Tag Management: How to Monitor & Improve Site Performance
There are hundreds of services for site tracking, advertising, customization, and, in general, souping up your ability to measure, reach, and convert your visitors.
Most services rely on JavaScript to track the activity of visitors on your website and report on—or respond to—their behavior.
When people talk about “tags,” they’re talking about snippets of JavaScript provided by third-party services like Google Analytics, AdRoll, Adobe Analytics, etc.
Each tool can improve your ability to reach and serve customers, but it also means adding a new piece of JavaScript (i.e. a tag) to your site.
