subito.it

Classifieds Board
IT

Subito.it is Italy's largest classifieds board. Home-page capture: 172 requests, 17 domains. There is a Didomi consent-collection platform to the IAB standard, and in a clean session its consent string means «no consent for any purpose». In the site's favour: Google's advertising delivery observes this — the actual ad request goes out with this string, that is, the advertising is non-personalised. But other services fire before consent: the AppsFlyer marketing attribution SDK, the Google AdSense advertising tag with analytics allowed by default, and the site's own analytics service. That is, the advertising delivery respects the refusal, while the marketing attribution and analytics start before consent.

Timeline of the leak

320 ms · consent platform and advertising library
The Didomi consent-collection platform and the Google Ad Manager advertising library load simultaneously. At this stage the library only prepares the ad slots.
2222 ms · Subito's own analytics
The site's own analytics service (collector) begins collecting events. This is first-party analytics on Subito's domain, before consent.
2377 ms · AppsFlyer marketing SDK
The AppsFlyer marketing-attribution SDK loads. It is listed as a partner in the site's own consent system, that is, its launch requires prior consent — and it is not given.
2674 ms · AdSense advertising tag
The Google AdSense advertising tag sends a utility request. The consent signal shows that analytics is allowed by default.
consent string — «no»
The Didomi platform forms a consent string that means the absence of consent for all purposes. No decision was made in the session, no cookie was set via the headers.
around 89 seconds · ad delivery with the «no consent» flag
The actual Google ad request goes out with the attached «no consent» string — the advertising is non-personalised. Google observes this part correctly.

Indicators of GDPR non-compliance

Context

www.subito.it is Italy’s largest classifieds platform (buying and selling goods, cars, real estate, services). The data controller is the Subito operator. The site is commercial, monetised among other ways by publisher advertising. Capture: 172 requests to 17 domains, the home page, taken on a clean Edge browser with no VPN and no blocker. There is a Didomi consent-collection platform to the IAB standard. The technical stack includes Google publisher advertising, marketing attribution and own analytics.

Who receives the data

Spotted here were: Google, AppsFlyer. Google is present through publisher advertising (Ad Manager and AdSense) — Subito displays ad blocks. AppsFlyer is a marketing-attribution service that tracks the effectiveness of advertising campaigns. Additionally, the site’s own analytics service works.

Yes, the site has a Didomi consent-collection platform to the IAB standard. In a clean session it forms a consent string that, when decoded, means: consent is not given for any purpose. And here it is important to note the positive: Google’s advertising delivery observes this string. The actual ad request goes out with the attached «no consent» flag, that is, the advertising is non-personalised. This counts in the site’s favour.

Before consent, the following fire:

  • the AppsFlyer marketing-attribution SDK — and it is listed as a partner in the site’s own consent system;
  • the Google AdSense advertising tag — with analytics allowed by default;
  • the site’s own analytics service. Marketing attribution and analytics are non-technical purposes requiring consent. AppsFlyer, in addition, is explicitly listed as a partner in the site’s consent system, that is, the platform itself acknowledges that its launch should go after the choice. Here it loads in the first seconds.

A mixed picture

Subito has a dual picture, and it is worth separating. Google’s advertising delivery is set up correctly: with no consent the advertising is non-personalised, the «no consent» flag is transmitted. But in parallel the marketing SDK and analytics start before consent. That is, one part of the stack observes the refusal, and another does not.

Conclusion

Subito.it is a moderate case with a mixed picture. Google’s advertising delivery is configured to observe consent — with no consent the advertising is non-personalised, and this distinguishes the site favourably. But the AppsFlyer marketing-attribution SDK and the advertising tag with analytics by default fire before consent, and AppsFlyer is explicitly named a partner in the site’s consent system. The main takeaway for the reader: the advertising delivery observing consent is correct, but it does not close the question if, alongside, marketing attribution and analytics switch on before the choice. It would be enough to switch their launch into consent-waiting mode — just as has already been done for the advertising delivery.

1. Subject of the complaint
I am filing a complaint regarding the processing of my personal data by the website subito.it.

2. Circumstances
I visited the website subito.it and found indications that the processing of my personal data does not comply with the GDPR. The technical analysis published on gdpru.eu on 20 June 2026 (open methodology, reproducible measurements) documents the following indications:

1) The site has a Didomi consent-collection platform to the IAB standard (TCF), and in a clean session its consent string, when decoded, means that consent is not given for any purpose. Google's advertising delivery observes this: the actual ad request goes out with the attached «no consent» string, that is, the advertising is non-personalised, and this counts in the site's favour. But other services fire before consent. The AppsFlyer marketing attribution SDK loads — and it is listed as a partner in the site's own consent system, that is, its launch requires prior choice. The Google AdSense advertising tag sends a utility request with analytics allowed by default. The site's own analytics service (collector) begins collecting events. All of this happens in the first seconds, whereas consent is not given. Marketing attribution and analytics are non-technical purposes requiring consent, and here they start before it.
