What effect do these advertisements have on perceived importance of the advertised issue and attitudes and knowledge about the featured policy? Results from an online experiment studying the effect of online issue advertisements suggest that issue advertisements can increase the salience of and knowledge about an issue. Issue advertisements can also persuade about the merits of a policy but only among individuals without attachments to major political parties.
