Core Web Vitals Audit for a B2B Website in Singapore: Cost and Payback

The verdict in three sentences

A B2B website with a 4.8 s mobile LCP and a 62% bounce rate loses a large share of its quote requests before the offer even appears. A Core Web Vitals audit costs EUR 1,200 to 3,500 (about USD 1,300 to 3,800) in 2026, and fixes run EUR 3,000 to 9,000 depending on technical debt. The measurable goal is simple: LCP < 2.5 s, INP < 200 ms, CLS < 0.1, usually with +10 to 25% more form submissions after optimization.

What a serious audit includes, and what it costs

A useful audit goes beyond a PageSpeed Insights screenshot. It combines field data (CrUX report, Search Console) with lab measurements, template by template, and delivers a prioritized, costed fix plan.

The three most frequent causes on B2B distributor sites: uncompressed product images (often 60% of page weight), stacked third-party scripts (chat, marketing tags, maps) and WordPress themes shipping 1 to 2 MB of unused JavaScript.

Before / after: the numbers to aim for

These gains are not guaranteed: they depend on traffic quality and on the offer. But on B2B sites where mobile accounts for 45 to 60% of visits, the effect on inbound requests is usually visible within 4 to 8 weeks. SEO also benefits from better page experience, though it is not a decisive factor on its own.

Fix or rebuild: how to decide

If the audit prices more than EUR 9,000 of fixes on an ageing theme, a rebuild on a modern stack (Next.js, server rendering, AVIF images) often becomes more profitable: EUR 15,000 to 30,000 for a distributor site, but with technical debt reset to zero. Below that, fixing remains the better choice. In every case, require contractual metrics (p75 LCP measured over 28 days in CrUX) rather than a simple Lighthouse score.

Mini case study

Thomas, marketing manager at an industrial supplies distributor in Singapore, gets 18,000 visits a month and 200 quote requests (1.1%). His quote-to-order rate is 20%, with an average order of EUR 2,400 and a 30% gross margin.

He invests EUR 2,400 in the audit and EUR 6,000 in fixes, EUR 8,400 in total. With +15% form submissions, he gains 30 requests a month, i.e. 6 orders and EUR 14,400 of extra revenue, so EUR 4,320 of gross margin. The project pays back in about 2 months.

FAQ

What is the difference between a Lighthouse score and Core Web Vitals?

Lighthouse measures one simulated lab visit, while Core Web Vitals reflect real visits over 28 days (75th percentile). Google uses real data: a Lighthouse score of 90 can hide a field LCP of 3.5 s.

How long before results show in Search Console?

CrUX data is computed over a rolling 28 days: allow 4 to 6 weeks after release for URLs to move to "Good".

Is a EUR 1,200 audit enough?

For a brochure site under 20 pages, yes. For a distributor site with a catalogue, filters and a customer portal, a standard audit at EUR 1,800 to 2,600 avoids missing the slowest templates.

Should we remove third-party marketing tools?

Not necessarily: loading them after interaction or through a server-side tag manager often cuts INP by 100 to 200 ms without losing data.

Do the fixes last?

Without monitoring, 1 site in 2 regresses within 6 months because of new content or plugins. Monitoring at EUR 150 to 400 per month catches regressions before they cost leads.
