Companies Radar

About our crawler

Companies Radar lists technology companies. To keep company profiles accurate, our crawler (the “Data Feeder”) occasionally reads the public homepage of a company's website. Everything it finds is reviewed by our team before anything is published.

How to recognise it

Our requests identify themselves with this User-Agent:

Mozilla/5.0 (compatible; CompaniesRadarBot/<version>; +https://companiesradar.com/about-our-crawler)

What it collects – and what it doesn't

  • Business information only: company name, website, description, country and address, general business contact (such as info@ or sales@ addresses and the main phone number), links to official social media profiles, and the company's own logo.
  • It does not collect personal data about employees, photos, screenshots, or content from other directories and review sites.
  • Descriptions found on websites are kept only as a reference; profiles are published only with text written by our team or supplied by the company.

How it behaves

  • It follows your robots.txt, including Crawl-delay.
  • It makes one request at a time to your site, waits between requests, and backs off when your server is busy.
  • It reads the homepage and your logo – it does not crawl your whole site.

Website health checks

For listed companies we also check that the website still works – about once a month, and daily for a few days while it is failing. A check is one request for your homepage with the same User-Agent (like an uptime monitor: we look at the status and the security headers, not the content), a look at your HTTPS certificate, and public DNS and domain-registration records. It also checks that the profile's social and product links still exist. The result feeds the profile's Website Score; the details are shown only to the company and our team. Because these checks do not read your pages, a robots.txt rule does not stop them; they end when the profile is removed.

How to block it

Add these lines to the robots.txt file at the root of your website:

User-agent: CompaniesRadarBot
Disallow: /

Corrections and removal

Company representatives can ask us to correct or remove a profile. A contact address will be published here soon. Once a removal is approved, your domain is added to a do-not-list, so our crawler and imports never add it again.
