I've tried internet dating but the girls often stop emailing me after a few messages.
There might be no chemistry in some of the cases, but is there anything I can do (or avoid doing) that can keep things going and improve the odds of meeting face-to-face?

If you're meeting girls from off dating site then chances are you are NOT the only male suitor that has come knocking on her email address, so you have to stick out of the crowd. Wow her right off the bat with correct spelling and display of knowledge and depth. A good medium length kept light conversation wise will keep her interested, no wall of text describing your life starting in the womb but no "Hey, hit me up" either. Jonlife hit it right on the head with his comment; girls love to talk about themselves and if you're a willing and active listener then they'll thrive off the attention.
Also after the first two emails or so try and move the conversation to another medium. AIM is a good tool for quick and easy conversation which most people have and it's much less work than emailing back and forth- and also gives the opportunity to touch upon many different subjects rather than go into nauseating depth trying to stretch out one via email. From there subtlely ask if she'd be comfortable talking on the phone; hearing each other's voices can simulate the senses and make you stand out in her mind plus it's a good way to test the waters on whether or not she's looking for something with a bit more commitment then just online (most girls won't just give their phone number to anyone). Though you also have to have the taste to know when it's a lost cause. If after 15 or so emails or over two weeks and she doesn't seem interested in contacting out of email she most likely isn't interested.1
