Publications and white papers on online surveysWhat is an Intercept?An Intercept is essentially a mechanism that lets you automatically invite certain of your web site visitors to participate in online surveys. When a web site visitor is intercepted, an invitation message is displayed to the visitor directly in your web site (no redirection to another web site or popup is required). At this point, the web site visitor can either accept or refuse the invitation. See our demo intercept survey for an example. Intercepts can also be used to redirect visitors to any web page instead of permitting them to participate in an online survey. Using redirection, Intercepts can be used to invite users to participate in online contests and giving certain web site users special promotions. How can I setup an Intercept?The use of Intercepts involves a two step process. First, you must create the intercept using Interceptum and enter the intercept's properties described below. Second, you must integrate the Intercept in the pages of your web site from which you want to invite users to participate in online surveys. This involves adding a small piece of HTML code to your web site pages. Which Web Site Visitors get Intercepted?When using Intercepts, you generally do not want to invite or intercept all of your web site visitors. Intercepts offer three ways to control which web site visitors are invited: Frequency; Minimum Page Views; and Minimum Minutes on Site.FrequencyThe Frequency setting of an Intercept is a probability (0-100%) that the web site visitor will be intercepted on this page view. This probability is tested to determine if the web site visitor should be invited each time the web site visitor views a page of your web site.For example, a frequency of 20% means that a web site visitor has a 20% chance of being intercepted every time he views a web page on your site. Minimum Page ViewsThe Minimum Page Views setting of an Intercept defines how many web site pages the web site visitor must have viewed before he or she may be intercepted. Until the web site visitor has viewed the requisite minimum number of pages, he or she will not be intercepted. The Minimum Page Views setting is very useful to ensure that you do not intercept web site visitors who have just arrived on your site. Web site visitors who view multiple pages of your web site are more likely interested in your offerings and are more likely to participate in your online surveys. Minimum Minutes on SiteThe Minimum Minutes on Site setting of an Intercept defines how long a visitor must spend on the site before he or she may be intercepted.The Minimum Minutes on Site setting is very useful to ensure that you do not intercept web site visitors who have just arrived on your site. Web site visitors who spend more than a few minutes on your web site are more likely interested in your offerings and are more likely to participate in your online surveys. Will the same visitor be intercepted many times?The same web site visitor will only be invited once by an intercept during a certain time frame. By default, the visitor will not be reinvited before 30 says. A browser cookie is used in order to capture the fact that a visitor has already been intercepted. You can configure how many days must elapse before one of your web site visitors will be intercepted again.
