What is the YandexMarket bot?

The YandexMarket bot is a web crawler from Yandex that is designed to collect and index product information from e-commerce websites for the Yandex.Market platform. This service is similar to Google Shopping, allowing consumers to compare products and prices. The crawler is a specialized indexing bot that identifies and catalogs product listings, prices, and availability. It identifies itself with the user-agent string YandexMarket/1.0.

Why is the YandexMarket bot crawling my site?

The YandexMarket bot is crawling your website because it contains product listings or other e-commerce content that Yandex wants to include in its marketplace. The crawler is specifically looking for product names, prices, images, and specifications. The frequency of its visits depends on how often you update your product information. This is generally considered an authorized activity for public e-commerce websites, as it helps drive potential customers to your products.

What is the purpose of the YandexMarket bot?

The purpose of the YandexMarket bot is to power Yandex.Market, a major online marketplace in Russia. By crawling product information, the bot enables consumers to compare products and prices across multiple retailers. For website owners, inclusion in Yandex.Market can significantly increase visibility to Russian-speaking consumers and is a valuable channel for e-commerce businesses targeting this market. The data it collects is used to create structured product listings that can drive qualified traffic from comparison shoppers.

How do I block the YandexMarket bot?

To prevent the YandexMarket bot from accessing your e-commerce site, you can add a specific disallow rule to your robots.txt file. This will prevent your products from appearing in the Yandex.Market comparison service.

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

User-agent: YandexMarket
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.
