Conventional advertising is the main types of advertising that have been done in the past.

This includes newspapers, magazines, radio, TV and billboards

Alternative advertising is the same as guerrilla advertising. It's unconventional and unexpected.

It can be anything from street teams, to car wraps, to promotional exhibits, to postering blitzes. Basically, it can be anything you want it to be. There are no limits and many agencies create custom campaigns.

Nowadays, people like to take conventional advertising (TV, magazine, radio, out of home, newspaper, etc) and revamp them to create cool guerrilla marketing tactics.

Guerrilla advertising can also be called non-conventional advertising, guerrilla advertising, ambient advertising, and viral advertising.
