When you're using an automatic Instagram liker feature, you should try to be as specific and relevant with your likes as possible. This means that you should sit down with the Instagram auto liker app you're signed with and talk to them in detail about your target audience. This way, they can focus just on this demographic, and not waste their time elsewhere. The more specific you get with your target audience, the more likely they are to be interested in checking out your account in return. If they have nothing to do with your niche or industry, they may not return the favor.
