The connection between two people is always different depending on the people, so there is no way to "guarantee" a strong connection.
However, you can do things to increase the likelihood of finding a better match. Getting off your screens to participate in the real world is an important one.
If you meet someone doing an activity you both love, it's a great start.
In addition, if you are both great communicators with a high EQ, you're more likely to make a relationship work.
But there is no "quick fix" for finding a partner who you can build a strong connection with.
