Will depend on age group, where you meet them and what kind of personality they have, level of confidence they have. If dating online you have crap chances as odds are stacked against you. Got to be a real looker and have some interesting pics, outgoing, confident, look fun to be around, tall, abs, the generic stereotypes I'd say work pretty well. This stuff can be faked to some extent to get the date.
A not so pretty chick will get a confidence boost from friends commenting on pictures and dudes will hit them up in droves inflating what they can actually handle, usually ending with them finding someone too experienced and having baggage they can't handle. These girls generally are hopeless and can't maintain a lasting relationship. The type of girls "good guys" tend to be attracted to.
The thing about online dating, women and men have different views on attractiveness. For men its more of a bell curve whereas for women its a downwards slope. Meaning women online wont really want to talk to you unless your at least a 7+ on their scale, whereas they can be a 4 and have 20 dudes hit them up. About 3-4% of all profiles for men are seen as attractable to women. All of this is mostly judged by pictures. Game the system learn photoshop, shit works. For guys online meeting another dude for a date or mess around is easier if that is something you are into. You might of experienced this already, dudes will hit you up way more than girls online.
If in person girls are these days are much more timid especially if they are in a younger generation, id say maybe 18-29. They don't know the world before internet. Going to mall to dress to impress and picking up to find a potential match or being approached at a club. Lot of this goes against norms. Generally they aren't all that used to being approached and are on guard, I think maybe cause they just aren't used to it in person but more being surrounded online and have a safe space. Girls like this it easier to befriend and make a move sooner rather than later once you've entered a safe space.
Older girls, 29-44 are much easier to approach. Can just be up front with most of these girls and let them know. They for the most party have plenty experience and know what they want at this point. Most are out of party phase and looking for stable relationships.
For dating in general its all about lasting impressions. Give them something that makes them feel comfortable, make them laugh, be pleasant to be around, smell nice, look decent. Once they are in a comfort zone make your move, can be spontaneous or formal. Make a lasting impression and move to the next. Goal is to get them to view you differently than you would view a friend. If you stand stagnant too long you get caught up in the friendzone. Your aim here is for association with your actions when they think about you.
Not true for everyone but think of a song you like that has another meaning to it, might bring back a memory or something you were doing while listening to it. Maybe with someone, and bring up memories of chilling with friends or ex. You want that same association going on anytime she is alone and thinking about what your up to. This is what I mean by a lasting impression. Usually easy to do, can be subtle like singing in a car. Or more intimate like a kiss. Just have to keep building on it, eventually it will build up into a strong emotion, get to a point of where they are constantly thinking of you. All of this is just deconstruction of prior relationships though, there probably other ways of doing it, more of a logical way that it makes since for me on how to approach a potential relationship.
