When tracking visitors using an image beacon instead of the JavaScript tracker, what are the differences? FAQ - General

When you are using an image beacon to track your visitors instead of the default fully featured JavaScript tracker, there are several data points of the visitors that won’t be tracked:

Referrers, including Search Engine Keyword, Referrer Website URL and Social network URL
Screen resolutions
Browser plugins
Page titles
Time in local user’s timezone
The image tracker code also does not create first party tracking cookies which results in some information being lost.
Files that were clicked and downloaded (Download)
Links to an outside domain that were clicked (Outlink)
Pages generation time (the time it takes for webpages to be generated by the webserver and then downloaded by the user)

Information that will be correctly tracked include:

User IP address
Date and time of the request
URL of the page being viewed (Page URL)
Location of the user: country, region, city, approximate latitude and longitude (Geolocation)
Main Language of the browser being used (Accept-Language header)
Browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model
