I don't have the truth about online dating sites, but can offer insight based on my experience.
- Where you are will dictate success. If there are more attractive women competing, this helps your odds. This is obvious. The converse is also true. If there are either a lot of dudes, or a lot of ugly women, it will be harder in general.
- women with a lot of options stay interested for a very short time. Its on the span of days. If a women wants to date after a week, she has a high interest level. This seems rare.
- Men where I live set the bar low. If the bar is low, this will make women incredulous about dating or not engage on dating sites regardless how you come off.
- Women love to get free things and will often go out just to get a free meal. They might not talk to you again.
- Women will lose interest immediately if you don't fit certain characteristics. If they are primarily interesting in attraction, height is an issue. Other times, they want a recycled version of the guys she dated in the past. This person can be a normal dude, more of the cheating type. Doesn't matter.
- If you can be funny, your odds are much better. Boring conversations often lead to luke warm dates. Good conversations lead to better dates.
