What is the best marketing campaign which assisted you in making a purchase decision for the product and service offered.?

Marketing Campaign which is visually strong enough  to imprint a impression on my mind, whether done on social media /web ads, tv or print media is good enough to be sold out. 

The product/ service offered should cover my needs and should be comparatively better, being placed and promoted, i will definitely make my decision to get it. moreover it has to be within limits of my purchasing power.

Social Media Content and Ads are very effects for a purchase decision for the product and service offered

Appearing corporate at all times is key in all organization, but the type of duties carried out by employees is a factor.

Combining Content Marketing with Performance (retargetting via SEM or lead generation via email marketing) is a great mix.

It depends on the product / service and the market.
