When people take the time to give a compliment, it typically is received positively by the other person because it is acknowledging something great about them and is a way to express admiration. I would say that most of the time, compliments are a good thing and can definitely be used to build attraction because most people feel good when someone gives them a compliment. People tend to become attracted to those who give them a good feeling about themselves. So the short answer is, yes–compliments can absolutely help in building attraction. However, there are definitely instances in which it might have little to no effect on someone or maybe even have the opposite effect.
If someone receives a compliment from someone who they do not think too highly of or don’t really like, then the person might not even care so much about it or might actually be annoyed by it. I say annoyed because if the person feels that the other is saying it to express interest and the interest is not mutual, then the compliment will not be viewed in a positive light. In these type of scenarios, I would say that it is not really worth going out of your way to compliment the person and that it is important to find other ways to build a genuine connection or perhaps find someone whom you naturally connect with instead of trying to impress someone who is not that into you from the start.
In addition, people who are used to hearing the same compliments throughout their lives might feel indifferent towards a compliment because it is nothing new to them. For example, if someone is a talented musician, telling them this does not hold too much value because they might already know this to be the case or they just hear it all the time so it is not very special to them. On the other hand, if you find a way to validate the person for something that people don’t comment on all the time, then your compliment will go a long way.
Overall, compliments are definitely a good thing and can be used as a way to signal interest in someone but keep in mind that sometimes a compliment simply is just a compliment–so one should not read too into it and just take it at face value. If one is trying to use this technique as a way to get someone interested in them, it is important to not rely on this tactic alone and to find other ways to create natural attraction. I always like to remind people that what works on one person might not work as successfully on someone else so it is important to make an effort to get to know someone on a deeper level in order to really understand someone’s likes and dislikes.
