Indeed, as we all know that first chats are much like the first dates, and we have only a few chances to impress her on the very first chat. As many say, “First Impression is The Best Impression”. Thus, it’s much important to chat or say something like to take away the first time and most feel that you are annoying her for the very first time when making the first conversation.
Never think that girls get impressed by bike stunts, leather jackets, macho looks n funky hairstyles. While choosing their partner girls to think about a long-term relationship which will lead to marriage so your behavior is more important than your looks.
Yet as you have asked me, I would try and lay down some basics for you.
Even if you are in a down phase in life, do not impress upon her that you are jittery from inside. Show her you have hopes to overcome whatever problems you are facing. Assuming it’s your initial talks or meetings, this is important.
Do not hide anything (if you have any skeletons in your closet).
Give them the gift of trust. It need not be done in the first few meetings but needs to be done when you are still in the acquaintance phase or at least when she considers you an acquaintance only, then during that time itself.
Do not judge her to her face till it’s not something that hampers your personal deep beliefs or your dignity (read: if she abuses you or someone else ), do not tell her to her face, what you think, about some of her actions or opinions and how they show what she is like (if your opinion is negative).
Have some ambition. 
Have some ambition which you are actually in the process of making come true.. or at least are trying to achieve it. Your ambition need not be something big only, it need not make you a billionaire. But you need to have goals in life towards which you are working. So, that you can provide for her basic needs at least (not that girls these days need to be provided, but that if you can provide for her, you are up to or one step ahead than other ‘suitors’). Just don’t be aimless.
I do not mean that you spend heaps of bucks on clothing, but besides not dressing up in tatters, of course, have your clothes ironed, especially on the first few meetings. Pay attention to your shoes too. Think about how she dresses. If she is flamboyant, you should look flamboyant. If that is not your style, then at least choose some accessory in you that looks flamboyant eg: goggles, watch, shoes, etc. (Choose those which might not cost you much, if you do not want to spend that much money, but which still look trendy). If she is more into simple or regular clothing, it would be advisable you tone down your flamboyancy. So, it’s pretty dependent on what or how she likes her dream boy to look as, in the initial phase.
Discuss what interests her
If she is into some hobby, search for some current news about it and discuss that with her. Say, she likes painting, see if there is an exhibition in town and take her there or discuss it. If she is into singing or music, ask about her favorite singers and gift her their albums, or look up if some band performs in town and take her there. If you both have some interest in common, it’s even better. You can discuss things on phone even and impress her with your knowledge about what she likes. This works even if she is a Science geek, though if you are not, you would need to do a bit more “homework”. Don’t be afraid to state some facts wrong (mistakenly)though, it’s not about that. If she corrects you, don’t be embarrassed, just say that you had forgotten. This would show her you are open to accepting your wrongs if you are, gracefully, without fuss.
Smile and don’t fidget like you have got a shock. She might not like to have all eyes on her if you faint. A bit of fidgeting is ok but keep it in control. And yes smile. Don’t sit there like a dummy without any expressions. But don’t smile like a lunatic either, that is the other extremity.
Sense of Humor
Everyone loves a good laugh and most girls are attracted to guys with a great sense of humor. If you’re thinking about how to impress girls, always keep in mind that a great sense of humor is the basics of any relationship. Girls would groove on the fact that you can be cheerful and being able to laugh at yourself. Drink in the art of throwing in humor even during the hardest situations; this will change the way how girls look at you.
Be Honest
Never lie about your appearance, what you have come through or where you live. Girls are not into trivial things, such as money or appearance. Rather, they are very much moved by the honesty and genuineness that appears to get down the chat window through your words.
Find a way to compliment her
Don’t compliment her all the time, because it will become obvious that you’re really into her. But try to give her at least one nice compliment. If it’s done in the right way, it’s guaranteed that she’ll remember the compliment, and remember you as well. If you’re confident, give her a compliment about her.
Impress her with your brains
Act smarter and more mature than those other idiots. But don’t come off as a geek or nerd. If you want to impress her, be interested in her, find her fascinating, listen to her, and encourage her to tell you what her opinion is about things, value her input and show sincere respect for her as a person. Do this.
Make her feel comfortable around you
Make sure that she knows that she can come to you with any problems that she might be having in her life. Also, make sure that she knows that not only can you listen to her problems, but you can also solve her problems, or maybe at least just come up with ideas to help her solve them. Be warned, however. Offering advice is one thing, but girls don’t talk about their problems to someone because they want that person to try and solve them all. They want someone who will listen, first and foremost.
Lastly, It doesn’t matter to a girl how attractive your pickup lines or cheesy gestures are. If you have an attitude and booming personality. she will notice you without effort. And that’s where you impress her the most
