Most Singapore businesses don’t struggle to get SEM proposals, they struggle to compare them.

One agency quotes a “management fee + ad spend,” another pushes Performance Max with a glossy forecast, a third focuses on landing pages and tracking. All three can sound reasonable, but the business outcome you’ll get can be wildly different.

This guide shows you how to compare proposals from an SEM agency in Singapore in a way that’s fair, commercial, and grounded in Singapore’s realities: high CPCs, mobile-first behaviour, WhatsApp and calls as primary conversions, and PDPA constraints.

Step 1: Make proposals comparable by defining your “win condition”

Before you judge any agency’s strategy, force a shared definition of success. In Singapore, SEM often looks “expensive” on paper because CPCs are high in many categories (medical, legal, renovation, B2B industrial), but the correct benchmark is rarely CPC. It is profit per acquired customer.

Ask every agency to base their plan on your unit economics:

  • Gross margin (or contribution margin) per sale
  • Close rate from lead to customer (for lead gen)
  • Average order value and repeat rate (for e-commerce)
  • Capacity constraints (how many consults, tables, calls you can actually fulfil)

If you don’t have these numbers, ask the agency to help you estimate them, then put the assumptions in writing.

Here’s a simple way to standardise what “profitable” means:

Business model Core metric to compare proposals How to compute it (simple version) Common Singapore nuance
Lead generation (clinic, law firm, B2B distributor) Break-even CPA (per qualified lead or booked consult) Profit per customer × lead-to-customer close rate Many conversions happen via call or WhatsApp, not forms
E-commerce (SG + regional shipping) MER or blended CAC Total ad spend ÷ total revenue (or new-customer revenue) Cross-border traffic leakage can distort ROAS
High-ticket services Cost per booked appointment (not just lead) Spend ÷ verified booked consults Fast follow-up matters, speed-to-lead is a hidden lever

If a proposal never mentions break-even CPA, lead-to-sale assumptions, or capacity, you’re not comparing growth plans, you’re comparing platform tactics.

Step 2: Standardise scope, “SEM management” varies a lot in Singapore

Two proposals can quote the same monthly fee but include completely different work.

A practical approach is to ask for a one-page scope summary under these headings, then compare line-by-line:

Measurement and tracking (non-negotiable)

In 2026, measurement is the foundation. With privacy changes and consent requirements, Singapore advertisers should be extra disciplined with data collection, access control, and PDPA-safe processes.

A credible proposal should state:

  • What counts as a primary conversion (form, call, WhatsApp, purchase)
  • Whether GA4 and Google Tag Manager (or an equivalent setup) is included
  • How they will track calls and WhatsApp clicks
  • Whether they can import offline outcomes (qualified lead, booked, paid) back into Google Ads
  • How they handle consent and data governance in line with Singapore’s PDPA

If the proposal says “we’ll optimise for leads” but does not define what a lead is, treat the rest as marketing.

Account build, query control, and ongoing optimisation

A strong SEM agency should clarify how they will control intent and wasted spend:

  • Match type strategy and search term monitoring
  • Negative keyword process (how often, and who approves exclusions)
  • Brand vs non-brand separation (especially important for overseas entrants entering Singapore)
  • Location targeting controls (to prevent traffic leakage)

Landing pages and conversion support

In Singapore, mobile conversions dominate in many categories, and a lot of buyers want to “tap to WhatsApp.” If the agency does not address landing pages, they may still be competent, but expect weaker ROI in competitive markets.

Good proposals are explicit about:

  • Whether landing page recommendations are included, and how they’ll be implemented
  • Page speed and mobile UX checks
  • Message match (keyword intent ↔ ad copy ↔ page headline ↔ CTA)

If you want a reference checklist of what a conversion-first setup looks like, you can compare the agency’s plan against Realisma’s guide: SEM Services Singapore: Setup Checklist for Better ROAS.

Step 3: Compare targeting and localisation, not just keywords

Singapore is small, but it’s not simple.

A proposal should demonstrate they understand how Singapore search behaviour differs:

  • Hyper-local modifiers (“near me”, MRT stations, neighbourhoods)
  • Mobile-first lead behaviour (calls, WhatsApp, map taps)
  • Multilingual reality (English with Chinese terms, and industry-specific phrasing)
  • Cross-border intent (tourists, Malaysian traffic, or regional shoppers)

Ask each agency to show exactly how they’ll prevent common Singapore waste:

  • Geo leakage: People outside Singapore clicking your ads
  • Ambiguous intent: Broad queries that trigger irrelevant searches
  • Competitor and aggregator traffic: Clicks from research-mode users who never convert

A practical tell is whether the proposal includes an example of a keyword list with negatives and a location plan. Strategy without exclusions is rarely strategy.

Step 4: Understand pricing models and the incentives they create

The pricing model influences behaviour.

