Can advertisers target users based on their job title responsibilities?

Yes, it is possible for advertisers to target users based on their job title responsibilities using Twitter Ads. This can be done through the use of LinkedIn's professional audience targeting options, which allow you to target users based on their job function, seniority, and company size, among other factors.

For example, if you want to target users who have job responsibilities related to marketing, you could use LinkedIn's job function targeting option to reach users who have job titles such as "Marketing Manager," "Marketing Director," or "Chief Marketing Officer." You could also use LinkedIn's seniority targeting option to reach users who have a high level of seniority within their organization, such as "Executive" or "VP."

It's important to note that LinkedIn's professional audience targeting options are only available for certain types of Twitter Ads campaigns, such as Promoted Tweets and Promoted Accounts. They are not available for all types of Twitter Ads campaigns, such as Twitter Ads for video views or website clicks.

I hope this helps! Let me know if you have any other questions.
