Singapore is a regional headquarters city for many companies selling across Asia Pacific. A B2B buyer here may be choosing a vendor for teams in Kuala Lumpur, Jakarta, Manila and Sydney, so they compare suppliers from several countries before building a shortlist.
That research increasingly starts in AI tools. Buyers see Google AI Overviews on their searches, or ask ChatGPT, Perplexity or Gemini which vendors to consider. Those answers favor companies whose pages are easy to crawl, clear about what they do, and mentioned by credible third parties.
This list covers five agencies that offer SEO and AI search work to Singapore companies. Four have Singapore offices. Lemniscate Growth does not; its team is based in Hyderabad.
Disclosure: this list is published by Lemniscate Growth, which is included. The other four firms were checked on their own websites. Last checked: September 2026.
How we chose
- The firm is a real, currently operating agency with a working website.
- It lists SEO on its own site, and names GEO, AEO or AI search work.
- It publishes a Singapore office address (Lemniscate is the exception, as noted above).
- Its site gives enough detail on services, industries or approach to judge fit.
- Together, the five cover different needs, from B2B pipeline programs to multichannel performance marketing.
Inclusion is based on what each firm publishes on its own site. Firms after Lemniscate appear in no particular order, and we do not repeat ratings, awards or results claims.
1. Lemniscate Growth
Lemniscate Growth is a B2B revenue pipeline generation agency, with AEO, GEO and SEO as a core service. It is registered in the US and Dubai, and its team is based in Hyderabad. It works with 35+ active clients and builds programs aimed at up to $10M in pipeline per client.
Best for: B2B technology, fintech and IT services companies with a Singapore or APAC headquarters that sell into several markets and want search measured by pipeline.
Services: Answer engine optimization (AEO), generative engine optimization (GEO), technical and content SEO, and pipeline generation work across the funnel.
Why it made the list: This is our own firm, so read this entry with that in mind. For CipherBC, a Dubai crypto infrastructure company, the program led with organic and AI search (CipherBC case study). For HiddenBrains, SEO and content grew monthly users from 50K to 600K in 11 months (HiddenBrains case study). If you need an in-person Singapore team, paid social or consumer campaigns, one of the Singapore-based firms below is likely a better fit.
2. OOm
OOm lists its Singapore office at 1 Grange Road in Orchard, plus a second office in Quezon City, Philippines. It describes itself as an "agentic search agency" and pairs SEO with GEO, which it says covers visibility across Google Search, AI Overviews, ChatGPT, Gemini and Perplexity. It also promotes its own SEOCloud dashboard, which it says includes GEO analysis.
Best for: Companies that want SEO, GEO and paid search from one Singapore team, including those targeting several countries through international SEO.
Services: SEO, GEO, international SEO, Google Ads and SEM, Performance Max and Shopping campaigns, social media and LinkedIn Ads, content marketing, website design and development, WeChat marketing and programmatic advertising.
Why it made the list: It names AI search platforms directly in its service description and offers international SEO, which suits APAC headquarters teams. WeChat marketing may help if Chinese-speaking audiences matter to you. Ask how its dashboard reports AI visibility and whether you keep the data if you leave.
3. MediaOne
MediaOne lists its Singapore headquarters at 1 Neil Road. Its SEO offer spans local, international, enterprise and e-commerce SEO, and it lists a GEO and AIO service that checks visibility on platforms such as ChatGPT and Google AI Overviews. It says a proprietary platform, Digimetrics.ai, supports its work.
Best for: Mid-size and larger organizations in sectors it lists, such as technology, business services, finance, healthcare and government, that want many channels under one agency.
Services: SEO, GEO and AIO, SEM and Google Ads, social media marketing, website design and development, branding and online reputation management, content marketing and copywriting, email marketing and press release distribution.

Why it made the list: Its lead-focused positioning and conversion work suit teams that care about what happens after the click, and it names GEO directly. Ask how it separates lead quality from lead volume in reporting, and how it attributes results between SEO and paid media.

How to choose an AEO, GEO and SEO agency in Singapore
Plan for regional buyers, not one city
A Singapore regional headquarters often buys for several markets at once. Decide early which countries matter, and ask each agency to benchmark Google results and AI answers in those countries, not only in Singapore. Our guide on how to benchmark AI visibility shows one way to set that baseline.
Treat AI answers as a shortlist channel
Google says there are no extra requirements to appear in AI Overviews or AI Mode, and that pages must be indexed and eligible to show with a snippet. Technical SEO, clear service pages and accurate structured data still come first. Our AEO and GEO playbook covers that on-site work in detail.
When a buyer asks ChatGPT, Perplexity or Gemini to compare vendors across ASEAN, the answer can draw on third-party pages as well as your own site. Ask agencies how they earn mentions in industry publications, directories and comparison pages in your target markets.
Choose languages by demand
Singapore has four official languages: English, Mandarin, Malay and Tamil. Most B2B vendor research happens in English. Mandarin content can matter for Chinese-speaking decision makers, and Malay content can help if Malaysia is a target market, so check search demand in your category before you translate.
Account for the PDPA
The Personal Data Protection Act 2012 governs how organizations collect, use and disclose personal data, and the Personal Data Protection Commission administers and enforces it, according to PDPC guidance. The Act also covers the Do Not Call registry. Ask any agency running forms, retargeting or outreach how it handles consent and those rules.
Know how public sector buying works
If you sell to government, Singapore agencies publish procurement opportunities on GeBIZ, where suppliers can search and bid. Search work does not replace that process, but clear, citable pages help evaluators who research vendors around a tender.
For more on the local market, see our Singapore AEO, GEO and SEO page. If you are comparing regional hubs, our Dubai list and India list cover other options.
Questions to ask on the first call
- Which countries and languages will you benchmark for us, and why those?
- How do you track our visibility in Google AI Overviews, ChatGPT, Perplexity and Gemini, and how often will we see it?
- Who will work on our account, and where are they based?
- How will you connect search activity to leads and pipeline in our CRM?
- How do you handle consent, tracking and Do Not Call obligations under the PDPA?
- What will you need from our subject matter experts each month to publish accurate content?
- If we use your proprietary dashboard, what data do we keep if we end the engagement?
- What will the first 90 days deliver, and how will we know if it is not working?
Red flags
- Guarantees of first-page rankings or of being named in AI answers.
- A GEO or AEO offer with no clear method for measuring AI visibility.
- Reporting on Singapore rankings only when you sell across several markets.
- Translated pages produced without checking search demand in each language.
- Dashboards or accounts you lose access to if you leave.
- Vague answers on PDPA consent and on who can access your analytics and CRM data.
