Similar to Audiences / Advertising Terms Similar to Audiences Similar to Audiences is a type of audience targeting available in digital advertising platforms like Google Ads. It allows advertisers to reach new users who share characteristics or behaviours with an existing audience segment, such as past converters, website visitors or email subscribers. These audiences are automatically generated using data from your remarketing lists and are designed to expand your reach to people who are more likely to be interested in your offerings. The platform analyzes signals like search behaviour, site activity and engagement patterns to identify users with profiles that resemble those of your original audience. For example, if you have a remarketing list of users who donated to your nonprofit or bought a product from your store, the “similar to” audience will include people who exhibit online behaviours that align with that group. This predictive targeting increases the chances of reaching users who are likely to convert, even if they have never interacted with your brand before. Using “similar to” audiences can help scale your campaigns while maintaining relevance. They work best when combined with strong creative, clear calls to action and well-defined goals. Because they are based on actual user data, these audiences often outperform broader interest or demographic targeting. It is important to monitor performance and refine your base lists over time to improve accuracy and impact. Whether your goal is to increase donations, acquire leads or drive sales, “similar to” audiences offer a strategic way to grow reach without sacrificing audience quality.
