Need to track conversion on my online store

I have open an ecommerce store and I have almost setup my online store. I am not sure where to start advertising but I am starting with doing an outdoor advertising. I want my customers to track through conversion and for this I need someone expert help. Anyone advice me on this?

If you are doing online advertising, then most of the systems provide the ability to perform conversion tracking. Google analytics will do it out of the box, and things like Facebook ads also provide conversion tracking.

Tracking offline advertising is much harder unless you use some kind of identifier such as a discount code which is specific to a particular ad channel.
