192 USD Targeting ophthalmic surgeon Local business
Social Media Advertising
Task: Reduce the cost per lead and find a stable source of patients in a competitive niche.
Challenges:
Technical: The client's business account was blocked due to numerous Facebook bugs, making ad launch impossible.
…
Marketing: Lack of understanding of which audience is the most effective and profitable.
Solution (step by step):
→ Technical recovery: Successfully resolved all verification and access rights issues, unblocking the ability to run ads.
→ A/B Testing: Launched simultaneous testing of two key audiences: "Patients 60+" and "Their adult children 35-55".
→ Analysis and optimization: Data showed that the "Children" audience generates leads three times cheaper. The unprofitable audience was immediately turned off, and 100% of the budget was redirected to the winner.
Results:
Achieved: More than 40 qualified leads during the testing period.
ROI: Found a profitable and scalable patient acquisition channel.

147 USD Successful unlocking of Google Merchant Center after blocking
Contextual AdvertisingOf course. Here is a brief and expert description of this case for a portfolio, written from a male perspective.
Project Title:
Successful Unblocking of Google Merchant Center ("Misleading Information")
…
Description:
A client approached me with a fully blocked Google Merchant Center account due to a critical violation of "Misleading Information." The situation was complicated by the fact that their self-appeal had already been rejected by Google.
I conducted an in-depth technical audit of the website and data feed, identified the root causes of the violation (discrepancies in return policies, contact information, and prices), and provided the client with a clear correction plan.
After implementing all the corrections, I prepared and submitted a new, well-argued appeal, explaining the technical error in detail and demonstrating the work done.
Result: The account was successfully unblocked within 5 days, allowing the client to resume product ad displays and avoid losing a key sales channel.
Tools: Google Merchant Center, Google Ads, Google Analytics.
