Cases with a working demo: where the ad source gets lost, what it costs the business and what closes the gap.

## Cases

- [The ad source is lost between domains. For example, the brand site, the city site and the booking platform](https://attribution-lab.nexusnode.ru/cases/cross-domain-journey.md): If the booking happens on another site, the ad that brought it gets no credit in your reports – how to carry the source across domains, with a live demo. (in the demo, GA4, GTM, sGTM, Google Ads)
- [Ad blockers: some conversions never reach Google, and the ads learn without them](https://attribution-lab.nexusnode.ru/cases/server-side-delivery.md): Visitors with ad blockers still book, but Google never sees it and the ads learn without them – three ways to close the gap, and a demo you can check with your own blocker. (in the demo, GA4, GTM, sGTM, Google Ads)
- [Cookie consent for visitors from Europe: what your ads lose and how to lose less](https://attribution-lab.nexusnode.ru/cases/consent-regimes.md): Visitors from Europe who do not accept cookies drop out of Google audiences and conversion tracking – what is mandatory if your company is not in Europe, and how to lose less, with a live demo. (in the demo, GA4, GTM, sGTM, Google Ads)
- [Cookie consent when your company is in the EU or UK: comply with the law and lose less](https://attribution-lab.nexusnode.ru/cases/consent-regimes-eu-company.md): If your company is in the EU or the UK: what the law requires, what Google requires, what data your ads lose without cookie consent and how to lose less, with a live demo.

## What we store about you

The site counts visits with its own analytics: Google Analytics, sent through our own server on this site's domain. Visitors from the EU, the UK and Switzerland get it only after they agree, everyone else can switch it off with the link at the bottom of the page. The site and the demo share one analytics identifier, because both are on the same domain, nexusnode.ru. The call form sends what you type into it. The demo is a separate site, with a page that shows everything it recorded about you.

Cookies this site sets:

- `al_hub_consent` – your analytics choice; 180 days, this site only.
- `_ga` – Google Analytics; this site only.
- `FPID` and `FPLC` – set by our analytics server for the whole nexusnode.ru domain, so they are shared with the demo.

Analytics data goes through our server to Google Analytics and is kept there for 14 months. Requests from the call form are stored on our side.
