Pop-ups that Provide Hits...
Pop-up advertising is a method where, by using the main site's software, another site opens in a new window when the visitor clicks anywhere on the site. In this way, pop-up ads that provide artificial hits serve to lower the Alexa ranking of the advertised site. This advertising model, which also temporarily increases the Google search result ranking, is not a preferred advertising model by Google.
Pop-ups that Cause Loss of Trust Reduce On-Site Traffic.
Since visitors react negatively to involuntarily opened sites, both the site providing and the site publishing the pop-up ad experience a loss of trust. On-site traffic decreases, and hits drop. Additionally, as Google scores based on the time spent on the site, it quickly understands that the site is being abandoned and flags the site as fraudulent, lowering its trust score.
