## Summary

ChatGPT ads generated click‑through rates (CTR) between 0.6% and 0.75% for Free and Go users in the U.S., U.K., Canada, Australia and New Zealand, while Brazil, Mexico, Japan and South Korea saw rates from 1.21% to 1.91%, according to a Graphite report that used Similarweb panel data. The report, titled “The State of ChatGPT Ads,” combines the panel with Graphite’s review of U.S. ad copy and landing pages and notes that Similarweb provides percentages, not raw counts, so individual user numbers are unavailable.

OpenAI began testing ads in the U.S. on Feb 9 and later expanded to the U.K., Mexico, Brazil, Japan and South Korea. The data cover varying periods – five to 25 weeks per market – and show that the four Asian‑American markets outperformed the English‑language markets. Advertisers such as Jotform and Resume.io dominated impression share, while B2B SaaS accounted for 19.9% of U.S. impressions and retail 10.4%. Recent moves include an Amazon Ads pilot and a Shopify partnership, expanding ChatGPT Ads to more than 60 countries.

The report highlights the lack of benchmark data for advertisers, making it harder to gauge campaign performance against these market‑level CTRs.

## Key points

- Brazil led ChatGPT ad CTR at 1.91%, followed by Mexico 1.55%, Japan 1.53%, South Korea 1.21%
- U.S., U.K., Canada, Australia and New Zealand CTRs ranged 0.6%‑0.75% for Free and Go plans
- OpenAI expanded ChatGPT Ads to over 60 countries, adding Amazon Ads pilot and Shopify partnership

## Why it matters

Marketers can compare their campaign CTRs to market‑level benchmarks and plan expansions, while the new Shopify and Amazon integrations give immediate channels to run ChatGPT ads.
