الزوّار الذين اتّخذوا إجراءات محدّدة

يمكنك تعبئة قائمة المستخدمين بالأشخاص الذين اتّخذوا إجراءات محدّدة على موقعك الإلكتروني. إذا كنت تستخدم تتبُّع الإحالات الناجحة، يمكنك توجيه الإعلانات لاستهداف الأشخاص الذين سبق لهم إجراء إحالة ناجحة (مثل عملية شراء) على موقعك الإلكتروني.

يمكنك أيضًا توجيه الإعلانات لاستهداف الأشخاص الذين اتّخذوا إجراءً معيّنًا على موقعك الإلكتروني لا تعتبره إحالة ناجحة، مثلاً عندما يضيف أحد الأشخاص سلعة ثم يحذفها من سلة التسوّق بدون إجراء عملية شراء.

المتطلبات الأساسية

لإنشاء شرائح من الجمهور واستهدافها، عليك أولاً:

  1. مراجعة سياسة الإعلانات التي تستهدف الاهتمامات والمواقع الجغرافية. لا يمكن استخدام معلومات حسّاسة عن المستخدِمين لإنشاء شرائح جمهور.

  2. أعِدَّ علامة Google.

    بالنسبة إلى المعلِنين الذين يسعون إلى إنشاء قوائم مستخدمين استنادًا إلى سلوك التطبيقات للأجهزة الجوّالة، عليهم تنفيذ حزمة تطوير البرامج (SDK) لمنصة Firebase أو العمل مع حِزم SDK تابعة لجهات خارجية لتتبُّع السلوك داخل التطبيقات.

1- يمكنك إعداد تتبع الإحالات الناجحة. اتّبِع التعليمات الواردة في النظرة العامة على إدارة الإحالات الناجحة. بعد ذلك، عليك تثبيت علامة Google على موقعك الإلكتروني.

استرداد علامة Google

تحتوي جميع حسابات "إعلانات Google" على علامة Google واحدة على مستوى الحساب يتم إنشاؤها تلقائيًا عند فتح الحساب.

يمكنك استرداد علامة Google في واجهة مستخدم "إعلانات Google" باتّباع تعليمات "مركز المساعدة" أو في Google Ads API عن طريق إنشاء RemarketingAction ثم استرداد علامة Google من خلال إصدار طلب GoogleAdsService.searchStream باستخدام المورد remarketing_action:

SELECT
  remarketing_action.id,
  remarketing_action.name,
  remarketing_action.tag_snippets
FROM remarketing_action
WHERE remarketing_action.resource_name = 'REMARKETING_ACTION_RESOURCE_NAME'

تثبيت علامة Google في موقعك الإلكتروني أو تطبيقك

تتمثّل الخطوة التالية في تثبيت علامة Google في جميع صفحات موقعك الإلكتروني. اطّلِع على مزيد من المعلومات عن إضافة علامة Google إلى موقعك الإلكتروني أو تطبيقك المتوافق مع الأجهزة الجوّالة.

إذا كنت تخطّط لإنشاء شرائح من الجمهور استنادًا إلى عناوين URL للصفحات التي تمت زيارتها فقط، لن تحتاج إلى إجراء أي تعديلات على علامة Google. إذا كنت تستخدم معلَمات مخصّصة، يلزمك تعديل علامتك لتضمينها، كما هو مفصل في الاستراتيجيات المتقدمة لوضع العلامات وإنشاء قوائم تجديد النشاط التسويقي.

يمكنك استخدام أداة Google Tag Assistant للتحقّق من صحة تثبيت العلامة.

مَعلمات علامة Google المضمّنة

يمكنك استخدام مَعلمة تجديد النشاط التسويقي المضمّنة url__ لاستهداف قائمة مستخدمين استنادًا إلى عناوين URL التي زارها المستخدمون على موقعك الإلكتروني، كما هو موضّح في مثال زوّار موقعك الإلكتروني.

مَعلمات علامة Google المخصّصة

يمكنك إضافة مَعلمات علامة Google مخصّصة إلى علامة Google لإنشاء قوائم مستخدمين أكثر تخصيصًا.

