If you are getting ready for the Google Ads Measurement Certification, you will find questions that check how well you understand smart bidding strategies. One of the most common and important topics is about Target ROAS bidding.
In this guide, I will break down the correct answer using simple words, real-life examples, and a helpful comparison table. You will also see why the other choices are wrong. By the end, you will know how Target ROAS works and feel more confident about this topic in your exam. Let’s dive into the main point.
Question and Correct Answer
A marketing strategist is interested in target ROAS bidding. How might their agency describe this bidding strategy?
- A) This bidding strategy determines that if a user’s search is likely to generate a conversion with high value, target ROAS will bid low on that search.
- B) This bidding strategy determines that if a user’s search is likely to generate a conversion with low value, target ROAS will bid high on that search.
- C) This bidding strategy uses historical and uploaded data to set the value of a conversion every time a user searches for products or services that are being advertised. Then it automatically adjusts bids for these ads to maximize return.
- D) This bidding strategy analyzes and intelligently predicts the value of a potential conversion every time a user searches for products or services that are being advertised. Then it automatically adjusts bids for these searches to maximize return.
Correct answer: Choice D
This bidding strategy analyzes and intelligently predicts the value of a potential conversion every time a user searches for products or services that are being advertised. Then it automatically adjusts bids for these searches to maximize return.

Why is this the right Answer?
The answer is (D) right because Target ROAS (Return on Ad Spend) is a smart bidding strategy in Google Ads. It looks at how much money you might make from a click before you even pay for that ad. If Google’s AI thinks a person is likely to buy something with high value, it will raise your bid for that user. If the person is not likely to bring in much money, it will lower your bid to save your budget.
Target ROAS is not guessing. It uses real past data and smart learning to make decisions. It checks things like:
- What did similar users do before?
- What is the product or service worth?
- When are people more likely to buy?
By using this data, Google Ads helps you get more value from your ads, not just more clicks. It’s like a smart helper deciding how much to pay each time so you earn more money from what you spend. That’s why this answer is correct.
Why are the other options incorrect?
Let’s take a look at the other choices and why they do not match how Target ROAS actually works.
Option 1:
“This bidding strategy determines that if a user’s search is likely to generate a conversion with high value, target ROAS will bid low on that search.”
This is wrong because it says the opposite of what Target ROAS really does. If Google sees that a user is likely to bring a high-value conversion, it will increase the bid, not lower it. The goal is to make more money by showing your ad to people who are more likely to buy or spend more.
Option 2:
“This bidding strategy determines that if a user’s search is likely to generate a conversion with low value, target ROAS will bid high on that search.”
This is also wrong. Target ROAS tries to give you the best return on your ad money. So if someone is expected to bring in low value, Google will lower the bid to avoid spending too much. Bidding high on low-value results would waste your budget.
Option 3:
“This bidding strategy uses historical and uploaded data to set the value of a conversion every time a user searches for products or services that are being advertised. Then it automatically adjusts bids for these ads to maximize return.”
This sounds close, but it’s not quite right. The confusing part is “uploaded data.” Target ROAS does not depend on extra data that you have to upload. Instead, it uses real-time signals and machine learning to predict conversion value, not just pull numbers from past uploads. That’s why it’s not the best or most complete answer.
Only the correct answer talks about predicting the value of a conversion in real time and automatically adjusting bids to help you get the most return from your ad spend. That’s what makes it the right choice.

Real life example
Imagine Mia runs an online shoe store. She sells both budget sneakers and expensive designer boots. She uses Google Ads to show her products when people search online.
One day, someone searches for “luxury Italian leather boots.” Google’s system predicts this person is likely to buy a high-priced pair from Mia’s store. So, Target ROAS automatically increases the bid to show Mia’s ad in a top spot, because the potential return (profit) is high.
Later, someone else searches for “cheap running shoes.” Google predicts this customer might only spend a small amount. Target ROAS lowers the bid for this user because the return would be much lower.
Mia doesn’t have to manually adjust anything. Target ROAS looks at each search, predicts how valuable it might be, and then sets the best bid amount. This way, Mia spends less on low-return customers and more on high-return ones — all automatically.
This is how Target ROAS helps Mia get the best value for every dollar she spends on ads.
