Remarketing lists, in-market audiences, Customer Match, and observation vs targeting mode — the audience tools that sharpen Search campaigns beyond keywords alone.
Keywords tell Google what someone is searching for. Audiences tell Google who that person is. The combination of both is where Search campaigns get really precise — and really efficient. I've added remarketing lists to Search campaigns (RLSA) for clients and seen conversion rates double overnight, simply because we were bidding more aggressively for users who had already visited the site. The Search exam tests audience targeting heavily because it's one of the most underused levers in the platform. Here's what you need to know.
RLSA is one of the most important and frequently tested audience features specific to Search campaigns.
Correct answer: B. A feature that allows advertisers to customise Search bids, ads, or keywords for users who have previously visited their website
RLSA lets you layer audience lists onto Search campaigns so you can treat previous visitors differently — bidding higher for users who added something to cart, showing different ad copy to past converters, or even only showing ads to users already familiar with your brand. In practice, RLSA is one of the first things I set up on any Search campaign with reasonable traffic volumes. The conversion rate for returning visitors is almost always significantly higher than for new users, and your bids should reflect that.
This is one of the most commonly tested audience settings — and one of the most commonly misconfigured in real accounts.
Correct answer: B. Observation collects performance data on the audience without restricting who sees the ads; Targeting restricts the campaign to show ads only to users in that audience
This distinction matters enormously in practice. Observation mode is additive — it lets you monitor how a particular audience performs within your existing campaign without limiting reach. Targeting mode is restrictive — it narrows your campaign to only show ads to users in that audience. I always start with Observation to gather data on how an audience converts, then make a deliberate decision about whether to move to Targeting or simply apply a bid adjustment based on what I've seen.
Google's audience types have specific definitions — the exam tests whether you can match the right type to the right intent signal.
Correct answer: B. In-market audiences
In-market audiences are built by Google based on users' recent search and browsing behaviour — specifically identifying people who are actively in the process of researching or comparing purchases in a given category. Unlike affinity audiences (which reflect long-term interests), in-market audiences signal near-term purchase intent. I layer in-market audiences onto Search campaigns in Observation mode to see if they convert at a higher rate, then apply positive bid adjustments to the segments that do.
First-party data features are increasingly important and feature prominently in the modern exam.
Correct answer: C. Customer Match
Customer Match lets you upload a list of customer email addresses, phone numbers, or physical addresses, and Google matches them to signed-in Google users so you can target them with ads. It's one of the most powerful first-party data tools available in Google Ads — particularly valuable for retention campaigns, upsell campaigns, or suppressing existing customers from acquisition-focused campaigns. I use Customer Match regularly for clients with large CRM databases, especially to build "exclude existing customers" lists that prevent wasted spend on users who've already converted.
A conceptual question that tests your understanding of the strategic tradeoff between reach and precision.
Correct answer: B. Because using strict targeting cuts out users who don't match the audience but may still convert, reducing overall opportunity while Observation and bid adjustments allow you to capture both audiences efficiently
Restricting a Search campaign to a specific audience significantly narrows your reach — and in Search, intent signals from keywords are already doing a lot of the qualifying work. A user who isn't in your remarketing list can still be a high-intent prospect searching for exactly what you offer. So in most Search campaigns, the smarter approach is to use audience segments in Observation mode with positive bid adjustments for high-value groups, rather than restricting the campaign entirely. I only use Targeting mode for very specific scenarios — like a campaign designed exclusively for past purchasers or high-value CRM segments.
Not using audience layers in your Search campaigns? You're leaving one of the most effective conversion rate levers completely untouched. I can show you exactly how to set this up.
