How to Target Audiences in DV360: Options, Setup and Tips

Audience targeting decides who your DV360 budget is spent on. Set it well and most impressions reach people who could plausibly buy from you. Set it badly and you either pay for the wrong crowd, or build an audience so small that the line item barely spends.

The settings in Display & Video 360 are quick to learn. The judgement calls around them, such as how many layers to stack and when to let Google widen the audience, are where most of the money is saved or wasted. Audience targeting lives at the line item level, so if you have not built a campaign yet, start with our guide on how to create a campaign in DV360.

What audience targeting options does DV360 offer?

DV360 offers five families of audience lists, plus demographic and location targeting. Google's help pages group the lists as first-party, third-party, Google audiences, combined audiences and custom lists.

On cost, Google's help says first-party lists and DV360's own interest audiences are free to use. Third-party providers charge a data fee, and DV360 shows that CPM beside each segment. It is added to what you pay for media.

Two more layers sit alongside the lists:

• Demographics: age, gender, parental status and, in some markets, household income.
• Geography: countries, states, cities and postal codes, or a radius around an address, business or set of coordinates. Google's help sets the smallest radius at 1 km, and the area must hold at least 1,000 people.

Audience targeting is about who sees the ad. If you would rather control where it appears, such as cricket scorecards or personal finance articles, read our guide to contextual targeting in programmatic advertising. Most good plans use both.

Which audience should you start with?

Start from the campaign objective, not from the list of segments. Each stage of the funnel suits a different type of audience.

Awareness. Keep it broad. Use age, gender and location, and perhaps one or two affinity segments. A paint brand launching a new range in Maharashtra might target adults aged 25–54 in the state, add an affinity segment for home decor, and stop there. On premium OTT or news deals, the choice of publisher often does most of the targeting for you.

Consideration. Use in-market segments and custom intent lists. An NBFC promoting two-wheeler loans could pair in-market segments for motorcycles with a custom intent list built from terms like "bike loan EMI" and the URLs of popular two-wheeler review sites. Our NBFC and lending planning page shows how lenders usually layer this.

Conversion. Use first-party lists: people who viewed a product page, started an application or left items in a cart. Our guide to retargeting campaigns in DV360 covers windows, caps and creative for this stage. If you are not sure what data you have or how to bring it in, read how to use first-party data in programmatic advertising.

How do you add audience targeting to a line item?

The steps are short. YouTube line items set audiences and demographics at ad group level, but the logic is the same.

1. Open the line item and go to its targeting.
2. Add audience lists from the first-party, Google, custom, third-party or combined options. Google's help notes that a line item targets either a combined audience or individual lists, not both at once, so if you use a combined audience, build your exclusions into it.
3. Add exclusions, such as existing customers or people who converted in the last 30 days.
4. Set demographics and geography.
5. Check the forecast or inventory estimate before saving. If the numbers look thin, loosen something now rather than discovering it after a week of underspend. Our guide to forecasting impressions in DV360 shows where to look.
6. Save, then watch delivery closely for the first two or three days.

How do AND and OR work in DV360 audience targeting?

Lists in the same group on a line item work as OR, and Google audiences are joined to your own lists with OR as well. So if you add a Google in-market segment and one of your own lists to the same line item, someone on either one can see the ad. It does not narrow the audience to people on both.

To require two conditions at once, the cleanest route is a combined audience. In the combined audience builder, "Add audience to expand" adds an OR condition, "Add group to narrow" adds an AND condition, and exclusions remove people. Google's help lists a few limits:

• Up to 10 AND groups, and up to 100 conditions in total, in one combined audience.
• At least one included audience. A combined audience made only of exclusions is not allowed.
• Up to five combined audiences on a single line item.

Here is a typical persona. A home loan lender wants people house-hunting, not its existing borrowers. The combined audience could be (in-market for residential property OR in-market for home loans) AND (an affinity segment for business professionals), with the lender's own customer list added as an exclusion inside the same combined audience.

Every AND condition shrinks the pool. Google warns that a combined audience can end up with fewer than 1,000 users, and a campaign may not serve to an audience that small.

What does optimised targeting do to your audience choices?

Optimised targeting lets Google's system reach people beyond your chosen lists who look likely to click or convert. It works on display, video and audio line items that use automated bidding for clicks, conversions or custom bidding, and on Demand Gen line items. It is not available for connected TV line items or for the viewability bid strategies.

Two points matter. First, it can switch on without you asking. Google's help says display, video and audio line items get it switched on automatically when they use automated bidding and target affinity, in-market or custom audiences. Second, it changes what your audience choices mean. Location, language, placements, demographics on display, video and audio, brand safety and first-party exclusions stay as hard limits. Your included audiences become hints the model starts from, not boundaries it stays inside.

That suits a lead campaign judged on cost per lead. It does not suit a campaign where the client approved a specific audience and expects delivery to stay within it. Make the choice on purpose, and untick "Use optimised targeting" on the line item when strict targeting matters. If you want to know what the model actually does with your lists, read our explainer on how AI optimises programmatic advertising.

How narrow is too narrow?

An audience is too narrow when it cannot absorb your budget at a sensible frequency. Two quick formulas tell you:

• Impressions you can buy = budget ÷ CPM × 1,000
• People you need = impressions ÷ target frequency

Take an illustrative ₹5 lakh, four-week display campaign at a ₹100 CPM. That buys about 50 lakh impressions. At a frequency of five over the month, you need roughly 10 lakh people you can actually reach. If your layered audience across Pune and Mumbai holds only 2 lakh, the line item has two bad options: underspend, or show each person around 25 ads. Neither helps.

The fixes are simple. Remove the weakest layer, widen the geography, or split the budget so the narrow audience gets a small, capped line item and a broader one carries the rest.

Deals need extra care. Google's guidance on deals says audiences and demographics do not work well with them and can stop a deal from delivering, especially when the publisher passes few user IDs. On a Programmatic Guaranteed deal, keep audience layers light and let the publisher choice do the targeting.

What are the common audience targeting mistakes?

• Stacking every filter you can think of. Age, gender, three in-market segments, a custom list and five cities. Each layer looks sensible on its own. Together they starve delivery.
• Forgetting exclusions. Showing acquisition ads to last month's customers wastes money. Exclude converters and existing customers wherever you have the lists.
• Paying for data you don't need. Check whether a free Google segment does the same job before you add a data CPM.
• Judging too early. Google says automated bidding can take up to four weeks to learn. Give audience tests enough time and budget before you call a winner.
• Leaving optimised targeting on by accident. Check each line item before launch if strict targeting matters.
• Using one audience for every stage. A first-time prospect and a cart abandoner need different messages, caps and bids.
