Google Search vs LinkedIn Ads: Best ROI for SG B2B

Singapore CPC Maths: Search vs LinkedIn

The Singapore B2B auction pool is small but dense with buyers. A head term like “accounting software singapore” routinely clears SGD $8–$10 CPC on Google when 2–3% of clicks convert. Long-tail variants like “Xero migration for SG corporate secretarial firms” drop to SGD $2–$4 CPC and generate far fewer wasted impressions.

LinkedIn in SG behaves differently. Sponsored Content to “Finance Director” or “Head of Technology” titles at banks and oil & gas majors runs on a CPM of SGD $28–$45. The implied CPC lands at SGD $12–$18, but the click rarely comes from a user actively comparing vendors. LinkedIn Lead Gen Forms cut CPC by roughly 30%, but those leads arrive with zero search context and need three sales touches before they commit to a discovery call.

Funnel Position: Search is a Landing Spot, LinkedIn is a Billboard

Google Search only appears when pain is already live. The procurement manager searching “why is my corporate tax filing delayed” or “best HRMS for 100 employees in Singapore” is past the awareness stage. Your ad is an answer to a specific, timestamped problem. Downstream, these leads self-qualify and push themselves into a demo slot within two weeks.

LinkedIn targets that same manager before the problem is verbalised. You pay for repeated exposure against a job title—VP Engineering at Grab HQ, Procurement Director at Keppel, CTO at a precision-engineering firm in Woodlands. This is billboard behaviour. It works, but it requires a nurture layer (HubSpot workflows or Marketo) to stay relevant over 30–60 days. Search leads move; LinkedIn leads need momentum injected.

ABM Advantage: LinkedIn’s Company List Targeting

Google Ads has no reliable job-title layer. In-market and affinity audiences are too coarse for a sales team carrying 15 target accounts in SG. LinkedIn Matched Audiences lets you upload a Salesforce report—say, 300 logistics firms under 250 employees, or 80 Singapore-registered legal tech companies—and hit exact decision-makers inside those domains.

This is the single strongest technical argument for LinkedIn in the SG market. When your deal size crosses SGD $200k, the addressable market is literally a few hundred logos. A Google query-based campaign cannot isolate “VP Ops at a specific Port of Singapore Authority contractor.” LinkedIn can. For mid-market teams, this turns into a repeatable booking engine: upload the list, run Message Ads to 500 people, get 12 qualified briefs.

Attribution Reality: GA4, GCLID, and the LinkedIn Insight Tag

Google Search wins on measurability. GA4 captures query-level search terms through GCLID, and a solid conversion action (form submission or booked meeting) gives you a clean cost-per-SQL number within 48 hours. The catch in SG: a significant share of B2B inquiries arrive by WhatsApp or a called-in, non-tracked phone line. Without a call-tracking tool like JustCall in the stack, your Google ROI report is fiction.

LinkedIn defaults to a 30-day click and 7-day view attribution window. Multi-touch conversion attribution inside LinkedIn Campaign Manager costs significantly more and still ignores the WhatsApp call 10 days later. The fix is a lead source field in HubSpot or Salesforce pegged to subscriber channel, plus a mandatory one-question qualification form (“Where did you first hear about us?”) during the first sales call. This gives you truthful, pipeline-level ROI data that no platform dashboard delivers alone.

Which Gets the SG B2B Budget: A Decision Rule

Split direction by Average Contract Value, not by brand preference.

– ACV under SGD $20k: Google Search takes 80–85% of the paid budget. The velocity matters more than the premium targeting. A seven-day close cycle beats a 60-day nurture path every time.

– ACV between SGD $50k and $120k: Run a hybrid at 40/60 Google-to-LinkedIn. LinkedIn gets first two touches for the ABM list; Google harvests the final high-intent search when the buyer acts.

– ACV above SGD $200k: LinkedIn owns the budget. At this price point, there are only 200–400 real accounts in Singapore that can buy from you. Google captures 3% of them; LinkedIn company-list targeting captures 60%.
