Social Media advertising
This is a very direct way to target you customers. Unlike search engine marketing, in social media marketing you get the opportunity to lookup customers based on their preference. If you are selling some thing new or something only very few people search online and people are not going to specifically search for this online then social media advertising is your perfect approach. For example, brooches, which is an ornament fastened to clothing with a hinged pin.
Only few people search online for brooches. With social media advertising you can target people who are more likely to buy brooches by taking advantage of the look a like audience algorithm.
