# 1 is the Loneliest Number

Behavioral Marketing Campaigns don't need to be limited to one type of behavioral targeting. Revenue Science explains three different types of targeting that can be used separately or combined depending on the advertiser's strategy.

Inventory Extension

Inventory extension allows advertisers to extend their inventory outside a specific section of a site, still most common among finance, automotive and technology advertisers. Inventory extension behavioral targeting is often used when an advertiser is buying upfront or in bulk.

Life Stage Targeting

Mentioned in a previous behavioral targeting post, life stage targeting allows advertisers to target consumers who are going through life altering events such as becoming a parent or buying a house. These consumers usually spend a decent amount of time shopping online before making a purchase therefore advertisers can easily target them based on their previous shopping behaviors.

Behavioral Search Retargeting

Search Retargeting works where consumers clicked on your search ad but didn't convert. Then advertisers can go and retarget them with ads on a network of sites. Here, the advertiser only gets charged if the consumer clicks on the ad.

Some of these strategies can lead to successful campaigns when used independently but there are also strategies that can lead to more effective campaigns if more than one type of behavioral targeting is used.
