I am currently managing a Hotel website that commonly have the option for any visitor to select the following: · Check-in Date · Check-out Date · Number of Adult · Number of Child I been given an assignment to capture the above information so that later I can view the report or even advertise in Google Adwords from the Remarketing List that match the criteria. First, am I able to set as display by adding secondary Custom Dimension (Or Custom Variable or User Defined Value) with Check-in Date & Check-out Date or more such as Number of Adult more than 2? If above is possible, what is the best practices to choose as option such as below: Custom · Custom Variable · User Defined Value Custom Dimensions · Custom Metrics · Calculated Metrics Audience Definitions · Audiences · Dynamic Attributes It must be able to be advertise campaign by linked with Google Adwords for Remarketing List purposes as example if any visitor searching for room availability of next month, as the current date is not past the period of Check-in Date & Check-out Date captured as above (and Number of Adult & Child). Anyone knows how to create above setting are welcome to propose the project fees and it requires to setup in both Google Analytics & Google Adwords account by guiding (not setting by granting access) There is an attachment as sample to be referred so try to understand it follow by posting it for bidding.
