Singapore's SEO market has split into two conversations that used to be one. Classic ranking work — technical health, content, links, local and international SEO — still decides most of a brand's organic revenue. But a second layer has shown up alongside it: answer engine optimisation (AEO) and generative engine optimisation (GEO), the practice of getting cited inside ChatGPT, Perplexity and Google AI Overviews rather than just ranked on a results page.
The agencies below were shortlisted because they can show verifiable capability across both layers — not because they bought a spot on a list. We checked each agency's own site, named leadership, service pages, case studies and (where available) independent signals such as LinkedIn headcount, before writing a word of this profile. Where a claim couldn't be verified — an award, a client, a ranking — we left it out rather than repeat it. See our Methodology for how we build and verify lists like this one, or learn more about MarTech Wise.
The 10 agencies below are presented alphabetically, not ranked by preference. Fit depends on your industry, budget and whether you need SEO alone or SEO bundled with paid media, content, web development or AI-search optimisation.

Pricing isn't in this table because none of these agencies publish standardised rate cards — Singapore SEO retainers are quoted against scope, so treat any fixed number you see elsewhere with caution. See Pricing factors below for what actually moves the price.
Selection criteria
We included an agency only if we could verify, from its own site or credible public sources, that it:
- Actively delivers SEO (not just paid media or web design with SEO as an afterthought) for Singapore-based or Singapore-serving clients.
- Names real services, and where possible real clients or case studies, rather than only generic marketing copy.
- Shows some capability, or a clear roadmap, for AI-search visibility (AEO/GEO) alongside classic search — because Singapore buyers are now asking for both.
- Has a locatable Singapore presence (registered address, HQ or clearly stated Singapore operations).
We did not weight inclusion by advertising spend, award count alone, or agency size. Two of the smallest teams on this list (Best SEO, Webscelerate) are included because their evidence held up, not because of scale.
The 10 agencies
1. Best SEO
- Location: 12 Woodlands Square, Woods Square Tower 1, Singapore
- Founded: 2019, by founder Jim Ng; operates under Best Marketing Agency
- Team size: 9 full-time specialists (per its own About page)
- Key services: Technical SEO audits, keyword research, link building, content strategy, on-page and local SEO, e-commerce SEO, AI-augmented SEO workflows, GEO/AEO, revenue attribution
- Industries served: 43 industries spanning SMEs, e-commerce and local services
- Proof: States 146+ clients, 2,000+ page-one rankings and S$33M+ in tracked client revenue; also runs its own e-commerce business (Singapore Florist) as a live SEO test bed
Why it made the list: Best SEO is one of the few agencies on this list that publishes a specific, checkable revenue-attribution claim rather than a generic "we grow your traffic" pitch, and it tests its own methods on a business it owns. That's a useful trust signal for SMEs who want proof before signing a retainer.
Consider: A nine-person team means less bandwidth for large, multi-market accounts — better suited to a single-market SME engagement than an enterprise rollout.
2. Digitrio
- Location: 22 Cross Street, #02-01, Singapore
- Founded: 2014
- Team size: Not publicly disclosed
- Key services: SEO, GEO, local SEO, SEO consulting, SEO copywriting, content marketing, SEM, display and Facebook advertising, web design and development, website audits
- Industries served: Education, hospitality, healthcare and veterinary, logistics, professional services, consumer products, and B2B/B2C SMEs
- Proof: Named clients include Sol X, Termite Specialist, Magellan X, The Perse Singapore, Repton International School Malaysia, Heritage Collection, VES Hospital, Aventis Graduate School and Novita
Why it made the list: Digitrio positions explicitly against "ranking-only" SEO, built around transparency, data analysis and qualified traffic rather than vanity keyword positions — a stance worth testing if you've been burned by a rank-report-only agency before.
Consider: Leadership names, exact headcount and a LinkedIn company profile weren't confidently verifiable at the time of research — worth asking about team structure directly during a pitch.
3. First Page Digital
- Location: 120 Robinson Road, #05-01, Singapore; part of a group with entities across Australia, Hong Kong, New Zealand, the United States, Austria and Germany
- Founded: 2011
- Team size: Large Singapore team; group reports 900+ global talent
- Leadership: Shane Liuw (CEO), Nick Bell (Managing Director), Fei Bell (Head of Operations), Eugen Kim (CMO), Fabian Seow (Technical Director), Abel Chan (Head of Content)
- Key services: Local, international and enterprise SEO; AI SEO, GEO and AEO; e-commerce SEO; Google Ads; paid social; programmatic advertising; reputation management; CRO; iGaming marketing; content; web development
- Industries served: Cross-industry, from startups to Fortune 500, plus e-commerce, enterprise, technology and iGaming
- Proof: States 6,000+ clients globally across its 9-company, 11-country group
Why it made the list: If you need SEO to sit alongside paid media, CRO and reputation management under one roof — with the operational scale of a multi-country group — First Page Digital is one of the few Singapore-headquartered options built for that scope.
