Cookies (First- & Third-Party)
Cookies are small files a website stores in your browser to remember things between pages and visits — that you’re logged in, what’s in your cart, or that analytics has seen you before. First-party cookies are set by the site you’re on; third-party cookies are set by other domains, often ad networks.
Why it matters
Cookies are how most analytics recognise returning visitors and stitch a session together. As browsers block third-party cookies and privacy rules tighten, measurement gets harder — more visitors look “new,” and some aren’t counted. A big reason your numbers are an estimate, not a census.
The privacy angle
Consent banners exist largely because of cookies. When visitors decline, analytics may not set them at all — which is why consent mode and data gaps matter.
