I'm a photographer & own a photo studio. I offer my "services" on my website and folks can purchase their shoots from there. Is that considered "Lead generation" or "E-commerce" when I'm setting up the campaigns. And, how can I specifically target the actually "click" to a specific sale? I have the same questions for a DaySpa that my wife owns, and we are now doing ads for it. Is it lead gen or e-commerce when clients are booking their services from the site?
