Do you consider pop-up ads useful or annoying as a source of media to advertise products/services?

it's pretty clear that people like certain types of advertising very much. It just requires the marketers and the advertisers to stop thinking of advertising as a second class (or third class) type of content that needs to be forced on people. Instead, it's about recognizing that ads are content, and if it's good content, people will be willing to watch it (or even seek it out). However, it really does need to be good, relevant and non-intrusive.

Pop-up ads is a double-edged sword, it could be very useful when used in a manner that would not interrup the user experience, but very harmful if it's intrusive and negatively affect the user experience.

Many businesses think the route to increased readership is through pop-up ads. Pop-up ads are online ads that "pop up" in front of your website visitors. The pop-up ads actively engage your visitors, which is good, but the ads can also annoy them.

I consider them very annoying, and 65% of the ads i close them even without looking on the ad itself.
