Google Analytics, loaded through Google Tag Manager: it counts how many pages are opened and which ones. When on, it sets the _ga and _ga_DDY1JRMMN2 cookies.
Google Ads, loaded through Google Tag Manager: it measures whether a click on one of our Google ads led to an enquiry. When on, it sets cookies whose names start with _gcl_ (such as _gcl_au and _gcl_aw). If you came from an ad, we keep, until you close the tab, the click identifier, the link’s utm_ parameters (the source, the campaign, the ad, and the keyword the ad was shown for) and the page you landed on; if you send the form, they reach us with it. While it is off, nothing of it loads and nothing is stored. We do not use remarketing.