Consider: Note this is a different entity from the unrelated agency that previously used a similar name in Singapore; confirm you're briefing firstpagedigital.sg specifically.
4. Heroes of Digital
- Location: Singapore, with operations extending to Malaysia
- Founded: 2015
- Team size: 100+ specialists (per its own site)
- Leadership: Shane Yuen (CEO & Founder), Roy Chen (Director of Operations), Rachel Lin (Account Director), Boston Toh (Director of Sales), Arash Nouzari (Director of SEO), Jening Ch'ng (Head of Tech)
- Key services: SEO, AI SEO and "SEO for ChatGPT," e-commerce and enterprise SEO, Google Ads, Meta and TikTok Ads, conversion landing pages, website design, CRO, analytics and attribution, its proprietary HeroIQ revenue-tracking platform
- Industries served: Education, healthcare, retail, professional services, F&B, automotive, travel and leisure, e-commerce
- Proof: States 1,000+ businesses served and 120,000+ qualified leads since 2015. Named clients include NTUC FairPrice, Louis Vuitton, Kaplan, NUS-ISS, My First Skool, Scanteak and StarDream Cruises
Why it made the list: Heroes of Digital is one of the more explicit "SEO for AI search" positioned agencies in this list, and it backs that with a named attribution product (HeroIQ) rather than a vague promise of "data-driven" reporting.
Consider: A 100+ person team and enterprise client roster suggest retainers sized for mid-market and larger budgets rather than micro-SME spend.
5. IMPACT!
- Location: 195 Pearl's Hill Terrace, #02-12, Singapore
- Founded: 2012, by founder and Managing Director Donald Chan
- Team size: Approximately 15
- Key services: SEO, digital strategy, B2B and technology marketing, content marketing, web design and development, paid media, social and LinkedIn marketing, video and podcast marketing, branding, ABM, demand generation, MarTech consulting, PR, employer branding, marketing automation and HubSpot delivery
- Industries served: Technology, cybersecurity, SaaS, B2B, financial services and fintech, healthcare, education, ESG/sustainability, AI and robotics
- Proof: Named clients include Microsoft, Sophos, OCBC, ST Engineering, National Healthcare Group, Certis, Citrix, Kuehne+Nagel and Mastercard
Why it made the list: IMPACT! is a fit for organisations that want SEO built into a wider B2B content and demand-generation programme rather than bought as a standalone service — its client roster skews toward regulated and technical sectors where that integration matters.
Consider: At roughly 15 people, IMPACT! runs leaner than the enterprise-scale agencies on this list; it suits a focused B2B/tech engagement rather than a broad multi-channel consumer campaign.
6. Impossible Marketing
- Location: 14A Yan Kit Road, Levels 2 & 3, Singapore
- Founded: 2012
- Team size: 30+ roles shown on its official team page
- Leadership: Alan Koh (Chief Marketing Officer & Head of AI), with additional CEO, Head of Growth & AI Lead, Head of Search and Chief of Staff roles named
- Key services: AI SEO, SEO, AI marketing, paid advertising, SEM, lead generation, social media marketing, web design, digital strategy, performance marketing, marketing training
- Industries served: Cross-industry — jewellery, retail, real estate, attractions, telecommunications, SMEs, non-profits and enterprises
- Proof: States 2,000+ brands served and 700+ positive reviews. Named clients include SK Jewellery, Suntec City, Singtel and Changi Airport
Why it made the list: Impossible Marketing is a genuinely home-grown Singapore agency (established 2012, work delivered in-house) with a public track record of Google and Meta partnerships and one of the larger stated client counts in this list.
Consider: Exact current headcount and its LinkedIn company profile weren't confidently verified — ask for current team structure and account-lead continuity before signing.
7. OOm
- Location: Singapore HQ, with operations in Quezon City (Philippines), Hong Kong SAR and Shenzhen (China)
- Founded: 2006
- Team size: 51–200 employees (LinkedIn)
- Leadership: Ian Cheow (CEO & Co-Founder), Wyvan Xu (COO & Co-Founder), Melvin Fam (Head of SEO), Cherie Tan (Head of Performance Marketing)
- Key services: SEO, generative engine optimisation (GEO), SEM/Google Ads, paid social, social media management, content marketing, creative, web and e-commerce development, China-focused digital marketing, lead generation
- Industries served: 100+ industries including finance, healthcare, e-commerce, B2B, technology, legal and education
- Proof: States 8,000+ clients across 100+ industries and 30+ awards; is a Premier Google Partner and Meta Business Partner. Named clients include Harvey Norman, Rentokil and Nova Eye Centre
Why it made the list: OOm has the longest continuous track record on this list (founded 2006) and is one of the only agencies here with an operating presence in China — relevant if your SEO strategy needs to extend into that market.
