Research suggests that, while it is possible to predict whether two people could enjoy spending time together in the short term, it’s (nearly) impossible to scientifically match two people for long-term compatibility.The strongest predictors of a good, functional relationship are how a couple interacts, and their ability to handle stress — two things that science says current dating website algorithms can't predict and online profiles can't demonstrate.“I think there is a possibility [that these algorithms] could evolve to better predict long-term compatibility.

It doesn’t help that these algorithms are closely guarded trade secrets.
The majority of the surveys, studies, and reports evaluating online dating sites’ efficacy are paid for by the companies themselves, leading to some possibility for biased results.
