بازوهای آزمایشی ایجاد کنید

پس از ایجاد یک آزمایش، باید چندین بازوی آزمایش ایجاد کنید تا اطلاعات بیشتری در مورد آنچه دقیقاً در حال آزمایش آن هستید، به آزمایش ارائه دهید.

بازوهای آزمایش

ExperimentArm نشان دهنده بخشی از مقایسه‌ای است که شما برای آزمایش انجام می‌دهید. همه آزمایش‌ها باید همیشه دقیقاً یک بازوی کنترل داشته باشند. این بازو، یک کمپین موجود است که مبنایی را تشکیل می‌دهد که شما بازوی دیگر را با آن مقایسه می‌کنید.

بازوهای دیگر، بازوهای درمانی نامیده می‌شوند و در این بازوها، قبل از شروع آزمایش، تغییراتی در کمپین ایجاد می‌کنید.

توجه: در حال حاضر محدودیت یک بازوی درمانی در هر آزمایش وجود دارد.

ExperimentArm همچنین شامل تنظیم traffic_split است. این به شما امکان می‌دهد درصد ترافیکی را که به هر بازوی آزمایش هدایت می‌شود، مشخص کنید. هر بازو باید یک تقسیم ترافیک مشخص کند و مجموع مقادیر تقسیم ترافیک در تمام بازوها باید به ۱۰۰ برسد.

به دلیل این محدودیت تقسیم ترافیک، تمام بازوهای آزمایش باید با یک درخواست یکسان ایجاد شوند.

توجه: هنگام ایجاد بازوهای آزمایش نمی‌توانید از شکست جزئی استفاده کنید.

چند نکته کلیدی در مورد مثال بالا:

• name هر بازو باید در کل Experiment منحصر به فرد باشد.
• مجموع traffic_split باید در تمام بازوها به ۱۰۰ برسد.

• دقیقاً باید یک بازو control روی true داشته باشد؛ و بقیه بازوها باید روی false تنظیم شده باشند.

  فقط بازوی کنترل آرایه‌ای campaigns را مشخص می‌کند که فقط یک کمپین را در خود جای می‌دهد.

بازوهای درمان

وقتی همه بازوهای آزمایش را ایجاد کردید، بازوهای درمانی - بازوهایی که control در آنها روی false تنظیم شده است - به طور خودکار فیلد in_design_campaigns خود را پر می‌کنند. می‌توانید با تنظیم نوع محتوای پاسخ روی MUTABLE_RESOURCE مانند مثال کد، این فیلد را از پاسخ API بازیابی کنید. همچنین می‌توانید آن را از طریق یک کوئری GoogleAdsService دریافت کنید:

SELECT experiment_arm.in_design_campaigns
FROM experiment_arm
WHERE experiment_arm.resource_name = "TREATMENT_ARM_RESOURCE_NAME"

نکته: انتخاب فیلد experiment_arm.control برای تشخیص اینکه کدام بازوها، بازوهای درمانی هستند، می‌تواند مفید باشد. از آنجایی که این یک فیلد بولی غیراختیاری است، مقادیر false توسط API بازگردانده نمی‌شوند. یک پاسخ خالی معادل false است.

کمپین‌های درون‌طراحی

شما می‌توانید این کمپین‌های درون‌طراحی را مانند کمپین‌های معمولی در نظر بگیرید. هر تغییری را که می‌خواهید در آزمایش خود روی این کمپین‌ها آزمایش کنید، اعمال کنید؛ کمپین کنترل تحت تأثیر قرار نخواهد گرفت. پس از برنامه‌ریزی آزمایش، این تغییرات در یک کمپین واقعی که می‌تواند تبلیغات را ارائه دهد، پیاده‌سازی می‌شوند.

این کمپین‌های درون‌طراحی‌شده از نظر فنی، کمپین‌های پیش‌نویس هستند. اگر می‌خواهید آنها را در GoogleAdsService پیدا کنید، پارامتر include_drafts=true را به کوئری اضافه کنید.

قبل از اینکه بتوانید آزمایش را برنامه‌ریزی کنید، حداقل باید یک تغییر در کمپین درون‌طراحی ایجاد شود.
