We are uploading tailored audiences into the Twitter ads platform and adding them to campaigns. In those campaigns, only about 1/3 of those Tailored Audiences are getting targeted. Is there a specific reason as to why this is happening? We are uploading audiences that have over 200,000 usernames and we are only seeing around 60,000 of those users being targeted according to the analytics.
Additionally, when choosing targeted audiences, we are choosing a location in parallel with our tailored audience uploads and we are seeing still lower volumes of targeting during those campaigns. Does adding tailored audiences lower the overall volume of Twitter users targeted?
