Automatic liking is when an Instagram auto liker app likes other people's content on your behalf in order to try and boost your brand's credibility online. There are many Instagram auto liker apps out there that offer this as a feature, including the brands you see above. A lot of the time, they will also offer other engagement features as well, so you can benefit from them all. There aren't that many brands out there that just offer automatic likes for your Instagram – they usually come with comments and follows, too.
