Yes, you don't rely just on Attraction, you need more than it. Comfort, qualification and building rapport.
Think of it this way: You see a girl, she's amazing looking. Got her high heels on, lovely dress, big tits being pushed all the way into her face, nice round ass, everything. She's hot and you want to talk to her(attraction). Then you talk to her... and what's this? She's really boring. Is that a turn on or a turn off? Turn off. You're a guy, you don't care though so you try it on anyway but she's got no personality. In this situation you're only going to give her more time and effort if she's clearly DTF.
Flip side: Average looking girl, you'd fuck her, decent tits, decent body, decent ass, everything. You start talking. Holy shit! This chick is really interesting! She's been all over the world, knows how to talk and speaks well and clear, she's really interesting! Turn on or turn off? Turn on! Shit, is this chick for real? Best move on... Holy crap! She has a personality to match. She's funny, can take a joke. Turn on! You want to fuck her more now than you did before.
See what i'm getting at here? Men and women are much the same with some slight but significant differences here and there and you can bet your bottom dollar all the PUA gurus know this! Hell, look at Strauss; the dude gave chicks the exact same "dating" advice he's been giving guys for years right down to Triangular gazing!
Step by step is pretty much this:
Approach/Opener(Attraction)
Mid-Game(Comfort/Qualification)
Closing(Seduction).
I wouldn't consider n-closing "closing." N-closing is mid-game.
Approaching/Opening should be built up on attraction which is having a neutral or higher level of attraction built up so they don't mind you physically being there talking to them.
Mid-Game is building up comfort and qualifying/having them qualify for you. After the pleasantries/introductions you start building up rapport, sharing stories, getting to know her and Demonstrating Higher Value without making it obvious("I've travelled a lot, met X, Y and Z and I know a lot of people", etc., etc.)
Closing is basically having built up comfort, qualification(DHV) and attraction(All three are essential) then phase-shifting and letting her know subtly/through body language that you're attracted to her and want to fuck or kiss her(Kino escalate, get closer and more intimate, focusing on her eyes and lips more actively).
Throughout the conversation you should be able to gauge whether or not she's into you. All of the tricks or techniques you'll play in your meeting are basically to rise her interest in you, get her attached to you and for you to gauge her level of interest, whether or not she'll allow you to kiss her or take her home. For example "bouncing" with a girl is basically a form of compliance and a huge IOI of her level of interest in you. She doesn't have to go with you, she chooses to go with you(IOI). You grab her by the hand and lead(DHV) her, she doesn't shy away and holds back(IOI). You isolate her, she smiles, laughs and enjoys being alone with you(IOI). PHASE SHIFT!! Mr.Seduction comes out to play, gives her the "I want to fuck you" look, escalates kino, looks into her eyes and applies Style's Triangular Gaze technique to let her know you want to kiss her. Boom, go in for it.
Anything after Isolation is basically overkill if you want to k-close a girl. If she goes with you out alone and enjoys your conversation she's interested in you. If she's hesitant at first her level of interest is neutral but she's interested enough to let you try convince her you're something she can't miss out on.
