The difference between clicks and views are as follows:
Views - When someone views the detailed page of the listing whether it is on a different website or your own site.
Clicks (click through) - When someone clicks through to go back to the agents website, whether it is from a detailed view page or a search result, etc. If they are clicking to go back to the agent website, it counts as a click.
Sometimes a view and a click will be recorded if a visitor views the detailed information on a different website and then clicks through to go back to the agent's website.
