Web bug[Wikipedia article]
A web bug is an object that is embedded in a web page or email and is usually invisible to the user but allows checking that a user has viewed the page or email. Common uses are email tracking and page tagging for Web analytics. Alternative names are web beacon, tracking bug, tag, or page tag. Common names for web bugs implemented through an embedded image include tracking pixel, pixel tag, 1×1 gif, and clear gif. When implemented using JavaScript, they may be called JavaScript tags.
Web bugging is the use of these techniques, analogous to conventional bugging, though not as invasive or intrusive. The distinction of a web bug should not be confused with the more benign web spider nor the more malicious, nefarious or subversive devices such as computer worms.
Overview
A web bug is any one of a number of techniques used to track who is reading a web page or email, when, and from what computer. They can also be used to see if an email was read or forwarded to someone else, or if a web page was copied to another website. The first web bugs were small images.
Some emails and web pages are not wholly self-contained. They may refer to content on another server, rather than including the content directly. When an email client or web browser prepares such an email or web page for display, it ordinarily sends a request to the server to send the additional content.
These requests typically include the IP address of the requesting computer, the time the content was requested, the type of web browser that made the request, and the existence of cookies previously set by that server. The server can store all of this information, and associate it with a unique tracking token attached to the content request.
On web pages
Web bugs are typically used by third parties to monitor the activity of customers at a site.
As an example of the way web bugs can make user logging easier, consider a company that owns a network of sites. This company may have a network that requires all images to be stored on one host computer while the pages themselves are stored elsewhere. They could use web bugs in order to count and recognize users traveling around the different servers on the network. Rather than gathering statistics and managing cookies on all their servers separately, they can use web bugs to keep them all together.
Tracking on web pages can be disabled using a number of techniques.
Turning off a browser's cookies can prevent some web bugs from tracking a customer's specific activity. The web site logs will still record a page request from the customer's IP address, but unique information associated with a cookie cannot be recorded. However, web site server techniques that do not use cookies can be employed to help track a site's cookie-blocking users. For example, a web site can identify a request from a new visitor and send that visitor links that pass a unique ID as a GET parameter.
Browser add-ons and extensions can be used. For example, the Ghostery add-on analyzes JavaScript to detect trackers, web bugs, pixels, and beacons.
In email
Web bugs are frequently used in email marketing as a way of determining which recipients open the email. Doing this allows marketers to know who has seen the promotion or announcement that they have sent, and allows them to back-off or re-engage appropriately.
Some web bugs tracking in email can be disabled by:
Turning off HTML display and displaying only the text.
Turning off the display of images while still using HTML.
Implementation
Originally, a web bug was a small (usually 1×1 pixel) transparent GIF or PNG image (or an image of the same color as the background) that was embedded in an HTML page, usually a page on the web or the content of an email. Modern web bugs also use the HTML IFrame, style, script, input link, embed, object, and other tags to track usage. Whenever the user opens the page with a graphical browser or email reader, the image or other information is downloaded.
