I've also been trying out this Plenty of Fish for a while as a little social experiment.

The good thing with POF is that you can see who's visited your profile, so you can accurately keep track visits per hour, rate of msgs per visit, and also the type of girls, whilst making modifications to your profile.
I've experimented with different taglines, pictures and profile descriptions of two extremes, about 1 month using each:

Description 1.
My self-summary
Welcome to my page and please leave a message after the
beep...

I'm awesome... no, seriously, I am. I'm about 60% awesome, 40%
sexy, and 20% ninja.

So let me tell you about some of the things that make me awesome...

I can make 30 minute pizzas in 25 minutes. I give real hugs
instead of those wimpy A-frame things people try to pass off as
hugs. I do sports, play guitar, cook, eat,party, go to gigs, travel -
simultaneously. I know how to recite the number pi up to 16 digits
from a sheet of paper. I know that the tooth fairy does not exist.
Finally, I can last longer than your ex in bed.

What I’m doing with my life
First off, I work for a large American company as a project engineer. I love my job, but it is JUST a job!

Second, I'm tired of the typical club scene and being asked
if I have any blow... guess I'm looking for someone who can break the
mould.

I’m really good at
Back rubs... and yes, I know what you're thinking. Get
your mind out of the gutter.

The first things people usually notice about me
That I have a face.

Favorite movies, shows, food etc
Stewie Griffin is my homeboy and nando’s is a gift from the
gods...seriously, I love it. AND I SWEAR TO GOD, IF YOU
SAY OTHERWISE, OR GO FOR ANY VEGGIE OPTIONS,
I WILL END YOU!!

The five things I could never do without
My phone (or pretty much mini computer), that little Men in Black zapper that makes people forget stuff (great if I go on a date I dont like), the key people in my life that are always loyal and there with me, NANDO’S, and of course....a sense of humour!

I spend a lot of time thinking about
stuff....and things....but mainly stuff

On a typical Friday night I am
smiling about one thing or another

The most private thing I’m willing to admit
I am looking for a good time and a few laughs. I'm not holding my breath, but I am looking for interesting conversation with someone that will not have to be quoted later on in a courtroom.

For our first date we should meet for a drink somewhere low key and public in case you are nuts P.S. No sex on a first date so don't even try it...

I’m looking for
• Girls who like guys
• Ages 19–34
• Near me
• Who are single
• For new friends, long-term dating, short-term dating

You should message me if

Description 2.
Hello, I'm Roger "The Dodger" Dodger. You see this profile? This is THE most impressive profile I've ever seen -- it's mine. It doesn't FIT on one screen, because it doesn't BELONG on one screen. I've carefully constructed my profile along psychological principles to weed out women whom most men don't want, and the result has been that I've been meeting some really incredible women who are genuinely attractive, intelligent, confident, and playful. Now, rather than refer to 30 years' worth of research found in academic journals on social psychology and behaviour modification, I'll just sit here all smug and sh*tand point out that if you read my profile and don't message or reply to the Dodger, it's because you're some combination of train wreck, stupid, insecure, and boring. True story.

Since the Dodger is aware that the vast majority of women on online-dating sites are meet-nobody attention whores who are here for only ego-propping, validation, and therapy (that includes YOU until proven otherwise, sugar lips!), I have only one small request: DO NOT MESSAGE THE DODGER OR REPLY TO THE DODGER IF YOU SUCKY DUCKY WHEN IT COMES TO A BATTLE OF WITS. After all, since I'm betting 50-to-1 that you are too timid, socially anxious, neurotic, and downright paranoid to get away from boring text on the computer screen and actually meet a flesh-and-blood person, your conversational skills had better be worth it. And I should warn you that even if you stand your ground in the battle of wits, sweetness, you'll be completely confused whether you want to kiss me passionately or slap me silly. Bang.

I'm smarter, more cunning, more challenging, and have more super powers than every woman on this site. I'm not for beginners, and if you are a beginner, I recommend gaining some entry-level experience with the illiterate knuckle-dragging mouth-breathers in my "Similar Users" box. Just look at them sitting down there like a panel of socially inept misfits and desperate virgins -- I wouldn't be surprised if at least one of them wants you to join him on his webcam so he can show you his junk and gag himself with a poopy-trailed pair of undies.

I'm a highly successful online dater, which I believe is the epitome of human accomplishment. I'm totally the complete package, and it turns out I'm the second most amazing man in the world. (Look, the ****es are constantly asking me about this, so I'll say it once and once only: The guy in first place lives in Paris, writes poetry, and tames white tigers. I think the asshat is a complete douche, a girly-man, but if that's your thing, then good luck to you. Go hop on a plane and enjoy your time in Paris with Fabio, OK? I don't care. I really don't.) [Edit: Now the ****es are saying that if I didn't care, I wouldn't devote any space to mentioning the French **stard. Think what you want.] [Edit: No, it hasn't been established that he's better in bed. What the hell? Why would you rely on hearsay and anecdotal evidence? This is starting to get on my nerves. The Dodger knows I can reduce any female body to a shuddering, trembling, back-arching, convulsing, Dodger-clawing mound of warm, sweaty, surrendering flesh -- even without the tantra techniques I picked up from all those slimeball e-books I read in between late-night porno sessions.]

I've found a better way of living. Shoot me a message, and if it seems we'd get along in some capacity, we'll go out there, make an awful lot of noise, and rock the **** out.

Some things I found

You can see my full profile here zebedee_a_333 travel, music, movies, food, sports, weekends

~I found highest frequency of profile visits occurred when using clear profile picture of me in a social environment such as a nightclub.
~Choose pictures that you look good in. (OBVIOUS)
~10's will rarely ever EVER message you first NO MATTER how sick your profile is.
~Description 1: Gets more girls opening you than description 2, hands down. Attracts a wide variety of girls but also LOTS of flaky ones.
~Description 2: Got less girls opening you that description 1, but the ones that do are much more likely to be submissive. Does a good job of weeding out time wasters and uggs. Girls unlikely to 'beat round the bush' when it comes to meeting or arranging to meet.
~Weired one and I'd be interested if anyone else experienced this. But I found local girls are more flaky when it comes to meeting than girls outside of my hometown. Maybe a social fear??
~Older girls are more likely to meet. Avoid 18-19 year olds who are on 'Just for chat'. They will waste your time.
~If you look good with your top off (no homo), you can use it in your profile but not as your main picture.
~Your tagline and first few lines of your description are 2nd and 3rd most important respectively behind your profile picture as they are shown on on search results. I found cocky funny taglines like 'what's the offside rule?' work best and also gives something for girls to open you with.
~Meeting is ten times more likely to happen after you've taken the conversation away from POF.com, such as exchanging numbers, or facebook.
~On a final note, don't get frustrated, seriously. Online gaming is not like the real world.
