How we ranked these SEM agencies
This is not a paid directory. Each agency was assessed on the factors that decide whether an SEM engagement pays off:
- Certifications, such as Google Partner or Premier Partner status
- Proven performance with results measured in leads, sales and cost per acquisition
- Transparency in reporting and account ownership
- Full-channel capability across search, shopping, display and social
- Fit and value for different business sizes and budgets
What a good SEM agency in Singapore delivers
SEM is more than switching on Google Ads. A capable agency covers the full paid stack, aligned to one strategy:
- Search Ads to capture high-intent demand
- Google Shopping for ecommerce, via Google Ads
- Display and remarketing across the Google Display Network
- Paid social to extend reach, through social media ads
- Landing pages and CRO so clicks convert
- Tracking and transparent reporting on cost per lead and return
If an agency only runs search ads and reports on clicks, you are leaving results on the table. See our full SEM services and PPC services.

SEM pricing in Singapore: what you actually pay
SEM cost has two parts: the media budget paid to Google, and the agency management fee.
|
Business stage |
Monthly media budget |
Best starting point |
|
Small business / testing |
SGD 1,500 – 3,000 |
One channel, tight keyword focus |
|
Growth SME |
SGD 3,000 – 8,000 |
Search, Shopping and remarketing |
|
Competitive / scaling |
SGD 8,000+ |
Full-funnel, multi-channel SEM |
Management fees are quoted on top, typically from around SGD 1,000 per month depending on scope. Eligible SMEs can offset qualifying costs through the PSG grant.
PSG grant: can you subsidise SEM?
Eligible Singapore SMEs can receive up to 50% support for qualifying digital marketing solutions through the Productivity Solutions Grant, with a pre-approved vendor such as MediaPlus. It lowers the barrier to running professional paid campaigns.
How to choose the right SEM agency
- Start with your goal. Leads, sales or awareness each shape the right partner and channels.
- Set a target metric. Agree the cost per lead, ROAS or CPA you will both be measured on.
- Check certifications and proof. Google Partner status and real results from businesses like yours.
- Demand transparency. You should own your Google Ads account and see every dollar of spend.
- Confirm full-channel capability. Search, shopping, display and social should work together.
- Match scale to your size. An enterprise agency may over-serve an SME, and vice versa.
Common mistakes to avoid
- Choosing on price alone instead of results and transparency
- Letting an agency own or hide your ad account
- Judging success on clicks rather than leads and revenue
- Running search ads with no landing page or conversion tracking
- Signing long lock-in contracts with no clear exit
Frequently asked questions
How much does SEM cost in Singapore?
Most SMEs run a media budget of SGD 1,500 to SGD 8,000 per month plus a management fee. The right number depends on your industry, competition and goals, and PSG can offset part of the cost.
How long until I see results from SEM?
SEM can drive clicks and leads within days of launch, with meaningful optimisation, where cost per lead drops, usually within 4 to 8 weeks.
Can I run SEM in multiple languages in Singapore?
Yes. Agencies like OOm run bilingual English and Mandarin campaigns, which can widen reach in Singapore’s mixed-language market.
Is it better to use an agency or run SEM in-house?
An agency brings certified expertise, tools and cross-channel experience, which usually beats a small in-house team for cost efficiency, though large advertisers may run both.
Do I own my Google Ads account with an agency?
You should. Reputable agencies give you full ownership and transparency. Treat anything less as a red flag.
