**Observation Mode:**
When you add audiences in Observation mode, your ads continue to show to everyone who searches for your targeted keywords. The audience segments you add simply allow you to monitor how specific groups perform compared to others. This mode does not restrict your reach in any way. You can view performance data segmented by audience, which helps you identify valuable customer segments. Based on these insights, you can then adjust bids for specific audiences that show better conversion rates or engagement. Observation mode is ideal when you want to gather data about how different audiences interact with your ads before making strategic decisions.
**Targeting Mode:**
Targeting mode narrows your ad delivery exclusively to the audience segments you have selected. Your ads will only appear to users who both match your keywords AND belong to your specified audiences. This significantly reduces your potential reach but increases relevance and can improve conversion rates when you have identified high-value audience segments. Targeting mode works best when you have already gathered sufficient data and want to focus your budget on proven audience segments.
**Practical Application:**
Many advertisers start with Observation mode to collect performance data across various audience segments. Once they identify which audiences drive the best results, they may switch to Targeting mode or apply bid adjustments in Observation mode to prioritize those high-performing segments. The choice between modes depends on your campaign goals, whether you prioritize reach and data collection or focused delivery to specific customer groups.
Observation vs Targeting Mode in Google Ads Search
Why It Is Important
Understanding the difference between Observation and Targeting modes is crucial for Google Ads practitioners because it fundamentally affects how your ads reach audiences and how your campaign budget is spent. Choosing the wrong mode can either severely limit your reach or waste budget on irrelevant impressions. This concept frequently appears in certification exams and is essential for campaign optimization in real-world scenarios.
What Is Observation vs Targeting Mode?
When you add audiences to your Search campaigns, Google Ads offers two distinct settings that determine how those audiences interact with your ad delivery:
Targeting Mode (formerly known as Target and Bid): This setting restricts your ad delivery exclusively to the audiences you have selected. Your ads will only show to users who match your chosen audience criteria AND search for your keywords. This narrows your reach significantly but ensures high relevance.
Observation Mode (formerly known as Bid Only): This setting allows your ads to show to all users who search for your keywords, regardless of whether they belong to your selected audiences. However, you can monitor performance data for your chosen audiences and apply bid adjustments to them. Your reach remains broad while you gather valuable insights.
How It Works
When you add an audience to a Search campaign:
1. With Observation Mode: - Your ads continue to appear for all relevant searches - You receive segmented performance data for the audiences you are observing - You can increase or decrease bids for specific audience segments - Total reach is not affected by audience additions - Ideal for testing and learning which audiences perform best
2. With Targeting Mode: - Your ads only appear to users within your selected audiences - All other potential customers are excluded from seeing your ads - Your reach becomes limited to audience size multiplied by keyword relevance - Ideal when you know exactly who your customers are and want focused delivery
Practical Example
A shoe retailer adds an in-market audience for running shoes:
Using Observation: Ads show to everyone searching for running shoes. The retailer can see that the in-market audience converts at 5% versus 2% for general traffic, then applies a +50% bid adjustment for that audience.
Using Targeting: Ads only show to users Google has identified as actively shopping for running shoes. Reach is smaller but potentially more qualified.
Exam Tips: Answering Questions on Observation vs Targeting Mode
1. Remember the key distinction: Observation monitors and adjusts bids; Targeting restricts delivery. If a question mentions maintaining reach while gathering data, the answer is Observation.
2. Watch for scenario-based questions: If an advertiser wants to learn about audience performance before committing, Observation is the correct choice. If they want to focus budget on a specific known audience, Targeting is correct.
3. Understand bid adjustments: Both modes allow bid adjustments, but only Observation mode lets you see comparative data between audience members and non-audience members.
4. Know the reach implications: Questions about maximizing reach while using audiences point toward Observation mode. Questions about precision and exclusivity point toward Targeting mode.
5. Default setting awareness: Observation is typically the default and recommended starting point for Search campaigns when adding audiences.
6. Recognize former terminology: Some questions may reference the old names - Target and Bid equals Targeting mode, Bid Only equals Observation mode.
7. Campaign type context: For Search campaigns specifically, Observation is generally preferred for audience layering because Search intent already qualifies users through keywords.
