The verdict in three sentences
On a B2B office furniture website, a slow catalogue and configurator cost quote requests directly, especially on mobile, where close to half of buyers arrive. A Core Web Vitals audit at EUR 1,500 to 4,000 pinpoints the causes, then EUR 4,000 to 12,000 of fixes usually bring LCP under 2.5 s and INP under 200 ms. The 2026 order of magnitude for the return: 12 to 25% more quote requests within three to six months, which pays back the spend with a handful of fit-out orders.
Why an office furniture site loses leads
A manufacturer in Eindhoven or Leicester selling to fit-out contractors, facility managers and CFOs typically lists 1,200 SKUs with variants (finishes, frames, sizes), a 3D or 2D configurator and a multi-product quote form. Those three building blocks are exactly what drags Google's metrics down.
| Observed symptom | Metric affected | Common cause | Google "good" threshold |
|---|---|---|---|
| Product page renders in 4 to 6 s | LCP | 1.5 to 3 MB JPEG photos, no CDN | < 2.5 s |
| Configurator freezes on click | INP | 3D JavaScript loaded upfront, 800 KB to 2 MB | < 200 ms |
| Page "jumps" while loading | CLS | Cookie banners, images without dimensions | < 0.1 |
| Slow catalogue filters | INP | Full list reload on every filter | < 200 ms |
| Abandoned quote form | INP + TTFB | Third-party CRM and chat scripts not deferred | TTFB < 800 ms |
| Poor ranking on "office furniture manufacturer" | All three | Unfavourable page experience signal | 75% of visits green |
The key point: Google scores the 75th percentile of real visits (CrUX data). A site that is fast on head-office fibre but slow on a buyer's 4G phone on a job site will be rated slow.
What the audit costs, then the fixes
Price gaps come from scope: number of templates analysed, presence of a configurator, access to code and server.
| Service | Content | 2026 price (EUR, excl. VAT) | Lead time |
|---|---|---|---|
| Flash audit | 5 templates, Lighthouse + CrUX report, 15 recommendations | 1,500 to 2,000 | 5 days |
| Full audit | 10 to 15 templates, JavaScript profiling, costed priority plan | 2,500 to 4,000 | 2 weeks |
| Image optimisation | WebP/AVIF conversion, responsive sizes, lazy loading | 1,500 to 3,000 | 1 to 2 weeks |
| Configurator loading rework | Deferred import, load on click, lighter mobile version | 2,500 to 5,000 | 2 to 3 weeks |
| Third-party script clean-up | Tag manager, chat, CRM, deferred cookies | 800 to 2,000 | 1 week |
| CDN + server cache | Product page caching, Brotli compression | 500 to 2,000 | 3 to 5 days |
| 3-month monitoring | CrUX dashboard, regression alerts | 150 to 400 per month | Ongoing |
The most profitable line is almost always images: moving to WebP or AVIF cuts weight by 60% on average, with no visible loss on a desk or chair render. The trickiest is the configurator, which should load only when the buyer clicks "Customise".
Prioritise by expected return
| Action | Effort | Typical effect | Priority |
|---|---|---|---|
| WebP/AVIF images + dimensions | Low | LCP -1 to -2 s | 1 |
| Defer chat and marketing scripts | Low | INP -100 to -300 ms | 1 |
| On-demand configurator | Medium | INP under 200 ms on product pages | 2 |
| Client-side catalogue filters | Medium | Navigation 3 to 5 times smoother | 2 |
| Hosting migration | High | TTFB -300 to -600 ms | 3 |
| Full redesign | Very high | Variable | Only if the CMS blocks everything |
A redesign is justified only if the current CMS prevents these fixes. In most audits, 70 to 80% of the gain comes without changing platforms.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sarah, marketing director of an office furniture manufacturer near Rotterdam, receives 80 quote requests a month versus 105 a year earlier. Average signed fit-out project: EUR 18,000, close rate 12%. She orders a full audit (EUR 3,200) and EUR 8,500 of fixes, EUR 11,700 in total. Four months later, requests are back to 96 a month (+20%). The 16 extra quotes produce about 1.9 additional orders a month, roughly EUR 34,500 of extra monthly revenue. At a 35% gross margin, the investment is paid back in less than one month of additional production.
FAQ
How long before the effect shows in Google?
CrUX data is computed over a rolling 28 days. Allow 4 to 8 weeks after release for metrics to turn green in Search Console, then 2 to 3 months for the effect on rankings.
Do we need to rebuild the whole site to pass Core Web Vitals?
Rarely. In 70 to 80% of cases, images, third-party scripts and deferred configurator loading are enough, for EUR 4,000 to 12,000 instead of EUR 30,000 or more for a redesign.
Is a 3D configurator compatible with a good INP?
Yes, if it loads on demand rather than when the product page opens. A well-split configurator keeps INP under 200 ms on a mid-range smartphone.
Which indicators should we track after the audit?
The share of green visits for LCP, INP and CLS, the quote form conversion rate and monthly request volume. Monitoring at EUR 150 to 400 a month prevents regressions when products are added.
Does the audit cover local SEO?
The Core Web Vitals audit is technical. It can be paired with a local SEO audit (Google Business Profile, showroom pages) for an extra EUR 800 to 1,500.
