How to audit UX, technical aspects, and SEO before redesigning a website?

Before launching a redesign, it is essential to start with a rigorous audit. To maximize the results of your project and avoid common mistakes, first refer to our article "How to successfully redesign your website for better results," which sets out the strategic framework and objectives to aim for.

This practical guide complements the parent article by going into operational detail. You will find a step-by-step methodology for auditing user experience, technology, and SEO, tools to use, prioritization criteria, and concrete deliverables to request from your agency or team.

1. UX (User Experience) Audit

1.1. Analysis of visitor behavior and journey

Start by segmenting your data in Google Analytics. Inspect the paths that lead to conversions and those that fall short. Identify pages with high bounce rates and those with low average time spent. Conversion funnels reveal exactly where prospects are dropping off; combine this information with session recordings and heatmaps to identify unclicked elements, interrupted scrolls, and poorly optimized forms.

1.2. Navigation, structure, and usage scenarios

Evaluate the information architecture logic: the page hierarchy should reflect the priority paths of prospects and customers. Clear navigation reduces the number of clicks needed to reach essential information. Test the consistency of menu labels, the relevance of product filters, and the fluidity of the conversion funnel. For e-commerce sites, check the following: product page, shopping cart, payment, and confirmation pages; any friction detected becomes a priority for improvement.

1.3. Design, accessibility, and responsiveness

Readability, clickable target size, and contrast directly affect conversion. The audit also checks basic accessibility to ensure that your content remains usable by as many people as possible. Test micro-interactions, error messages, and form steps: a clear message often reduces abandonment rates. Document responsive design recommendations for mobile and tablet.

2. Technical audit

2.1. Loading speed and performance

Measure performance with PageSpeed Insights, Lighthouse, and server tools. Analyze time to first interactivity, blocking elements, and heavy third-party scripts. Identify unoptimized images, unused CSS, and caching opportunities. Performance simultaneously influences SEO and conversion rates.

2.2. Mobile compatibility and Progressive Web App

Check the display and behavior on mobile devices. If a PWA is being considered, document the technical requirements: service worker, caching, offline display. The audit must specify any discrepancies and improvements to be made in order to offer a mobile-first experience.

2.3. Technical structure, indexability, and redirects

Review robots.txt, XML sitemap, canonical tags, and redirects. Prepare a URL mapping and a precise 301 redirect plan to avoid any loss of traffic during migration. Identify broken links and orphan pages that need to be corrected.

2.4. Security and compliance

Check the HTTPS configuration, backups, protection against common attacks, and GDPR compliance on trackers and forms. For e-commerce, test payment flows and certificate management.

3. SEO audit

3.1. On-page optimization and markup

Check the title tags, meta descriptions, and Hn structure. Ensure that each page targets a clear intent and that priority keywords appear naturally in key elements. Check the implementation of structured data (products, breadcrumbs, etc.).

3.2. Content: quality, consolidation, and silo strategy

Identify high-performing pages and those that should be merged. Write briefs to enrich priority pages and define internal linking in line with your semantic cocoon to concentrate SEO juice on your business pages.

3.4. Backlink profile and risks

Analyze the inbound link profile to identify valuable sources and potentially toxic links that should be disavowed. Ensure that pages receiving backlinks remain accessible or are properly redirected during migration.

3.4. Monitoring positions and competitive benchmarking

Measure your current positions on essential keywords to set realistic goals. Study the structure and content of top-ranked competitors to identify opportunities for format, secondary keywords, and rich snippets.
