What defines an Avenger?
Spider-Man can't be in the movie because the film rights to Spider-Man are owned by Sony, and the Avengers is a Disney movie. In the comics, Spider-Man has been an Avenger, but so have dozens of other characters, and there would hardly be room for all of them in a movie. (Various X-Men characters, like Beast, Quicksilver and the Scarlet Witch have a better claim to be Avengers than Spider-Man, but 20th Century Fox owns those rights.)
