Introduction
There are a few things that you need to know before using, and in order to use the system correctly.
Https
Ads will still work if your site is on plain HTTP, but context-aware matching won't work reliably outside your front page in that case. We'd recommend serving your site over HTTPS — not a big ask, since most sites default to it today anyway, but worth being aware of.
Referrer Policy
Modern browsers strip the referrer header by default once you leave HTTPS, unless a page explicitly opts back in. That's why you should add the attribute referrerpolicy="no-referrer-when-downgrade" wherever you embed a link to betweenaffiliates.com, so we can track it properly.
This isn't strictly required, but it's highly recommended: it's what makes per-page statistics accurate (so you can compare how individual pages on your site perform, not just the site as a whole), and it directly feeds context-aware matching, which relies on knowing exactly which page an ad is loading on. We'd recommend adding it on every link, image, script, and iframe tag you use — even for embed types where the referrer is usually implied — since it's the difference between us knowing an ad ran on https://betweenmovies.com/movie/salome-1908/ specifically versus only knowing it came from https://betweenmovies.com/ somewhere.
