Website Redesign Checklist 2026: What to Fix Before You Rebuild

Check the Pages and Forms Customers Rely on Before Changing the Design. This Checklist Covers Mobile Layout, Accessibility, Page Speed and Search Visibility.

Start a redesign by trying the tasks customers rely on today. Find a service from the homepage, call from a phone and test the estimate form. Record what works before deciding what to replace.

If your current site looks dated but still brings in leads, the wrong redesign can erase things that already work. If the site is slow, confusing or hard to update, a visual refresh alone will leave the real problems in place. A good website redesign starts with the existing site, the traffic it already earns and the actions you want visitors to take.

Start With the Problems, Not the Mockup

Before design work begins, write down what is failing now. That list should be specific. “The site feels old” is not enough.

  • Which pages get traffic but fail to produce calls, forms or sales?
  • Which pages are hard to read or use on a phone?
  • Which pages load slowly or shift around as they load?
  • Which services are buried in the navigation?
  • Which pages no longer match what the business sells?
  • Which updates require a developer because the site is too hard to manage?

This gives the redesign a job. It also gives you something to compare after launch. If the new site looks better but still has the same navigation problem, slow pages and weak service content, the project missed the point.

Before removing or replacing pages, review which URLs already earn impressions and clicks in Google Search Console. A page that looks outdated can still have search value. If a useful topic remains part of the business, improve the page or map it carefully to a relevant replacement instead of discarding it without evidence.

Speed Is a Design Requirement

Google still recommends good Core Web Vitals as part of a strong page experience. Its current guidance sets the “good” targets at 2.5 seconds or less for Largest Contentful Paint, under 200 milliseconds for Interaction to Next Paint and under 0.1 for Cumulative Layout Shift. Those metrics cover loading, responsiveness and visual stability. See Google’s Core Web Vitals guidance.

That matters during a redesign because design choices create performance costs. A large video hero, oversized images, heavy sliders, multiple font files and too many third-party scripts can make a new site slower than the one it replaced.

Performance work should happen during design and development, not after launch. Compress images before they reach the page. Give images defined dimensions so the layout does not jump. Load only the scripts the page needs. Test real templates instead of a blank demo page.

Mobile Needs Its Own Decisions

A desktop layout squeezed into a narrow screen is not a mobile design. Google’s page experience guidance still asks whether content displays well on mobile devices and encourages site owners to evaluate the overall experience rather than one isolated metric. Google’s page experience guidance is a useful reference during a redesign.

On mobile, the details change. Navigation has less room. Forms take longer to complete. Large headings can wrap into five or six lines. A button that looks fine with a mouse can be hard to tap with a thumb.

Test the real site at common phone widths before launch. Check the menu, service cards, forms, buttons, image crops, sticky elements and footer. Look for horizontal scrolling. Make sure the main action is easy to find without covering the content.

Accessibility Belongs in the Redesign Plan

Accessibility is easier to plan into a redesign than to bolt on later. The W3C’s WCAG 2.2 standard covers areas such as keyboard focus, target size, authentication and predictable help. WCAG 2.2 is the current W3C recommendation for web accessibility.

For a business site, start with practical checks. Text needs enough contrast. Form fields need clear labels. Buttons and links need visible focus states. Navigation needs to work from a keyboard. Images that carry meaning need useful alternative text. Headings should follow a logical order.

These changes help people who use assistive technology, and many of them also make the site easier for everyone else to use.

Search Visibility Is Broader Than a Standard Results Page

Search keeps changing. Google now reports more ways people discover websites through visual and AI-assisted experiences. A redesign should account for that wider search environment without chasing every new feature.

Use clear page titles, descriptive headings, useful copy, strong images and crawlable content. Keep important information in the page itself instead of hiding it inside graphics. Search visibility starts with a site that systems can access and people can understand. IMS also covers these fundamentals in its SEO services.

Keep the Search Value You Already Earned

A redesign can change page names, URLs, navigation and content all at once. That creates risk if the old site already ranks for useful searches.

Inventory the current URLs before launch. Keep valuable URLs when the topic is staying the same. When a URL must change, map the old address to the best new page with a permanent redirect. Do not send every old URL to the home page.

Keep internal links intentional. Service pages should link to related pages where the connection makes sense. Blog articles should support service pages with relevant context. An established business replacing an existing site can review IMS Website Redesign. A business starting without an existing site can instead review Website Design.

Before launch, compare the old and new site side by side. Your website design portfolio can also help you evaluate how navigation, content hierarchy and project presentation change across different business types.

Design for the Next Action

Most business websites have a short list of actions that matter. Call. Request an estimate. Book an appointment. Buy a product. Send a project brief.

A redesign should make those actions easier. That does not mean putting a giant button in every section. It means removing friction between the visitor’s question and the next useful step.

A service page should explain what the service is, who it is for, what problems it solves and what happens next. Contact forms should ask for information the business will use. Navigation labels should describe where the link goes. Calls to action should match the stage of the page instead of repeating the same phrase everywhere.

Google also warns against intrusive interstitials that block the main content. Full-screen promotions can frustrate visitors and make content harder to access. Google recommends less intrusive alternatives such as smaller banners.

Make the Site Easier to Maintain

The redesign is also a chance to fix the way the site is managed. Repeated content should come from shared components when possible. Service pages should have clear fields for the content that changes. Global calls to action, headers and footers should not require the same edit in ten different files.

This matters after launch. A business website changes. Services change. Staff changes. Offers change. Search strategy changes. If every small update risks breaking the layout, the site will get stale because nobody wants to touch it.

A maintainable site also makes future SEO work easier. You can add service content, improve internal links and publish articles without rebuilding the theme every time.

Know When a Redesign Is Worth the Work

A redesign makes sense when the current site is creating measurable friction. Common reasons include slow templates, poor mobile layouts, weak service architecture, outdated content, difficult editing and a design that no longer matches the business.

If the existing site has strong content and useful search visibility, keep what works and rebuild around it. If the structure itself is wrong, fix the structure before spending time on decorative details.

For an established business with an existing site, IMS Website Redesign focuses on improving the platform without treating the project as a cosmetic reskin. If you are starting from scratch, the Website Design service covers the new-build path. You can also review IMS case studies to see how different businesses organize services, navigation and conversion paths.
