Implementing Adobe Analytics to measure internal search result pages. Have a look at an implementation audit of ForRent.com Track search query (keywords) even when nothing has been found and shown on the page.
When you implement Adobe Analytics for internal search consider the following: 1. Capture search keywords. Trim and convert a value to lowercase. 2. Implement one custom event for # of searches, and another one for # of unsuccessful searches (when nothing has been found). This will provide insights as to what the visitors are looking for and what they can't find. 3. Capture # of search results and current page number.
