PXTA is short for Pixel Tracking Audit. Take the P and the X from pixel, the T from tracking, the A from audit. Say it letter by letter, or “pix-ta” if you prefer. Both work, and the site lives at pxta.com either way.

The X needs explaining, and so does the pixel. “px” has stood for pixel for decades: it’s the unit in every CSS width and every image editor’s ruler, so a developer reads PX and thinks of screens. The pixel part needs a little history, because a tracking pixel was once literally one pixel.
