View-through conversions, click-through conversions, attribution on Display, and the metrics that actually tell you whether a Display campaign is working — for the exam and for real accounts.
Measuring Display performance is genuinely harder than measuring Search performance — and that difficulty is reflected in how heavily the exam tests this topic. In Search, the path from click to conversion is relatively direct. In Display, a user might see your ad five times across three different sites, never click, and then convert directly two weeks later. Attributing that conversion correctly — and understanding what role Display played — is both a measurement challenge and an exam topic. Here's how to approach it.
View-through conversions are one of the most specifically tested measurement concepts in the Display exam.
Correct answer: B. A view-through conversion is recorded when a user sees a Display ad but does not click it, then converts on the website within a defined window; a click-through conversion is recorded when a user clicks the ad and then converts
View-through conversions (VTCs) capture the impression-driven influence of Display — where the ad didn't get a click but may have contributed to the user's eventual decision to convert through another channel. I treat VTCs as a directional signal, not a primary performance metric. They can be inflated by users who would have converted anyway regardless of seeing the ad, so I never use VTCs as the sole justification for a Display campaign's ROI. I look at them alongside click-through conversions and Brand Lift data to build a fuller picture.
Conversion window settings are specific details that the exam tests — they affect how much credit Display gets in your reporting.
Correct answer: C. 30 days
The default view-through conversion window is 30 days — meaning if a user sees your Display ad and converts within 30 days without clicking, it counts as a view-through conversion. You can adjust this in the conversion action settings from 1 day up to 30 days depending on your typical sales cycle. For impulse-purchase products I shorten the window; for considered purchases with longer research cycles I keep it at 30 days. The window you set directly affects how much credit Display campaigns receive in your conversion reports.
This question tests whether you understand the limitations of VTC data — not just how to read it.
Correct answer: B. View-through conversions can overstate Display's contribution because they may include users who would have converted regardless of seeing the ad, without a reliable way to isolate the incremental impact
The fundamental problem with VTCs is that correlation isn't causation — just because a user saw your ad and later converted doesn't mean the ad caused the conversion. They might have been going to convert anyway via organic search, a referral, or direct traffic. Without a proper incrementality test or Brand Lift experiment, it's difficult to know what percentage of VTCs represent genuine Display-influenced conversions. I always present VTCs with this caveat to clients and use them as supporting data rather than primary evidence.
Knowing where to find performance data is as important as knowing how to interpret it.
Correct answer: B. The Placements report, which shows conversions broken down by individual websites, apps, and YouTube channels where ads served
The Placements report is the primary performance diagnostic tool for Display campaigns. It shows exactly which sites and apps your ads appeared on, and — critically — which ones generated clicks and conversions versus which ones just burned impressions. I use this report weekly to exclude non-converting placements, bid up on high-converting ones, and identify patterns in what types of content environments perform best for a specific client. It's the Display equivalent of reviewing keyword performance in Search.
A diagnostic scenario question — the exam increasingly tests real troubleshooting thinking, not just definitions.
Correct answer: B. Poor audience targeting resulting in irrelevant traffic, or a landing page experience that fails to convert the traffic the campaign is sending
High impressions and clicks with low conversions almost always points to one of two problems: you're reaching the wrong people, or the right people are arriving at a page that fails to convert them. I check both simultaneously. In the Placements and Audience reports, I look for targeting signals that suggest broad, unqualified reach. Then I check the landing page — load speed, message match with the ad, clarity of the CTA, and mobile experience. In Display campaigns with this symptom, the fix is usually tighter audience segmentation and a landing page audit, not a bidding adjustment.
Getting lots of Display impressions and clicks but struggling to see them turn into leads or sales? The problem is almost never the ad — it's usually targeting or landing page experience. Let me find out which one.