Consider: Regional scale can mean less founder-level involvement on any single account; clarify who your day-to-day team will actually be.
8. Roots Digital
- Location: 1 Gateway Drive, #07-01 Westgate Tower, Singapore
- Founded: Not publicly disclosed (no single unambiguous founding year stated on its site)
- Team size: Boutique; exact headcount not publicly disclosed
- Leadership: Amenda Tan (Founder), Ian Ong (Chief Marketing Officer)
- Key services: SEO (including SaaS SEO, AI SEO, enterprise and international SEO, local SEO, link building, SEO content, e-commerce SEO), Google Ads, SEM, social and YouTube advertising, programmatic advertising, CRO, web design and maintenance
- Industries served: Higher education, healthcare and dental, e-commerce, interior design, legal, real estate, F&B, SaaS
- Proof: Publicly displayed clients include Orita Sinclair School of Design & Music, Yojee, SPTel and Helpling; positions as a Google Partner agency
Why it made the list: Roots Digital's named vertical depth in healthcare, education and SaaS is unusually specific for a boutique shop — useful if you're in one of those sectors and want an agency that already speaks the category.
Consider: Founding year and team size aren't disclosed, and it's a smaller operation — ask directly about capacity if you need multi-market or high-volume output.
9. Tomo Digital
- Location: Headquartered in Singapore, with delivery teams in Malaysia, Vietnam and Indonesia
- Founded: Not publicly disclosed; site states more than 10 years of search-marketing experience
- Team size: Regional team; exact current headcount not publicly disclosed
- Key services: SEO, SEM and Google Ads, international SEO, local SEO, enterprise SEO, content marketing, GEO/AI search optimisation, technical, on-page and off-page SEO, backlink building
- Industries served: Professional and consumer services, interior design, healthcare and aesthetics, education, immigration, moving and logistics, F&B and events, career coaching, e-commerce
- Proof: Named clients include Shalom Movers, EZBBQ, The Immigration People, The Butter Studio, e2i Singapore, Nanyang Executive Education and Caring Skin
Why it made the list: Tomo Digital's Southeast Asia delivery footprint (Singapore, Malaysia, Vietnam, Indonesia) is a genuine differentiator for local service businesses that also operate, or want to expand, across the region.
Consider: Founder and leadership names aren't disclosed publicly — request named point-of-contact and reporting structure before committing.
10. Webscelerate
- Location: Singapore-based, senior-led (per its own site)
- Founded: 2022
- Team size: Small, senior-led team
- Key services: Webflow design and development, marketer-owned Webflow platforms built on its Core Kit™ component system, websites structured for AI search (ChatGPT, Perplexity, Google AI Overviews) as well as classic SEO, optional SpeedCare™ post-launch retainers
- Industries served: B2B and technology, fintech, health tech, SaaS, EV/mobility, manufacturing
- Proof: Case studies cited on its site include an Ennovi corporate site built in six weeks, a PowerCred messaging and site rebuild, and an Interplex SEO-led refresh
Note on scope: Webscelerate is a Webflow build and website-optimisation specialist, not a full-service SEO agency — it's included here specifically because it builds sites structured for AI-search visibility (GEO/AEO) from the ground up, which is increasingly a prerequisite for SEO to work at all. If you need ongoing SEO strategy and execution rather than a website rebuild, pair it with, or choose instead, one of the SEO-first agencies above.
Consider: As a newer agency (2022) with a small team, it suits a defined web-build project or a marketer-owned Webflow migration more than an open-ended SEO retainer.
How to choose between them
Match the agency to the job, not the other way round:
- You need SEO bundled with paid media, content and demand generation: First Page Digital, IMPACT! or OOm are built for a multi-channel programme rather than SEO in isolation.
- You want a specialist, SEO-only engagement: Best SEO, Digitrio, Roots Digital or Tomo Digital run leaner, SEO-first offers.
- You're in a regulated or technical B2B sector: IMPACT!'s client base in fintech, healthcare and technology suggests it's used to that compliance and messaging context.
- You need regional reach beyond Singapore: First Page Digital (Australia, Hong Kong, New Zealand, US, Europe), OOm (Philippines, Hong Kong, China) or Tomo Digital (Malaysia, Vietnam, Indonesia) already operate where you might be expanding.
