Prioritize audience insights that are closest to revenue (your first-party data)
Use “Your data insights” to reverse-engineer who actually converts
If you want audience insights that reliably improve performance, start with insights based on people who already engaged with you: site visitors, app users, video viewers, customer lists, and (most importantly) converters. The practical goal isn’t to admire the data; it’s to identify which characteristics show up disproportionately among converters so you can put more budget behind those patterns (or stop paying for the wrong ones).
In “Your data insights,” you’ll typically see breakdowns that include demographics, locations, devices, and how your first-party lists over-index against broader benchmarks. This is where you find the difference between “who you think buys” and “who actually buys.” For example, if “All converters” skews heavily toward mobile and certain age ranges, that should immediately influence your mobile landing page experience, creative formats, and geo/device bid strategy where applicable.
Two operational realities matter here. First, insights only appear when lists are large enough; a common threshold is at least 1,000 active users in the previous 30 days to show insights. Second, insights can vary by country availability and platform updates, so if you notice fewer dimensions than you used to see, that isn’t always a tracking failure—it can be a reporting limitation in your market at that time.
Turn Customer Match into a high-quality “seed” for optimization (not just retargeting)
Customer lists are one of the strongest audience inputs you can provide because they represent real customers and qualified leads. The performance unlock is usually match rate and freshness. Uploading multiple identifiers per contact (for example, email plus phone plus address where you have it) typically increases match rates and usable reach. As a benchmark, many advertisers land in the ~29% to ~62% match-rate range; if you’re far below that, treat it like a data hygiene problem first (formatting, missing country codes, inconsistent fields), not a media problem.
Once you have meaningful lists (past purchasers, high-LTV customers, repeat buyers, qualified leads), you can use them to guide bidding and audience strategy across channels, and as a foundation for growth audiences in campaign types that support lookalike-style expansion.
Use audience reporting to decide what to target, what to observe, and what to exclude
Start in the Audiences report (it’s the cleanest “single pane” view)
The Audiences report consolidates performance across demographics, audience segments, and exclusions at the campaign, ad group, and account level. Conceptually, it’s organized into a few modules that matter for optimization: an audience summary (where applicable), an audience performance scorecard, demographics, audience segments (affinity, in-market, detailed demographics, your data, custom segments, life events), and exclusions.
When you’re optimizing, don’t just look at conversion rate. Compare cost, conversion value (if you track it), and share of results. If a segment drives cheap clicks but weak conversion value, it may be “engagement bait,” not a business driver.
Understand the difference between “Targeting” vs “Observation” (and use each on purpose)
One of the most common mistakes I see is restricting reach too early. “Targeting” means you’re narrowing delivery only to the audiences/content you selected. “Observation” lets you measure how a chosen audience performs without restricting who can see your ads, and it enables you to use that performance data to decide what to build next (new ad groups, new creative angles, bid changes where applicable).
A simple rule: use Observation when you’re still learning (especially on intent-based campaigns where keywords or queries do the heavy lifting), and use Targeting when you genuinely want to constrain delivery (common in Display and many Video setups).
Know which audience segment types are available (because it changes by campaign)
Not every campaign type supports every segment type. In broad strokes, affinity, in-market, detailed demographics, life events, custom segments, and your data are widely used across Display and Video-oriented campaigns. Search and Standard Shopping tend to rely more on in-market, demographics, and your data in many setups. Demand Gen is also where you’ll commonly see lookalike-style segments available (based on “seed” lists), which is why your Customer Match and converter lists become strategically important, not just tactically useful.
Don’t forget exclusions (they’re often the fastest efficiency win)
Most advertisers think of audiences as “who to add,” but excluding clearly unprofitable audiences can be just as impactful—especially when you’re using automation that can explore broadly. If you have segments that consistently consume spend and underperform on your core KPI, exclusions are a clean way to reduce waste without overcomplicating the account.
Optimize AI-driven campaigns using the right audience inputs (and the right expectations)
Performance Max: use audience signals to steer learning, not to “lock targeting”
In Performance Max, audience signals are optional—but in practice, they’re one of the best ways to shorten the learning curve, especially for new accounts, new products, or new markets. The key is expectation-setting: signals are guidance, not strict targeting. The system can still show ads to people outside your signals when it predicts they’re likely to convert.
The strongest signal sets usually combine first-party lists (site visitors, app users, customer lists, video viewers) with custom segments built from high-intent themes (keywords, URLs, or apps that represent your ideal buyer), plus demographic constraints and additional segments like in-market, affinity, life events, and detailed demographics where they truly reflect your customer base.
Optimized targeting: understand how it works before you judge it
Optimized targeting gives certain campaign types the flexibility to find the people most likely to convert, using your inputs as a starting point and then expanding beyond them if it finds better-performing traffic. It can even reduce or stop serving on your original signals if it identifies stronger opportunities elsewhere, which surprises advertisers who assume targeting inputs are always “sticky.”
