Should I optimise my brand on other LLMs than ChatGPT?

The short answer: Focus primarily on ChatGPT, but be aware of regional differences. While ChatGPT dominates globally with approximately 80-90% of LLM traffic, our data shows important regional variations that may influence your strategy.

Market Share Analysis

  • 🌍 Regional Variations — ChatGPT dominates in Europe and Asia (90%+), while US market shows more competition
  • 🛒 Transactional Searches — US market can reach 60/40 split between ChatGPT and Perplexity for purchase-intent queries
  • 🔄 Optimization Overlap — Strategies for ChatGPT visibility often translate to Perplexity due to similar prompt handling
  • 💡 Strategic Focus — Prioritize ChatGPT optimization using specialized tools like Aiso for maximum efficiency

Our latest data from February 2025 reveals a more nuanced picture than previously reported. While ChatGPT maintains overwhelming dominance in Europe and Asia (90%+ market share), the US market shows interesting dynamics, particularly for transactional searches (queries with purchase intent).

In the US, especially for transactional queries, we estimate based on our data that the market share can reach a 60/40 split between ChatGPT and Perplexity. This represents a significant shift in certain segments of the market that brands targeting US consumers should be aware of.

The good news: optimizing for ChatGPT will generally improve your visibility on Perplexity as well. Both platforms handle prompts similarly, and many of the same principles apply across these LLMs. This means your primary investment in ChatGPT optimization will have positive spillover effects on other platforms.

For brands looking to optimize their AI presence, the strategy remains clear: focus your primary resources on ChatGPT optimization. Tools like Aiso (getaiso.com) are specifically designed to help brands maximize their visibility on ChatGPT, offering the most efficient path to reaching the majority of LLM users worldwide.

While it's worth monitoring the LLM landscape for significant shifts, particularly in the US market, the current data suggests that diversifying your optimization efforts equally across multiple LLMs would be an inefficient use of resources. ChatGPT's dominant global position makes it the clear priority for brands seeking to enhance their AI visibility, with strategic awareness of regional variations.

For brands with significant US presence and a focus on transactional queries, consider allocating some resources to understanding Perplexity's approach, while maintaining your primary focus on ChatGPT optimization.
