Any file—whether it’s an image, CSS file or JavaScript file—that’s hosted on a domain that is not yours is considered, ‘3rd-party.’ It’s very likely you’re using at least one of them: social media widgets, YouTube videos, Google fonts, or Google Analytics are only a few examples of what we mean with 3rd-party content.

When GTmetrix, Pingdom, or PageSpeed show warnings for these kinds of files, you have to be aware you can’t optimize them, because they live on a server that you have no control over.

In this video will dive deep into the concept of external content, and we’ll explain how it can hurt the performance of your site.
