When to use automatic targeting

Targeting optimization works best for advertisers in any of the following situations:

• Find more customers
• Identify the best targeting to reach your most likely customers
• Increase reach without increasing bids or cost per customer

Automatic targeting results in new placements, so it's suitable for advertisers who don't have strict brand guidelines about where their ads appear. Keep in mind that you can still exclude placements from your ad group or campaign. It's not recommended, however—excluding placements can decrease the performance of your automatic targeting.

Types of automatic targeting

You can select from “conservative targeting” or “aggressive targeting” (known also as Display Campaign Optimizer). Both types can help you reach additional customers, but aggressive targeting applies more variations to your targeting. So if your keyword is “pens,” conservative targeting may extend to “felt-tip pens" and “ballpoint pens,” but aggressive targeting might show your ads in contexts related to “whiteboard markers” or “mechanical pencils”—if there’s data to suggest that those keywords will lead to conversions. Plus, automatic targeting works for remarketing.

Remarketing. If your remarketing list is for people visiting travel sites about Japan, conservative targeting may extend to people visiting sites about Tokyo tourist destinations. Aggressive targeting might go further, if the data supports it—it can expand independently of manual targeting based on predicted conversions.

Availability. Conservative targeting is available for all Display Network campaigns. Aggressive targeting is available for all Display Network campaigns with at least 15 conversions per month. This minimum is necessary because "aggressive" automatic targeting analyzes your campaign’s performance data to predict effective targeting, then to test and optimize it.

Conservative versus aggressive targeting. Aggressive targeting lets you reach more people than conservative targeting. The advantage of conservative over aggressive targeting is that, for a large majority of advertisers, it doesn't exceed your current cost per customer (or Target CPA, if that’s the bidding strategy you’re using). So conservative targeting can be a better option for advertisers on a fixed or limited budget, or for those who need to hit their cost-per-customer targets.

Here are general guidelines:

• Use conservative targeting when you want more conversions, but need to stay close to your current cost per customer (or Target CPA).
• Use aggressive targeting when you want to get as many conversions as possible, and are comfortable with some variation from your current cost per customer (or Target CPA/ROAS).

Smart display campaigns. Smart display campaigns, which are highly automated, use yet another type of automated targeting, combining contextual and audience-based targeting. They also automatically remarket to people who've recently visited your site and who are likely to convert.

Automatic enrollment

Display campaigns are automatically enrolled in conservative targeting, with the exception of Android app promotion campaigns (which default to aggressive targeting).
