Query su Data Transfer di Campaign Manager 360

Associare le variabili Floodlight alle tabelle temporanee

Genera una corrispondenza tra le variabili Floodlight personalizzate e user_id nella tabella delle attività, che può essere utilizzata per unire i dati proprietari ai dati di Campaign Manager 360.


/* Creating the match temp table. This can be a separate query and the
temporary table will persist for 72 hours. */

CREATE TABLE
  temp_table AS (
  SELECT
    user_id,
    REGEXP_EXTRACT(event.other_data, 'u1=([^;]*)') AS u1_val
  FROM
    adh.cm_dt_activities_attributed
  GROUP BY
    1,
    2 )

/* Matching to Campaign Manager 360 impression data */

SELECT
  imp.event.campaign_id,
  temp.u1_val,
  COUNT(*) AS cnt
FROM
  adh.cm_dt_impressions AS imp
JOIN
  tmp.temp_table AS temp USING (user_id)
GROUP BY

Pubblicazione di impressioni

Questo esempio è utile per la gestione delle impressioni e mostra come trovare il numero di impressioni pubblicate oltre le quote limite o se alcuni potenziali clienti sono stati meno esposti agli annunci. Utilizza queste informazioni per ottimizzare i tuoi siti e le tue strategie e mostrare il numero giusto di impressioni a un pubblico specifico.

/* For this query to run, @advertiser_ids and @campaigns_ids
must be replaced with actual IDs. For example [12345] */

WITH filtered_uniques AS (
  SELECT
    user_id,
    COUNT(event.placement_id) AS frequency
  FROM adh.cm_dt_impressions
  WHERE user_id != '0'
    AND event.advertiser_id IN UNNEST(@advertiser_ids)
    AND event.campaign_id IN UNNEST(@campaign_ids)
    AND event.country_domain_name = 'US'
  GROUP BY user_id
)
SELECT
  frequency,
  COUNT(*) AS uniques
FROM filtered_uniques
GROUP BY frequency
ORDER BY frequency
;

Questo esempio consente di identificare le strategie e i formati degli annunci che determinano aumenti o diminuzioni del numero o della frequenza dei cookie unici.

/* For this query to run, @advertiser_ids and @campaigns_ids and @placement_ids
must be replaced with actual IDs. For example [12345] */

SELECT
  COUNT(DISTINCT user_id) AS total_users,
  COUNT(DISTINCT event.site_id) AS total_sites,
  COUNT(DISTINCT device_id_md5) AS total_devices,
  COUNT(event.placement_id) AS impressions

  AND event.campaign_id IN UNNEST(@campaign_ids)
  AND event.placement_id IN UNNEST(@placement_ids)
  AND event.country_domain_name = 'US'
;

Per restringere la query, puoi anche includere ID sito o posizionamento nella clausola WHERE.

Questo esempio unisce la tabella cm_dt_impressions e la tabella di metadati cm_dt_state per mostrare le impressioni totali, il numero dei cookie per stato e il numero medio di impressioni per utente, raggruppati per provincia o stato geografico del Nord America.


WITH impression_stats AS (
  SELECT
    event.country_domain_name AS country,
    CONCAT(event.country_domain_name, '-', event.state) AS state,
    COUNT(DISTINCT user_id) AS users,
    COUNT(*) AS impressions
  FROM adh.cm_dt_impressions
  WHERE event.country_domain_name = 'US'
    OR event.country_domain_name = 'CA'
  GROUP BY 1, 2
)

Segmenti di pubblico di Display & Video 360

Questo esempio mostra come analizzare i segmenti di pubblico di Display & Video 360. Scopri quali segmenti di pubblico vengono raggiunti dalle impressioni e determina se alcuni hanno un rendimento migliore di altri. Queste informazioni possono aiutarti a trovare il giusto equilibrio tra il numero di cookie unici (mostrando gli annunci a molti utenti) e la qualità (targeting ristretto e impressioni visibili), a seconda degli obiettivi.

/* For this query to run, @advertiser_ids and @campaigns_ids and @placement_ids

Utilizzare i modelli di attribuzione

Ads Data Hub supporta sia i modelli di attribuzione basata sui dati (DDA) sia di attribuzione dell'ultimo clic (LCA) nelle tabelle di conversione di Google Ads. Prima del 19 settembre 2023 veniva supportata solo la LCA. I seguenti esempi ti mostrano come trovare le conversioni che utilizzano entrambi i modelli e come utilizzare la tabella dei metadati delle impostazioni di conversione.

Trovare le conversioni di attribuzione basata sui dati

Questo esempio trova le conversioni che utilizzano il modello DDA:

SELECT
  s.name
  SUM(conv.num_conversion_micros)/1000000 AS num_convs
FROM adh.google_ads_conversions AS conv
JOIN adh.google_ads_conversion_settings AS s
  ON (conv.conversion_type = s.conversion_type_id)
WHERE s.action_optimization = 'Primary'
    AND s.attribution_model = 'DATA_DRIVEN'
GROUP BY 1;

Trovare le conversioni di attribuzione dell'ultimo clic

Per mantenere il comportamento precedente, aggiungi una WHERE clausola alle tue query per filtrare i risultati delle conversioni di attribuzione dell'ultimo clic:

SELECT COUNT(*)
FROM adh.google_ads_conversions
WHERE conversion_type = 123
  AND conversion_attribution_model_type = 'LAST_CLICK';

Utilizzare la tabella dei metadati per filtrare in base al nome di conversione

La tabella dei metadati delle impostazioni di conversione ti permette di filtrare in base a nomi significativi invece di numeri.

Ad esempio, invece di filtrate la conversione in base a conversion_type:

SELECT COUNT(*)
FROM adh.google_ads_conversions
WHERE conversion_type = 291496508;

Utilizza una clausola JOIN, per filtrare utilizzando i campi nella tabella dei metadati delle impostazioni di conversione:

SELECT SUM(num_conversion_micros)/1000000 AS num_convs
FROM adh.google_ads_conversions AS conv
JOIN adh.google_ads_conversion_settings AS s
     ON (conv.conversion_type = s.conversion_type_id)
WHERE s.name = 'LTH Android Order';
SELECT s.name, SUM(conv.num_conversion_micros)/1000000 AS num_convs
FROM adh.google_ads_conversions AS conv
JOIN adh.google_ads_conversion_settings AS s
     ON (conv.conversion_type = s.conversion_type_id)
WHERE s.conversion_category = 'PURCHASE'
  AND s.action_optimization = 'Primary'
GROUP BY 1;

Query sui pod di annunci di YouTube

I pod di annunci raggruppano due annunci in un'unica interruzione pubblicitaria durante sessioni di visualizzazione di YouTube più lunghe. Sono paragonabili a un'interruzione pubblicitaria alla TV, ma con solo due annunci. Gli annunci pubblicati nei pod di annunci rimangono ignorabili. Tuttavia, se un utente salta il primo annuncio, viene ignorato anche il secondo.

SELECT
 cmp.campaign_name,
 imp.is_app_traffic,
 COUNT(*) AS total_impressions,
 COUNTIF(clk.click_id IS NOT NULL) AS total_trueview_views
