A first-party cookie is a code that gets generated and stored on your website visitors’ computers by default when they visit your site.
A first-party cookie will provide information about what users did while visiting your website — how often they visit it and other basic analytics that you can use to help develop an effective marketing strategy.
Third-party cookies are tracking codes that are placed on a web visitor’s computer after being generated by another website other than your own. When a web visitor visits your site and others, the third-party cookie tracks this information and sends it to the third-party who created the cookie — which might be an advertiser.
