 seconds or less, INP of 200 milliseconds or less and CLS of 0.1 or less.
• Image sizes and formats agreed as part of the design system, not left to chance.

9. Test properly before launch

Allow real time for testing. A useful pre-launch checklist includes:

• Every form submits and the notifications reach the right inbox.
• Analytics and conversion tracking fire correctly on the new templates.
• Redirects work, with no chains or loops.
• Pages display correctly on common phones, tablets and browsers.
• No broken internal links or missing images.
• The XML sitemap lists the new URLs and robots rules allow crawling.

10. Launch carefully and watch closely

Avoid launching just before a holiday or your busiest trading period. Once live, submit the new sitemap in Search Console, check for crawl errors daily for the first week or two, and compare traffic and conversions against your baseline. Some movement in rankings is normal after a major change. Sustained drops on specific pages usually point to a redirect or content issue you can fix.

Key takeaways

• Set clear business goals and record a baseline before any design work starts.
• Audit content and decide what to keep, improve, merge or remove.
• Map old URLs to new ones with 301 redirects to protect search traffic.
• Write real content early and plan for maintenance, accessibility and speed.
• Test thoroughly, launch at a quiet time and monitor closely afterwards.
