What Is a Tag?

A tag is a piece of code used to send information to a marketing or analytics platform.

In plain English

Analytics tags, advertising pixels, heatmap scripts, chat widgets. Each sends data somewhere, and each adds weight to the page.

Tags accumulate. Most sites carry several nobody can account for, from tools cancelled years ago, all still loading on every page.

A tag audit typically removes several dormant scripts and measurably improves load time. It also finds the duplicate analytics tag that has been double-counting conversions.

Common mistakes

×Never auditing installed tags.
×Duplicate analytics tags double-counting.
×Tags for cancelled tools still loading.
×Adding tags directly to templates rather than through a manager.
