<p>A tracking pixel, is one of various techniques used on web pages or email, to unobtrusively (usually invisibly) allow checking that a user has accessed some content. Common uses are email tracking and page tagging for web analytics. Alternative names are <code>web beacon</code>, <code>web bug</code>, <code>tracking bug</code>, <code>tag</code>, or <code>page tag</code>, <code>pixel tag</code>, <code>1×1 gif</code>, and <code>clear gif</code>. When implemented using JavaScript, they may be called JavaScript tags [<a href="https://w2.eff.org/Privacy/Marketing/web_bug.html">1</a>]</p>
<p>There is a work in progress to standardize an interface that web developers can use to asynchronously transfer small HTTP data from the User Agent to a web server that call it simply beacons (in the context of web development) which can be used to send data to a web server prior to the loading of the document without delaying the load and affecting the perception of page load performance for the next navigation [<a href="http://www.w3.org/TR/beacon/">2</a>].</p>
