What is Gzip compression?

Gzip compression refers to a website being compressed. Smaller files are sent from the server to the visitor’s browser, allowing the website to load faster. This improves the overall site speed. Gzip compression can be implemented in several ways, with mod_deflate or mod_gzip as the methods of choice. All modern browsers support Gzip compression.

There are several ways to compress data like images, text, stylesheets, and scripts. For example, minifying JavaScript, CSS and HTML. This means that in the source code, elements like unnecessary characters, spaces and white lines are compressed.

What does the AdResults Gzip compression test tool do?

The AdResults Gzip compression test indicates whether a page is offered to the browser in a compressed form. The test also shows how large the page would be with and without compression enabled. Also visible is the percentage of page size saved.

Note: activating Gzip increases the load on the server (as the CPU usage increases), but the gain is almost always larger than the increase in CPU usage. Gzip compression saves data traffic since smaller pages are downloaded. Furthermore, Gzip compression ensures that pages load faster (especially on devices with a slow internet connection) and that the server has fewer open connections (since pages are downloaded faster by users).
