How to Choose

• Budget fit: confirm whether fees are a fixed retainer, a percentage of ad spend or performance-based, and check the minimum monthly commitment suits your budget.
• Industry experience: ask for relevant sector examples and evidence of managing campaigns with comparable products, price points or buying cycles.
• Reporting transparency: ensure you receive regular, plain-language reports and retain ownership of your Google Ads account and data.
• Specialisation match: decide whether you need a dedicated paid-search specialist or a full-service agency covering SEO, social and web alongside SEM.
• Contract flexibility: check lock-in periods, notice terms and whether campaigns and assets remain yours if you switch providers.

Frequently Asked Questions

How much does a Google Ads / SEM agency cost in Singapore?

Costs vary by agency and scope, but management fees in Singapore commonly fall in the range of roughly SGD 800 to SGD 3,000 or more per month, sometimes charged as a percentage of ad spend (typically around 10–20%). This is separate from your actual advertising budget paid to Google. Larger or more competitive campaigns cost more. Always clarify what the fee covers, whether there is a minimum ad spend, and whether setup or reporting is billed separately.

How do I evaluate whether an SEM agency is any good?

Assess relevant experience in your industry, ask how they measure success (cost per lead, conversions, ROAS rather than just clicks), and request a sample report. Confirm you will own your Google Ads account and data, and check platform certifications such as Google Partner status. Beware of guaranteed rankings or vague promises. Speak to references where possible, and favour agencies that explain their strategy clearly and set realistic, measurable expectations for your budget.

How long does it take to see results from Google Ads?

Google Ads can generate traffic and leads within days of launch, but meaningful results usually take longer as campaigns are optimised. Most agencies expect an initial learning and testing phase of around four to eight weeks before performance stabilises, with steady improvement over three to six months as data accumulates. SEM delivers faster than SEO, which typically takes several months. Timelines depend on budget, competition and the maturity of your landing pages and tracking.
