linkfluence bot

The linkfluence bot is a commercial web crawler operated by Meltwater, a leading media monitoring and analytics company. Its purpose is to scan public web pages, blogs, and forums to collect data for brand monitoring, competitive intelligence, and market research on behalf of Meltwater's clients. The bot is well-behaved and respects robots.txt directives.

What is the linkfluence bot?

The linkfluence bot is an intelligence-gathering web crawler for the media monitoring company Meltwater (which acquired Linkfluence in 2021). It is designed to collect and analyze public web data for brand sentiment and market insights. The crawler systematically visits websites, blogs, forums, and social media platforms to gather content relevant to its clients. It identifies itself with the user-agent string linkfluence or YaK/1.0, and it is designed to respect standard web protocols like robots.txt.

Why is the linkfluence bot crawling my site?

The linkfluence bot is visiting your website to collect data for one of Meltwater's clients. It targets content that mentions specific brands, products, or topics that are being monitored. If your site publishes content related to industry trends, consumer opinions, or popular brands, it is a natural target for this crawler's data collection efforts. The frequency of visits depends on the relevance of your content to Meltwater's clients. This crawling is considered authorized as it only accesses publicly available information.

What is the purpose of the linkfluence bot?

The purpose of the linkfluence bot is to serve as a data collection tool for Meltwater's consumer insights and brand monitoring services. The data it gathers helps brands understand their online presence, track public sentiment, and benchmark against competitors. For website owners, there is no direct benefit from being crawled, as the service is designed to benefit Meltwater's clients. However, the crawler is designed to be respectful of server resources and to operate within ethical and legal boundaries, including GDPR.

How do I block the linkfluence bot?

If you wish to prevent the linkfluence bot from accessing your website, you can add rules to your robots.txt file. There are two primary user-agents associated with the service.

To block these crawlers, add the following lines to your robots.txt file:

User-agent: linkfluence
Disallow: /

User-agent: YaK
Disallow: /

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

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., Meltwater), 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.
