How to find love and not just waste your time?

How to recognize a good dating platform to really find love and not just waste your time? There are so many different services now, but it is not always clear which of them really help you meet the right person. What should you pay attention to - selection algorithms, quality of profiles, availability of verified users? Maybe there are some signs by which you can immediately understand that the platform is focused on serious relationships and not just casual acquaintances? I would be glad to hear advice!
