Going long here because a short answer really doesn't do this justice.
These algorithms are built to keep you engaged, not to find you a match. Understanding that changes your whole approach.
Things that have actually helped me:
- Short bios outperform long ones on swipe-based apps
- Responding quickly in the first 24 hours makes a measurable difference
- Niche platforms often outperform general ones for specific demographics
- Profile photos should feel natural, not heavily filtered
The one that stuck for me was Datedesire. I'd try it before paying for anything else.
Take what's useful and leave the rest. Every situation is a bit different.
