It is important to note that GZIP, software based on the deflate algorithm , has different quality levels , 9 to be exact, which balance the compression level with the speed at which the latter occurs . It starts from philippines phone number list the first level which corresponds to a reduced file compression, but at a very high compression speed, up to the ninth level with the maximum file compression, but at a relatively slow speed.
You can enable GZIP on Apache through the .htaccess file or enable GZIP on Nginx by setting the nginx.conf file correctly. If you have no idea how to do it and you have a site made in WordPress you can use the WP Rocket plugin that automatically adds the compression rules.
If you have enabled GZIP compression correctly , when the browser visits the website, it checks whether the response header “ content-encoding: gzip ” exists on the server. Once the header is detected, the server then provides the compressed files , otherwise it proceeds with the non-compressed ones. So how do you check if you have enabled GZIP compression correctly?
There are several ways to check if compression is enabled: you can use the free GZIP compression test tool where you will have to enter your website and click on “Check”. At this point you will be able to see how much data has been saved after compressing the page , or you will receive an error message that will report that GZIP is not enabled on your site.
Another option to check if GZIP compression is active is to use GTmetrix , one of the best tools to test the speed of your website. The tool is easy and intuitive, to analyze the page you just need to insert the corresponding link. If GZIP compression was not enabled correctly, the tool will show warnings and messages to report errors.
