Like is simply a way of showing your appreciation towards a particular content on any of the social media websites available today. Although not all of them follow the system of likes and dislikes, Facebook is the frontrunner in this aspect and is largely responsible for the term gaining such widespread coverage and prominence in pop culture and the media at present. For advertisers and brands, likes take on an even special importance as the number of likes they receive periodically on their posts is a direct measure of the amount of social engagement they have with their customers or consumers. Also, your likes are hugely instrumental in calculating and designing the algorithm which decides and governs over the question of which posts will appear on your social media news feed.
