The verdict in three sentences
Redesigning a site without a prior audit risks rebuilding what already worked and reproducing the real problems. A full audit costs 2,500 to 8,000 EUR and produces a prioritized deliverable: what to keep, fix, rebuild. Its payoff is twofold: precisely scoping the redesign budget and focusing effort on the 20 % of actions that carry 80 % of the gain.
The six audit tracks
A serious audit covers six dimensions, each with its tools and deliverables. This overview is what avoids blind spots before a redesign.
| Track | What we examine | Deliverable |
|---|---|---|
| Technical | Performance, Core Web Vitals, errors, security | Prioritized fix list |
| SEO | Indexing, tags, internal links, rankings | SEO action plan |
| UX / conversion | Journeys, funnels, conversion rate | Quantified UX recommendations |
| Content | Quality, duplicates, stale pages | Editorial map |
| Accessibility | WCAG 2.1 AA compliance | Non-conformance report |
| Analytics | Tracking reliability, missing KPIs | Measurement plan |
Cost, format and scoring grid
Price depends on site size and depth. An audit always ends with a score per track, making prioritization objective. Here are the 2026 benchmarks.
| Audit type | Scope | 2026 cost | Turnaround |
|---|---|---|---|
| Express audit | Technical + SEO, marketing site | 2,500 to 3,500 EUR | 5 to 8 days |
| Full audit | 6 tracks, business site | 4,000 to 6,000 EUR | 2 to 3 weeks |
| Deep audit | 6 tracks + e-commerce/app | 6,000 to 8,000 EUR | 3 to 4 weeks |
| Post-audit support | Prioritization guidance | 800 to 1,500 EUR | — |
Typical scoring grid (0 to 5 per track): a track scored 4-5 is worth keeping, 2-3 to improve, 0-1 to rebuild first. The redesign then focuses on the red tracks.
Mini case study
Claire is CFO of an industrial SME in Lyon considering a redesign quoted at 22,000 EUR. She first orders a full audit at 5,000 EUR. Result: SEO and content score 4/5 (keep), but performance (2/5) and conversion (1/5) drag the site down. The redesign is refocused on those two tracks, bringing the budget to 13,000 EUR instead of 22,000. The audit saves 9,000 EUR of unnecessary work and secures the existing SEO traffic.

Why audit before redesigning?
To separate what works from what blocks, and avoid rebuilding SEO or content that already performs. The audit scopes the budget and reduces the risk of losing traffic.
How much does a site audit cost in 2026?
From 2,500 EUR for an express technical and SEO audit to 8,000 EUR for a deep six-track audit of a complex site. Price follows site size and requested depth.
Which tracks are essential?
At minimum technical/performance, SEO and conversion. On an institutional or public site, WCAG accessibility becomes unavoidable.
Is an audit worth it against the cost of a redesign?
Yes: by refocusing the redesign on the real problems, an audit of a few thousand euros often avoids tens of thousands of euros of unnecessary work.
What does the deliverable contain?
A score per track, a list of actions prioritized by impact and effort, and a redesign budget estimate. It is a document directly usable to frame the RFP.
