A cookie categorisation tool examines every cookie on a website and assigns it to a purpose-based category, typically strictly necessary, functional or preferences, analytics or performance, and advertising or marketing.
This classification is essential because privacy regulations like GDPR require websites to group cookies by purpose in their consent banners and privacy policies, and to block non-essential categories until the user opts in. The tool works by matching cookie names and domains against a database of known trackers, applying pattern recognition for custom cookies, and presenting suggestions for human review.
Miscategorising a marketing cookie as strictly necessary means it will fire without consent, a direct violation of GDPR and ePrivacy rules. Conversely, incorrectly labelling a necessary cookie as optional may break site functionality for users who decline non-essential cookies.
Accurate categorisation ensures that the consent banner truthfully represents your site’s data practices and that tag-blocking rules operate correctly. It also strengthens your privacy policy’s credibility, because each listed cookie maps to a verifiable purpose.
Seers‘ built-in cookie categorisation tool runs as part of every automated scan. It cross-references detected cookies against a continuously updated database of over ten thousand known trackers and applies machine-learning heuristics for unrecognised cookies. Suggested categories are presented in the dashboard for one-click approval.
Once approved, the categories feed directly into the consent banner and tag-blocking engine, ensuring that visitors see accurate cookie descriptions and that scripts fire only when the appropriate consent is granted. This automation eliminates the manual research and guesswork that make cookie compliance so time-consuming.
