Are you using Google Analytics?
Yes I have setup analytics but is there any specific way to identify conversions.
@kevinsaptel - Tracking conversions means tracking the source, then a desired action. If you advertise a specific landing page, then you could track that as an entrance, and everything that happens after a visitor hit your landing page. If you just advertise domain.com then you can’t track, unless the only way that someone would come across the domain was via a specific campaign.
Unless you provide specifics, I am not sure anyone could provide more guidance.
