Current Campaign

Explore my recent Google Ads campaigns:

Before optimization: The client struggled with Google Merchant policies and careless guesswork, experiencing a low CTR of 4.67k clicks over a year. My analysis identified opportunities for improvements.

After optimization: Implemented a new Shopping Ads campaign using Performance Max bidding and improved assets for the campaigns, which spans Google Search, Display, Discover, YouTube, and Shopping Ads. This strategy increased visibility and achieved a significant CTR improvement within a month.

Results show a considerable increase in clicks and conversions, with further enhancements underway through advanced keyword and conversion tracking. The current daily budget for the above campaigns is $3.5.
