There are numerous signals that Smart Bidding evaluates during every auction. Device type is one key signal, as user behavior varies between mobile, desktop, and tablet. Location signals consider where the user is physically located and their location of interest. Time-based signals include day of week and time of day, recognizing that conversion rates fluctuate throughout different periods.
Audience signals examine remarketing lists, allowing the system to bid differently for users who have previously interacted with your website versus new visitors. The actual search query itself serves as a powerful signal, going beyond just the keyword match to understand user intent more precisely.
Browser and operating system data help identify patterns in how different technology users convert. Language settings provide context about the user's preferences. Ad characteristics, including which creative elements are being shown, factor into bid decisions.
For Search campaigns specifically, Smart Bidding also considers search partner data and interface differences across various Google properties. Price competitiveness signals in Shopping campaigns help understand how your pricing compares to competitors.
The power of Smart Bidding lies in its ability to process these signals simultaneously in milliseconds, something impossible for manual bidding. The system learns from historical conversion data and continuously improves its predictions. Cross-signal combinations reveal patterns that individual signal analysis would miss.
By leveraging these comprehensive signals, Smart Bidding strategies like Target CPA, Target ROAS, Maximize Conversions, and Maximize Conversion Value can make informed bid adjustments for every single auction, ensuring your budget is allocated toward the opportunities most likely to achieve your advertising goals.

What Are Smart Bidding Signals?
Smart Bidding signals are the various data points and contextual information that Google's machine learning algorithms analyze in real-time to optimize bids for each auction. These signals help determine the likelihood of a conversion and adjust bids accordingly to maximize performance.
Why Smart Bidding Signals Are Important
Understanding Smart Bidding signals is crucial because:
• They represent the foundation of automated bidding strategies • They enable bid optimization at a scale impossible for manual management • They consider factors that advertisers cannot access or act upon manually • They process millions of data combinations in milliseconds during each auction
Key Smart Bidding Signals to Know
Device: Mobile, desktop, or tablet - bids adjust based on device performance patterns.
Location: Physical location and location intent help predict conversion likelihood based on geographic data.
Day and Time: Time of day and day of week patterns influence bid adjustments.
Remarketing Lists: Whether a user is on your remarketing list affects their predicted conversion rate.
Browser: Different browsers show varying conversion patterns.
Operating System: iOS, Android, Windows, etc., each have distinct user behaviors.
Language: The user's language setting provides contextual relevance.
Ad Characteristics: Which ad creative is being shown impacts expected performance.
Search Query: The actual search terms entered by users provide intent signals.
Time Since Last Site Visit: Recency of engagement indicates purchase readiness.
Product Attributes: For Shopping campaigns, product price, competitiveness, and seasonality matter.
How Smart Bidding Signals Work
During every auction, Google's algorithms:
1. Collect all available signal data about the user and context 2. Analyze historical patterns from your account and similar advertisers 3. Calculate the probability of conversion for this specific auction 4. Set an appropriate bid based on your chosen strategy and targets
This happens in real-time for every single search query, allowing for auction-time bidding optimization.
Exam Tips: Answering Questions on Smart Bidding Signals
Tip 1: Remember that Smart Bidding uses signals that advertisers cannot manually adjust for, such as browser, operating system, and actual search queries. This is a key differentiator from manual bidding.
Tip 2: Know the difference between signals available to all Smart Bidding strategies versus those specific to certain strategies. For example, Shopping-specific signals include price competitiveness and seasonality.
Tip 3: When asked about the benefits of Smart Bidding, focus on the ability to process multiple signals simultaneously and make real-time adjustments at auction time.
Tip 4: Questions may present scenarios asking which signal would be most relevant. Consider the context - remarketing list membership is critical for return visitors, while location matters for local businesses.
Tip 5: Understand that Smart Bidding requires sufficient conversion data to learn effectively. Questions about implementation often reference minimum conversion thresholds.
Tip 6: Be prepared for questions comparing manual bid adjustments to automated signals. Remember that Smart Bidding considers cross-signal interactions that manual strategies cannot replicate.
Tip 7: Watch for answer choices that mention signals Smart Bidding does NOT use, such as competitor bid amounts or quality scores of competitors.
