Infoset automatically puts a small customer satisfaction survey (CSAT) under each article you publish. Your visitors can rate your articles with a single click, so you can easily follow which articles are most beneficial and which are open to improvement.
You can see the number of times your articles are read and their CSAT ratings from the Articles page.
These measurements are not enough for you? You can integrate your help center with advanced 3rdparty analytics services (e.g. Google Analytics, Segment) and get more detailed analytics reports.
