如何通过谷歌广告A/B测试提升推广效果 - 安岳SEO专家指南
在谷歌广告投放过程中，许多广告主都会面临关键决策难题：
During Google Ads campaigns, many advertisers face critical decision-making challenges:
• 应该使用eCPC还是tCPA出价策略？
• Should we use eCPC or tCPA bidding strategy?
• 落地页使用类目页还是产品页效果更好？
• Which performs better - category pages or product pages for landing pages?
• 广告文案应该突出产品优势还是服务优势？
• Should ad copy highlight product advantages or service benefits?
这些问题的答案其实可以通过谷歌广告实验(Google Ads Experiments)功能进行科学测试。本文将详细介绍三种广告实验类型及设置方法。
These questions can be answered scientifically through Google Ads Experiments. This article details three types of ad experiments and setup methods.
何时应该使用谷歌广告实验？
When to Use Google Ads Experiments?
日常的小调整(如修改CPC、添加关键词)可以直接操作。但对于高风险改动，如：
Minor daily adjustments (like modifying CPC or adding keywords) can be made directly. But for high-risk changes such as:
• 改变出价策略(eCPC→tROAS)
• Changing bidding strategies (eCPC→tROAS)
• 更换整个落地页结构
• Revamping entire landing page structure
• 修改核心广告文案
• Modifying core ad copy
这些改动可能导致广告表现剧烈波动，使用广告实验可以降低风险，通过科学分流测试不同版本的效果。
These changes may cause significant performance fluctuations. Using ad experiments reduces risks through scientific split testing.
三种谷歌广告实验类型
Three Types of Google Ads Experiments
1. 优化文本广告实验
主要用于测试搜索广告的修改：
1. Text Ad Experiments
Primarily for testing search ad modifications:
• 文案替换(如"快速配送"→"免费配送")
• Copy replacement (e.g. "Fast delivery"→"Free delivery")
• 落地页URL测试
• Landing page URL testing
• 广告文本更新
• Ad text updates
2. 视频广告实验
测试不同视频素材效果(功能较局限)
2. Video Ad Experiments
Testing different video materials (limited functionality)
3. 自定义实验(推荐)
可测试：
3. Custom Experiments (Recommended)
Can test:
• 出价策略
• Bidding strategies
• 定位设置
• Targeting settings
• 关键词匹配类型
• Keyword match types
• 广告创意等
• Ad creatives, etc.
详细设置步骤
Step-by-Step Setup Guide
1. 在广告系列界面点击"实验"→"新建实验"
1. In campaign interface click "Experiments"→"New Experiment"
2. 填写实验名称和描述(建议包含测试内容和日期)
2. Fill in experiment name and description (include test content and date)
3. 选择要测试的原广告系列
3. Select original campaign to test
4. 设置实验目标(转化数/成本/率等)
4. Set experiment goals (conversions/cost/rate etc.)
5. 分配流量(通常50/50分配)
5. Allocate traffic (usually 50/50 split)
6. 选择分配方式：
- 基于搜索(用户可能看到不同版本)
- 基于Cookie(用户固定看到同一版本)
6. Choose allocation method:
- Search-based (users may see different versions)
- Cookie-based (users see same version)
7. 设置实验周期(至少2周)
7. Set experiment duration (minimum 2 weeks)
8. 启用"同步"功能保持其他设置一致
8. Enable "Sync" to keep other settings consistent
9. 创建实验并监控数据
9. Create experiment and monitor data
关键注意事项
Key Considerations
1. 测试改动要显著
避免只修改广告标题中的一个词这类微小改动
1. Make significant changes
Avoid minor changes like modifying just one word in ad title
2. 保证测试时长
至少运行2周，智能出价策略需要更长时间学习
2. Ensure sufficient testing duration
Run for at least 2 weeks, smart bidding needs longer learning
3. 控制单一变量
每次实验最好只测试一个主要变量
3. Control single variable
Best to test only one main variable per experiment
4. 实验数量限制
一个广告系列最多可排期5个实验，但只能同时运行1个
4. Experiment quantity limits
Maximum 5 scheduled experiments per campaign, but only 1 running simultaneously