Pricing model What it usually optimises for When it can work well Key risk in Singapore
Flat retainer Stable workload and predictable process Most SMEs, regulated services, high-CPC lead gen If scope is vague, effort can drift downward over time
% of ad spend Scaling spend E-commerce with strong tracking and high volume Incentive to increase spend even when marginal ROI falls
Setup fee + management Build then operate When you need a clean rebuild or tracking overhaul Underinvestment in ongoing testing after the “setup”
Performance-based CPA targets Only when conversions are tightly defined and verifiable Disputes about lead quality, attribution, and sales follow-up

If you’re evaluating performance-based offers, insist on written definitions for:

  • What counts as a payable conversion (and what doesn’t)
  • The validation process (call recording, CRM notes, booking confirmations)
  • How duplicates, spam, and uncontactable leads are handled

For a deeper framework on aligning fees to real outcomes, see: SEM Services in Singapore: Pricing vs Performance.

Step 5: Demand a tracking and attribution plan that matches your sales reality

Many Singapore businesses lose money not because the ads are bad, but because they optimise the wrong “conversion.”

Examples:

  • A medical specialist optimises for generic form fills, but the real business outcome is a booked consult.
  • A law firm optimises for calls, but many calls are irrelevant, the outcome should be qualified matters.
  • An engineering components distributor optimises for brochure downloads, but the outcome should be RFQs that match your minimum order value.

A proposal should state how they’ll connect clicks to revenue, including what happens after the lead arrives.

Ask for these specifics:

  • Which conversions will be primary vs secondary in Google Ads
  • Whether Enhanced Conversions (or equivalent) will be implemented where appropriate (see Google’s reference on Enhanced conversions)
  • Whether offline conversion imports will be used (especially for long sales cycles)
  • How frequently they will review lead quality with your team

If an agency cannot describe the lead-quality feedback loop, they will likely optimise for volume, and Singapore CPCs make that an expensive mistake.

Step 6: Look for “query discipline” and governance (especially with automation)

In 2026, most proposals will include some form of automation (Smart Bidding, broad match, Performance Max). Automation is not the problem. Lack of governance is.

Ask how they will control:

  • Search term visibility and exclusions
  • Brand safety and compliance (especially for medical and legal advertising)
  • Asset and copy testing process
  • Budget allocation rules across campaigns

If you operate in a regulated space, also ask how they handle policy constraints. For example, clinics may need to align messaging to professional advertising guidance, and law firms need to be careful with claims and solicitation. A credible agency should ask about your internal approval process and build it into the workflow.

Step 7: Evaluate the conversion system beyond Google Ads

Singapore buyers often convert through conversations, not just forms.

So a strong proposal doesn’t stop at “we drive leads.” It considers:

  • Speed-to-lead (how fast your team responds)
  • Lead routing (who receives WhatsApp messages, how calls are handled)
  • Nurture and re-engagement (especially for B2B)

For some B2B companies, SEM is strongest when paired with outbound follow-up, particularly on LinkedIn. If your proposal includes pipeline-building beyond search, it may reference tools that scale personalised conversations. One example is Kakiyo’s AI for LinkedIn conversations, which is designed to handle replies, qualification, and meeting booking while keeping outreach personalised.

The point is not to buy more tools, it’s to judge whether the agency understands the full revenue path in a Singapore context.

Step 8: Compare reporting by decision value, not by dashboard aesthetics

A proposal should specify:

  • Reporting cadence (weekly pulse vs monthly deep dive)
  • What decisions the report enables (what to cut, what to scale, what to test)
  • How performance is segmented (brand vs non-brand, device, location, time of day)
  • How lead quality will be reported (not just CPL)

If you want a ready-made interview structure for this, Realisma’s Hiring a Google Ads Marketing Agency: Key Questions pairs well with proposal comparison.

Step 9: Confirm ownership, access, and handover before you sign

This is where many Singapore SMEs get locked in.

A clean proposal and contract should clearly state:

  • The Google Ads account is owned by you (your billing profile, your admin access)
  • You have access to GA4, GTM, and any call tracking system
  • What happens at termination (handover timeline, export of audiences, documentation)
  • Data handling and confidentiality, especially if customer lists are involved

If the proposal avoids these topics, ask why. You are not just buying “campaigns,” you are building a business asset.

A practical scorecard to compare SEM proposals (copy and use)

To keep comparisons objective, score each proposal from 1 to 5 in each category, then total it.

Category What good looks like Weight (suggested)
Unit economics and KPIs Break-even CPA, lead quality definition, clear success metrics 20%
Measurement plan GA4/GTM, call/WhatsApp tracking, offline imports, PDPA-safe approach 20%
Intent and query control Match strategy, negatives process, geo leakage prevention 15%
Landing page and CRO support Mobile-first UX, message match, implementation workflow 15%
Reporting and optimisation cadence Decision-grade insights, testing roadmap, clear cadence 15%
Governance and ownership Account access, approval workflow, handover terms 15%

If an agency scores highly on creative or “platform features” but weakly on measurement and governance, you’re looking at risk.

How to make the final decision in Singapore (without overcommitting)

When two agencies look close on paper, the best tie-breaker is a short, well-defined pilot with explicit success criteria.

A sensible pilot structure is:

  • 2 to 4 weeks: tracking QA, account rebuild or restructure (if needed), landing page fixes
  • 4 to 8 weeks: controlled testing, search term cleanup, conversion-rate improvements
  • End of pilot: decision based on qualified leads or revenue signals, not vanity metrics

If you want, you can also ask a third party for a “second opinion” on proposals to spot scope gaps and hidden risks. In Singapore’s high-CPC environment, avoiding one month of wasted spend often pays for the evaluation.
