เมื่อสร้างการทดสอบแล้ว คุณจะต้องสร้างกลุ่มทดสอบหลายกลุ่มเพื่อให้การทดสอบมีข้อมูลเพิ่มเติมเกี่ยวกับสิ่งที่คุณทดสอบ
แขนทดสอบ
ExperimentArm
แสดงการเปรียบเทียบส่วนหนึ่งที่คุณทํากับการทดสอบ การทดสอบทั้งหมดต้องมีกลุ่มควบคุมเพียงกลุ่มเดียวเสมอ กลุ่มนี้เป็นแคมเปญที่มีอยู่ซึ่งใช้เป็นพื้นฐานในการเปรียบเทียบกับกลุ่มอื่น
กลุ่มทดสอบอื่นๆ เรียกว่ากลุ่มทดสอบ ซึ่งคุณจะทําการเปลี่ยนแปลงแคมเปญก่อนเริ่มการทดสอบ
ExperimentArm
ยังมีการตั้งค่า traffic_split
ด้วย ซึ่งจะช่วยให้คุณระบุเปอร์เซ็นต์ของการเข้าชมที่ไปยังกลุ่มทดสอบแต่ละกลุ่มได้ กลุ่มทดสอบแต่ละกลุ่มต้องระบุการแยกการเข้าชม และผลรวมของค่าการแยกการเข้าชมในกลุ่มทดสอบทั้งหมดต้องเท่ากับ 100
เนื่องจากการจํากัดการแยกการเข้าชมนี้ คุณจึงต้องสร้างกลุ่มทดสอบทั้งหมดในคําขอเดียวกัน

ประเด็นสำคัญบางส่วนเกี่ยวกับตัวอย่างข้างต้นมีดังนี้
name
ของกลุ่มทดสอบแต่ละกลุ่มต้องไม่ซ้ำกันภายในExperiment
traffic_split
ทั้งหมดต้องรวมกันได้ 100กลุ่มทดสอบอย่างน้อย 1 กลุ่มต้องตั้งค่า
control
เป็นtrue
ส่วนกลุ่มทดสอบอื่นๆ ทั้งหมดต้องตั้งค่าเป็นfalse
เฉพาะกลุ่มควบคุมเท่านั้นที่จะระบุอาร์เรย์
campaigns
ซึ่งเก็บแคมเปญได้เพียงแคมเปญเดียว
กลุ่มทดสอบ
เมื่อสร้างกลุ่มทดสอบทั้งหมดแล้ว กลุ่มทดสอบ (กลุ่มที่มีการตั้งค่า control
เป็น false
) จะป้อนข้อมูลในช่อง in_design_campaigns
โดยอัตโนมัติ คุณสามารถเรียกข้อมูลช่องนี้จากการตอบกลับของ API ได้ด้วยการกําหนดประเภทเนื้อหาของคำตอบเป็น MUTABLE_RESOURCE
ดังตัวอย่างโค้ด นอกจากนี้ คุณยังดึงข้อมูลผ่านข้อความค้นหา GoogleAdsService
ได้ด้วย โดยทำดังนี้
SELECT experiment_arm.in_design_campaigns
FROM experiment_arm
WHERE experiment_arm.resource_name = "TREATMENT_ARM_RESOURCE_NAME"
แคมเปญที่กําลังออกแบบ
คุณจัดการแคมเปญที่กําลังออกแบบเหล่านี้เป็นแคมเปญปกติได้ ทำการทดสอบการเปลี่ยนแปลงใดๆ กับแคมเปญเหล่านี้ได้ แคมเปญควบคุมจะไม่ได้รับผลกระทบ เมื่อกําหนดเวลาการทดสอบแล้ว การเปลี่ยนแปลงเหล่านี้จะกลายเป็นแคมเปญจริงที่แสดงโฆษณาได้
แคมเปญที่กําลังออกแบบเหล่านี้เป็นแคมเปญฉบับร่างในทางเทคนิค หากต้องการค้นหาใน GoogleAdsService
ให้เพิ่มพารามิเตอร์ include_drafts=true
ลงในข้อความค้นหา
คุณต้องทําการเปลี่ยนแปลงอย่างน้อย 1 รายการในแคมเปญที่กําลังออกแบบก่อนจึงจะกําหนดเวลาการทดสอบได้
