Custom Audiences<\/a> that don\u2019t contain any information regarding the value of the users.<\/span><\/p>\nIf you haven\u2019t created your Custom Audience yet which you would like to use as a source audience, you can also click on Create New Source and choose between Custom Audience and Custom Audience with LTV.\u00a0<\/span><\/p>\n<\/p>\n
Once you click on any of it, you will be taken to the window where you can create a new Custom Audience with LTV or without it.<\/span><\/p>\n<\/span>Audience Location for creating Lookalike Audiences<\/span><\/span><\/h3>\nAs for the location of the Lookalike Audiences you can only choose countries, so neither any regions nor cities can be chosen.\u00a0<\/span><\/p>\nAlthough if you want to only target a city with a Lookalike Audience, you can also do that easily. Just simply choose the country where the city is located, and in the ad set creating process, limit the targeting to that city only.<\/span><\/p>\nHowever, you have the option to add multiple countries for a Lookalike Audience. This is especially useful if you are targeting multiple smaller countries and the source audience size would not be big enough to be very useful for Facebook. (less than 500 users).<\/span><\/p>\n<\/span>Select Audience Size for Facebook Lookalike<\/span><\/span><\/h3>\nThe last thing you have to do is to define the size of your Facebook Lookalike Audience.<\/span><\/p>\nFirst, you have to define how many Lookalike Audiences you would like to create from the audience source you have defined above. You can save time if you create all of the LLAs at once or you can create them separately. (then the whole process has to be repeated).<\/span><\/p>\nThen you can use the slider to create the size of the LLAs. The best practice is to create audiences with similar size as when you are creating separate ad sets from these a more consistent performance can be expected if the audiences have similar a similar size.<\/span><\/p>\n<\/p>\n
Facebook will also share with you the estimated size of the Lookalike Audiences you would create. As you can see, in this case the size of the 5 Lookalike audience we have created from American and British users is estimated to be 5.68 million people per Lookalike Audience.<\/span><\/p>\nThese are very large audiences, so additional gender or age targeting could be added at the ad set level when you would set up the FB campaigns with these LAAs.<\/span><\/p>\n
