Experience

  • Post BigQuery Data on Facebook Marketing API
    https://victor-paulillo.medium.com/post-bigquery-data-on-facebook-marketing-api-276516566bbe

    This project connects BigQuery with Facebook Marketing API.

    The article shows a simplified version of the project and shows how to post data on Facebook Ads that can be used to build audiences for ad targeting or to set as an offline conversion.

    Upon completion of the project, it was possible to dive deep into customer analytics and machine learning models to improve advertisement performances and new marketing strategies involving Facebook Ads.

    Offline conversions enable Facebook machine learning to better understand who is the best customer of your company, especially when you have products and services that aren’t distributed online.
