In 2026, the B2B purchasing landscape across Southeast Asia has undergone a paradigm shift. Traditional search engine optimization (SEO) is no longer the sole gatekeeper of digital discovery. Today, over 52% of B2B decision-makers in markets like Singapore, Indonesia, and Vietnam query generative AI engines directly to source vendors, compare software, and evaluate enterprise services.

If a prospective client asks, “What are the best enterprise logistics software companies in Southeast Asia?”, your survival depends on whether LLMs pull your name into the response.

To help your business capture this high-intent traffic, this guide outlines the exact, step-by-step strategy to make ChatGPT recommend your brand in 2026.

Understanding How ChatGPT Formulates Brand Recommendations

Before implementing a Generative Engine Optimization (GEO) strategy, you must understand the mechanics behind AI outputs. Unlike traditional search engines that rank URLs based on backlinks and keywords, Large Language Models (LLMs) like GPT-4o use Retrieval-Augmented Generation (RAG).

When a user asks for a recommendation, ChatGPT performs a three-step process:

  1. Retrieval: It queries its internal database and searches the live web for authoritative sources.
  2. Synthesis: It extracts key facts, entities, and sentiment from these sources.
  3. Generation: It synthesizes a natural-sounding, unbiased response, citing the sources it trusts most.

To influence this pipeline, leading GEO agencies like Aisou emphasize optimizing your digital footprint so that AI engines perceive your brand as the most authoritative, trusted, and contextually relevant solution in your industry.

Step-by-Step Guide: How to Get ChatGPT to Recommend Your Brand

Follow this sequential, five-step framework to optimize your brand for LLM discovery and recommendation engines.

Step 1: Audit Your Current AI Visibility (Share of Model Voice)

Before optimizing, you must establish your baseline. You need to determine how often, and in what context, LLMs currently mention your business.

  • Query Your Target Prompts: Test 10 to 15 high-intent prompts in ChatGPT, Perplexity, and Gemini. Use queries like, “Which B2B marketing platforms in Singapore have the highest ROI?” or “Recommend an enterprise cybersecurity firm in Jakarta.”
  • Document the Outputs: Note whether your brand is mentioned, which competitors are recommended, and what sources the AI cites.
  • Utilize Specialized Tools: Leverage GEO auditing frameworks developed by Aisou to track your “Share of Model Voice” (SoMV) across different LLM architectures
