Startup Idea: Facebook Ad Analytics Tool

Startup idea to develop a software tool that efficiently retrieves information about Facebook ads based on user-input keywords, display period, and ad type. The tool will show metrics like shares, likes, and clicks. It's intended to increase work efficiency by saving users time spent on manual search.

I want to know which ads on Facebook generated the most shares, likes and clicks. I waste considerable time searching Facebook to learn this information. I wish I had a tool that allowed me to type in keywords for ads, display period, and type of ad and that then returned those ads for me to review. That would help me to do a better job at my work and to be more efficient. I would be willing to pay a flat fee for the tool and a periodic update fee.
