URL Blocking

To measure the performance impact of a particular resource (CSS/Image/JavaScript) on a Web Page, ⚡️ SpeedVitals has the URL Blocking Feature.

This feature can be accessed from the ⚙️ More Options Button.

In Block URLs Text Field, you need to enter one URL per line. This field also accepts wildcard.

Here are some examples:

Block Google Analytics
https://www.google-analytics.com/analytics.js
Block All resources from JSDelivr CDN
https://cdn.jsdelivr.net*
Block All Images from a WordPress Site
https://www.example.com/wp-content/uploads*
Block All Resources from all Subdomains of google.com
*.google.com*
Block all PNG Images
*.png
Block all CSS Files
*.css
caution

Make sure you only enter One URL Per Line. Press the Enter/Return Key to go to the next line. You can enter a maximum of 10 URLs in this field.

Here's an example of how the text field should look like if multiple URLs are blocked:

Block Google Analytics & Facebook Pixel
https://www.google-analytics.com/analytics.js
https://connect.facebook.net/en_US/fbevents.js
