The Most Hated Advertising Techniques described by Jakob Nielsen’s Alertbox:
- Pops-up in front of your window
- Loads slowly
- Tries to trick you into clicking on it
- Does not have a “Close” button
- Covers what you are trying to see
- Doesn’t say what it is for
- Moves content around
- Occupies most of the page
- Blinks on and off
- Floats across the screen
- Automatically plays sound
Conversely, users preferred ads that clearly:
- indicate what will happen if people click on them,
- relate to what people are doing online,
- identify themselves as advertisements,
- present information about what they are advertising, and
- provide additional information without having to leave the page.
