Remarketing Campaigns
Google as well as Facebook offer excellent remarketing and dynamic remarketing opportunities. As mentioned, remarketing is quite useful for industries where the purchase decision isn’t based on impulse. As a result, we see it working in B2B fields, education, health, automotive, hospitality and travel, real estate and shopping.
So remarketing depends on the nature of your business - your sales cycle, conversions goals (e-commerce vs lead generation) and list segmentation and creation. This last part is very important because you have to be careful not to double-serve because this will annoy customers instead of gently nudging them to your solution.
Just to give you an idea, compared to Search and Display, Remarketing campaigns have a 20% lower conversion cost, thus delivering better ROI for your advertising effort.
