Letting the huge debate around privacy aside, a very important question in this area, for which little is known, is: How much do advertisers pay to reach an individual? In this study, we develop a first of its kind methodology for computing exactly that -- the price paid for a web user by the ad ecosystem -- and we do that in real time. Our approach is based on tapping on the Real Time Bidding (RTB) protocol to collect cleartext a","authors_text":"Nicolas Kourtellis, Nikolaos Laoutaris, Pablo Rodriguez Rodriguez, Panagiotis Papadopoulos","cross_cats":["cs.CY","cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2017-01-24T19:47:14Z","title":"If you are not paying for it, you are the product: How much do advertisers pay to reach you?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.07058","kind":"arxiv","version":3},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:62701d7e53e663615685b420a6ba99a0398b1a763460b2237d5fb38a5ebcb869","target":"record","created_at":"2026-05-18T00:34:31Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"68b168fafea0f2190aef0cd03cc9f93c08e97bc452f276ef3e9b97333e9cc3bc","cross_cats_sorted":["cs.CY","cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2017-01-24T19:47:14Z","title_canon_sha256":"6de2ff7851dfd0313f91b78b75c54a41f7ff4035e350f26be3af7f1142a3f68c"},"schema_version":"1.0","source":{"id":"1701.07058","kind":"arxiv","version":3}},"canonical_sha256":"19b97b2b7e9707e1119e734760ae0babe3c42ef2196c711e58a084532f36b594","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"19b97b2b7e9707e1119e734760ae0babe3c42ef2196c711e58a084532f36b594","first_computed_at":"2026-05-18T00:34:31.214502Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:34:31.214502Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QwiSC27FZ9J+amW8ga22qrSOHw8oKfvxEP+IeoWyk8X8THxZrrt7qs3JLhwpxRvRV1815g/267Qg2euUfcmuCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:34:31.215107Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.07058","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:62701d7e53e663615685b420a6ba99a0398b1a763460b2237d5fb38a5ebcb869","sha256:e94e1f58a10e081fa8564ad35b7dcdeb528ed71b3f40f7a393ded7d9266082c3"],"state_sha256":"d97db0db141697ba1b6d9a231530a7e6f8bcaac3b3b1ccbac69b9ad58348d293"}
