Suggested Approach

Clarify that 'market size' refers to Google's addressable revenue opportunity in Southeast Asia, then break it down by product lines (Search/Ads, Cloud, Hardware, Play Store) and key countries. Use a top-down TAM/SAM/SOM framework, estimating population, internet penetration, and digital ad spend per capita, and validate with known industry benchmarks.

Pro tip: Anchor your estimate to a known figure, such as Southeast Asia's total digital ad market (~$10B in 2023), and then derive Google's share (e.g., ~30-40% for search/display) to show structured thinking and business acumen.

1. Define the market and scope

Clarify that 'market size' means Google's total addressable revenue opportunity in SEA across its major products. Specify the region (e.g., Indonesia, Thailand, Vietnam, Philippines, Malaysia, Singapore) and time frame (annual).

2. Segment by product lines

Break Google's revenue into key streams: Advertising (Search, YouTube, Display), Google Cloud, Google Play, and Hardware. Focus on advertising as the largest contributor in SEA.

3. Estimate total addressable market (TAM) per product

For advertising, estimate SEA's total digital ad spend using population, internet penetration, and average ad spend per user. For Cloud, estimate enterprise IT spend. For Play, estimate app store revenue.

4. Apply Google's market share

Use industry benchmarks to estimate Google's share in each segment (e.g., ~90% search share, ~30% digital ad share overall). Multiply TAM by share to get Google's revenue opportunity.

5. Sum and sanity-check

Add up the segment estimates to get total market size. Sanity-check against known figures (e.g., Google's reported revenue in APAC) and adjust for growth trends.

Key Points to Mention

  • Population and internet penetration rates in SEA countries (e.g., ~680M people, ~70% online)
  • Digital advertising spend in SEA (e.g., ~$10B in 2023, growing ~15% annually)
  • Google's dominant search market share (~90%+) and YouTube's popularity
  • Google Cloud's growing presence in SEA and enterprise digital transformation
  • Google Play's revenue from app sales and in-app purchases in the region
  • Potential for growth due to increasing smartphone adoption and e-commerce
