Google’s audience targeting options have expanded significantly — but for lead generation, most of them don’t move the needle as much as people expect. Here’s what actually works.
What Audience Targeting Options Does Google Ads Offer?
In-Market Audiences: People Google has identified as actively researching and considering purchases in a specific category. Updated weekly based on search behavior, content consumption, and website visits.
Affinity Audiences: People with demonstrated long-term interests in broad categories (Home & Garden, Business Professionals, etc.). Based on overall browsing patterns over time.
Customer Match: Upload your existing customer email list and Google matches it to Google accounts. Allows targeting or exclusion of your existing customers, or building lookalike audiences based on your customer data.
Similar Segments: Google builds audiences similar to your existing converters or customer match lists.
Remarketing Lists for Search Ads (RLSA): Adjust bids on Search campaigns for people who have previously visited your site.
Which Audiences Work Best for Lead Generation?
In-Market Audiences: Worth Testing
For lead generation, In-Market Audiences are the most relevant option because they identify people actively considering purchases right now — not just people with general interests.
For a home services business, Google has In-Market segments for ‘Home & Garden,’ specific service categories, and ‘Home Improvement.’ Layering these on your Search campaigns as observation (not targeting) first lets you see if people in these segments convert at a better rate than average.
If they do, you can add a positive bid adjustment to bid more aggressively for these users.
RLSA: High Value for the Right Businesses
Adjusting Search bids for past site visitors is one of the more reliable audience tactics for lead gen. People who have already visited your site and are now searching your keywords again are highly qualified — they came back.
Bid 20-50% higher for these users. They convert at meaningfully higher rates in most accounts I manage.
Customer Match: Valuable for Exclusion
For lead generation, Customer Match is often most useful for excluding people rather than targeting them. Upload your existing client list and exclude them from acquisition campaigns — stop spending money showing ads to people who already hired you.
For businesses with strong repeat customers, Customer Match can also be used to target past customers with service renewal or upsell campaigns.
Affinity Audiences and Similar Segments: Usually Marginal
For most lead gen campaigns, Affinity Audiences add volume without proportional quality improvement. The segments are broad enough that the targeting benefit is minimal.
Similar Segments can work well for Display and YouTube awareness campaigns but rarely improve Search performance significantly.
How Should You Use Audience Targeting on Search Campaigns?
The best practice for Search campaigns: add audiences in Observation mode first, not Targeting mode.
Observation mode shows you how different audiences perform within your existing campaigns without restricting who sees your ads. You can see conversion rates, CPL, and lead quality by audience segment before deciding whether to bid up on high performers or exclude low performers.
After 4-6 weeks of data, apply bid adjustments: +20-30% for segments converting at above-average rates, -20-30% for segments converting below average.
Targeting mode (restricting your campaign to only show ads to specific audiences) is appropriate for Display and YouTube but should be used carefully on Search — you might exclude high-intent searchers who don’t happen to fit your target audience profile.
