Audience expansion in Google Ads refers to a feature that allows advertisers to reach more potential customers beyond their targeted audience. This feature works by analyzing the existing campaign's performance and identifying additional audiences that have similar interests, demographics and behaviors.
The goal of audience expansion is to help advertisers increase their reach and exposure, ultimately driving more traffic and conversions to their website. By using this feature, advertisers can expand their target audience without having to create a new campaign or adjust their targeting settings.
Audience expansion uses machine learning technology to find and recommend new audiences that are likely to be interested in your products or services. This feature works by analyzing the performance data of your existing campaigns, looking at signals such as search queries, websites visited, and other online activities. Once the data is analyzed, Google Ads will identify additional audiences with similar interests, demographics and behaviors as your existing audience.
It's important to note that audience expansion is an opt-in feature and can be turned on or off at any time. Advertisers have full control over which audiences they want to expand to and can set limits on the level of expansion they want.
Overall, audience expansion is a powerful tool for advertisers looking to increase their presence in the market and attract new customers. With its machine learning algorithms, it allows advertisers to reach more potential customers without having to manually adjust their targeting settings or create new campaigns.
