Before taking the course, we were concerned about the inconsistent leads we were generating. We also worked with third-party vendors, but the results were unpredictable and lacked accountability. Additionally, I struggled to comprehend the metrics and analytics behind social media marketing. However, after attending the 'Run Successful Google Search Engine Marketing (SEM) Campaigns for PPC and Display Ads' course, I learned how to effectively set up leads and discovered that using different creatives could achieve better cost per result. This knowledge enabled me to generate three times the number of leads at one-third of the previous cost.
