Digital marketing tool such as email service providers and analytics platforms often append tracking parameters to URLs. These are helpful for marketers, but can also severely decrease the effectiveness of page caching tools such as Varnish.
The purpose of this repository is to keep a centralized list of tracking query parameters used by the huge range of online marketing tools in use today.
The lists is contained in data.csv. The file contains 3 columns...
- Param This is the query parameter appended to URLs
- Platform This is the platform that is responsible for appending this parameter
- Confirmed In A reference to the query parameter
The intention is to use this list to form a blacklist for your page cache implementation.
If you come across a tracking parameter that is missing from this list, by all means, make a contribution. In order to do so, please fork the repository and issue a pull request to the master branch. Please include the "Confirmed In" column to show where this query parameter is referenced.
