Diagnose before you redesign: the decision that changes the outcome

5 min read

The typical conversation starts like this: “We want to refresh our website, it’s very out of date and doesn’t represent us well.” The company knows something isn’t working. It doesn’t always know exactly what.

The standard response in the market is to ask for a brief, present design concepts and quote a redesign. It assumes that if the site isn’t working, the solution is a new one.

PTW doesn’t work that way, and there’s a concrete reason for it.

The problem with redesigning blind

A redesign without a prior diagnostic has a high rate of producing the same problem with better design.

If the current site generates no enquiries because the call to action is badly placed, a redesign that keeps the same navigation structure will produce the same result. If the services page doesn’t convert because the text is confusing, a redesign that keeps the same copy will have the same problem — just in a more modern typeface.

Design does not compensate for structure. A visually refreshed site with the same underlying problems is still a site that doesn’t perform.

What a diagnostic reveals

A proper diagnostic answers questions you can’t answer by eye:

Which pages get real traffic, and which are invisible? It’s rarely what you’d expect. Often the page the company considers central has close to zero organic visits, while a secondary page receives most of the traffic.

Where does the traffic come from, and what is that visitor looking for? Organic search traffic carries intent. If the keyword bringing the most visits has nothing to do with the company’s main service, there’s a misalignment between what the site communicates and what the market is searching for.

Where does the visitor drop off? Knowing at which point in the journey most visitors leave lets you identify the real problem. If the drop-off happens on the services page, the problem is how the services are described. If it happens on the contact form, the problem is the form.

Are there active technical problems Google is recording? 404 errors on pages that receive external links, pages accidentally excluded from indexing, load times over Google’s thresholds — none of these are visible without looking.

Can the existing content be salvaged, or does it need rewriting? Sometimes there are well-written pages that simply need better structure. Knowing this before a redesign can significantly reduce the cost of the project.

What changes after the diagnostic

With a diagnostic in hand, the project decisions are completely different.

Instead of “we want to redesign the site”, the conversation becomes: “the main problem is X, that requires these specific changes, and these other elements can be kept or updated with less investment”.

That defines the project scope better, the budget actually required, and the order of priorities. More importantly, it defines what to measure to know whether the project worked.

Without a diagnostic, the success criterion for a redesign tends to be subjective (“we like how it looks now”). With one, the criterion is concrete: the conversion rate improved, quality enquiries increased, rankings improved for the searches that matter.

When the diagnostic leads straight to a redesign

Not always. But when it does, that redesign rests on much firmer ground.

A diagnostic might conclude the site needs:

  • A full redesign (the communication and technical structure is broken)
  • Partial improvements (some problems are fixable without starting over)
  • Technical SEO only (the design is fine but the technical base has problems)
  • Mainly copy and information structure (the problem isn’t visual)

Each of those paths has a different cost and a different return. Knowing which one applies before committing to a budget is the difference between an informed investment and a bet.

When a diagnostic makes no sense

If the company doesn’t have a website yet, the diagnostic doesn’t apply — there’s nothing to analyse. The starting point in that case is web design and development directly.

It also makes no sense if the company has already done its own detailed analysis and is clear on the specific problems. In that case the diagnostic would be redundant, and the right move is to go straight to the solution.

For every other case — an existing site that doesn’t perform, an old site that “doesn’t represent the company well”, a site that generates traffic but no enquiries — the diagnostic is the most efficient step available.


PTW’s strategic diagnostic covers exactly this analysis: technical, SEO, communication and commercial. The output is a report with prioritised findings and a concrete roadmap, not a context-free list of errors.
