What is in DuckDuckGo Tracker Radar?
Tracker Radar is actually two compendiums of information:
1. A file for each third-party domain (usually associated with tracking, but not always) containing detailed information about it.
See the documentation for a full rundown, but here is a brief explanation of the major components captured:
2. A file for each parent entity, associating it with domains.
- Prevalence – How common this domain is in our crawl.
- Sites – The actual count of sites this domain was found on in our crawl.
- Categories – High level reasons for using this domain as a third party.
- Fingerprinting – How likely this domain is to be using fingerprinting techniques as a third party.
- Cookies – How often this domain was found setting cookies as a third party.
- Performance – Impact of loading resources from this domain.
- Owner – Parent entity.
- Resources – Scripts, pixels, and other common resources this domain uses.
- Subdomains – Subdomains these resources may be found on.
An entity file lists all the domains that an entity owns. These domains are found in our crawl and cross-referenced with domains and entity names found in WHOIS and SSL certificates. This list can be used to accurately determine when a tracker is being used in a third-party context.
For example, we found doubleclick.net on 29,758 of the sites in our current survey (68%). Since it is owned by Google, which has 479 domains in our data set, this means doubleclick.net is being used on sites not owned by Google ~98% of the time.
Taken together, Google-owned domains are referenced on 93.2% of the sites we surveyed. That is shown above as 'prevalence'.
Even more important is, that someone create a hosts file (for eg. PiHole) which use these domains!:
It is possible that you can create a hosts file with include all domains? So we can use that with eg. PiHole Would be awesome!
