If you get cold approaches on your POF profile on a regular basis you're doing great.

So far I have got several but have yet to come upon a single formula that gets them consistently. One of the keys is to generate new content on your profile from time to time. Different approaches appeal to different people, and changing it up keeps you interesting, especially if you're in a relatively small community like I am and the same people are seeing you instead of a vast spectrum of new people..
I just changed my profile on POF and am experimenting with a new approach strategy as well. Essentially, What I did was use the 4 questions they ask "Hobbies" "Goals" "Unique" and "Music" to make sensory based patterns linked to emotional states while answering the question.
1. What are your hobbies
I used a sensory based description of swimming to create states of comfort.
2. What are your goals/aspirations?
I used a goal of helping the world by becoming a great teacher of how to communicate with one another to create states of fascination.
3. What makes you unique?
I used the unique way I connect to other people to run something like an incredible connection pattern.
4. What is your taste in music?
I de-emphasized the usual genre-related answer in favor of talking about the passion of music to create states of passion.
For the "First Date" segment, I've had the best success with creating a very vivid sensory experience, doesnt matter what it is as long as it creates the right feelings.. Reading profiles gives you a great idea what kind of situations will fly with your local user base, around here, maybe 60% or more in some way say they love the outdoors, so I use that quite frequently and have had astounding results. When you're working with outdoor themes, it pays to utilize the seasons. Generally, even though people have a favorite season, when its cold you wish it was warmer and vice versa. Playing on a different season than the current one takes advantage of this, and also creates a sense of time distortion, making it seem like you've already been together for a while.
And my experimental approach involves writing a silly limerick for each profile I respond to, and being completely "Approach free" in wishing them success in recognizing when they've been contacted by someone who allows them to experience everything they are looking for.
If there is any interest I'll let you know how this approach works or does not.
