I like that it provides me with analytics for each click, allowing us track how our ads are performing as well as which products they lead people too after clicking through from an ad or social media sharing link! There isn't much else at this time but if you're looking into shoestring budget advertising then use your imagination because there's so many ways in using both paid options (like AdWords) & organic sources of traffic/views such is Facebook Ads etc - we've been able t do very good targeting without having any extra funds available otherwise!! We can reach out audience who have engaged / visited specific pages when creating content around topics related thematically e g "shoes" vs more general topic areas where customers may be searching eg 'best shoe stores'.
