Google Ads Benchmarks in South Korea

The average CPC for Google Search Ads in South Korea is around ₩1,525 across all industries. South Korea sits in the mid-range globally — more competitive than emerging markets but below the highest-cost English-speaking markets. Legal, financial services and insurance verticals see the highest CPCs, while food, entertainment and arts categories tend to be significantly cheaper.

A good CTR for Google Search Ads in South Korea is typically 2.8–4.5%, with a cross-industry average around 3.0–3.3%. CTR varies significantly by industry — always compare against the benchmark for your specific vertical. Display campaigns will have much lower CTRs (typically under 0.5%), so always compare like for like.

South Korea sits in the mid-range of global Google Ads costs. CPCs are lower than the USA, UK, or Australia, but higher than most emerging markets. The local auction is shaped by domestic advertiser competition, consumer purchasing power, and the reach of international advertisers targeting Asia Pacific. Local-currency CPCs can look high nominally but translate to reasonable USD costs.

The average Google Ads conversion rate in South Korea is approximately 3.7–4.2% across all industries. Service businesses with clear calls-to-action (legal, education, home services) often see higher rates. eCommerce categories typically see lower conversion rates due to longer decision cycles. Always ensure you're tracking all relevant conversion actions — phone calls, form submissions and chat enquiries alongside purchases.

Always plan and report in local currency (KRW) when advertising in South Korea. Google Ads charges in the currency of the account's billing country — if your account is set to KRW, all costs and benchmarks should be tracked in KRW. Using USD benchmarks for South Korea campaigns will give you misleading comparisons because exchange rates and local purchasing power differ significantly.
