The verdict in three sentences
When your Core Web Vitals are in the red, Google caps your visibility and B2B prospects bounce before the form. In Singapore, budget USD 1,200 to 3,000 for a serious audit and USD 3,500 to 9,000 for remediation, with a clear target: LCP < 2.5 s, INP < 200 ms, CLS < 0.1. The work takes 3 to 6 weeks and lifts both SEO and conversion rate.
What the audit and remediation cover
The audit finds the bottlenecks; remediation fixes them by impact priority. 2026 order-of-magnitude estimate for Singapore:
| Service | Scope | Cost | Timeline |
|---|---|---|---|
| Performance audit | CWV analysis, waterfall, prioritised report | USD 1,200 - 3,000 | 3-5 days |
| Image optimisation | WebP/AVIF, lazy load, dimensions | USD 900 - 2,000 | 1 week |
| Code splitting + JS | Bundle, hydration, tree-shaking | USD 1,800 - 4,000 | 1-2 weeks |
| Cache & CDN | Edge cache, headers, preconnect | USD 800 - 1,800 | 3-5 days |
| Fonts & CLS | Font-display, space reservation | USD 500 - 1,000 | 2-3 days |
The right order is always: measure, fix LCP and INP first, then stabilise CLS.
Measured impact on SEO and conversion
Improving CWV is not cosmetic: it is a direct lever for traffic and leads.
| Metric | Before | After remediation | Effect |
|---|---|---|---|
| LCP | 4.1 s | 2.1 s | -49 % |
| INP | 380 ms | 150 ms | -61 % |
| CLS | 0.28 | 0.05 | -82 % |
| Mobile bounce rate | 58 % | 43 % | -15 pts |
| Pages/session | 2.1 | 3.0 | +43 % |
| Form leads (3 months) | base 100 | 122-140 | +22 to +40 % |
On a B2B site, each second of LCP saved typically converts to 5 to 8 % more conversions.
Mini case study
Wei, digital lead at a B2B services SME in Singapore, sees SEO stall despite good content: LCP 4.1 s, INP 380 ms. She commissions an audit (USD 2,000) then targeted remediation (USD 6,000), i.e. USD 8,000 over 5 weeks. 3-month result: LCP 2.1 s, +31 % form leads (from 45 to 59/month). With a qualified lead valued at USD 250 margin, monthly gain is USD 3,500. Payback in under 3 months.

FAQ
Is an audit enough or do I need a rebuild?
In 70 % of cases, audit + targeted remediation is enough; a full rebuild is only needed if the technical base (theme, framework) is beyond repair. The audit settles this objectively.
How long before Google reflects the gains?
Field CWV (CrUX) update over a 28-day window; expect 4 to 8 weeks to see ranking effect, faster on conversion.
Is INP really critical in 2026?
Yes, INP replaced FID as the interactivity metric. An INP > 200 ms penalises experience and SEO, especially on JavaScript-heavy B2B sites.
Can I measure it myself before paying?
Yes: PageSpeed Insights and Search Console give a first read. But a professional audit finds root causes and prioritises by ROI, which free tools do not.
Are the gains durable?
Yes if you set a performance budget and monitoring. Without it, the site can degrade with every feature or marketing tag added.
