Googleâs free website traffic analysis system (Google Analytics) that gives a huge volume of information about your siteâs traffic, who comes there, how long they stay, where they go on the site.
Do they perform any âgoalsâ that you/we determine (like use a contact form or a quote form).
In short, if a web visitor does whatever you decide is the goal of your site, it can count as a âconversionâ.
While the service is free, getting your website set up on GA is important, and having someone whoâs extremely familiar with it is important to getting started.
