A pixel is an analytics tool that allows you gauge the effectiveness of ads, track actions on your site, and build audiences.
It’s really just a simple line of code added to a website that tells you what users are on your site and what they’re doing on it (anonymously, of course). And each pixel you add to your website can have a monumental impact on how you approach your digital marketing strategy.
With a variety of pixels out there, what pixels do you need and how to install them is a common question.
