What is Quora-Bot?

Quora-Bot is the web crawler for the popular Q&A platform Quora. It functions as an indexing crawler, searching the web for content that could be relevant to questions asked on the platform or that could expand Quora's knowledge base. The bot typically identifies itself in server logs with the user-agent string Quora-Bot/1.0. It is designed to respect standard web crawling protocols and adheres to robots.txt directives.

Why is Quora-Bot crawling my site?

Quora-Bot is visiting your website to discover and index content that may be valuable for Quora users. This could be because your site contains high-quality informational content, your content has been linked to from Quora, or it covers topics frequently discussed on the platform. The frequency of visits depends on your site's relevance and authority on these topics. This crawling is generally considered an authorized activity as part of the normal functioning of the web.

What is the purpose of Quora-Bot?

The primary purpose of Quora-Bot is to enhance Quora's knowledge base by discovering relevant content from across the web. This helps the platform connect user questions with potential external resources and improve the quality of answers. For website owners, having your content discovered by Quora-Bot can lead to increased visibility and referral traffic if your site is referenced in answers on the platform. However, like any crawler, it does consume some server resources during its visits.

How do I block Quora-Bot?

To prevent Quora-Bot from accessing your website, you can add a specific disallow rule to your robots.txt file. This is the standard method for managing access for web crawlers.

Add the following lines to your robots.txt file to block this bot:

User-agent: Quora-Bot
Disallow: /

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

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., Quora), 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.
