The verdict in three sentences
A technical and SEO redesign of a B2B site in Singapore costs SGD 20,000 to SGD 55,000 in 2026 and ships in 6 to 12 weeks. The number-one risk is not the design but the migration: without a 301 redirect plan and preserved internal linking, you can lose 30 to 60 % of traffic overnight. Done right, the redesign instead targets +40 to +70 % organic traffic in 6 months thanks to green Core Web Vitals.
2026 pricing for a redesign + SEO
A B2B redesign has two distinct budgets that must be planned together: the technical rebuild (speed, structure, mobile) and the SEO work (redirects, content, internal linking). Here are the 2026 orders of magnitude in Singapore.
| Line item | Scope | 2026 range (SGD) | Timeline |
|---|---|---|---|
| Technical & SEO audit | Crawl + Core Web Vitals + backlinks | 2,000 - 5,000 | 1 week |
| Technical redesign | Fast front + structure + mobile | 10,000 - 25,000 | 3-6 weeks |
| 301 redirect plan | 300 mapped URLs | 2,500 - 6,000 | 1-2 weeks |
| Content & link migration | Preserve internal links | 4,000 - 10,000 | 2-3 weeks |
| Core Web Vitals tuning | LCP/INP/CLS in the green | 2,500 - 7,000 | 1-2 weeks |
| SEO retainer | Monthly post-launch | 600 - 1,800 /month | ongoing |
A "standard" redesign sits around SGD 25,000 to SGD 35,000; a heavier site (catalogue, multilingual, large URL history) reaches SGD 45,000 to SGD 55,000.
Zero-loss migration checklist
Post-migration traffic drops almost always come from avoidable oversights. This checklist protects your rankings on switchover day.
| Step | Key action | Impact if skipped |
|---|---|---|
| URL mapping | List the 300 URLs and their traffic | Missing redirects = 404s |
| 301 redirects | 1 old URL = 1 relevant new one | -30 to -60 % traffic |
| Internal linking | Keep links and key anchors | Lost SEO "juice" |
| Tags & metas | Reuse top-performing title/meta/H1 | CTR drop |
| Sitemap & robots | Submit new sitemap, check robots | Delayed indexing |
| Core Web Vitals | LCP < 2.5 s, INP < 200 ms, CLS < 0.1 | Mobile penalty |
| Post-live monitoring | Track 404s, rankings, logs for 4 weeks | Undetected errors |
Golden rule: freeze the URL map and redirect plan before go-live, never after. Close monitoring of 404s and rankings for 4 weeks catches 90 % of incidents before they cost traffic.
Mini case study
Mr Tan runs a B2B industrial-equipment SME in Singapore. His old site generates 1,800 organic visits per month but loads in 6 seconds on mobile and never had a redirect plan. He invests SGD 32,000 in a technical + SEO redesign with a controlled migration of 300 URLs.
Six months after launch, Core Web Vitals are green, load time drops to 1.9 s and organic traffic reaches 2,900 visits/month, a +61 % gain. At a 2.5 % enquiry conversion rate, that is roughly 27 extra qualified enquiries per month. With an SEO retainer at SGD 1,200/month, the redesign pays back in a handful of signed deals.

FAQ
Will I lose my rankings during the redesign?
Not if the migration is prepared: a full 301 redirect plan and preserved internal linking prevent the drop. A temporary dip of a few days is normal, followed by recovery within 4 to 8 weeks.
How many URLs need redirecting?
All those that receive traffic or links, often 200 to 400 for a B2B site. Each old URL points to the most relevant new page, not to the homepage by default.
What does turning Core Web Vitals green actually deliver?
A site under 2.5 s LCP improves mobile experience and ranking. On a typical B2B site, it contributes 10 to 20 % of the traffic gain seen over 6 months.
How long until +40 to +70 % traffic?
Budget 6 months: the technical effect is fast, but authority and content build gradually. First gains appear as early as weeks 6 to 8 post-migration.
Is the SEO retainer mandatory?
Not mandatory but strongly recommended: without monitoring, 404s and regressions go unnoticed. Budget SGD 600 to SGD 1,800/month depending on editorial ambition.
