First thing’s first. If you are interested in a given person on an online dating site, you must first determine why are you interested in this person. Once you know that, it is going to be a lot easier to strike up a conversation with them and not come across as someone who simply will talk with anyone for a date opportunity.
Select members based on interests, hobbies, age rage, distance to where you are in relation to how much of a long distance relationship you are seeking, et cetera. Next you want to break the ice a little bit. You cannot catch a fish if there’s a foot thick sheet of ice covering the water, now can you?
Keep it simple. You do not have to make this person want to marry you immediately. Be kind and be respectful. Do not use a lot of abbreviations and slang and LOLs to attract this person. Try to talk as if you were standing right beside the person having approached them in a coffee house or a bar.
Say something interesting. There’s no reason why you cannot come up with a quick joke or an interesting tidbit about yourself, your life, your day or even tell them why you are interested. Be direct but keep a slight distance. Remember that even though you cannot see this person directly, they are a person just like you and have feelings as well. You don’t want to be rude or inconsiderate.
Strike up common interests or an inside joke together. Tell him or her something about yourself that is not in your profile to show them that you trust them and that you are interested in developing things past a “hello, how are you doing?” relationship. Once you have done this, the ball is going to be in the other person’s court.
If you have handled yourself well, and they are at all intrigued by you, then chances are you will get a very positive reaction. If not, do not pester them with messages or emails. They have the right to refusal, and if they said nothing the first times, chances are if they answer you the second time, it is not because they are interested in your profile. It is to tell you to go away.
