Check your CMS and see which cookies it sets (if any). If some of these cookies are not classified as necessary (and can be), please re-classify them by following our Managing Cookies article.
Check the application menu and/or pop-up in your browser to see which cookies are being set when you have consented to them.
Check your pop-up or the compliance dashboard to find out which cookies are third-party or first-party.
Check the source code of your website (using the Elements tab when Inspecting the page) to see if any scripts are included for services that are setting cookies directly.
Have a look in your Google Tag Manager container to see which services have tags set up and are setting cookies (these can also be seen on the pop-up if you know they are already in Google Tag Manager).
