Let's have a title like: Magic Trick - Coins Trick - Magic Tricks - Coin Tricks then , will Google generate 4 sub-titls? like Magic Tricks Coins Trick Magic Tricks Coins Tricks or he will also rank me for "magic coins"?! you see that i put - between 4 keyword phrases
It depends on what content the web page has, titles matter too but mostly content inside web page matters.
This could potentially help you rank for every individual keyword and combinations/permutations of keywords like: Magic Trick Tricks Coins Coin Magic Trick Magic Tricks Coin Trick Coin Tricks Trick Coin Trick Coins Trick Magic Tricks Magic Magic Trick Coin Magic Trick Coins Magic Tricks Coin Magic Tricks Coins etc. However, I would probably organize multiple pages in a pyramid theme having one page I was trying to rank for "Magic Trick - Magic Tricks" and another child page that I was trying to rank for "Coin Trick - Coin Tricks - Magic Coin Trick - Magic Coin Tricks"...
