A website redesign is an expensive decision. When a business starts with colours, layouts or templates before defining the real problem, it can end up with a more attractive version of the same underperforming website. A website audit before redesign should therefore answer three questions: what works, what blocks the result and what the new website must change first.
Why audit before redesign?
Once the new design is complete, many important decisions are already locked into the structure, content and technical solution. A late audit often identifies issues whose correction requires more budget and another round of work.
An initial diagnostic creates a shared basis for management, marketing, copywriting, design and development. Everyone knows why a change is being made and how the result will be evaluated.
What should a pre-redesign audit establish?
- The main business goal: whether the website should generate an enquiry, purchase, registration, booking or another specific action.
- Current barriers: technical issues, mobile friction, unclear navigation, a weak offer, missing proof and unsuitable calls to action.
- Content that already works: pages, arguments and elements worth preserving instead of removing everything by default.
- Target audiences: who uses the website, what they need to know and which concerns the new website must resolve.
- Technical constraints: performance, indexation, URL structure, metadata, mobile behaviour and migration requirements.
- Priorities: what belongs in the first version, what can be added later and what is merely cosmetic.
A redesign does not automatically solve conversion
A new visual system can increase trust and improve usability, but it cannot by itself fix an unclear offer, the wrong target audience or a missing reason to buy. Design problems must be separated from communication, process and business-logic problems.
What a useful agency brief looks like
A good redesign brief says more than “we want a more modern website”. It defines the main goal, priority user journeys, important audiences, content layers, technical requirements, proof elements and measurable conditions for success.
A SIGEL report can act as an external input for an agency or internal team. It ranks issues by impact and effort, turning the brief from a wishlist into a decision map.
What should be kept from the current website?
A redesign does not have to mean discarding everything. If existing URLs attract organic traffic, contain useful information or have external links, they should be retained, redirected correctly or deliberately reworked. The same applies to effective arguments, testimonials, forms and parts of the customer journey.
Technical SEO during a redesign
Changing URLs, structure or technology creates a risk of losing indexation and organic visibility. Before launch, the project should address canonical URLs, sitemap, robots.txt, internal links, redirects, metadata, mobile content and performance. An audit before redesign brings these requirements into the brief before they become an emergency after launch.
Recommended process
- map the current website and its goals,
- run technical, UX and communication diagnostics,
- rank issues by business impact,
- create a brief for structure, content, design and development,
- validate mobile, indexation, calls to action and the main journey before launch,
- compare real post-launch behaviour with the original hypothesis.
When should the audit be ordered?
Ideally, before wireframes and visual design begin. If the redesign is already under way, the audit can still help before the structure is locked or before final launch. The later a problem is discovered, the more expensive it usually becomes to correct.
