A website redesign can make your business look sharper, feel more current and convert more visitors. It can also quietly break useful pages, search rankings and enquiry forms if the launch is rushed. A fresh appearance is only one part of the job; the new site must work better than the one it replaces.
That means reviewing the words, structure, speed, search visibility and customer journey together. Good website designmakes the experience clear, while careful website development ensures every button, page and form behaves as expected. Before your redesigned site goes live, work through these 15 checks.
1. Confirm the Site’s Main Purpose
Start by deciding what the website must help visitors do. Should they request a quote, book a consultation, buy a product, visit a store or understand a service? When every page tries to do everything, the next step becomes difficult to spot.
Choose one main action for each important page and make it easy to recognise. A service page may lead to an enquiry form, while a case study may guide the reader towards a consultation. The headline, copy and call-to-action button should all support that purpose.
Also agree on how success will be measured. Enquiries, sales, calls, downloads and booked appointments are more useful launch goals than vague targets such as “make the site modern.”
2. Protect the Pages and Data That Already Work
Before changing anything, review the current site’s analytics and search data. Note the pages that receive traffic, rank for useful searches or generate enquiries. These pages should not disappear simply because they do not fit the new menu.
Create a backup of the existing site and record important information such as page URLs, titles, forms and tracking codes. During a website redesign, this becomes your reference list. It helps the team preserve valuable content and quickly identify anything missing from the new version.
Keep the redesigned site on a private test link until it is ready. This gives the team room to review changes without showing unfinished pages to customers or search engines.
3. Redirect Every Old URL to the Right New Page
Changing a page address without a redirect sends visitors to a “page not found” screen. It may also cause the authority built by the old page to be lost. Create a simple sheet that pairs every old URL with the most relevant new one.
Use a permanent 301 redirect when a page has moved. Do not send every deleted page to the homepage; that is rarely useful to the visitor. Google treats redirects as a strong signal when deciding which URL represents a page, as explained in its canonical URL guidance.
After launch, test the old links one by one and check that each arrives at the intended destination without passing through several redirects.
4. Simplify the Navigation
Visitors should be able to understand the menu without knowing how your company is organised internally. Use familiar names such as Services, Products, About and Contact rather than clever labels that require interpretation.
Keep the most important pages within easy reach and group related information logically. If the menu has grown too large, remove duplicate links and move secondary items to the footer. Strong website design reduces the number of decisions a visitor must make at one time.
Test the structure with someone who was not involved in the project. Ask them to find a particular service or complete a task. Where they hesitate, the navigation probably needs another pass.
5. Treat Mobile as the Main Experience
The mobile version is not a smaller copy to inspect at the end. Text must remain readable, buttons need enough room to tap, forms should be comfortable to complete and important information should not disappear behind decorative effects.
Google primarily uses the mobile version of a site for indexing and ranking. Its mobile-first indexing guidancerecommends responsive layouts and equivalent primary content on mobile and desktop.
Test the site on actual phones, not only by narrowing a browser window. Check menus, sliders, pop-ups, videos and sticky buttons in both portrait and landscape views. Pay special attention to slower mobile connections.
6. Rewrite Copy for Clarity and Action
A redesigned page should not carry forward unclear copy simply because it already exists. Start each page with the information a customer needs most: what you offer, who it is for and why it matters.
Replace long introductions with useful headings, short paragraphs and specific proof. Avoid broad claims such as “best-in-class solutions” unless the page explains what makes the solution better. Buttons should describe the action—“Book a Consultation” is clearer than “Click Here.”
This is also an important part of landing page optimization. The message in an advertisement, email or search result should continue naturally on the page it opens. If the visitor was promised a free consultation, that offer should be immediately visible.
7. Test Every Conversion Path
Do not stop after checking whether a form can be submitted. Confirm that the correct person receives the enquiry, the visitor sees a helpful confirmation message and any automated reply contains the right information.
Test contact forms, booking tools, payment flows, phone links, WhatsApp buttons, newsletter forms and downloadable files. Try both valid and incorrect entries to make sure error messages explain what needs fixing.
For landing page optimization, remove fields that the sales team does not genuinely need at the first step. A shorter, clearer form often feels easier to complete. Track the final success screen or submission event so the team can measure results after launch.
8. Improve Speed Before Adding More Effects
Large images, autoplay videos, multiple font files and heavy animations can make a site impressive in a presentation but frustrating in daily use. Run key pages through PageSpeed Insights and examine them on a normal mobile connection.