قبل إنشاء مَعلماتك المخصّصة، تحقّق من قائمة المَعلمات المحدَّدة مسبقًا لمعرفة ما إذا كانت هناك مَعلمة مناسبة لحالة استخدامك. يؤدي استخدام المعلمات المحددة مسبقًا إلى تسهيل الدمج مع ميزات تجديد النشاط التسويقي الأخرى في "إعلانات Google".

إنشاء قائمة المستخدمين

ولاستهداف الزوّار الذين اتّخذوا إجراءات محدّدة، يجب ضبط الحقل basic_user_list الخاص بعنصر UserList يتضمّن عنصر BasicUserListInfo يحتوي على إشارات إلى الإجراءات التي تستهدِفها، سواء كانت إحالات ناجحة أم إجراءات غير إحالات ناجحة.

للحصول على جولة تفصيلية كاملة لمثال على سيناريو تستهدف فيه المستخدمين بناءً على مجموعة من الإحالات الناجحة والإجراءات غير المتعلقة بالإحالات الناجحة، اطّلِع على نموذج السيناريو.

الزوّار الذين تسبّبوا في إتمام إحالة ناجحة

تحدّد قائمة المستخدمين الأساسية عضويتها كأشخاص بدؤوا إجراء إحالة ناجحة واحدًا أو أكثر على موقعك الإلكتروني. عند إنشاء قائمة أساسية للمستخدمين، عليك تقديم اسم المورد ConversionAction إلى كائن UserListActionInfo، والذي يتم تمريره في النهاية إلى UserList.

ينشئ المثال التالي قائمة مستخدمين أساسية مرتبطة بإجراءَي إحالة ناجحة حاليَين:

Java

private void runExample(
    GoogleAdsClient googleAdsClient, long customerId, List<Long> conversionActionIds) {
  List<UserListActionInfo> userListActionInfoList = new ArrayList<>();

الزوّار الذين اتّخذوا إجراءات بدون إحالات ناجحة

يمكنك إنشاء قائمة مستخدمين أساسية للأشخاص الذين اتّخذوا إجراءات على موقعك الإلكتروني لا تعتبر إحالات ناجحة من خلال ربطها بالرمز RemarketingAction بدلاً من ConversionAction.

استرداد القائمة

لاسترداد قائمة المستخدمين، يمكنك إصدار طلب البحث التالي بلغة طلب البحث في "إعلانات Google" على المورد user_list.

SELECT
  user_list.name,
  user_list.membership_status,
  user_list.membership_life_span
FROM user_list
WHERE
  user_list.resource_name = 'USER_LIST_RESOURCE_NAME'

استهداف القائمة

بعد إنشاء شريحة جمهورك، تتمثّل الخطوة التالية في استهدافها.

قواعد استهداف شريحة من الجمهور

  1. لا يمكن ضبط قوائم المستخدِمين الإيجابية (التي يمكن تقديم عروض أسعار لها) على مستوى الحملة وعلى مستوى المجموعة الإعلانية في الوقت نفسه. يجب إزالة معايير قائمة المستخدمين الإيجابية من جميع المجموعات الإعلانية ضمن حملة ما قبل ضبط مجموعة إعلانية لهذه الحملة.

  2. لا يتوفّر الاستهداف الإيجابي حسب قائمة المستخدِمين إلّا في "الحملات على شبكة البحث". بالنسبة إلى "الحملات على الشبكة الإعلانية"، يجب استبعاد CampaignCriterion التي تحدد user_list.

  3. في "الحملات على شبكة البحث" و"حملات Shopping"، لا تتيح استهدافات قوائم المستخدمين إعداد الحقول التالية:

استهداف الإعلانات لقائمة المستخدمين

وتتشابه هذه العملية مع الأنواع الأخرى من معايير الاستهداف في واجهة برمجة التطبيقات. يوضِّح الرمز التالي كيف يمكنك استخدام AdGroupCriterion لتوجيه الإعلانات في إحدى المجموعات الإعلانية إلى قائمة مستخدمين:
