As advised, post pics of yourself. Try to have at least one "with a group". You're a guy and women want social guys, so don't look like the Lone Stranger.

Be sure to read the prospects profile (if they created one), and start the convo out by asking them about something you read in it.

Use open-ended questions and not Yes/No to avoid you throwing your back out from having to carry the convo all by yourself.
If all replies (if you get any) are simple, could-care-less single-syllable replies.. well that's on you to really want to carry that weight and waste time continuing.

If they have absolutely nothing in their profile except "I'll tell you later"... again, that's on you to waste your time continuing. But conventional wisdom is that if the prospect can't put 20mins effort into creating an elevator-pitch profile to attract a date - they won't put any effort into a successful dating relationship with you. Move on.