For practical website optimization, compress images, use modern image formats, remove unused scripts and load below-the-fold media only when needed. Ask whether every animation improves understanding or simply adds waiting time.
Google’s Core Web Vitals guidance identifies three useful experience measures: loading speed, responsiveness after a tap or click, and visual stability while the page loads. Good targets are an LCP of 2.5 seconds or less, an INP below 200 milliseconds and a CLS below 0.1. These terms sound technical, but the goal is simple: pages should appear quickly, react promptly and avoid jumping around.
9. Optimise Every Image and Video
Upload images at the size they will actually be displayed. A huge photograph reduced by the browser still forces the visitor to download the huge file. Use descriptive filenames and add alternative text that explains meaningful images to people using screen readers.
Check cropping on mobile, especially for banners containing faces, products or text. Keep important subjects away from the extreme edges. Add a poster image to videos so visitors do not see a blank box while the file loads.
Avoid placing essential words inside an image. Search engines and accessibility tools understand normal page text more reliably, and the copy can adapt properly across screen sizes.
10. Preserve the SEO Foundations
Every important page needs one clear topic, a useful title, a natural description and a logical heading structure. Check that the main heading describes the page rather than repeating a slogan across the entire site.
An SEO friendly website also needs clean URLs, indexable content, relevant internal links and accurate canonical tags. Remove any temporary “noindex” instructions used on the test site before launch, and make sure the robots.txt file is not blocking important pages or resources.
This stage of website optimization is about helping search engines understand what each page offers. Think Tree’s technical SEO checklist covers the behind-the-scenes checks that support stronger performance.
11. Repair Internal Links and Submit the Sitemap
Click through links in menus, body copy, buttons, breadcrumbs and the footer. Update links that still point to test URLs, old page addresses or deleted files. A custom 404 page should help lost visitors return to useful areas of the site.
Generate a fresh XML sitemap containing the main pages you want search engines to discover, then submit it through Google Search Console. Google notes that a sitemap is a helpful discovery signal, although submitting one does not guarantee indexing.
An SEO friendly website should also connect related pages in a way that helps people move naturally from general information to more detailed services, examples or contact options.
12. Make the Site Easier for Everyone to Use
Accessibility improves the experience for people with visual, hearing, movement or learning differences, but many of the same changes help every visitor. Use readable contrast, clear labels, descriptive links and visible focus indicators.
Navigate the full site using only a keyboard. Confirm that menus, forms, pop-ups and sliders can be operated without a mouse. Add captions or transcripts where a video carries important spoken information.
The WCAG quick reference provides detailed accessibility guidance. At a basic level, users should be able to perceive the content, move through it and understand what will happen when they take an action.
13. Test Across Browsers, Screens and Real Situations
During the build, a page can behave perfectly on one laptop and fail on another device. Test current versions of major browsers and a useful mix of phone, tablet and desktop screen sizes.
Look for clipped text, overlapping buttons, broken layouts, missing icons and features that depend on hovering. Test with slow internet, empty search results, long names, incorrect form entries and unavailable products. These less glamorous situations often reveal the problems customers notice first.
Keep a shared issue list with the page, device, browser and screenshot for each problem. Give every issue an owner and recheck it after the fix.
14. Review Website Security, Backups and Access
Confirm that every page uses HTTPS and that there are no browser warnings caused by insecure images, scripts or forms. Update the content management system, themes and extensions, and remove anything the site no longer uses.
Strong website security also depends on everyday habits. Use unique passwords, enable multi-factor authentication where available and give each person only the access needed for their role. Do not leave former vendors or employees as administrators.
Set up automated backups and test whether one can actually be restored. A backup that has never been checked is only an assumption. Decide who will handle updates, security alerts and urgent fixes after launch.
15. Prepare a Launch and Monitoring Plan
Choose a quieter time to publish the new site and make sure the designer, developer, SEO specialist and decision-maker are available. Avoid launching just before a major campaign, public holiday or weekend if nobody can respond to a problem.
Immediately after launch, test priority pages, forms, redirects and tracking again. Verify the site in Search Console, watch for crawl errors and compare traffic and enquiries with the old-site baseline. Some fluctuation is normal, but sharp drops should be investigated quickly.
Do not treat launch day as the finish line. Review real visitor behaviour and continue improving pages based on evidence. Thoughtful monitoring turns a one-time project into ongoing website optimization.
Launch with Confidence, Not Guesswork
A successful website redesign balances appearance with usefulness. The site must be easy to understand, quick to load, safe to use and ready to support measurable business goals. Working through the checklist before launch is far less costly than discovering broken journeys after customers arrive.