- Your website itself needs rebuilding for AI search before SEO can work: start with Webscelerate, then layer in ongoing SEO from one of the specialists above.
Whichever shortlist you build, ask every agency for the same three things: a named point of contact (not just a sales lead), a sample report format, and how they measure success beyond keyword position. If your need extends beyond SEO, our B2B marketing agencies in Singapore shortlist covers a wider set of channels, and if you're evaluating SEO tools rather than agencies, see 10 Best SEO Tools and Software for 2027 and Semrush vs Ahrefs: Which SEO Tool Is Better in 2027?.
SEO vs AEO/GEO: what's the difference, and do you need both?
Classic SEO earns visibility in search engine results pages through technical health, content relevance and authority signals such as links. AEO (answer engine optimisation) and GEO (generative engine optimisation) are the newer disciplines of earning citations inside AI-generated answers — ChatGPT, Perplexity, Google's AI Overviews — where there's no "page 1" to rank on, only a mention or omission.
The two aren't separate budgets in practice: the technical foundations (structured content, clear entity signals, crawlable pages) that support classic SEO also support AI-search citation. That's why most agencies on this list now describe their SEO work as covering both, rather than selling GEO as a separate line item. If an agency can't explain, concretely, how its SEO process feeds AI-search visibility, that's a fair question to press on during a pitch.
Pricing factors
None of the agencies on this list publish a standard rate card — Singapore SEO retainers are scoped and quoted individually, so we're not going to invent an "average price" figure here. What actually moves the number, based on how these agencies describe their own offers:
- Scope: technical SEO alone costs less than SEO bundled with content production, link building and paid media.
- Team seniority: agencies with named strategists, technical leads and dedicated account managers (rather than a single generalist) typically price higher.
- Industry complexity: regulated sectors (finance, healthcare) or technical B2B products usually need more research and compliance-aware content, which affects scope and cost.
- Contract length: SEO compounds over months, not weeks — most of these agencies structure work as ongoing retainers rather than one-off projects, and short-term engagements are usually priced at a premium per month.
- Market coverage: a single-market Singapore engagement costs less to run than a multi-country programme through an agency like First Page Digital, OOm or Tomo Digital.
Ask each shortlisted agency for a scoped quote against the same brief so you're comparing like with like, rather than comparing headline day-rates.
FAQs
What's the difference between an SEO agency and an SEO company in Singapore? In practice, "SEO agency" and "SEO company" are used interchangeably in Singapore's market — neither term implies a different service model. What matters more is whether the business is a specialist SEO shop (like Best SEO or Digitrio) or a full-service agency where SEO is one of several channels (like First Page Digital or OOm).
How do I evaluate a "best SEO company in Singapore" claim? Ask for verifiable proof: named clients you can check, a specific methodology, and a way to measure results beyond keyword rankings (traffic, leads, revenue attribution). Be cautious of agencies that lead with awards or "best of" badges without naming the awarding body or the criteria.
Do I need a dedicated AEO agency in Singapore, or does my SEO agency cover it? Most Singapore SEO agencies now build AI-search visibility into their standard SEO process rather than selling it as a separate AEO service — several on this list (First Page Digital, Heroes of Digital, OOm, Digitrio, Tomo Digital) explicitly mention GEO or AI SEO in their service lists. A separate, dedicated "AEO agency" is less common in this market; ask your SEO agency directly how their process addresses AI-search citation.
What does a GEO agency in Singapore actually do differently from a normal SEO agency? Generative engine optimisation focuses on structuring content and entity signals so that AI systems can accurately extract and cite your business, rather than optimising primarily for a search-results ranking. In this market, it's typically delivered as an extension of SEO work rather than a fully separate discipline — Webscelerate is the one agency on this list built specifically around AI-search-structured website builds.
How long does SEO take to show results in Singapore? None of the agencies profiled here publish a guaranteed timeline, and any agency that promises fast, fixed-timeline rankings is worth questioning. SEO typically compounds over several months; ask each agency what their own reporting shows at 3, 6 and 12 months for comparable clients.
Can a small business afford an SEO agency in Singapore? Yes — several agencies on this list, including Best SEO (9-person team) and Roots Digital (boutique), are structured for SME budgets and single-market scope, versus the larger multi-service agencies built for enterprise programmes.
Conclusion
The strongest Singapore SEO agencies in 2027 are the ones that can show their SEO work already accounts for AI-search citation, not just search-results ranking — and that can back their positioning with named clients, named leadership and a specific process rather than generic promises. Use the comparison table and "how to choose" section above to build a shortlist of two or three agencies that match your sector and budget, then request a scoped quote against the same brief from each so you're comparing fairly.
