Yeti bot

The Yeti bot is the official web crawler for Naver, South Korea's leading search engine. Its purpose is to index web content for Naver's search results, with a strong emphasis on Korean-language content. For any website targeting the South Korean market, being properly indexed by Yeti is essential for gaining visibility and organic search traffic.

What is the Yeti bot?

The Yeti bot is the web crawler for Naver, South Korea's top search engine. It is the primary indexing bot for the platform, systematically visiting and analyzing web pages to include them in Naver's search results. The bot identifies itself in server logs with user-agent strings such as Yeti/1.0 (...) or, more recently, Mozilla/5.0 (...) Yeti/1.1; (...). The crawler's operations are managed through Naver's infrastructure and are focused on maintaining a comprehensive index of the web with a strong emphasis on Korean-language content.

Why is the Yeti bot crawling my site?

The Yeti bot is crawling your website to discover and index its content for Naver's search results. It is particularly interested in text content, especially pages with Korean-language material or content that is relevant to a Korean audience. The frequency of visits depends on your site's relevance to Naver's users. High-authority Korean domains will be visited more frequently. This is an authorized and legitimate activity for a major search engine.

What is the purpose of the Yeti bot?

The purpose of the Yeti bot is to support the Naver search engine by discovering and indexing web content. As South Korea's dominant search platform, Naver relies on Yeti to build and maintain its index. The data it collects powers various Naver services beyond search, including Naver Blog and Naver Cafe. For website owners, being indexed by Yeti provides significant value through visibility to Naver's large user base, which is crucial for businesses targeting the Korean market.

How do I block the Yeti bot?

To prevent the Yeti bot from accessing your website, you can add a specific disallow rule to your robots.txt file. This will prevent your pages from appearing in Naver's search results.

To block this bot, add the following lines to your robots.txt file:

User-agent: Yeti
Disallow: /

How to verify the authenticity of the user-agent operated by Naver?

Reverse IP lookup technique

To verify user-agent authenticity, you can use host linux command two times with the IP address of the requester.
  1. > host IPAddressOfRequest
    This command returns the reverse lookup hostname (e.g., 4.4.8.8.in-addr.arpa.).
  2. > host ReverseDNSFromTheOutputOfFirstRequest
If the output matches the original IP address and the domain is associated with a trusted operator (e.g., Naver), the user-agent can be considered legitimate.

IP list lookup technique

Some operators provide a public list of IP addresses used by their crawlers. This list can be cross-referenced to verify a user-agent's authenticity. However, both operators and website owners may find it challenging to maintain an up-to-date list, so use this method with caution and in conjunction with other verification techniques.
