YandexPartner bot

The YandexPartner bot is associated with Yandex's partnership framework, not a standalone crawler. Traffic from this bot is not from a single entity but represents a variety of business and technical integrations with Yandex. This traffic is often related to ad verification or content syndication by Yandex's partners and typically uses the main YandexBot user-agent.

What is the YandexPartner bot?

The YandexPartner bot is not a standalone web crawler but a representation of the business and technical integrations within Yandex's partnership framework. There is no dedicated 'YandexPartner' user-agent; instead, partner integrations often use the main YandexBot user-agent (Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots)) with additional parameters. These partnerships allow advertising agencies and technology providers to integrate with Yandex's services.

Why is a YandexPartner bot crawling my site?

If you are seeing traffic that appears to be associated with a Yandex partner, it is likely related to advertising verification or content syndication. Partners may be crawling your site to verify ad placements or track campaign performance. The frequency of visits depends on your site's relationship with the Yandex ecosystem. Sites with active ad campaigns or frequent content updates may see more partner-related crawling.

What is the purpose of a YandexPartner bot?

The purpose of the YandexPartner framework is to extend Yandex's reach by allowing third parties to leverage its technology. For advertising partners, it provides tools to manage campaigns. For content syndication partners, it enables broader distribution of Yandex-indexed content. For website owners, these partnerships can provide benefits through increased visibility in the Yandex ecosystem and potential revenue from advertising, especially in Russian-speaking markets.

How do I block a YandexPartner bot?

Since YandexPartner traffic typically uses the main YandexBot user-agent, blocking it requires blocking the main bot. This will prevent your pages from appearing in Yandex's search results.

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

User-agent: Yandex
Disallow: /

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

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., Yandex), 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.