Operationally, optimized targeting needs time and conversion data to stabilize. A practical evaluation window is at least 2 weeks, and for brand-new campaigns it’s smart to wait until you’ve generated meaningful conversion volume (a common guideline is 50 conversions) before making hard calls. Optimized targeting is available in specific campaign types (not universally), and it’s treated differently in Performance Max versus other formats—so always evaluate it within the context of the campaign type you’re running.
Audience expansion (Video goals): use it when reach is the goal, not when precision is the goal
Audience expansion is designed to help you reach more people similar to your selected audiences while maintaining your CPM/CPV bids, and it’s tied to Video campaigns using specific upper-funnel goals like awareness/reach and consideration. If your primary goal is efficient conversion at a strict CPA/ROAS, you’ll typically lean more on conversion-optimized approaches; if your job is to scale reach into the “right kind” of audience without micromanaging segments, expansion can be useful. As with other automated reach features, brand safety controls like content exclusions are still respected.
Use Audience Insights (and creative-level insights) to improve messaging, not just targeting
Persona audience insights: look for high “Index,” not just high volume
Audience insights are designed to show the unique characteristics, interests, and behaviors of user groups that view your ads and convert—especially when you’re using AI-driven features like automated bidding and optimized targeting. The most useful fields are “share of conversions” (how much of your conversions come from a segment) and “index” (how overrepresented that segment is among converters versus your broader targeted population). High-index segments often reveal the “real buyer,” even when the segment isn’t the biggest by volume.
Asset audience insights: connect creatives to the audiences they resonate with
If you run asset-based campaigns (for example, formats that use creative asset groups), asset audience insights can show which audience segments your assets are resonating with. This is a powerful creative feedback loop: when a message or visual performs exceptionally well with a specific audience, your next step is usually to produce more variations that keep the same core promise but test different angles (benefits, objections, use cases) for that audience.
Use Insights Finder for planning and persona development (when you need new angles)
Translate “Share,” “Index,” and “Relevance” into actionable targeting and creative themes
Insights Finder is built to turn aggregated, anonymized signals from Search and YouTube into planning insights. Practically, it helps you understand audience composition (age, gender, location, lifestyle segments like affinity and in-market), what else they’re interested in, and what they watch. The power move is using “index” to find what’s distinctive about the audience (not what’s common to everyone), then turning those distinctive interests into creative hooks, offers, and landing page framing.
Use baseline comparisons intentionally. If you’re analyzing “Females 25–34 interested in X,” set a baseline of “Females 25–34” so you see what’s unique beyond age/gender. Also remember the privacy mechanics: these insights rely on thresholds and privacy protections that can cause small fluctuations or missing results for very niche definitions. Data refresh timing matters too; audience-oriented data is commonly refreshed on a weekly cadence looking back at the last 30 days unless you select a different period.
Critical monthly checklist: the audience insights that reliably move performance
- Review “Your data insights” on converter-based lists first (All converters, purchasers, qualified leads). Identify the top-overindexing demographics, geos, devices, and in-market/affinity overlaps, then decide whether to adjust bids, targeting, or creatives.
- Check the Audiences report for trends and waste by demographics, audience segments, and exclusions. Look for segments with sustained spend and weak outcomes, then exclude or restructure.
- Open Audience insights and note the top personas by “Index”, then pressure-test whether your messaging and landing pages speak to those personas explicitly.
- For asset-based campaigns, use asset audience insights to identify which creatives resonate with which segments, then produce 3–5 new variants that keep the winning “promise” while testing new angles.
- In Performance Max, refresh audience signals quarterly (or after major product changes) by adding updated customer lists, recent converter lists, and new high-intent custom segments based on what’s currently selling.
- Maintain Customer Match hygiene: upload more identifiers where available, fix formatting, and keep lists fresh so match rates and scale don’t decay over time.

To optimize campaigns with audience insights, start with the signals closest to revenue: use Google Ads “Your data insights” to analyze who actually converts (purchasers, qualified leads, high-value customers) and look for over-indexing patterns across demographics, location, device, and audience overlaps, then validate those findings in the Audiences report to separate profitable segments from “cheap click” traffic and apply exclusions where needed; on Search and Shopping, collect most audience learnings in Observation before you narrow reach, while for Display/Video/Demand Gen you can use Targeting more deliberately, and for Performance Max treat audience signals as guidance you refresh as offers and customer mix change. If you want help turning these insights into consistent, repeatable actions, Blobr connects to your Google Ads and runs specialized AI agents that continuously spot waste and opportunities, with agents like Headlines Enhancer to align messaging to the audiences responding best and a Campaign Landing Page Optimizer to keep landing pages and intent aligned as you iterate.
